Orthodox Dogmatic Teaching and Its Varieties in the Development of Modern Greek Theology

Abstract

This paper examines the evolution of modern Greek Orthodox dogmatic theology, highlighting its transition from early twentieth-century scholasticism to the diverse neo-patristic and existential approaches that shaped its later renewal. It begins with Panagiotes Trembelas, whose comprehensive but manualist synthesis safeguarded doctrinal continuity while limiting historical and experiential depth. After the Second World War, Greek theology encountered Russian émigré thought and rediscovered the Palamite tradition, inspiring a “return to the Fathers” and a search for authentic patristic expression. This movement produced multiple trajectories: John Romanides emphasized historical and experiential purification, Christos Yannaras redefined dogma as personal and relational existence, and John Zizioulas developed a Eucharistic and relational ontology grounded in communion. Rather than representing rupture, these approaches reflect a creative struggle to articulate Orthodox faith within modern intellectual contexts. Overall, this paper presents modern Greek dogmatics as a dynamic field negotiating tradition, modernity, and ecclesial identity.

1. Introduction

The study of Orthodox dogmatic theology in the modern Greek context is a vital field for understanding both the theological renewal and the identity crises that have characterized the Orthodox Church since the 19th century. While Orthodox theology traditionally regards itself as the faithful continuation of the patristic tradition, the reality of modernity—defined by political independence, the rise of nation-states, and the encounter with Western thought—has compelled Greek theologians to rearticulate dogmatic truths in light of new intellectual, social, and ecclesial challenges. This paper situates Orthodox dogmatic teaching and its varieties within the development of modern Greek theology, focusing particularly on the twentieth century and on the theologians Panagiotes Trembelas, Christos Yannaras, John Romanides, and John Zizioulas. Modern Orthodox theology cannot be understood apart from its historical consciousness and Orthodox thinking since the mid-nineteenth century has sought to emerge from the ‘Western captivity’ of its thought, to restore its patristic authenticity, and to respond creatively to modernity (Yannaras 1972, p. 199; Yannaras 2006, pp. 203–4; Zizioulas 1985, p. 25; Ladouceur 2019a, pp. 124–25). In the opening decades of the 20th century, Greek theology remained, as Norman Russell observes, “dominated by an arid scholasticism” that echoed post-Tridentine Catholic manuals rather than the spirit of the Greek Fathers (Russell 2006, p. 77). This scholastic ethos offered a systematic but lifeless presentation of Orthodox dogma, divorced from historical and existential depth. The theological landscape began to change after the Second World War, with the rediscovery of the Palamite synthesis and the reception of Russian émigré theology—particularly through figures like Vladimir Lossky and Georges Florovsky. This “return to the Fathers” movement sought to recover Orthodoxy’s patristic core and to liberate it from what Florovsky termed its “Babylonian captivity” to Western categories. However, the movement was not monolithic, it produced diverse trajectories within Greek theology, ranging from conservative Neo-patristicism to radical reinterpretations of dogma through existential and phenomenological categories (Pantelis Kalaitzidis 2024, pp. 522–24).

This renewal belongs to a wider project of de-Westernization and can be interpreted as both a theological and cultural act of self-definition. According to Kalaitzidis, the rediscovery of theosis and the emphasis on apophaticism became identity markers for modern Orthodoxy, offering a distinctive language of divine–human communion that resisted the rationalism and moralism of the West (ibid., p. 522). Yet this same project risked turning into an ideology of “Orthodox exceptionalism,” especially when it hardened into anti-Western polemics. Although younger theologians—particularly those shaped by the so-called theology of the 1960s in Greece—often tend to undervalue the earlier generation of scholars such as Panagiotes Trembelas, this dismissive stance was fully embraced and even systematized by Christos Yannaras in his influential work Orthodoxy and the West. Yannaras’s critique, while intellectually stimulating and emblematic of broader theological shifts in modern Greek thought, risks oversimplifying the contribution of figures like Trembelas, whose work, despite its scholastic limitations, preserved doctrinal continuity during a period of profound cultural and ecclesial transition. In my view, a more nuanced assessment would recognize that the achievements of the theology of the 1960s in Greece were made possible precisely because it stood on the foundations laid—however imperfectly—by the older generation it so readily rejected. The 1960s generation marked a decisive turn toward the so-called “neo-Orthodoxy.” This movement combined theological retrieval with philosophical engagement, embracing existentialism and personalism as vehicles for rearticulating Orthodox dogma in contemporary terms. These thinkers, while deeply rooted in the Fathers, rejected both the scholasticism of the previous theological generation and the pietistic moralism of the brotherhoods, insisting instead on the experiential, ecclesial, and relational nature of theology.1

By the early twenty-first century, Greek theology had diversified into several modes—neo-patristic orthodoxy, neo-orthodoxy, neo-traditionalism (monastic conservatism), and a new post-patristic theology. All four claimed fidelity to Orthodoxy’s tradition, yet they differed in theological assumptions, interpretative methods, sources of authority, and sociocultural stance. Neo-patristic thinkers like Metropolitan John Zizioulas sought to renew Orthodox theology by returning to the Church Fathers in a creative way. They assume the patristic heritage holds answers for modern existential questions if interpreted afresh. Zizioulas, for example, built a theology of personhood grounded in the Cappadocian Fathers, proposing that true being is communion. He famously argued that the concept of person (hypostasis)—understood as relational existence in the image of the Trinity—is Orthodoxy’s gift to the modern quest for authentic existence (Pantelis Kalaitzidis 2023a). The trend termed “neo-Orthodoxy,” exemplified by Christos Yannaras, also originated in the mid-20th-century Greek theological revival. It shares with neo-patristics a protest against dry, scholastic theology, but its focus is existential and cultural. Yannaras frames Orthodoxy as a holistic “way of life” (tropos), emphasizing the experiential reality of faith and the distinct ethos of the Christian East (Prevelakis 2013). Yannara’s ontology “reconfigures being through relation” identifying freedom not with autonomy but with communion and eros. In this perspective, the Church is the locus where being is realized as personal relation, a polis of communion that transcends individual substance (Milbank 2018, pp. 1–18). However, Yannaras also exhibits a structural anti-Westernism—whereby the distinction between theology and civilization becomes blurred (Pantelis Kalaitzidis 2008, pp. 357–58). His interpretation of Orthodoxy as the bearer of an authentic “Greek” mode of being often transforms the Church’s universal tropos into a civilizational ethos, idealizing Hellenism as the exclusive vessel of truth (ibid., pp. 321–55). This dialectic of East and West slides often “from the theological to the cultural and ethnocentric”, turning difference into antagonism. In this framework, the West becomes a theological counter-image—identified with individualism, moralism, and metaphysical nihilism—while the East alone embodies relational authenticity (ibid., pp. 383–89).

In stark contrast to the above, neo-traditionalist or monastic conservative theology insists on continuity and guarding the authenticity of Orthodox tradition. Its basic assumption is that the patristic and ascetic heritage is timeless and entirely sufficient; any push to re-interpret Orthodoxy is viewed with alarm. This reaction has become increasingly visible since the 1990s, as Orthodox Churches reasserted their role in post-communist societies. What emerges is a modern invention of “traditional orthodoxy”—a defensive identity marker that isolates Orthodoxy from pluralism and secularity rather than engaging them. The phrase “traditional Orthodoxy” first appeared in the 20th century within Old Calendarist circles. It soon became a polemical slogan against ecumenism and “Western corruption.” Figures such as Photios Kontoglou and Constantine Cavarnos helped transform “tradition” from a dynamic process of discernment into an ideological category of opposition—a theological weapon that defines Orthodoxy by what it is not (Demacopoulos 2022, pp. 7–18). In this way, the defense of tradition became a form of anti-modern protest, fusing theological purity with cultural and political conservatism. This transformation distorts the very nature of tradition (paradosis). For the Fathers, tradition was the living experience of the Spirit within the Church’s communion, not a static deposit but a continuous participation in divine life. In fundamentalist rhetoric, however, tradition becomes a fixed canon, a defensive fortress that defines Orthodoxy by exclusion. Thus, neo-traditionalism freezes the living stream of tradition into a monument of the past (Asproulis 2020, pp. 185–88).

2. The Dogmatic Edifice of Panagiotes Trembelas

Panagiotes Trembelas holds a distinguished place in the history of 20th-century Greek theology, even though his contributions have not yet been fully recognized. Born in 1886, he earned his doctorate in theology in 1908. A man of remarkable erudition, Trembelas would go on to exert a decisive influence on theological and ecclesiastical life for more than half a century (1918–1957). Owing to his dynamic character and exceptional abilities, he successfully advanced through every stage of academic life at the Theological School of the University of Athens, where he pursued a distinguished academic career (Asproulis 2016a, pp. 15–18; Bebis 1978, pp. 323–25; Spiteris 1992, pp. 227–41; Nichols 1999, p. 98; Bonis 1978). His writings span thousands of pages and include, among other works, an almost complete series of interpretative commentaries on the Old and New Testament (with the exception of Revelation), which constitute a true treasure trove of patristic exegesis—perhaps the most comprehensive series of commentaries in modern Greek theological literature, comparable in scope to the renowned foreign series (Karakolis 2016)—and his dogmatic studies, foremost among them the three-volume Dogmatics of the Orthodox Catholic Church, which was also published in French (Trembelas 1966). This monumental work, notable for its rich array of patristic references, remains unique in its kind, as it represents the first complete systematic Dogmatics in modern Greek theology. In addition, Trembelas’s Encyclopedia of Theology demonstrates his profound familiarity with Western theological thought, while his original liturgical studies further attest to the breadth and depth of his scholarship (Trembelas 1992, pp. 83–119); (Foundoulis 2006); (Panagiotis Kalaitzidis 2023, pp. 123–61); (Tzerpos 2023, pp. 161–81).

In the Prolegomena to volume I, Trembelas defines dogmatic theology as the scientific exposition of the faith in the Church, an exposition verified not only by Scripture but also by the polyphonic concord of the Fathers. He explains that the Orthodox theologian must combine the historical and analytical methods with the systematic and synthetic ones (Trembelas 1959, pp. 35–43). Thus, he not only traces the gradual clarification of each dogma but also orders them into a coherent whole. Trembelas rejects both the fragmentary historicism of Protestant scholarship and the abstract rationalism of late scholasticism. The purpose of theology, he insists, is not speculation but the safeguarding of revealed truth within the living body of the Church. The methodological preface also reveals the scope of his ambition. He sought to provide a manual that would present every article of faith “authentically and indisputably,” anchored in Scripture and the Fathers. His criticism and skepticism toward mysticism are striking, as he states that “the aberrant mysticism of the heretics, which seeks immediate communion with God and union with Him through worldly detachment, the suppression of the intellect, and the emotional exaltation of the soul, is not devoid of pantheistic implications.” (ibid., pp. 148–49). Although he criticizes Augustine and the filioque, he nevertheless seems to have accepted several elements of Roman Catholic theology, including Aquina’s notion of God as actus purus and the doctrine of satisfaction of divine justice.2 Regarding anthropology, Trembelas appears to base his thought on the classical definitions of the Church Fathers. Created in the image of God, human beings possess reason and intellect, through which they imitate their Creator. From God, humanity received mind and rational judgment. Free will serves as the necessary complement to reason and intellect, making virtue not a matter of necessity but of deliberate choice (ibid., pp. 490–93). Nevertheless, Trembelas expresses strong reservations concerning human desire and sexuality, maintaining that human reproduction could have existed without desire—an inclination he therefore regards as inherently sinful (ibid., p. 507).

The second volume opens with the explanation of the mystery of Redemption. Trembelas writes that from a human perspective, the Incarnation of the Word appears as a necessity—particularly in view of divine justice, which demands satisfaction from the transgressor for the offense committed. For this reason, according to the Fathers, it was necessary for the incarnate Word to die for humanity, so that humankind might be redeemed. This is also how Trembelas understands redemption, as he continues to expound the theological positions of Anselm of Canterbury and Thomas Aquinas, with whom he largely agrees, seeking to unite their insights into a coherent synthesis (Trembelas 2003, pp. 38–39). The lengthy exposition of the hypostatic union reaffirms Chalcedonian orthodoxy. Against Nestorius, he stresses the unity of the person; against Monophysites, he stresses the integrity of the two natures (ibid., pp. 81–116). The communicatio idiomatum is carefully explained, and the properties of each nature are shared in the one hypostasis, allowing the human to become the instrument of divine salvation. The result is a Christology that is both biblical and patristic but expressed in scholastic categories of nature, person, and operation (ibid., pp. 116–43).

Despite the harsh criticism Trembelas received for the difficulties arising from what may be considered his last extensive work, Mysticism–Apophatism. Affirmative Theology, one cannot fail to emphasize his balanced—a least in our view—approach to the relationship and distinction between affirmative and negative theology (Trembelas 1974). He rightly underscores the dangers inherent in an excessive reliance on the apophatic method, a tendency that had begun to prevail in theological thought at the time this particular work was written. Although Trembelas at times seems to dismiss too readily, and perhaps too severely, major theological figures such as the author of the Areopagitic writings or Symeon the New Theologian, it should nonetheless be noted that, grounded as he was in the biblical narrative, Trembelas could not adopt the extremes of apophatic methodology—extremes that often risk marginalizing the very revelation of God in history, as most clearly manifested in Scripture. Viewed in this light, Trembelas’s work—and his characteristically Christocentric outlook (Nichols 1999, pp. 100–2), despite its acknowledged limitations—should be assessed positively, especially in contrast to the rising currents of extreme apophaticism that, as if in a new kind of “Babylonian captivity,” once again threatened to obscure the historical and eschatological horizon of Christian theology (Asproulis 2016a, pp. 34–35). In assessing P. Trembelas positively, one might also, in our view, include his critical engagement with certain aspects of patristic thought—particularly in cases that his opponents would later regard as “criteria of Orthodoxy.” Although the following observation may seem somewhat exaggerated, we hold that Trembelas, despite his occasional one-sidedness or scholastic rigidity, at times appears to perceive the dangers to which the absolutization of the theological heritage—such as that of Gregory Palamas (in the tradition of Pseudo-Dionysius the Areopagite)—can lead, especially concerning the celebrated distinction between divine essence and energies. It is well known that, especially since the mid-20th century, this theological distinction, together with the broader theology of Gregory Palamas, has stood at the center of scholarly attention. This began primarily with the proponents of the so-called “neo-patristic synthesis,” led by Fr. John Meyendorff and Vladimir Lossky, and continued with a large number of academic and non-academic theologians in Greece—particularly through the work of the Patriarchal Institute for Patristic Studies at the Vlatadon Monastery in Thessaloniki and the publication of Palamian writings under the initial direction of Professor P. Christou. Within this context, the figure and theology of Gregory Palamas have come to be regarded, to a greater or lesser degree, as a symbol of Orthodoxy—so much so that one may now speak of a distinct “neo-Palamite theology.” (ibid., pp. 37–38). This exuberant absolutization of Palamas gives the impression that Orthodox theology essentially reached its culmination and came to a standstill in the 14th century, as though its subsequent task were merely to repeat what had already taken place from the beginning of the patristic era up to that point. Thus, the “return to the Fathers” is often understood as a return to a pre-modern Byzantine era in which Orthodox theology supposedly attained its highest development. Yet, in reality—and in accordance with the very nature of theology as a scientific discipline—critical reflection remains legitimate, even with regard to Fathers of the stature of Gregory Palamas.

The very strength of Trembelas’s synthesis—its order and completeness—also marks its limitation. However, while Trembelas fills these categories with Orthodox content, the structure remains “manualist,” favoring logical coherence over historical development. The Fathers are cited as proof-texts rather than as living interlocutors (Bathrellos 2023, pp. 239–67); (Ware 1971, pp. 477–80). The result is a theology of synthesis rather than of encounter. This methodological dependence explains the contrast between Trembelas and later “neo-patristic” thinkers. Whereas Florovsky and Zizioulas sought to retrieve the dynamic thought of the Fathers as an event of experience, Trembelas systematized it into propositions. His vision of theology as scientia fidei echoes the older ideal of a sacred science rather than the existential communion of person and truth emphasized by later generations. Trembelas’s criterion of truth is unanimity—the consensus of Scripture, Councils, and Fathers. While this secures doctrinal stability, it leaves little room for legitimate development. Theological creativity becomes suspect; history is treated as the mere unfolding of fixed propositions. Hence, Trembelas appears as a “pre-modern, post-patristic” theologian: post-patristic not because he rejected the Fathers but because he froze them into monuments. It is evident that Trembelas represents the final stage of a confessional paradigm: Orthodox theology as defense against heterodoxy and modernity rather than dialogue with them. His engagement with Roman Catholic and Protestant theology is mainly polemical. He borrowed their methods but aimed to refute their conclusions. Thus, his Dogmatics is both bridge and barrier—a bridge in its scholarly apparatus, a barrier in its lack of historical empathy.

3. Reconfiguring Orthodox Dogmatics: The Theological Project of Christos Yannaras

A versatile and multifaceted thinker, Christos Yannaras (1935–2024) extended his theological reflection across almost every field of the humanities, becoming a true landmark in modern Greek theology. Born in Athens, he studied theology and philosophy in his native city, as well as in Bonn and Paris. Although repeatedly rejected by the Theological School of Athens, after holding academic posts in Paris, Geneva, and Lausanne, he was eventually elected professor of philosophy at Panteion University, where he taught for two decades (1982–2002) (Abatzidis 2009, pp. 33–34). The author of roughly eighty books—many translated into more than ten languages—Yannaras engaged theology with philosophy, sociology, political theory, modern epistemology, political economy, and even literature. Through his work, he transformed theological thought into an active interlocutor with every current of modern Greek intellectual life, whether or not these currents agreed with his theological (and broader philosophical) perspective. With Yannaras, the aesthetic—as well as the intellectual—paradigm of modern Greek theology underwent a radical transformation. Greek theology began to abandon its narrow intellectual confinement and to open itself confidently to the mystery of thought and beauty. Its style became more assured, its concerns more creative, and its horizon more profoundly existential and socially engaged. A substantial portion of Yannaras’ oeuvre is ultimately apologetic in nature, seeking to establish a dialogue between Orthodoxy and philosophy, science, literature, art, and politics. He devoted particular attention to the Areopagitic writings, Maximus the Confessor, and the mystical/ascetic tradition, striving to reveal the existential depth of the Orthodox heritage and its enduring relevance to the contemporary world (Vlantis 2024). His doctoral dissertation, The Ontological Content of the Theological Concept of the Person—later expanded and published under the title Person and Eros (Yannaras 2007)3—stands at the very center of his thought. In this work, the concept of the person emerges as the ontological core of being, both in God and, potentially, in humanity, while the theological revelation itself is elevated to a “mystical” encounter with the very reality of God.

Yannaras’ principal dogmatic work—one that could even serve as a handbook of Orthodox dogmatics—is Elements of Faith (Yannaras 1991). Yannaras’ intention was to introduce the reader to the language of Orthodox dogmatics, free from the legalism and Western theological influence evident in the works of Trembelas—an influence he explicitly criticizes in his multifaceted study Orthodoxy and the West (Yannaras 2006, pp. 208–11). The book is “a primer of faith” rather than a treatise. Yet this brief book distills the logic of all his theology. It does not seek to convince or to convert but to distinguish what a Christian faith is from what it is not. The audience is the educated modern reader cut off from the experiential roots (Yannaras 1991, xiv). The opening chapter contrasts empirical certainty with the questions that science cannot answer. Yannaras observes that modern civilization “aims at objectivity”, yet human experience always bursts beyond the limits of the measurable. In those moments, the word “God” emerges spontaneously as a name for the mystery of relation. Existential questions are those that remain unanswered by science, and when at some point a “malfunction” or breakdown comes to the fore, the human being inevitably finds himself in an impasse. At that point, science can offer no answer, and the void—the chaos—is revealed (ibid., p. 3).

Humanity’s approach to God is threefold: religious fear, philosophical reason, and the personal relation of revelation. Only the third gives birth to faith as trust. At this point, however, certain difficulties emerge, particularly Yannaras’ view of the Old Testament as a purely historical text. As he himself notes, the Hebrew tradition is, in its very nature, a historical one (ibid., pp. 7–8). He proceeds to interpret certain persons and events as belonging not to the domain of historical reality, but to that of theological thought. Yet it appears that Yannaras employs this contrast between the ancient Greek tradition, founded on observation, and the Jewish tradition, grounded in history, as a means of reinforcing his theological argument.4 Yannaras’ attitude may, in fact, be interpreted as a reaction against the project of demythologization; he has explicitly declared his preference for Heidegger—that is, for a philosophical–existential approach to reality—over that of Bultmann (Grigoropoulou 2008, pp. 53–56). Faith, Yananaras insists, does not mean blind obedience; he uses the example of commercial “credit” (πίστις)—trust in a merchant’s reliability—to show that faith is personal fidelity (Yannaras 1991, p. 11). For him, faith is “an event and experience of relationship, a road radically different from intellectual certainty and ‘objective’ knowledge.” (ibid., p. 13). Yet, if faith is constituted as personal experience, it necessarily bears the mark of subjectivity. The experience of relationship is not a universal datum but an individual and incommunicable mode of existence, conditioned by personal consciousness and context. Consequently, this subjective dimension resists codification into doctrines or theological systems that claim to represent divine reality in universally valid terms. In this sense, the experiential and relational character of faith, as Yannaras defines it, may undermine the very possibility of a common theology, since what is lived and experienced cannot be fully shared or objectified.

Yannaras asserts that “what we call today dogma, appeared only when heresy came to threaten the experience of the ecclesial truth.” (ibid., p. 15). From a theological perspective, this reflects the Orthodox understanding of dogma as a safeguard of lived communion rather than speculative doctrine. Yet, from a historical point of view, this formulation oversimplifies the complex reality of early Christianity. In the first two centuries, there was no single, cohesive “ecclesiastical experience,” but rather a plurality of Christian movements—Jewish-Christian, Gnostic, Marcionite, and proto-orthodox—each claiming apostolic continuity and possessing its own theological vision (Pelikan 1971, pp. 69–76). What became “orthodoxy” was not the original or universally accepted form of Christianity but the tradition that eventually consolidated institutional authority and defined its rivals as heresies (Ehrman 2003, pp. 1–20, 174–82). Dogma, therefore, did not merely defend a preexisting unity of faith but also created and codified that unity by establishing normative boundaries amid theological diversity. In this sense, the emergence of dogma represents both a reactive response to internal conflict and a constructive process of identity formation within the early Christian world.

The chapter devoted to apophaticism articulates a central principle of Yannaras’ theology, one that permeates his entire theological vision: “apophaticism means our refusal to exhaust knowledge of the truth in its formulation” (Yannaras 1991, p. 17). For him, as he asserts elsewhere, apophaticism “constitutes a transcendence of the methodology of the speculative knowledge, not only the analogical approach of cognition through affirmations and negations, but also the inductive approach of causality.” (Yannaras 2005, p. 74).5 Yannaras elevated the apophatic conception of truth to the rank of the distinctive sign of Orthodox tradition; however, this absolutization of apophaticism distorts the patristic balance between faith and reason. The historical accuracy of making apophaticism the unique hallmark of the Fathers is questionable. The Cappadocians, Maximus the Confessor, and John Damascene, though conscious of divine transcendence, never eliminated the cataphatic dimension of theology; they integrated philosophy and rational reflection within their spiritual experience. Moreover, the spiritual preparation demanded by patristic writers for theology coexisted with deep philosophical culture. Far from rejecting reason, the Fathers made use of the scientific ideas and philosophical currents of their time, employing hermeneutical and logical tools for theological exposition. While apophaticism remains a legitimate dimension of theology, it cannot serve as its foundation or as Orthodoxy’s cultural identity. Theologians must recover the dialogue between revelation and reason, theology and history, faith and culture (Pantelis Kalaitzidis 2012).

Some of the finest pages in the book are devoted to the doctrine of the Trinity, which Yannaras presents in a vivid and dynamic manner, seeking to reveal its relevance to human life today. For Yannaras, “the God of the Church is the God of historical experience, not the God of theoretical assumptions or abstract syllogisms.” (Yannaras 1991, p. 20; See also Yannaras 2007, pp. 253–55).6 The divine being is not a self-contained essence or an individual substance; it is communion, a mode of existence constituted by relationship (See also Yannaras 2007, pp. 253–55). The radical break lies in the identification of hypostasis with person. For the Church Fathers, the person is the concrete hypostasis of being. It is through personal existence that being becomes real. This represents a decisive shift in thought: being is no longer seen as something self-evident or predetermined by essence, but as something that comes into existence through a free and relational act of personal existence (ibid., pp. 33–34). This understanding of the person is crucial not only for the doctrine of the Trinity but also for human life itself. It provides the foundation for a new way of relating to others and for a new mode of existence proposed by Orthodox theology and dogma. Just as the divine persons exist only in relationship—with the Father, Son, and Spirit defined by communion—so, too, are human beings called to realize their existence through relationship, freedom, and love, rather than through isolation or individual autonomy. The Trinity, viewed by Yannaras, points to the fact that the causal existence of what exists is not a necessity but a matter of personal freedom—the supreme and existential affirmation of freedom itself. For this reason, the only definition of God found in the Christian Bible is that “God is love.” Love, therefore, is not a moral attribute of God, nor merely a characteristic or behavioral quality—it is His very essence. God exists because He loves, and to the extent that He loves. Hence, these three words that constitute the revelation of the ecclesial Gospel—Father, Son, and Spirit—do not signify ontological individuality but rather relationship (ibid., pp. 35–36). This Trinitarian communion, far from being an abstract dogma, becomes the ontological key to every other reality. Because the divine life is freedom and love, creation itself is the overflow of that communion. Humanity, made in the image of the Trinitarian God, is called to realize the same mode of being—to exist not as an autonomous individual but as a person in relationship.

Equally noteworthy are the pages in which Yannaras reflects on the world and on humanity. Here, he repeatedly enters into dialogue with the science yet seeks at the same time to examine critically the impasses to which the scientific worldview can lead—especially when it absolutizes the study of the natural world and neglects the metaphysical needs of the human person. Particularly striking are Yannaras’ precise and nuanced definitions of fundamental theological concepts. Regarding the term energy, he writes: “What do we designate by the word energies? We designate those potentials of nature or essence through which the hypostasis and its existence are made known, rendered manifest and participable.” (ibid., p. 43). Similarly, he defines salvation as “the liberation of life from corruption and death, the transformation of mere survival into existential fullness—the participation of the created in the mode of life of the uncreated.” (ibid., p. 48). Finally, his understanding of asceticism reveals the ethical and relational depth of his thought; according to him, asceticism is “the struggle to renounce my egocentric tendency to view everything as neutral objects, subject to my needs and desires.” (ibid., p. 49).

The mystery of the Incarnation is presented as the decisive revelation of personal ontology. In Christ, divine and human nature coexist in the unity of the person, thus healing the rift between created and uncreated existence (ibid., pp. 89–95). For Yannaras, salvation is not a juridical transaction but a transformation of the very mode of being. Christ did not come to change God’s attitude to man but to change the whole human being, to transform the way in which humanity exists. By assuming human nature, the Word of God abolishes mortality and corruption, introducing into creation the mode of existence proper to divine love—freedom and communion. The Incarnation is the victory over necessity, since in the person of Christ life is no longer conditioned by corruption or by the biological process of death (ibid., pp. 95–98). This theology reaches its culmination in the Resurrection, described as the eighth day of creation—the beginning of a new ontological order in which the human person participates in divine life. Life after resurrection is no longer bound to biological necessity but transfigured into the freedom of communion. In Christ, the world and history acquire their ultimate meaning as the possibility of communion with God (ibid., pp. 109–20). Yannaras extends the logic of the Incarnation into his ecclesiology. The Church is not a moral institution or an abstract idea but the renewal of life. It is the continuation of Christ’s Incarnation—the mode of divine communion historically enacted (ibid., pp. 121–22). For this reason, the Eucharist stands at the center of ecclesial life. The Eucharistic assembly is the place where the world is restored to communion with God. The transformation of bread and wine does not signify a change in substance in a material sense, but an existential change in mode through thanksgiving; the created world becomes the body of communion (ibid., pp. 128–30). The faithful, by partaking, become members of one body, the body of Christ, sharing the same life and freedom. The Church therefore embodies the ontology of communion revealed in Christ. As the gathering of persons in the Holy Spirit, it anticipates the eschatological fulfillment of creation; the Church experiences the Kingdom here and now as an event of communion. Through baptism, eucharist, and communal love, human beings participate in the divine mode of being and overcome the fragmentation of individuality (ibid., pp. 146–48).

Yannaras inaugurated a new era by radically reconfiguring the very meaning and purpose of dogmatics. His thought is marked by a unique combination of patristic inspiration and existential immediacy. The positive dimension of his work lies in his creative renewal of Orthodox theology. By recovering the category of the person as the ontological center of existence, he liberated theology from sterile intellectualism and restored its existential and relational depth. In Elements of Faith, as well as in Person and Eros, he redefined dogma not as intellectual formula but as lived communion, making theology once again a language of life and love. His synthesis of the Trinitarian vision, the ontology of communion, and the Eucharistic experience opened new horizons for theological reflection. Moreover, his ability to bridge theology, philosophy, and culture gave Orthodoxy a vital public voice in contemporary thought, proving that faith can coexist with critical reasoning and aesthetic sensibility.

Yet Yannaras’s work is not without significant tensions and limits. His radical apophaticism, while profound, risks dissolving theology into ineffable subjectivity and undercutting the possibility of shared doctrinal expression. The emphasis on experience and relationality, though liberating, sometimes neglects the historical and communal processes through which faith and dogma were shaped. His critique of Western Christianity often lapses into cultural dualism, reducing complex traditions to simplified oppositions between “Orthodox” and “Western” thought. Furthermore, his tendency to identify Orthodoxy almost exclusively with apophatic mysticism overlooks the rational, ethical, and historical dimensions of the patristic legacy. For all its brilliance, his theology can appear abstract and elusive, emphasizing existential experience at the expense of historical concreteness. Nonetheless, even these weaknesses bear witness to the creative risk of a theologian who sought to make faith a living encounter between being, truth, and love.

4. John Romanides and the Therapeutic Turn in Modern Orthodox Dogmatics

The theological legacy of Professor and priest John Romanides is perhaps the most far-reaching in the modern Greek Orthodox world, as he left behind disciples such as Fr. Georgios Metallinos (1940–2019), Professor of Church History at the National and Kapodistrian University of Athens, and Metropolitan Hierotheos (Vlachos) of Nafpaktos (b. 1945), who continued, developed, and disseminated his thought both within Greece and abroad. It is noteworthy that most of his works have been translated into English and have exerted considerable influence on Orthodox Christians outside Greece, particularly in the United States. At this point, an instructive parallel may be drawn with Christos Yannaras. Whereas Yannaras’ writings primarily circulated within Greece—nourishing a distinctly Greek intellectual and cultural sensibility that often combined elements of Byzantine nostalgia and anti-Western critique—Romanides’ work inspired a different kind of emphasis, the conviction of Orthodoxy’s superiority over Western, especially Latin, theology. In his view, Western Christianity, rooted in Augustine and Scholasticism, represents a deviation from authentic theological experience, while Orthodoxy alone preserves the true therapeutic path of salvation—purification, illumination, and deification (κάθαρσις–φωτισμός–θέωσις). Romanides thus presents a comprehensive and holistic system, one that appeals not only for its theological coherence but also for its capacity to address historical and cultural questions. Romanides’ biography is available through numerous publications and online resources (Metallinos 2003); (Sopko 2003); (Metropolitan of Nafpaktos Hierotheos (Vlachos) 2008, pp. 25–93); (Romanides 2004, pp. xiv–xv). Here I will concentrate on his dogmatic theology as it is systematically articulated in his major work Dogmatic and Symbolic Theology of the Orthodox Catholic Church (Romanidis 1999).

Fr. John S. Romanides’ dogmatic theology represents one of the most radical attempts in modern Greek theology to recover the inner logic of patristic dogma as a living therapeutic tradition rather than a speculative system. Romanides insists that Orthodox dogmatic theology is not a branch of philosophy but the vitality of revelation itself, the expression of the empirical experience of the prophets, apostles, and saints. He opens his work by declaring that the entire task of theology is to guide the reader in the understanding of the dogmatic theology of the Holy Scriptures, the Holy Fathers, and the Ecumenical and Local Synods of the Church, a goal that can be achieved only through the patristic theological method, which is identical with that of the prophets and the apostles (Romanidis 1999, pp. 5–6). This method, he adds, has no relation with the speculative and dialectical method of philosophy and of Franco-Latin scholastic theology. Theology, therefore, is neither intellectual speculation about God nor metaphysical deduction from first principles but the direct fruit of deification (θέωσις)—participation in divine glory through the purification (κάθαρσις) and illumination (φωτισμός) of the heart.

Romanides’ central claim, which gives unity to his entire dogmatic system, is that religion is a neurobiological illness, and Orthodoxy is its therapy (ibid., pp. 10–12). The shocking formulation serves as a key to his anthropology. Religion, in his vocabulary, means every human attempt to identify the uncreated with the created—every form of idolization of human concepts and symbols about God. The disease of religion is the short-circuit between the spiritual sense located in the heart and the reasoning faculty of the brain. In a healthy state, he explains, the spiritual energy (νοερά ἐνέργεια) circulates within the heart in prayer; in the diseased condition, it becomes enslaved to the imagination and the environment, confusing the thoughts of the brain with divine reality (ibid., p. 10). The task of the Church is to heal this short-circuit through the ascetic process of purification, illumination, and glorification (ibid., pp. 12–14). Hence dogmatic theology is inseparable from spiritual therapy. For Romanides, this therapeutic anthropology is not a modern innovation but the essence of church itself. Within the Church, participants are classified according to the degree of their spiritual purification and perfection—namely, into the enlightened and the glorified (ibid., p. 15).7 According to him, revelation is empirical, not propositional; consequently, dogmas are not philosophical definitions but signals that are entirely pastoral in nature and cannot exist apart from the process of healing the heart through purification and illumination (ibid., pp. 27–28). The sacraments, ascetic life, and the entire canonical structure exist for this therapeutic purpose, while the exclusive purpose of the dogmatic definitions issued by the Ecumenical and Local Councils was, and continues to be, the safeguarding of the faithful within the therapeutic process of purification, illumination of the heart, and deification and their protection from the errors of non-Orthodox and even formally Orthodox spiritual physicians (ibid., p. 37).8 In this perspective, apostolic succession is not merely canonical ordination but the succession of illumination and theosis. Romanides states that the “principle that bishops must be chosen from among the deified has always remained a fundamental premise of Orthodox Tradition, strongly upheld by St. Dionysius the Aeropagite and preserved until nineteenth century. Over time, however, those who had attained deification became increasingly detached from the ranks of the parish clergy and began to be found primarily among the ascetics and monks. These monastic communities became the centers for preparing candidates for the episcopate and, above all, for the presidency of the synods.” (ibid., p. 38). The passage inaccurately attributes early episcopal principles to Dionysius the Areopagite, ignoring the fact that these works are pseudonymous and date from the late 5th century. It promotes a narrow view of Church leadership by idealizing monastic ascetics while disregarding the historical role of parish clergy in episcopal ministry. Furthermore, it reduces the synodal function to therapeutic goals, omitting vital doctrinal, pastoral, and administrative roles. The dismissal of intellectual theology as “stagnant moralism” reflects an anti-intellectual bias that contradicts the patristic tradition, which upheld a profound integration of reason and spiritual experience in the path to theosis.

This therapeutic realism shapes not only Romanides’ understanding of salvation but also his understanding of Trinitarian dogma. The dogma concerning the Holy Trinity and the Incarnation of the Logos became known to the prophets and the apostles by the revelation of the natural glory and divinity of Christ in both the Old and the New Testament Through deification, they came to know the uncreatedness of the Holy Trinity, both of Its essence and Its energies, and also the incommunicable properties of the divine persons (ibid, pp. 195–96). Romanides anchors the unity of God in the communion of uncreated energy and the distinction of persons in their hypostatic properties. Drawing from the Cappadocians, he affirms that everything the Father has, the Son has likewise, and all that belongs to both is also proper to the Holy Spirit, who is the perfect and uncreated image of the Son, just as the Son is the uncreated image of the Father (ibid., p. 197). Romanides contrasts this patristic understanding with the errors of the Eunomians and later Latin scholastics, who identified God’s essence with a single act of being and thereby destroyed the experiential distinction between essence and energy (ibid., pp. 194–96). Against them, he argues that the equality of the Son and Spirit with the Father is demonstrated by the identicalness of their uncreated energies, for if the divine operations were different, their divinity would not be one (ibid, p. 194). He explains that the “Kingdom of God” revealed in Scripture is not a created reality or future reward, but the eternal uncreated glory and majesty in which the Holy Trinity eternally dwells. This same divine glory is what appeared to the prophets, was incarnated in Christ, and will be revealed to all at the end. This glory is the very Kingdom of God, the manifestation of divine love that simultaneously deifies and purifies. Romanides follows St. Gregory Palamas in identifying the Kingdom with the uncreated light seen at the Transfiguration, where the apostles momentarily shared in the same vision granted to the saints. The “Kingdom” is therefore the uncreated energy of the Trinity, participated in by the saints according to their capacity. In this view, the Trinity and the Kingdom are inseparable. The Kingdom is the radiant communion of Father, Son, and Spirit overflowing into creation. The saints, by theosis, enter this Kingdom even now, the unrepentant experience the same uncreated energy as consuming fire. Thus, for Romanides, eschatology, Trinitarian theology, and mystical experience converge; the Kingdom is the eternal life of the Trinity revealed as uncreated light, love, and glory (ibid., pp. 187–89).

Fr. John Romanides’ Christology unfolds as the natural continuation of his Trinitarian theology and follows the same therapeutic and empirical framework. He begins by affirming that the pre-existent Christ, the Λόγος (Logos), is identical with the Lord of Glory who appeared to the prophets of the Old Testament. This means that the revelation of God throughout Scripture is Christological from the beginning; the pre-incarnate appearances of God are theophanies of the Logos Himself (ibid., pp. 199–200). Against Arian and Eunomian interpretations, which regarded the divine manifestations as created symbols, Romanides insists that the prophets truly saw the uncreated glory of the divine Logos, not a created sign (ibid., pp. 211–13). In several passages, Romanides contrasts the orthodox Christology with the rationalist tendencies of Western theology. According to him, the Western tradition, influenced by Augustine and the later scholastics, reduced revelation to created symbols and thus separated grace from the divine energies (ibid., pp. 218–19). For the Fathers, by contrast, the Creator who appeared to the prophets is the same Lord of Glory who became incarnate for our salvation (ibid., p. 216). However, Romanides overstates its case by misrepresenting Augustine’s views on divine knowledge, implying he teaches rational access to God’s essence, which Augustine explicitly denies.9 The critique also neglects the depth of Augustine’s mystical theology and mischaracterizes his Christology by implying a confusion between visibility and createdness.

He argues that the salvific power of this union is communicated through the uncreated energy radiating from Christ’s glorified body. The Transfiguration, Resurrection, and Pentecost are not symbolic events but empirical manifestations of this energy. In the Transfiguration, the apostles received a foretaste of the uncreated glory; in the Resurrection, that glory filled even the body, making it incorruptible; and at Pentecost, it was shared with the entire Body of Christ, the Church (Romanidis 1999, pp. 221–22). The difficulty with Romanides’ position is that, alongside his critiques of Arianism, Nestorianism, and Monophysitism, he develops a sweeping theory in which Augustine becomes the origin of nearly every doctrinal distortion in the West. According to Romanides, beginning with Charlemagne and the Council of Frankfurt (794)—which he regards as illegitimate—Augustinian theology gradually permeated the entire Franco-German world. With the rise of the so-called “Franco-Latin papacy” in 1046, this influence, he argues, spread throughout the rest of the West, except for what he calls the “subjugated Roman populations” of France and Italy. In Romanides’ view, the later medieval rediscovery of Aristotle only deepened the problem, producing scholastic theology—a synthesis of Augustine and Aristotle most fully expressed in the Summa Theologica of Thomas Aquinas. This “Augustinian-Aristotelian-Thomistic” reshaping of Christian tradition, he claims, eventually reached the Orthodox world—first through Russia from the fifteenth century onward and then, through Russian influence, entering the Greek Church after the War of Independence (Demacopoulos and Papanikolaou 2008, pp. 30–33).

It is noteworthy that in his book on Dogmatic Theology, Romanides devotes almost no space to the subject of ecclesiology. One may conclude that this omission reflects his distinctive understanding of the Church as a therapeutic reality rather than an institutional structure. For Romanides, the Church is not primarily defined by its external or organizational form but by its function as a spiritual hospital in which purification, illumination, and deification take place. As a result, he shows little interest in developing a systematic or structured ecclesiology in the conventional sense. His ecclesiology emerges from his broader theological framework, which grounds all dogmatic expressions in the empirical experience of the glorified saints. Consequently, the Church is not primarily a juridical institution or visible hierarchy, but the Body of Christ composed of those participating in the uncreated energy of God through purification, illumination, and deification or glorification. He argues that not all members of the visible Church are members of the Body of Christ unless they are on the path to glorification. This leads to an exclusivist ecclesiology in which spiritual experience becomes the primary, if not sole, criterion for ecclesial membership.10 Moreover, Romanides’ undervaluation of institutional structures and canonical authority creates a sharp and unsustainable dichotomy between the “historical Church” and the “Body of Christ.” This downplays the importance of apostolic succession, hierarchical order, and sacramental unity affirmed by the Ecumenical Councils. Apart from this, his ecclesiology is ahistorical in its romanticized view of the “pure patristic Church.” It fails to appreciate the diversity and development of Church life across various times and cultures. His rigid critique of post-Byzantine theology as “Westernized” ignores the reality that Orthodox theology has always engaged with broader intellectual currents, including the use of categories and terminology that evolve over time. Today, the biggest problem created by this type of ecclesiology is the monasticization of the Orthodox Church, the reaction to the decisions of the hierarchy, the devaluation of the parish clergy, and the belief in elders, since monasticism is necessarily considered the culmination of Romanides’ system and since monks are those who devote themselves entirely to prayer and the pursuit of deification. By defining the true Church as those participating in theosis through purification, illumination, and glorification, Romanides shifts the ecclesial focus from institutional structures and sacramental visibility to the ascetical and mystical life, historically most exemplified in monastic communities. This situation enforces an ecclesiology based on elderism and obediency. Romanides, though not directly responsible, contributes the theological foundation for such a posture and the creation of a mystical elitism that isolates the Church from the world.

Romanides, redirected Orthodox dogmatics toward the language of therapeutic experience. He sought to restore the living patristic experience of theology as a therapeutic science grounded in katharsis, photismos, and theosis. Yet this powerful retrieval of the ascetic core of Orthodoxy is simultaneously undermined by his historical reductionism and his tendency to conflate theological insight with polemical ideology. Romanides successfully reintegrated dogma, spirituality, and experience within a single therapeutic paradigm, but in doing so, he transformed theology into a closed medical anthropology, subordinating all doctrinal, ecclesiological, and historical dimensions to the language of healing. His claim that “religion is a neurobiological illness and Orthodoxy its therapy” may function as an evocative metaphor, but as a theological thesis it collapses the ontological and the spiritual into a biological register that borders on pseudo-scientific rhetoric. This terminology, while rhetorically effective, replaces theological reasoning with medical diagnosis and thus narrows the intellectual horizon of theology itself. At a deeper level, Romanides’s thought reveals an unresolved tension between his empirical aspirations and his ideological framework. He claims to restore the empirical method of the prophets and apostles, yet his reading of history and theology is shaped by an a priori dualism between Orthodoxy and the West. His theology, though conceived as therapeutic realism, operates as a polemical system. By reducing Western theology to pathology, he inadvertently mirrors the very rationalism he condemns, constructing an all-encompassing explanatory model that leaves no space for ambiguity, development, or self-critique. The result is a dogmatic edifice that is at once profoundly Orthodox and profoundly sectarian.

5. Person, Freedom, Communion: The Dogmatic Vision of Zizioulas

The role of John Zizioulas in contemporary Orthodox theology is one of the most creative and formative moments in the contemporary theological scene. Born in 1931 in Katafygio, Kozani, he studied theology at the universities of Aristotle University of Thessaloniki and National and Kapodistrian University of Athens, and later continued his studies at Harvard University and the Ecumenical Institute of Bossey. In the late 1960s and early 1970s, he was Secretary of the Faith and Order Commission of the World Council of Churches, where he was actively involved in inter-Christian theological dialogue. Zizioulas also taught Orthodox ecclesiology and sacramental theology at Bossey, and later held academic chairs in Edinburgh and Glasgow, before being elected Metropolitan of Pergamon in 1986. His theology, which was deeply influenced by the patristic tradition, proposed a unique ontology of person and communion that aimed to address modern philosophical thinking, while remaining grounded in the ecclesial experience of the Church (Pantelis Kalaitzidis 2023a; Asproulis 2016b, pp. 33–59). Zizioulas did not merely repeat the Fathers but reactivated their ontology within the existential and ecclesial horizon of contemporary humanity. His theological synthesis seeks to reconcile ontology and ecclesiology, eschatology, and anthropology, showing that theology is not abstract speculation but a lived experience of communion. Zizioulas’ central achievement lies in the articulation of a relational ontology, rooted in the Eucharistic experience of the Church. In contrast to the substantialist metaphysics of Western scholasticism, Zizioulas, following the Cappadocian Fathers, affirmed that “being” is constituted as communion (κοινωνία). The ultimate foundation of existence is not substance but person (πρόσωπο), and the agent of being is the personal existence of the Father. Thus, ontology is transformed into an event of communion; “to be” is “to be in relation.” In this sense, Zizioulas offers an ontology of freedom and love, one that bridges theology and anthropology, the Trinity and the Church (Asproulis 2025, pp. 59–67, 71–74, 83–89) (Metropolitan Ignatios of Demetrias and Almyros 2016, pp. 299–303). The entire thought of Zizioulas is marked by this Eucharistic paradigm: the Church, as the Body of Christ gathered in the Eucharist, is not a moral or institutional society but the revelation of eschatological communion. The bishop, as presider of the Eucharist, becomes the icon of the eschatological unity of the faithful. Thus, ecclesiology for Zizioulas is neither sociological nor purely mystical; it is ontological and eschatological (Metropolitan Ignatios of Demetrias and Almyros 2016). In this chapter, we will examine the dogmatic theology of John Zizioulas as presented in his work Lectures in Christian Dogmatics (Zizioulas 2008). In this book, the renowned Orthodox theologian offers a systematic introduction to the Christian faith, demonstrating that the doctrine of God is inseparable from the Church, the living community that manifests divine love and communion. For Zizioulas, the formulation of doctrine is the Church’s way of expressing this love to the world, inviting human beings to share in the communion of the Father, Son, and Holy Spirit.

For John Zizioulas, the very meaning of doctrine cannot be detached from the Church’s concrete, communal life. Doctrine, in his view, is not an abstract system of theological propositions but the Church’s mode of existence expressed in words. It is the teaching of the Church insofar as it arises from, and returns to, the Church’s eucharistic and pneumatological experience. Consequently, Christian doctrine is what the Church says in its worship of God. Thus, it articulates the experience of communion with God and with one another; it is the verbal form of a lived reality (Zizioulas 2008, p. 4). Doctrine, for Zizioulas, is also hermeneutical. It is not the repetition of ancient formulas but their interpretation within new historical and cultural contexts. In this perspective, Christian teaching has a dynamic continuity; it transmits the faith of the Fathers but reinterprets it for every generation, remaining faithful to the Church’s tradition while avoiding sterile repetition (ibid., p. 3; see also (Vasiljević 2025)). Theology has no autonomous or private sphere, because the truth it articulates belongs to the life of the body of Christ. The Church, through its communal life, determines not merely the content but the very form of doctrine (ibid., pp. 6–7). Zizioulas’ epistemology is profoundly relational (Papanikolaou 2008, pp. 131–42). Knowledge of God is possible only in communion, because God is known as a personal being-in-communion. To know God is not to possess information about a divine essence but to enter into a relationship of mutual self-giving between God and the believer, mediated by the Church. This emphasis overturns the Western epistemological model that begins from individual subjectivity; because the Church is the community of those united to Christ by the Spirit, all authentic knowledge of God arises within her and is verified in her life of communion (Zizioulas 2008, pp. 12–13).

In Zizioulas’ view, the relationship between Scripture and dogma is not one of “sources of revelation”—a post-Reformation dichotomy alien to Orthodoxy—but one of interpretation and continuity. The Bible is not an external authority to which the Church submits, but the Church’s own witness to its encounter with the living God. Dogmas are not additions to Scripture but its ecclesial interpretation. The Church’s dogmas are commentaries on the apostolic experience recorded in Scripture. Revelation is not a set of timeless propositions but the event of communion between God and the Church. Hence, the authority of dogma is not juridical but pneumatological. A doctrine becomes a dogma only when it passes through the Church’s conciliar consciousness and is received by the whole body. The formula “It seemed good to the Holy Spirit and to us” (Acts 15:28) defines the ecclesial character of every true dogma. The criterion of truth is not logical consistency but the presence of the Spirit within the communion of believers (ibid., pp. 9–12. See also (Zizioulas 1997, p. 17)).

The doctrine of Trinity is very center of Christian faith, the key that discloses what it means to exist at all. According to our theologian, the God of the Gospel is not an impersonal essence shared by three individuals but the personal life of communion itself. As he writes, “for Israel God is personal…personal in the Old Testament we mean that he is acknowledged within relationships between persons” (Zizioulas 2008, p. 42). The early Fathers insisted that God’s threefoldness is intrinsic to His being. In contrast to the Greek philosophical conception of God as a monad—a solitary unit of pure being—Christian faith declares that the oneness of God cannot mean that God is a monad. The Fathers made the crucial distinction between solitary and one; God is one, but never solitary (ibid., p. 49). Zizioulas traces the decisive turn in theological history to the Cappadocian Fathers, who re-interpreted ontology itself through the revelation of the Trinity. Prior to them, classical thought identified being with ousia—a self-subsistent nature. The Fathers, however, introduced the idea that being exists only as person and in communion. In God, Zizioulas comments, “it is not divine nature that is the origin of the divine persons. It is the person of the Father that ‘causes’ God to exist as Trinity” (ibid., p. 53). Divine essence is not the source of being; the person of the Father is. Here lies Zizioulas’s decisive insight that the Father is the personal source (aἰτία) of divine being. The Cappadocians, he writes, found that “the person of the Father is the ultimate agent, but since ‘Father’ implies communion he cannot be understood as a being in isolation” (ibid., p. 53). The Father is not a metaphysical principle but a person whose very identity implies relationship; thus, “personal communion lies at the very heart of divine being” (ibid., p. 53). For Zizioulas, this trinitarian ontology reveals the deepest meaning of freedom. Freedom precedes essence even in God. Love and freedom are not moral qualities but ontological conditions. Zizioulas concludes that this trinitarian ontology defines not only God but humanity. Created nature will never turn into uncreated nature, but man can become a person in the image and likeness of the Holy Trinity. Human beings, too, are called to exist in communion and freedom. In learning again from the Cappadocian Fathers, theology “can replace the psychological conception of the person and teach us the meaning of the person from the doctrine of the Trinity.” (ibid., p. 69).

John Zizioulas’ Christology is grounded in his broader ontology of communion, wherein Christ is not merely the instrument of salvation but the actualization of a new mode of existence. Christ is the One who inaugurates the transition from biological to ecclesial existence, enabling humanity to participate in the Trinitarian life through communion. In this vision, Christ is the “new Adam” not just morally, but ontologically (Zizioulas 1997, pp. 98–102). He also situates Christology within the question of how creation, drawn from nothing, can be saved from nonbeing. The answer, he insists, is Christ as the mediator between created and uncreated (Zizioulas 2008, pp. 101–2). Zizioulas understands Christology not merely as a dogmatic boundary but as a key to ontology itself. The incarnation of the Logos is an ontological event that bridges the abyss between God and the World. Moreover, following St. Maximus the Confessor, he argues that the “incarnation is not simply a response to the Fall” but “the central requirement for the salvation of creation.” (ibid., p. 103). Thus, Incarnation belongs to God’s eternal plan, not as an afterthought to sin but as the very purpose of creation. In this perspective the Chalcedonian doctrine can be interpreted existentially. “Without divison” means that the created and the uncreated must be in genuine communion on the level of being, otherwise creation collapses into death. “Without confusion” preserves the freedom and otherness of the two realities; otherwise, communion would not be free. In Christ, communion and otherness coincide. His hypostasis is simultaneously divine and human, uniting the two orders while preserving their distinction (Asproulis 2025, pp. 101–2). A central feature of Zizioulas’s thought is the integration of Christology and Pneumatology as emphasized by Stavros Yangazoglou. He observes that the same relational ontology that defines the Trinity governs the relation of Son and Spirit in the economy. The Spirit, who proceeds from the Father and rests on the Son, constitutes Christ’s personal and ecclesial identity. The Spirit actualizes the Incarnation, transforming the historical Jesus into the risen Lord and making Him present in the Eucharist and the Church. In this sense, Christ’s person is never self-contained; it is pneumatologically open, extending to embrace the many. The Church is therefore the continuation of the Incarnation, Christ as corporate personality, in which the Spirit constitutes the many as one Body (Yangazoglou 2016, pp. 157–73).

Zizioulas treats eschatology not as the final chapter of dogmatics but as the hermeneutical key to all theology. For him, Eschatology is not an appendix to history but the revelation of history’s truth. The end is the criterion and cause of being itself (Zizioulas 2008, p. 153). For this reason, the future is not simply what comes last but that which determines what has been from the beginning. This inversion—seeing the future as the source of meaning—constitutes what Zizioulas calls an eschatological ontology.11 Nikolaos Asproulis writes about this approach and points out that “Zizioulas established the position that eschatology lies at the heart of the Church; that ultimately the eschaton ‘provides and grants her very identity’” (Asproulis 2025, p. 118). Zizioulas insists that eschatology must not cancel history but transfigure it (Zizioulas 2008, pp. 155–56). The Holy Spirit’s work is an invocation that keeps history open to the freedom of the future. The Church lives in the tension of already and not yet; the Kingdom is present as promise and anticipation, not a possession. This means that through the spirit, history remains open to the future and receives its truth from what is to come (ibid., p. 156). For Zizioulas, the Eucharist is the concrete manifestation of eschatology within history. The Church celebrates the Eucharist as the presence of the future—the coming Kingdom realized sacramentally in history (ibid., p. 157). The Eucharist allows the Church to live as an icon of the eschaton. Thus the Church is determined iconically by the future Kingdom. Zizioulas’s eschatology is also pneumatological; the Holy Spirit brings the future into the present. The Spirit’s presence is always the presence of the future; it makes the end operative within history and liberates the Church from the causality of nature and history, granting it a mode of existence not bound by biological or sociological necessity (Zizioulas 2008, pp. 156–57; See also Asproulis 2025, pp. 123–24). The integration of eschatology and ontology culminates in what Zizioulas calls an iconic understanding of being. Time and matter become “icons” of the future reality they anticipate. Liturgical time is time carrying within it the end of creation; it moves toward eternal life, not death. The icon does not abolish history but brings it into a dialectical relation with eternity. In this sense, every act of the Church—especially the Eucharist—is a participation in the transfiguration of the cosmos (Zizioulas 2008, p. 160). Zizioulas’s eschatology is not speculation about the afterlife but an ontology of communion and a theology of hope. It redefines time, freedom, and being through the perspective of the future (Vasiliadis 2016, pp. 90–91). The eschaton—the ultimate communion of creation with God—is already active within the Church through the Spirit. The Eucharist manifests this reality as the presence of the future, transforming history into an icon of the Kingdom. His vision transcends both secular immanentism and other-worldly escapism; the Kingdom is neither an ideal projection nor a distant reward but a foretaste and luminous glimpse in the life of the Church.

John Zizioulas’s ecclesiology cannot be understood apart from his ontological vision of the Trinity. For him, “the Church is the outcome of the Father’s will, a will he shares with the Son and the Holy Spirit, and which is realised through the economy in which each of the persons of God is engaged.” (Zizioulas 2008, p. 132). According to Asproulis, “the crucial connection between the Church and the Trinity” is addressed in Zizioulas’s work Being and Communion”, and “during this time, Zizioulas worked on constructing a communion/relational ontology from a personalist perspective and clarifying the essential dimensions of the church’s identity.” (Asproulis 2025, p. 116).12 Thus, the same relational ontology that defines the Trinity constitutes the Church, a communion of distinct hypostases. Consequently, the Church exists to make visible the divine life of communion within time and creation. This Trinitarian perspective allows Zizioulas to overcome individualism and institutionalism alike. The Church is not a collection of self-sufficient subjects, nor a collective organism determined by structure; it is a personal communion of freedom and love—a way of being that mirrors God’s own life. Zizioulas’s ecclesiology can also be described as Eucharistic. Purification cannot be separated from the Eucharistic transformation of creation. At times, greater emphasis is placed on personal purification than on Eucharistic communion, yet it is in the liturgical act of communion that our true relationship with God is revealed. The liturgy is the concrete enactment of our relationship with God, with the communion of the saints, and with the entire created world. Its purpose is not merely to produce a particular intellectual insight, emotional state, or mystical experience, but to make us participants in a shared life (ibid., pp. 124–26). This Eucharistic ontology leads to Zizioulas’s unique synthesis of the local and universal dimensions of the Church. Against any form of centralized ecclesiology, he argues that the fullness of the Church is found in every local Eucharistic assembly presided over by its bishop. Yet this local fullness exists only in communion with other local churches. The universal Church is therefore not an abstract body above the locals but the communion of the local Churches. This understanding preserves both unity and diversity. The unity of the Church arises from the communion of all the local Churches, while their diversity reflects the variety of the Spirit’s gifts. Ecclesiology thus becomes relational rather than administrative—a reflection of Trinitarian perichoresis (ibid., pp. 140–41). Zizioulas interprets episcopacy through this eucharistic and personal ontology. The bishop is not a bureaucratic authority but the icon of Christ in the community—the one who presides in the name of the Father and expresses the unity of the many. The presence of the bishop ensures that the Eucharist is not a private act but an ecclesial event encompassing all. Each bishop, as president of the local Eucharist, manifests the fullness of the one Church; the communion of bishops, in turn, manifests the unity of the Church throughout the world. The bishop in the Eucharist is the local Church in its entirety, and the communion of bishops is the universal Church. This structure is neither hierarchical domination nor democratic representation but a communion of persons; the bishop, the presbyters, and the laity together constitute one body. Their unity is not legal but sacramental—a unity grounded in the one Eucharist (ibid., pp. 145–48) (Bathrellos 2016, pp. 109–39). There is no hierarchy of essences between the universal and the local; catholicity is realized in each community that celebrates the Eucharist. This marks a fundamental difference from Western ecclesiology, which tends to place the universal Church above the local ones. The unity of the Church is not juridical but Eucharistic and conciliar—a communion of Churches bound together through their bishops in mutual recognition and love (Asproulis 2025, pp. 141–44).

The most creative synthesis emerges in the work of Metropolitan John Zizioulas, whose relational ontology and Eucharistic ecclesiology offered perhaps the most compelling bridge between patristic tradition and modern philosophical concerns. By rooting ecclesiology, Christology, creation, and salvation in a Trinitarian ontology of communion, he offers a vision of the Christian life that is at once patristic and contemporary, deeply liturgical yet strikingly existential. His theological system is coherent and elegant. It stretches from ontological foundations (personhood and hypostasis) to Christology (as the mediation of personhood), through soteriology (as the liberation from necessity and death), into creation theology (as Eucharistic gift), and culminates in eschatology (as the present reality of the future). In every case, Zizioulas reads Christian doctrines not merely as propositions but as ontological events, liturgically realized in the Eucharist, and centered on the Church as the space where the Trinity becomes existentially accessible. Despite these strengths, Zizioulas’ theology is not without important critiques, which come from theological, philosophical, and ecclesiological angles. It seems that his emphasis on ontology—particularly the ontological priority of personhood and communion—may come at the expense of the narrative and historical dimensions of Christian faith. The very strength of Zizioulas’s theological synthesis—its demand for internal coherence between ontology, ecclesiology, and anthropology—also exposes its main weakness. Because every element of his system must reflect the same Trinitarian logic, Zizioulas leaves little space for contradiction, ambiguity, or historical development within Christian existence (Pöysti 2020, pp. 50–53). His theology seeks a “total harmony” in which the life of the Church, human personhood, and divine being all participate in one symmetrical structure of communion. Yet such a totalizing framework can flatten the dynamic tension between creation and Creator and reduce praxis to the enactment of a pre-given metaphysical order. Robyn Shepherd observes that Zizioulas’s approach to the Cappadocians presupposes a living continuity of Orthodox consciousness in which the Fathers are not historical sources to be reconstructed but theological voices still speaking within the Church. This approach baffles many Western scholars because it subordinates historical method to ecclesial identity. The vision of Zizioulas may be coherent, but it risks circularity, since the same ecclesial framework that grounds his theology also determines its results. By assuming an unbroken patristic consensus, Zizioulas effectively insulates his thought from historical critique and projects modern relational categories back into the ancient context. Therefore, his method, while theologically fruitful, lacks sufficient methodological transparency and thereby limits his contribution to genuine East–West dialogue (Shepherd 2017, pp. 201–12). Nikolaos Asproulis, while praising Zizioulas’s creative retrieval of the Fathers, warns that his “relational ontology” over-accentuates the monarchy of the Father and turns causality into an ontological category. The result is a theology that “privileges the person of the Father as causal principle at the expense of divine equality” (Asproulis 2025, pp. 101–3). Thomas Ruston offers a nuanced critique of Zizioulas’s eucharistic ecclesiology in his discussion of the bishop’s role (Ruston 2021, pp. 39–58). He notes that Zizioulas’s portrayal of the bishop as the one who presides in the image of the Father succeeds in expressing the Church’s unity as communion rather than institution, yet it also exposes the model to what Ruston calls the “charge of projection.” (ibid., p. 39). By correlating the bishop’s presidency with the monarchy of the Father, Zizioulas risks translating Trinitarian causality into an ecclesial structure and thereby re-introducing a subtle form of hierarchy (ibid., pp. 41–44). Ruston acknowledges that Zizioulas explicitly rejects domination, but he cautions that identifying the bishop too closely with the local Church “lends itself to monarchical readings” and obscures the Spirit’s distribution of diverse gifts (ibid., pp. 46–52). To correct this imbalance, Ruston proposes a reparative synthesis in which episcopal ministry is understood within the totus Christus framework—the whole body’s participation in Christ’s eucharistic person—so that communion is grounded not merely in hierarchical presidency but in the pneumatological life of the entire community (ibid., pp. 54–58). Cyril Hovorun offers one of the most incisive structural critiques relevant to Zizioulas’s theology. In Scaffolds of the Church, he shows that many Orthodox ecclesiological models, by grounding unity in fixed hierarchies and ontological analogies, have transformed communion into structure. While he does not single out Zizioulas, his analysis of primacy and autocephaly clearly challenges the kind of personalist and ontological reasoning characteristic of Zizioulas’s Eucharistic ecclesiology. Hovorun notes that the principle of hierarchy can be useful, but it is not essential for the Church, since the early Christian ethos stemmed from the equality of the Father, Son, and Spirit rather than from domination (Hovorun 2017, pp. 138–40). When theology projects divine causality onto ecclesial offices, it risks turning relational symbols into pyramids of power. In his concluding reflections, Hovorun calls for a poststructural ecclesiology that moves from structure to relation, freeing the Church from ontological rigidity and ideological self-justification (ibid., pp. 195–98). In the end, Zizioulas’s legacy is both monumental and paradoxical. He re-anchored Orthodox dogmatics in the Eucharist and the Trinity, re-asserting that to be is to be in relation. Yet his very success provokes new questions about freedom, hierarchy, and history.

6. Conclusions

The development of modern Greek Orthodox dogmatic theology reveals a complex, dynamic, and often dramatic struggle for identity, authenticity, and renewal. Nevertheless, this apologetic stance had a historical function. Throughout the twentieth century, Greek theology has had to re-articulate orthodox faith in the context of modern nation-state culture, secularism, and the ongoing dialogue with Western intellectual traditions. What we find is not a linear progression from “error” to “purity,” but a continuing dialogue between dogmatic stability and ecclesial creativity, with the question being, how can we remain loyal to our patristic inheritance while speaking a language that can engage contemporary philosophical, social, and pastoral questions? Part of this process is the apologetic posture taken by Panagiotes Trembelas, and this had a real historical purpose. During the mid-century, as theological discourse was in danger of dissolving into pietistic moralism or positivistic reductionism, Trembelas’ dogmatic synthesis provided Orthodoxy with intellectual dignity and a comprehensive catechetical reference. But, again, this model has limitations in terms of dogmatic synthesis, which can be accomplished in a brilliant fashion while remaining tenuously connected to the historical dynamism of the Fathers and to the therapeutic reality which dogma finds in liturgy. Trembelas is best understood as a transitional figure, and what made him and his work valuable was what made renewal possible.

This stance, in turn, is the principal reason for the development of the neo-patristic revival of the post-war period. The return to the Fathers was not motivated by nostalgia for Byzantium but was, rather, a methodological imperative. Dogmatics must be re-anchored in the concrete ways of knowing God, namely, the Holy Scripture in the liturgy, prayer, ascetic struggle, and conciliar discernment. This return to the Fathers did not lead to the development of a new program but, rather, opened up a new space in which various developments took place, each of which claimed patristic inspiration but emphasized different facets of patristic theology, such as historical consciousness, existentialism, therapy, and communion. One of the most creative attempts at developing Orthodox dogma in terms of existentialism and personalism can be seen in the work of Christos Yannaras. By developing Orthodox dogma as the language of a lived “tropos of existence,” namely, freedom as communion rather than autonomy, he helped Greek theology break away from sterile apologetics. Even where tensions arise, such as in his absolutism regarding apophaticism and “the West” as a monolithic counter-tradition, his work is motivated by a vital concern—namely, Orthodoxy must prove that dogma is not metaphysics but rather the ecclesial disclosure of a new way of being.

In this perspective, we are still influenced by Romanides’s legacy, which cannot be dismissed. John Romanides rediscovered Greek theology’s awareness of the empirical and therapeutic aspects of revelation. At the same time, he reaffirmed the spirit of the Church Fathers that truth cannot be separated from sanctity. In emphasizing purification, illumination, and glorification, Romanides reconnected dogmatics with its ascetical and pastoral context. But modern theology has to transcend the categories of Romanides’ polemics in order to achieve a synthesis that encompasses the therapeutic view with a realistic view of history and culture. If the categories of “Orthodoxy vs. the West” dominate the discussion, spirituality can degenerate into ideology. Romanides can be considered indispensable as a rediscovery of ascetical realism but insufficient as a presentation of the full complexity of the Church.

A major attempt at synthesis can be seen in the thought of John Zizioulas. His relational ontology and Eucharistic ecclesiology offered a bridge between patristic thought and modern philosophical concerns in the assertion that being is fulfilled in communion. His emphasis on the relational nature of persons in the Trinitarian life and on the ecclesial identity in terms of Eucharistic community made clear that dogma is the Church’s reading of an event; the Spirit creates a communion of many in one in Christ. Discussion about the balance between history and ontology, or about possible “projections,” does not diminish this achievement, but makes clear that any major attempt at synthesis must remain self-critical in its historical awareness.

Ultimately, the ongoing task of Orthodox dogmatic theology is not the defense of static propositions but the articulation of how divine life becomes human life within the communion of the Church. The richness of the contemporary Greek theological landscape, with all its tensions and disagreements, is itself a sign that Orthodoxy remains a living tradition—one that continues to seek, in every age, the language through which the mystery of God may be known, lived, and proclaimed in the world. The most daring trend in early 21st-century Greek theology has been the “post-patristic” approach associated with theologians like Pantelis Kalaitzidis and Nikolaos Asproulis and the Volos Academy for Theological Studies (Ladouceur 2019a, pp. 150–51). This movement starts from the premise that Orthodox theology, to be true to its mission in the world, must continually adapt and respond to new historical contexts (Pantelis Kalaitzidis 2013, 2016, pp. 120–35). Far from seeing tradition as closed or complete, revisionist theologians view it as a living process—one that did not freeze after the Byzantine era. Their key assumption is that fidelity to the patristic legacy sometimes requires going beyond the exact formulations of the Fathers in order to address contemporary issues (hence the provocative term “post-patristic,” meaning after the patristic age, though not against it). They argue that the Orthodox theological tradition has always included contextualization; for example, the Fathers themselves engaged Hellenistic philosophy and the issues of their time (Pantelis Kalaitzidis 2010, pp. 14–15). In the 21st century, then, Orthodox theology should likewise grapple with modernity, postmodernity, science, democracy, and human rights.

The way forward is neither one of confessional closure nor one of uncritical adaptation, but rather a mature hermeneutics of tradition. Such a hermeneutics might enable us to appropriate Trembelas’s coherence of doctrine without lapsing back into scholasticism, learn from Yannaras’s sensitivity to human existence without succumbing to cultural polemic, benefit from Romanides’s therapy without succumbing to ideological reduction, and draw on Zizioulas’s Eucharistic ontology without neglecting history and the various charisms of the people of God. Orthodox dogmatics would then be what it has always aspired to be: a rigorously ordered articulation of the Church’s worship and healing for the sake of the world.
