A Nineteenth-Century Hungarian Denominational Conflict: The Controversy over “Re-Baptisms”

Abstract

For historical reasons, the Kingdom of Hungary was one of the most confessionally diverse states in Europe. The rapid spread of the Reformation, the exceptional religious pluralism of the Principality of Transylvania, and the Habsburg-era repopulation of territories reconquered from the Ottoman Empire produced a durable multi-confessional society in which different denominations often lived side by side within the same communities. Against this background, the religious affiliation of children born into mixed marriages became one of the most contentious church–state issues in nineteenth-century Hungary. Although Act LIII of 1868 sought to regulate the matter by assigning children to their parents’ denominations according to sex, many Catholic priests continued to follow canon law, requiring reversales or baptizing children contrary to the provisions of civil law. These practices—known in Hungarian public discourse as “re-baptisms” (elkeresztelés)—generated prolonged political, legal, and theological disputes involving the Catholic hierarchy, Protestant churches, the Hungarian government, and the Holy See. This article examines the historical origins of the controversy, the theological foundations of the Catholic position, the development of the reversalis system, and the political conflicts that culminated in the Hungarian Kulturkampf of the 1890s. It argues that the dispute was not merely a denominational conflict but a manifestation of the broader process of secularization, understood here primarily as the renegotiation of the respective competences of church and state in a modern constitutional order. Particular attention is devoted to the resolution of the controversy through the ecclesiastical policy legislation of 1894–1895, which introduced compulsory civil marriage and state civil registration, thereby removing the civil legal consequences of “re-baptisms” while leaving the Catholic Church’s internal doctrinal position fundamentally unchanged.

1. Introduction

The ecclesiastical policy debates of the second half of the nineteenth century constituted one of the most significant constitutional conflicts in the formation of the modern Hungarian state. The process of civil transformation involved not only the restructuring of the constitutional order, public administration, and the economy, but also a fundamental redefinition of the relationship between the state and the churches (C. Herger 2010). This issue proved particularly sensitive in a country whose religious landscape had been permanently shaped by the Reformation, the Catholic Reformation, and centuries of Habsburg confessional policy, resulting in a durable multi-denominational society.

Within this context, the religious affiliation of children born to mixed-confessional marriages extended far beyond the sphere of family law. A child’s denomination determined not only the religious community to which he or she belonged, but also the church in which religious instruction would be received, the ecclesiastical register in which the child would be recorded, and, in the longer term, the demographic balance and social influence of the respective denominations. Consequently, the issue was simultaneously theological, canon-law, constitutional, and political in nature. It is therefore unsurprising that disputes over mixed marriages repeatedly became subjects of parliamentary debate during the Reform Era and later in the Dualist period, eventually playing a decisive role in the enactment of Hungary’s ecclesiastical policy legislation of 1894–1895.

Underlying these conflicts were two partially incompatible legal systems. The Catholic Church regarded marriage as a sacrament instituted by Christ, whose essential characteristics included the unity of faith between the spouses and the Catholic upbringing of their children. Consequently, mixed marriages were considered permissible only as exceptional cases and under strict conditions. By contrast, from the late eighteenth century onwards the Hungarian state increasingly claimed legislative competence over matters relating to marriage, the religious affiliation of children, and the maintenance of civil registers. The resulting tension between canon law and state law became one of the defining legal controversies of nineteenth-century Hungary.

The present study examines the emergence and development of this distinctive legal and political conflict. It analyses the theological foundations of the Catholic position, traces the evolution of the system of reversales (written declarations concerning the religious upbringing of children) in Hungary, and explores how these developments culminated in the ecclesiastical policy reforms of the late nineteenth century. The analysis extends beyond the evolution of Hungarian law by placing the domestic debate within its broader international context, paying particular attention to the Prussian controversies over mixed marriages and to the successive interventions of the Holy See, both of which exerted considerable influence on Hungarian legislation and ecclesiastical practice.

The principal finding of this study is that the controversy over the so-called re-baptisms (Hungarian: elkeresztelések) cannot be understood merely as a denominational dispute. Rather, it represented one of the most significant Hungarian manifestations of the broader process through which the competences of the modern state and the Church were renegotiated. The case demonstrates that secularization should not be interpreted solely as the withdrawal of ecclesiastical influence from public affairs. It also encompassed the gradual expansion of state authority into areas that had previously fallen within ecclesiastical jurisdiction and had traditionally been regarded as matters of religion. In this sense, the controversy over re-baptisms transcends its immediate historical context. It provides valuable insight into the emergence of the legal relationship between the modern Hungarian civil state and the churches, while also contributing to a broader understanding of the constitutional and legal dimensions of state–church relations in nineteenth-century Europe.

2. The Confessional Landscape of the Kingdom of Hungary

The ideas of the Reformation reached the Kingdom of Hungary as early as the 1520s, primarily through students returning from German universities and through commercial contacts, as the country’s urban population and merchant class were largely German-speaking (Murdock 2000). The Reformation fundamentally transformed the confessional structure of the Kingdom of Hungary. Following the Battle of Mohács (1526), the political fragmentation of the country between Habsburg Royal Hungary, the Principality of Transylvania, and the Ottoman-occupied territories prevented the restoration of a uniform confessional order. Lutheran and subsequently Reformed communities became firmly established alongside the Catholic Church, while Transylvania developed an exceptionally plural confessional system. The resulting diversity was not merely demographic: different denominations developed and preserved their own ecclesiastical institutions and normative traditions. This became particularly significant in matrimonial law, where Catholic canon law and Protestant matrimonial norms coexisted within the same political community. The nineteenth-century controversies over mixed marriages must therefore be understood against the background of this historically developed plurality of ecclesiastical legal traditions (Kováts 1883).

Ottoman rule also played a distinctive role in this process. For the Ottoman administration, doctrinal differences among Christian denominations were of secondary importance, provided that their adherents acknowledged Ottoman authority and paid the required taxes. Consequently, Protestant churches often enjoyed greater freedom in Ottoman Hungary than in the Habsburg-ruled Kingdom of Hungary. Numerous Lutheran and Reformed congregations became firmly established during the period of Ottoman occupation, while Protestant ministers and schools operating in the occupied territories played a crucial role in the long-term consolidation of the Reformation (Greene 2002).

As a result, by the end of the sixteenth century the majority of the population of historical Hungary belonged to one of the Protestant denominations. According to some estimates, between 80 and 90 per cent of the population had become Protestant. The Catholic Church retained stronger positions primarily in western Hungary under Habsburg rule, around episcopal centres, and in Croatia, which had been linked to Hungary in a state union since 1102 (Murdock 2000).

Transylvania represented the opposite extreme. Following the Battle of Mohács, it developed into a Hungarian polity rivaling Habsburg Royal Hungary. Although it came under Habsburg rule during the eighteenth century, it retained a considerable degree of constitutional autonomy until the second half of the nineteenth century. The Diet of Torda in 1568 issued what has often been regarded as Europe’s first legal declaration of religious freedom, granting legal protection to the Roman Catholic, Lutheran, Reformed, and Unitarian denominations. Although the Orthodox faith of the Romanian population was not recognised as one of the officially accepted religions (religiones receptae), its religious practice and ecclesiastical organisation were tolerated. The same applied to the comparatively small but economically significant Jewish and Armenian communities (Hitchins 2014). Ottoman Hungary likewise became overwhelmingly Protestant, as the institutional structures of the Catholic Church had almost entirely disappeared from the occupied territories.

The seventeenth century witnessed both the Catholic Reformation and the Counter-Reformation. Although closely interconnected, the former primarily refers to the internal renewal and reform of the Catholic Church, particularly the implementation of the reforms of the Council of Trent, whereas the latter denotes the efforts to contain Protestant expansion and to restore Catholicism in territories where Protestantism had become established. Its leading figure in Hungary was Cardinal Péter Pázmány, Archbishop of Esztergom and Primate of Hungary. Pázmány recognised that Protestantism could be countered more effectively through education, culture, and pastoral work than through coercion alone. Under his leadership, the Catholic Church devoted considerable attention to founding schools, improving clerical education, and developing Hungarian-language apologetic literature. His most influential work, Guide to Divine Truth (Isteni igazságra vezérlő kalauz, 1613), became one of the most important Catholic apologetic writings of the period (Shore and Tusor 2020).

One of the principal factors behind the success of the Catholic renewal was the reconversion of the high aristocracy. During the seventeenth century, several of Hungary’s most influential noble families—including the Esterházy, Pálffy, and Forgách families—returned to Catholicism. Since landlords exercised extensive patronage rights over the religious life of their estates, their conversion frequently influenced the confessional affiliation of entire local communities. Through these patronage rights, the Catholic Church recovered numerous churches and ecclesiastical institutions that had previously belonged to Protestant congregations (Pálffy 2009).

The process was significantly facilitated by Habsburg state support. During the second half of the seventeenth century, the Viennese court increasingly regarded Catholicism as one of the principal foundations of political integration and dynastic loyalty. Particularly after the suppression of the Wesselényi Conspiracy (1664–1670), one of the major anti-Habsburg noble movements, measures restricting the activities of Protestant churches became more intensive. During the 1670s, numerous Protestant ministers and schoolmasters were brought before special tribunals, the most famous case being the trial of the Protestant pastors sentenced to the galleys in 1674. Although this period of persecution proved relatively brief, it significantly strengthened the cohesion and collective identity of Protestant communities (Evans 1979).

Nevertheless, the Counter-Reformation failed to eliminate Protestantism. The Reformed Church remained particularly strong in eastern Hungary and across much of the Great Plain. Debrecen, Sárospatak, and Pápa continued to function as major centres of Hungarian Calvinism (Murdock 2000). Likewise, the Lutheran Church preserved substantial influence in many parts of Upper Hungary, especially among the Slovak and German populations. Consequently, Hungary never returned to religious homogeneity but instead remained a permanently multi-confessional society (Kósa 1998).

Although the legal position of Protestants remained restricted during the early eighteenth century and opportunities for public worship were limited in many areas, the complete restoration of Catholic religious uniformity had become unrealistic. This was reflected first in the Treaty of Szatmár (1711), which concluded Rákóczi’s War of Independence, the most significant anti-Habsburg uprising before 1848, and later in Joseph II’s Patent of Toleration (1781). Joseph II, whose policies towards the Catholic Church were considerably less favourable than those of his Habsburg predecessors—notably through the suppression of numerous monastic orders—extended important civil and religious rights to Protestant communities (Ingrao 2019).

Another important factor shaping Hungary’s confessional structure was the large-scale repopulation of territories reconquered from the Ottoman Empire. Owing to approximately 150 years of Ottoman rule, prolonged warfare, and repeated military campaigns, extensive areas of central and southern Hungary became severely depopulated. Following the Habsburg reconquest, the government organised systematic settlement programmes to restore agricultural production and strengthen political control over the recovered territories. During the eighteenth century, large numbers of Roman Catholic German settlers (the Danube Swabians), together with Croats and other Catholic populations, migrated into the kingdom. These state-supported colonisation policies substantially increased the demographic weight of Catholicism, particularly in Transdanubia, the Banat, and the southern frontier regions, thereby reinforcing the confessional changes already initiated by the Catholic Reformation (Pálffy 2001).

By the end of the seventeenth century, the confessional map of Hungary had essentially assumed the form it would retain throughout the modern period. Transdanubia and most western regions had once again become predominantly Catholic, while extensive Reformed blocs characterised eastern Hungary and the Great Plain. Many areas of Upper Hungary remained predominantly Lutheran, whereas Transylvania preserved its distinctive multi-confessional character. Along the southern and eastern frontiers, substantial Orthodox populations were established, further reinforced by migration from the Balkans during and after the Ottoman wars. The religious policies and colonisation programmes of the eighteenth century built upon this confessional structure that had largely crystallised by the close of the seventeenth century (Murdock 2000).

These confessional divisions also possessed a marked ethnic dimension. By the mid-nineteenth century, the Reformed Church was almost exclusively associated with the Hungarian-speaking population. Hungarians also constituted the overwhelming majority of Roman Catholics in the central regions of the country, while the Unitarian Church remained almost entirely confined to Hungarian-speaking Transylvania. Germans and Slovaks were divided primarily between Roman Catholicism and Lutheranism, whereas Serbs, Romanians, and Ruthenians belonged predominantly to the Orthodox Church and, subsequently, in part to the Greek Catholic Church. According to the census data of the 1850s, Roman Catholics constituted approximately 49–50 per cent of the population, Reformed Christians 14–15 per cent, Orthodox believers 13–14 per cent, Greek Catholics 10–11 per cent, Lutherans 7–8 per cent, Jews 4–5 per cent, and Unitarians around 0.4–0.5 per cent. Moreover, these denominations rarely formed territorially homogeneous blocs; in many regions villages of different confessions alternated with one another, while elsewhere several denominations coexisted within the same settlement. This confessional diversity had important legal consequences, particularly in matrimonial matters. Marriage was not governed by a uniform body of law: the different denominations possessed their own ecclesiastical norms, while the state increasingly intervened in questions arising from the coexistence of these normative systems. Mixed marriages therefore constituted not merely a pastoral or denominational problem, but a particularly sensitive point of contact between different ecclesiastical jurisdictions and secular legislation. This legal pluralism formed the immediate institutional background to the nineteenth-century controversies examined in the following sections (Kováts 1883; Roszner 1887).

3. Debates over Secularization

In the decades before 1848, known in Hungarian history as the Reform Era, reform politicians took significant steps in the Diet and other political arenas towards the civil transformation of the country. This process accelerated during the Revolution and War of Independence of 1848–1849, when these forces briefly wrested power from the Habsburgs. Although their struggle was ultimately defeated as a result of Russian intervention, its achievements could no longer be entirely undone. Civil transformation, however, was an exceptionally complex process affecting countless areas of public and private life. Consequently, many issues remained open after 1848. Following the suppression of the revolution, the Habsburgs attempted to govern Hungary through absolutist rule. Owing to both internal and external developments, however, they reached a compromise with the Hungarian political elite in 1867. The Austro-Hungarian Monarchy was thereby established, and the restored Hungarian parliament once again gained the opportunity to legislate.

The application of general theories of secularization to nineteenth-century Hungary nevertheless requires some qualification. Models developed primarily from Western European historical experience cannot be transferred mechanically to the Hungarian case. The Kingdom of Hungary entered the modern period with a distinctive confessional and constitutional inheritance shaped by Ottoman rule, the separate development of Transylvania, Habsburg confessional policies, and the persistence of historically established rights and privileges of several denominations. Secularization in Hungary should therefore be understood not as a uniform process following a Western European trajectory, but as a historically specific renegotiation of the boundaries between state authority, ecclesiastical jurisdiction, and denominational rights. In this respect, the approaches of Casanova, Taylor, and Asad are employed here as general analytical frameworks rather than as models assumed to describe the Hungarian development directly (Máté-Tóth 2022).

One important element of this process of civil transformation was secularization: the demand for the separation of state and church. From the eighteenth century onwards, the Roman Catholic Church had effectively functioned as the state church. This situation was ended by Act XX of 1848, adopted during the revolution, which proclaimed the equality of the “legally received religions” and even included the Unitarians among them, thereby abolishing the Catholic Church’s privileged status as a state church (C. E. Herger 2024). The civil and political emancipation of Jews, who did not belong to this category, was later proclaimed by Act XVII of 1867. The new legal situation created by the 1848 legislation, together with the broader issues of secularization, partly brought to the surface sharp confessional tensions that had seemed to subside after the fierce religious controversies of the sixteenth and seventeenth centuries. Public life in this field was structured around three poles: the Catholic Church and its political sympathizers, the Protestant denominations and their supporters, and liberal politicians committed to secularization. Depending on the issue at stake, these groups either opposed one another or entered into temporary alliances. The Hungarian case therefore also cautions against identifying secularization simply with a linear decline of religion or ecclesiastical influence. As Miklós Tomka has emphasized in his analysis of Hungarian and East-Central European religious change, secularization theory alone is insufficient to explain the changing social position of religion; processes of modernization may coexist with the persistence, transformation, or even renewed public significance of religion. In the nineteenth-century context examined here, secularization is accordingly understood primarily as an institutional and juridical transformation of the relationship between churches and the state rather than as a straightforward process of religious decline (Tomka 2009).

These developments were also connected to the German Kulturkampf, which was traditionally followed with close attention in Hungarian public life. The German example, however, should not be regarded as a model that was simply reproduced in Hungary. Although contemporary Hungarian political discourse closely followed the Prussian Kulturkampf, the institutional and confessional setting of the Hungarian conflicts was substantially different. In Prussia, the confrontation developed primarily between the state and the Catholic Church and involved extensive direct state intervention in ecclesiastical organization. In Hungary, by contrast, church–state tensions unfolded within a historically multi-confessional legal order and were closely intertwined with relations among Catholics, Protestants, and other recognized denominations. The expression “Hungarian Kulturkampf” is therefore used in this study as a conventional historiographical designation for the ecclesiastical-policy conflicts of the 1890s, rather than to imply that they constituted a Hungarian version of the Prussian model (Rada 2019). After 1867, domestic political tensions in this field culminated in two specific issues: the religious affiliation of children born of mixed marriages and the introduction of civil marriage (Nagy 2025).

Marriage constituted a particularly sensitive area of this process because the expansion of state jurisdiction encountered a pre-existing claim of ecclesiastical jurisdiction. From the Catholic perspective, marriage between baptized persons was not merely a civil legal relationship but a sacrament and, as such, fell under the jurisdiction of the Church. The emerging modern state, by contrast, increasingly claimed competence to regulate the civil aspects and legal consequences of marriage. The nineteenth-century controversies over mixed marriages must therefore also be understood as conflicts concerning the boundaries between ecclesiastical and secular jurisdiction (Sipos 1960; Szabó 2008).

4. The Catholic Position on Mixed Marriages

The Catholic attitude towards mixed marriages—that is, marriages between a Roman Catholic and a member of another denomination—changed gradually over the course of history. The early Church did not prohibit such marriages absolutely, but strongly discouraged them. It feared, on the one hand, that the Catholic spouse might lose his or her faith, and, on the other, that the children born of such marriages would not be raised in accordance with Catholic doctrine. As early as the Council of Chalcedon in 451, it was prescribed that children born of mixed marriages should be baptized and raised as Catholics. The upbringing of children in another religion was, in practice, treated by the Church as an act directed against the faith (Gałkowski 2023).

This position became stricter in the Middle Ages. Canon 63 of the Fourth Council of Toledo in 633 expressly required that such children follow the Christian religion and threatened ecclesiastical penalties against parents who failed to ensure this. The issue, however, became a mass phenomenon only with the Reformation. The number of marriages between Catholics and Protestants increased dramatically, and the Holy See therefore permitted them only by special papal dispensation. By the eighteenth century, a more precise system of conditions for such dispensations had developed. These included the preservation of the Catholic spouse’s faith, a promise that all children would be raised as Catholics, and the consent of the non-Catholic spouse to these obligations (Gałkowski 2023).

In canon law, a marriage between a Catholic and a baptized non-Catholic was therefore not regarded as intrinsically invalid, but mixta religio constituted a prohibitive impediment (impedimentum prohibens). Such a marriage could be permitted by ecclesiastical authority through a dispensation, provided that the dangers associated with the confessional difference were sufficiently removed. Of particular importance were the cautiones, or guarantees intended to protect the Catholic party against the danger of losing the faith and to secure the Catholic baptism and upbringing of all children born of the marriage. The practice of requiring written promises, subsequently known in Hungary as reversales, thus formed part of a broader canonical mechanism designed to safeguard these conditions in mixed marriages (Sipos 1960).

A further canonical distinction is essential for understanding these controversies. The Council of Trent’s decree Tametsi (1563) introduced a prescribed canonical form for the valid celebration of marriage (Szuromi and Ferenczy 2011). In territories where the decree had been duly promulgated, Catholics were required to contract marriage in the presence of the parish priest, or another duly authorized priest, and witnesses. The territorial character of the decree was crucial: Tametsi did not acquire binding force everywhere merely by virtue of its adoption at Trent, but was to take effect in each parish only after its local promulgation. Consequently, where the decree had not acquired binding force, failure to observe the Tridentine form did not in itself invalidate a marriage. Such a marriage could therefore be canonically valid while remaining prohibited, or illicit, under Catholic ecclesiastical discipline (Erdő 1992). This territorial limitation was of particular importance in the Kingdom of Hungary. The political and confessional fragmentation of the country following the Ottoman conquest, together with the rapid spread and institutional consolidation of Protestantism, prevented the uniform promulgation and reception of the Tridentine decree. Although Archbishop Miklós Oláh sought to introduce the decrees of the Council of Trent in Hungary, their general reception advanced only gradually, particularly after the Synod of Nagyszombat (Trnava) in 1611 (Tarczaly 1935).

Consequently, in territories and parishes where Tametsi had not acquired binding force through promulgation or established observance, marriages contracted without the Tridentine form—including mixed marriages celebrated before a Protestant minister—could remain canonically valid, even though they were prohibited and therefore illicit from the Catholic perspective. This territorial diversity subsequently became a fundamental canonical background to the Hungarian controversies over mixed marriages. Consequently, in analysing mixed marriages it is essential to distinguish between validity (validitas) and liceity (liceitas): a marriage could be regarded as valid under canon law while nevertheless having been contracted illicitly (Schroeder 1941).

The difficulties resulting from the territorial application of Tametsi were addressed more systematically by Pope Benedict XIV in the declaration Matrimonia quae in locis of 4 November 1741. Originally issued for the Dutch provinces, the declaration recognized as valid marriages contracted between non-Catholics without observance of the Tridentine form, provided that no other canonical impediment existed. More importantly for the present subject, it extended this recognition to mixed marriages between Catholics and non-Catholics contracted without the Tridentine form. The so-called Benedictine Declaration thus provided an important canonical mechanism for accommodating the realities of confessionally mixed territories without removing the Church’s general prohibition of mixed marriages. Although originally issued for the Dutch provinces, the significance of the Benedictine Declaration extended beyond its immediate territorial scope. By separating the question of canonical validity from the Church’s continuing prohibition of mixed marriages, the Benedictine Declaration became an important component of the canonical framework governing marriages in confessionally divided territories. Its significance is particularly important for the present study because, unlike the Ne temere decree of 1907 and the 1917 Codex Iuris Canonici, it belonged to the body of canon law within which nineteenth-century controversies over mixed marriages actually developed. The Hungarian disputes must therefore be interpreted primarily within this pre-codification canonical framework, in which the validity of a marriage contracted without Catholic canonical form depended, among other factors, upon the territorial applicability of the Tridentine form (Cristellon 2019). This interpretation is also reflected in pre-Ne temere canonical scholarship: Gasparri’s Tractatus canonicus de matrimonio, in its 1904 edition, treated the territorial promulgation of Tametsi and the Benedictine Declaration as integral elements of the law governing the canonical form and validity of marriage (Gasparri 1904).

The most significant conflict between secular authority and Rome over this issue took place in Prussia, and it subsequently had important implications for other Catholic states, including the Kingdom of Hungary. In Prussia, a regulation had existed since 1803 according to which, in mixed marriages, children were required in all cases to follow the religion of their father. As a result, the Catholic clergy there also began to demand reversales, that is, written undertakings concerning the Catholic upbringing of children. The Prussian government therefore turned to Rome. Pope Pius VIII responded to Frederick William III with the brief Litteris altero abhinc anno. In it, he did not support an increase in the number of mixed marriages; indeed, he rejected in principle the consummation of marriages between persons of different confessions. Yet the social processes already underway could no longer be halted. As a compromise acceptable to both sides—the Protestant government and the Catholic clergy—the practice of passive assistance was adopted, meaning the celebration of the marriage without a priestly blessing (Anderson 2021).

The subsequent development of canon law falls outside the principal chronological scope of this study and is considered here only retrospectively, in order to indicate how the nineteenth-century framework was later transformed. The nineteenth-century controversies discussed here developed within the pre-codification canon law described above. Accordingly, the terminology and juridical categories employed in the following analysis—including impediments, dispensations, canonical form, validity, and liceity—refer to the pre-codification ius vigens applicable to the period under examination and should not be understood in the technical sense subsequently assigned to them by the 1917 or later Codes of Canon Law. The subsequent reforms are therefore relevant not as sources for reconstructing nineteenth-century law, but as evidence of its later transformation. In 1907, Pope Pius X issued the decree Ne temere, which introduced a more uniform regulation of canonical form. Mixed marriages contracted in violation of these rules—for example, in a merely civil ceremony or before a Protestant minister alone—were regarded by the Catholic Church as null and void, in the canonical sense. The decree generated considerable social and political tensions, since in several countries, including Hungary, it came into conflict with state legislation, especially because of the requirement of a written undertaking, and also created difficulties within mixed-confessional families (Larkin 1990).

This was followed by the first codification of canon law, the 1917 Codex Iuris Canonici, which declared that the Church “most strictly prohibits” mixed marriages. If such marriages were nevertheless contracted, the children had to be baptized and educated as Catholics, and those who knowingly raised their children in a non-Catholic religion could even incur excommunication (Coriden 2004).

For purposes of historical comparison only, it should be noted that the twentieth-century development of Catholic matrimonial law gradually modified this framework, particularly following the Second Vatican Council and Paul VI’s Matrimonia mixta (1970); these later developments, however, fall outside the chronological scope of the present study and are not used here to reconstruct nineteenth-century canonical doctrine (Noonan 2020).

5. Theological Foundations of the Prohibition and the Concept of Catholicity

According to several Protestant scholars, the Catholic restrictions on mixed marriages were not based exclusively on theological considerations. Some interpretations argue that the requirement that all children be raised in the Catholic faith also reflected the Church’s intention to preserve its membership, confessional identity, and institutional influence (Jameson 2014).

Nevertheless, the prohibition undoubtedly rested upon genuinely theological foundations from the Catholic perspective. According to Catholic doctrine, marriage is not merely the cohabitation of two individuals or a civil contract, but an institution established by God and, between the baptized, a sacrament. The purpose of marriage extends beyond procreation to include the mutual sanctification of the spouses and the establishment of a Christian family. Traditionally, the Church has understood the family as the ecclesia domestica (“domestic church”), the primary setting in which the Christian faith is transmitted, nurtured, and practiced (Second Vatican Council 1965).

Consequently, Catholic theology regarded as ideal a marriage in which both spouses professed the same faith, participated in the same sacraments, belonged to the same ecclesial community, and raised their children within a common religious tradition. Confessional difference was therefore viewed not merely as an administrative or institutional distinction, but as a factor that endangered the spiritual unity of marriage itself (Pope Leo XIII 1880).

Within this theological framework, the greatest danger associated with mixed marriages was considered to be the perversio fidei—the loss or corruption of the Catholic faith. The Church maintained that mixed marriages exposed both the Catholic spouse and the children to the risk of religious deviation, that is, estrangement from the Catholic faith and the acceptance of heretical doctrines, including Protestant teachings. Because marriage represents the closest of all human relationships, Catholic theologians believed that the non-Catholic spouse was uniquely positioned to influence the religious life of the Catholic partner. The concern therefore extended beyond the mere fact that one spouse was Protestant or Orthodox; rather, it centred on the possibility that daily family life might gradually weaken the Catholic spouse’s religious commitment. Differences concerning common prayer, church attendance, participation in the sacraments, and, above all, the religious upbringing of children were regarded as potential sources of conflict capable of undermining the unity of faith within the family. Conversely, Catholic theology viewed religious unity within marriage as a positive ideal, arguing that a family functions most harmoniously when its members share common religious values and participate together in the same spiritual life (Church et al. 1917).

The sacramental theology of baptism is equally important for understanding the terminology of the controversy. In Catholic doctrine, baptism is not merely an act of admission to a religious community but a sacrament that imprints an indelible spiritual character (character indelebilis) upon the baptized person and therefore cannot be repeated. Consequently, the expression “re-baptism,” widely used in contemporary Hungarian political and Protestant discourse, did not correspond to a Catholic sacramental category. From the Catholic perspective, a child who had validly received baptism could not subsequently be baptized again in the theological sense. The controversy concerned instead the confessional affiliation attributed to the child under state law and the competing claims of the churches regarding ecclesiastical membership and religious upbringing. The term “re-baptism” is therefore retained in this study as a historical designation, but placed in quotation marks to distinguish contemporary political and legal terminology from Catholic sacramental doctrine (Schroeder 1941).

An equally important theological consideration concerned the eternal salvation of the children born into mixed marriages. One of the most significant documents of the Second Vatican Council, the decree Unitatis Redintegratio (1964), marked a fundamental shift in the Catholic Church’s relationship with other Christian denominations. It abandoned the earlier tendency to regard Protestants and Orthodox Christians primarily as “heretics” or “schismatics.” Most importantly, while the Catholic Church continued to maintain that the fullness of Christ’s Church subsists within itself, it also acknowledged that baptized Protestants and Orthodox Christians are genuine Christians who belong to Christ. Consequently, they possess certain means of grace conducive to salvation, and the Holy Spirit is acknowledged to be at work within their ecclesial communities (Gałkowski 2023).

Before the Second Vatican Council, however, Catholic theology generally interpreted the principle Extra Ecclesiam nulla salus (“outside the Church there is no salvation”) in a far more restrictive manner. From this perspective, the Church considered itself responsible for those children who might have been raised within the Catholic faith—and thereby attain salvation—but instead grew up outside it. Canon law regarded the primary purpose of marriage not merely as the begetting of children but also as their proper upbringing. Such upbringing was understood not simply in terms of physical care or moral education, but above all as religious formation. Parents were therefore obliged to have their children baptized, provide them with religious instruction, and educate them according to Catholic doctrine. In mixed marriages, however, the Church feared that children would instead be brought up in a non-Catholic confession. For this reason, the requirement that the Catholic spouse ensure the Catholic upbringing of all children had already emerged during the Middle Ages. The later practice of requiring reversales—formal written undertakings guaranteeing the Catholic education of future children—and similar legal safeguards ultimately derived from this fundamental theological principle (Sullivan 2002).

From the perspective of the Catholic Church, the concept of catholicity itself should not be overlooked, as it is fundamental to the Roman Catholic Church’s self-understanding. Today, the Protestant churches in Hungary tend to use the term with caution. For example, in the Apostles’ Creed they translate the original Greek expression kath’ holon (“according to the whole”) as “universal,” believing that worshippers unfamiliar with Greek or Latin would associate the word “Catholic” primarily with the Roman Catholic Church rather than with the universality of the Church. The ecumenical movement, which emerged at the turn of the nineteenth and twentieth centuries largely through Protestant initiative, sought precisely to restore the original meaning of catholicity, presenting it as a concept embracing and reconciling the essential theological insights and traditions of Orthodoxy, Roman Catholicism, and Protestantism (Chalamet 2022).

The significance of the concept is further illuminated by the writings of Henri de Lubac, one of the leading Jesuit theologians of the twentieth century. According to de Lubac, catholicity simultaneously denotes unity, fullness, and universality. It is therefore not merely a matter of geographical extension but rather expresses the universality of Christ’s saving work. The Church is catholic because Christ died for all humanity, and because the Church is called to gather the whole human race into unity. Consequently, catholicity is not a statistical concept referring to the number of countries in which the Church is present, but a theological reality. From this perspective, the Church’s mission extends beyond the salvation of individual believers to the restoration of the unity of humankind as a whole (Lubac 1988).

Following the divisions of Western Christianity, this broader understanding of catholicity re-emerged only with the rise of the ecumenical movement at the turn of the nineteenth and twentieth centuries, a movement toward which the Roman Catholic Church gradually moved after the Second Vatican Council. Prior to the Council, Catholic ecclesiology identified the one Church of Christ with the Roman Catholic Church and therefore regarded it as the exclusive bearer of the fullness of catholicity. The churches that had emerged from the Reformation were not considered full participants in this catholicity but rather communities separated from the unity of the Church. Only the ecumenical renewal of the Second Vatican Council acknowledged that non-Catholic Christian communities also possess genuine elements of sanctification and salvation and that the restoration of Christian unity constitutes a common task. Viewed in this light, the nineteenth-century Hungarian controversies over mixed marriages and “re-baptisms” can be understood not merely as confessional or constitutional disputes but also as a historical manifestation of catholicity in practice. For the Catholic Church regarded the transmission of the faith and the Catholic upbringing of children as integral components of its universal mission to preserve and communicate the fullness of Christian faith (Kasper 2004).

These theological principles also had important juridical consequences. This understanding of the Church’s juridical autonomy was already clearly articulated in nineteenth-century papal teaching. In Immortale Dei (1885), Pope Leo XIII described ecclesiastical and civil authority as two powers, each supreme within its own sphere and possessing its own proper jurisdiction. He further characterized the Church, no less than the State, as a society perfect in its own nature and right, whose authority in matters pertaining to religion and the salvation of souls derived from its divine constitution rather than from delegation by the state (Pope Leo XIII 1885).

In the pre-conciliar Catholic understanding, the Church was not regarded merely as a religious association subject to the legal order of the state, but as a societas iuridice perfecta, possessing, by virtue of its divine foundation, the means and authority necessary to pursue its own ends. This conception was systematically elaborated by the Ius Publicum Ecclesiasticum school and was later presented in a particularly influential form by Alfredo Ottaviani. According to this approach, the Church constituted an autonomous legal order alongside the state, and its jurisdiction extended to matters intrinsically connected with its supernatural mission. In the case of marriage, this jurisdiction was understood as deriving not from a concession by secular authority but from the divine constitution and mission of the Church itself. Since marriage between baptized persons was regarded as a sacrament, the Church consequently claimed an original and autonomous competence over its sacramental and canonical regulation, while acknowledging the competence of the state with regard to its civil effects. The regulation of baptism and the religious upbringing of children likewise could not be regarded as falling exclusively within the competence of secular authority. From this perspective, the nineteenth-century controversies examined here reflected not merely resistance by the Catholic Church to state legislation, but a more fundamental conflict between two legal orders claiming jurisdiction over partly overlapping spheres of social life (Ottaviani 1935; Sipos 1960).

6. The Development of the System of Reversales in Hungary

Against this background, the Catholic Church in Hungary initially adopted the same strict prohibition of mixed marriages that prevailed elsewhere in the Catholic world. By the eighteenth century, however, this uncompromising position had gradually softened. Mixed marriages were still not encouraged by the Church and were permitted only for grave reasons, ad maius malum vitandum (“to avoid a greater evil”), and subject to specific conditions safeguarding Catholic doctrine. Among the most important of these conditions was the requirement that all children born of mixed marriages be raised in the Catholic faith. Had this requirement been consistently enforced, however, the proportion—and consequently the social and political influence—of Protestant and other non-Catholic denominations would inevitably have declined. Unsurprisingly, this condition provoked increasing resentment and eventually open opposition among non-Catholic communities (Giczi 2014).

The Hungarian Estates first attempted to regulate the issue at the Diet of 1790–1791, convened shortly after the death of Emperor Joseph II, whose ten-year reign had pursued a comparatively restrained policy towards the Catholic Church within the Habsburg Monarchy. Section 15 of Act XXVI of 1790–1791 provided that all mixed marriages had to be celebrated before a Catholic priest (Šoltés 2015). It further stipulated that, where the father was Catholic, the children were to be raised as Catholics, whereas if the mother was Catholic, the sons might follow the religion of their father. This latter provision, expressed in the original Latin by the permissive phrase sequi possint (“may follow”), rather than imposing a mandatory rule, became the source of most subsequent disputes. In practice, Catholic clergy increasingly required non-Catholic fathers to sign a written declaration—the so-called reversalis—undertaking that all children born of the marriage would be brought up in the Catholic faith (C. Herger 2010).

Although this practice was subsequently recognised by several royal decrees, Protestants protested against this interpretation of the law as early as 1793. The issue remained on the political agenda throughout the Reform Era. Protestant representatives repeatedly demanded the abolition of reversales during successive sessions of the Diet, most notably in 1832–1836 and again in 1839–1840. From the Protestant perspective, however, the controversy was not simply a dispute over the interpretation of individual provisions governing mixed marriages. The system of reversales was regarded as one manifestation of the unequal position of the Christian denominations in Hungary. Protestant opposition increasingly invoked the principles of freedom of conscience, confessional reciprocity, and legal equality. These principles were not understood merely as political demands: contemporary Reformed ecclesiastical bodies themselves presented freedom of conscience, full reciprocity, and equality before the law as rights belonging to Protestants under both divine and human law. The requirement of a reversalis, by contrast, placed the Protestant party—particularly a Protestant husband—in a position in which marriage to a Catholic woman could effectively be made conditional upon accepting the Catholic upbringing of their children. Protestant opposition therefore regarded the practice as incompatible with the equal legal status of the denominations and with the freedom of conscience of the parties concerned (Fazekas 2008).

At the same time, the Protestant position should not simply be identified with the liberal political programme. The controversy had originally emerged primarily as a Protestant religious grievance, but during the 1830s and especially the early 1840s it became increasingly connected with the broader liberal demand for the reorganization of church–state relations. Protestant denominational interests and liberal constitutional arguments therefore frequently coincided without being identical. This development helps to explain why the mixed-marriage controversy could evolve from a dispute between denominations into a wider political conflict concerning religious equality, freedom of conscience, and the respective authority of church and state (Fazekas 2008). Recognising the growing political willingness to address Protestant grievances, the Catholic hierarchy sought alternative solutions that would preserve the integrity of Catholic doctrine while avoiding an open confrontation with the legislature (Salacz 1938).

The immediate catalyst for the renewed controversy at the Diet of 1839–1840 was a pastoral letter issued by Bishop Ferenc Lajcsák of Nagyvárad (Oradea) on 15 March 1839, followed by detailed instructions published on 22 April of the same year. Lajcsák ordered his clergy to confer the nuptial blessing in mixed marriages only if the Protestant party provided a written guarantee that all future children would be raised as Catholics. In the absence of such a reversalis, priests were instructed to perform only passive assistance, that is, to witness the marriage without imparting the ecclesiastical blessing. In doing so, Lajcsák faithfully applied the prevailing principles of Catholic canon law. Liberal politicians and the county assemblies (comitates), however, regarded these measures as incompatible with Hungarian civil law and with the principle of confessional reciprocity (Šoltés 2015).

The first county to challenge the bishop’s regulations was Bihar County, where Nagyvárad itself was located. Its liberal position was represented in the Diet by Ödön Beöthy. Several other counties soon joined the protest. The most vocal among them was Gömör County, where Bishop János Scitovszky of Rozsnyó (Rožňava) pursued essentially the same policy as Lajcsák (Szuly 2025). Consequently, contemporaries referred to the parliamentary dispute as the “Nagyvárad–Rozsnyó controversy.” Eventually, the Lower and Upper Chambers reached a compromise. According to the proposed legislation, mixed marriages would be celebrated before the minister of the husband’s confession, while the children would follow the father’s religion. This solution largely reflected the position advocated by Protestant representatives and the liberal counties. King Ferdinand V, however, refused to grant royal assent, and the bill never entered into force. The rejection further intensified tensions between the liberal counties and the Catholic episcopate (Busku 2009).

Under these circumstances, the Hungarian bishops decided to seek guidance from the Holy See. Responsibility for the negotiations in Rome was entrusted to József Lonovics, Bishop of Csanád. The choice was deliberate. Although Lonovics firmly represented the Catholic position, he was also regarded as an able diplomat capable of reaching a practical compromise. His appointment was strongly supported by Prince Klemens von Metternich, the most influential statesman of the Habsburg Empire—King Ferdinand V’s mental incapacity severely limited the monarch’s personal involvement in government (Busku 2009).

Lonovics travelled to Rome in 1840 to negotiate directly with Pope Gregory XVI. After approximately eighteen months of discussions, the negotiations resulted in the issuance of the papal brief Quas vestro and the accompanying Lambruschini Instruction on 30 April 1841. While the Holy See maintained its traditional theological reservations concerning mixed marriages and continued to insist upon the Catholic upbringing of children, it formally accepted the practice of passive assistance. Furthermore, with regard to the dioceses of Hungary and Transylvania, it recognised the canonical validity of mixed marriages celebrated before Protestant ministers. Nevertheless, this compromise failed to resolve the Hungarian controversy. Liberal public opinion continued to demand the complete abolition of the reversales system, whereas the Catholic episcopate remained committed to the principle of ensuring the Catholic education of children (Bárány 2014).

From a canonical perspective, the settlement of 1841 should not be understood merely as a political compromise prompted by the Hungarian denominational conflict. The Quas vestro brief and, more specifically, the accompanying Lambruschini Instruction introduced an exceptional territorial solution for the lands of the Hungarian Crown. By declaring the Tridentine form non-binding for mixed marriages in this territory, the Instruction recognized the validity of such marriages even when they were contracted without Catholic canonical form, including those celebrated before a Protestant minister. In this respect, the settlement amounted to a territorial exemption from the application of Tametsi to mixed marriages in Hungary: although such marriages could remain prohibited and therefore illicit, failure to observe the Tridentine form did not render them invalid. The concession was therefore not merely pastoral or political, but constituted a significant modification of the canonical regime applicable to mixed marriages in Hungary. Gregory XVI continued to characterize marriages contracted without the prescribed guarantees as prohibited and illicit, but nevertheless permitted, where greater harm could not otherwise be avoided, the purely passive presence (passiva assistentia) of the Catholic parish priest. The priest was to perform no religious rite and to act only as a qualified witness, receiving the consent of the parties and recording the validity of the marriage. Thus, the brief preserved the Church’s doctrinal and canonical disapproval of mixed marriages while providing a juridical mechanism by which their validity could be recognized in the specific confessional circumstances of Hungary (Gregory XVI 1841).

The counties therefore renewed their campaign of protest. Even before Lonovics’s return, Borsod County had criticised his Roman mission, declaring it contrary to Hungarian law and urging other counties to adopt similar resolutions. Following the promulgation of Quas vestro, several counties protested against the royal placetum—the royal authorisation permitting the publication of the papal brief within Hungary. They interpreted this as an unacceptable intervention by a foreign ecclesiastical authority, namely the Roman Catholic Church, in Hungarian legislation and in what they regarded as a purely domestic matter. In the eyes of the liberal counties, papal intervention violated Hungarian constitutional autonomy, undermined the legislative authority of the Diet, and conflicted with the principle of confessional equality.

The controversy finally reached its conclusion during the Diet of 1843–1844. Act III of 1844 prohibited the requirement of reversales, recognised retrospectively the legal validity of mixed marriages celebrated before Protestant ministers, and substantially simplified the legal procedure for conversion to Protestantism. In legislative terms, the act represented a clear victory for the liberal reform movement and marked the first decisive limitation of Catholic ecclesiastical influence over the regulation of mixed marriages in Hungary (Šoltés 2015).

7. The Question of “Re-Baptisms” in the Hungarian Kulturkampf

The issue subsequently receded into the background for several decades. Until 1848, no major developments occurred. Following the defeat of the Hungarian War of Independence, however, Emperor Franz Joseph I introduced a neo-absolutist regime in Hungary, during which neither the Diet nor the county assemblies were permitted to function. With the gradual political liberalization beginning in the early 1860s, Hungarian political life revived, and the controversy resurfaced. This renewed conflict was fuelled by the continued resistance of much of the Catholic clergy, supported by the episcopate, to the legislation enacted by the Hungarian Diet. Catholic priests continued to require reversales in mixed marriages and frequently baptized children contrary to the provisions of civil law.

One of the earliest and most widely publicized incidents concerned Lajos Kossuth, the leading liberal politician of the Reform Era. In 1840, shortly after his release from prison, Kossuth, a Lutheran, sought to marry Terézia Meszlényi, a Roman Catholic. Because he refused to provide a reversalis, the Catholic clergy denied the couple the nuptial blessing, provoking a political scandal in Pest County. At approximately the same time, Miklós Thassy, the parish priest of Miskolc, publicly announced that, following a circular issued by the Archbishop of Eger, he too would refuse to bless mixed marriages unless the prescribed ecclesiastical conditions were fulfilled (Fazekas 2004a, 2004b).

An even greater controversy erupted in early 1841 through the actions of Ferenc Illyés, parish priest of Edelény. Illyés adopted an unusually literal interpretation of the practice of passive assistance. When a mixed-confessional couple insisted upon their legal right to marry without providing a reversalis, he refused to celebrate the marriage in the church before the assembled congregation. Instead, he instructed his cantor to witness the marriage in a small adjoining chamber while the wedding guests remained waiting inside the church. The incident quickly attracted national attention. Borsod County initiated an official investigation, and the county assembly transformed the affair into a major political issue. Liberal county leaders, among them László Palóczy, argued that the parish priest had violated Act XXVI of 1790–1791 by subordinating Hungarian law to papal directives. The controversy soon reached the Diet, while contemporary newspapers—including Pesti Hírlap, Világ, and Nemzeti Újság—reported on the affair extensively. Several administrative proceedings were initiated against Illyés, and at one stage criminal prosecution was also contemplated. His bishop, however, consistently defended him, maintaining that the priest had merely implemented the official regulations of the Catholic Church rather than acting on his own initiative (Fazekas 2002).

The restoration of Hungarian constitutional government following the Austro-Hungarian Compromise of 1867 prompted the newly re-established parliament to address the issue without delay. On the initiative of the Ministry of Religion and Public Education, headed by Baron József Eötvös, one of the leading liberal statesmen of the Reform Era, Act LIII of 1868 on Reciprocity among the Legally Recognized Christian Denominations was enacted the following year (Márkus 1896). In addition to reaffirming the principle of confessional equality proclaimed by Act XX of 1848, Section 12 provided that children born of mixed marriages were to follow the religion of their parents according to their sex: sons the religion of their father and daughters that of their mother. Despite this statutory regulation, the Catholic Church continued to seek the retention of children from mixed marriages within the Catholic faith. Consequently, the practical situation remained largely unchanged.

Protestant circles maintained that Section 53 of Act XL of 1879 on Minor Offences, which formed part of the first Hungarian Penal Code together with Act V of 1878 (the so-called Csemegi Code), applied directly to cases of so-called “re-baptisms.” The provision stated that anyone who admitted a minor under the age of eighteen into another religious denomination contrary to the provisions of Act LIII of 1868 could be punished by imprisonment of up to two months or a fine of up to three hundred forints. The courts, however, did not consistently share this interpretation.

As a result, Protestant ministers repeatedly initiated criminal proceedings against Catholic priests who had baptized children contrary to the statutory rules. The first final acquittal was delivered by the Budapest Court of Appeal on 29 December 1880 in proceedings against Endre Póda, Abbot-Parish Priest of Sopron, and one of his assistant priests. The court reasoned that baptism did not make the child a member of the Roman Catholic Church, but merely of the universal Christian community. Moreover, because the civil status registers clearly recorded both the religion of the parents and, consequently, the child’s legally determined denomination, the administration of baptism itself could not constitute a violation of Section 53 of Act XL of 1879. Criminal proceedings nevertheless continued. The decisive turning point came on 24 March 1882, when the Royal Curia, Hungary’s supreme judicial authority, delivered a landmark judgment in the case of a curate from Tata accused of “re-baptizing” two children. The Curia held that Section 53 of Act XL of 1879 was intended to provide criminal sanctions only for violations of Section 2 of Act LIII of 1868, which regulated conversion, and not of Section 12 governing the religious affiliation of children. Since infants were legally incapable of changing their religion, a priest accused merely of baptizing them contrary to the statutory allocation of denomination could not be convicted under the penal provision (Salacz 1938).

Almost two decades after the enactment of the 1868 legislation, Ágoston Trefort, Minister of Religion and Public Education—and himself a member of the liberal political generation of 1848—attempted to resolve the continuing controversy by administrative means. In 1884 he issued Decree No. 24,727 on the Mutual Transmission of Baptismal Certificates of Children Born of Mixed Marriages. After reaffirming the intentions underlying Act LIII of 1868, the decree declared reversales and similar undertakings to be legally void. It further provided that if a minister nevertheless baptized a child contrary to the statutory rules, the baptism could not be entered into his own parish register, and all baptismal documents had to be forwarded without delay to the minister legally responsible for maintaining the child’s official ecclesiastical records (Rada 2024).

Because the decree contained no effective sanctions, however, it proved largely ineffective. Consequently, in February 1890 Albin Csáky, Trefort’s successor as Minister of Religion and Public Education, issued a new decree specifically directed against “re-baptisms.” Under this regulation, refusal to transfer the baptismal certificate constituted a statutory offence punishable by a fine of between five and ten forints, while repeat offenders could be fined up to one hundred forints. Since parish priests normally celebrated numerous mixed marriages, the higher penalty soon became the norm. The authorities immediately began imposing fines on a large scale.

The refusal of Catholic priests to surrender baptismal records should also be understood against the background of the Catholic conception of ecclesial membership. Baptism was understood as establishing a permanent sacramental bond with the Church, a conception later expressed in canonical terminology by the maxim semel catholicus, semper catholicus (“once a Catholic, always a Catholic”). Consequently, from the ecclesiastical perspective, a person’s subsequent adherence to another denomination did not simply erase the canonical significance of his or her Catholic baptism. The refusal to facilitate the transfer of baptismal documentation could therefore be perceived by the clergy not merely as resistance to secular legislation, but as an obligation arising from their understanding of the continuing ecclesiastical status of the baptized person. This helps to explain why compliance with state regulations concerning denominational change could appear to Catholic priests as conflicting with their ecclesiastical duties (Petrat 2018).

Two cases attracted particular public attention. In Komárom, Gábor Papp, Bishop of the Reformed Church, filed criminal charges against János Molnár, the local Catholic abbot-parish priest, for unlawfully baptizing a child belonging to another denomination. In Gyoma, when Gyula Spett, the Catholic parish priest, refused to issue the baptismal certificate of a child who had been “re-baptized,” a state bailiff intervened and entered the fact of the baptism into the Protestant parish register on his own authority. These incidents became symbols of the increasingly bitter confrontation between the Catholic Church and the liberal Hungarian state during the closing phase of the Hungarian Kulturkampf (Fazekas 2008).

8. The Resolution of the Controversy and Its Impact on Ecclesiastical Autonomy

In response to the escalating conflict, the Hungarian Catholic episcopate appealed to the Holy See. As a result, on 26 September 1890, Cardinal Mariano Rampolla del Tindaro, Secretary of State to Pope Leo XIII, addressed a letter to János Simor, Archbishop of Esztergom and Primate of Hungary. This document proved to be of decisive importance, as it declared that a Catholic priest could not participate in any procedure that might create the appearance that a child did not belong to the Catholic Church. The Holy See also condemned the earlier practice adopted by certain bishops who, propter bonum pacis (“for the sake of peace”), had transferred baptismal certificates to Protestant ministers. From that point onward, the Vatican no longer regarded the matter as a merely administrative question but as one involving fundamental principles of faith.

At the same time, the papal position did not seek to perpetuate open confrontation but rather aimed at achieving a practical compromise. The Hungarian episcopate therefore entered into negotiations with the government, while Emperor and King Franz Joseph I was equally determined to prevent the religious dispute from developing into a constitutional crisis. Acting as mediator between the Hungarian government and the Holy See, the monarch sought a solution that would preserve the authority of the state without compelling the Catholic Church to act contrary to its own doctrinal principles.

These negotiations resulted in the emergence of a modus vivendi, a practical compromise between the two sides. Under this arrangement, Catholic priests could continue to baptize children and record the baptism in their own parish registers. At the same time, however, they were required, in accordance with state law, to transmit the baptismal certificate to the minister of the denomination to which the child legally belonged under Act LIII of 1868. The Catholic Church interpreted this requirement not as implying that the child ceased to be Catholic, but merely as compliance with an administrative obligation imposed by the state. This solution enabled Catholic clergy, acting according to their conscience, to continue administering the sacrament of baptism while simultaneously allowing the state to enforce its regulations governing official registration. Nevertheless, the compromise was not universally accepted. Several bishops and parish priests continued to refuse to transfer baptismal certificates, with the result that the imposition of administrative fines continued (Salacz 1938).

The modus vivendi, however, represented only a partial settlement. Protestant churches continued to regard it as inadequate because, in their view, it failed fully to enforce the provisions of Act LIII of 1868, whereas the Catholic hierarchy maintained that the state continued to interfere in matters falling within ecclesiastical jurisdiction. The underlying conflict therefore remained unresolved; it had merely been temporarily mitigated (Salacz 1938).

Moreover, the confrontation between the liberal political elite and the Catholic Church extended well beyond the issue of “re-baptisms.” It formed part of the broader Hungarian Kulturkampf, encompassing disputes over marriage, civil registration, and the elimination of legal distinctions between religious denominations. The final settlement was achieved not through the compromise between the Holy See and the monarch, but through the comprehensive ecclesiastical policy legislation enacted in 1894–1895. Act XXXI of 1894 introduced compulsory civil marriage, while Act XXXIII of 1894 established a system of state civil registration. Marriage and the official registration of births thereby ceased to fall within the exclusive competence of the churches, rendering many of the legal disputes surrounding baptism effectively obsolete. Although questions of confessional affiliation did not disappear, the introduction of civil registration eliminated the legal conflict that had previously centred on ecclesiastical baptismal registers. As Salacz observed, the ultimate consequence of the Kulturkampf initiated by the Csáky Decree was the establishment in Hungary of a modern civil system of marriage and registration (Nagy 2025).

The issue of children’s religious affiliation was finally re-regulated by Act XXXII of 1894. From the perspective of confessional autonomy, the new legislation represented a significant innovation. Section 1 provided that couples belonging to different legally recognised or officially acknowledged denominations could, before contracting marriage, agree once and for all that all of their future children should follow either the religion of the father or that of the mother. This provision effectively resolved the central issue that had dominated confessional controversy for more than a quarter of a century. In order to prevent future disputes concerning the existence or validity of such agreements, however, the law subjected them to strict formal requirements. They were valid only if concluded before a royal notary public, a district judge, a mayor, or a chief district administrator. Consequently, although the legislation considerably expanded the autonomy of the churches and of the spouses themselves, it did not entirely remove the matter from the sphere of state jurisdiction. For this reason, the new regulation continued to attract criticism from Catholic circles, which regarded the remaining state involvement in matters of religious affiliation as an infringement of ecclesiastical autonomy (Nagy 2025).

9. Conclusions

At first sight, the enactment of the Hungarian ecclesiastical policy legislation of 1894–1895 appeared to bring both the secularization debates and the controversy over so-called “re-baptisms” to an end. In reality, however, the tensions did not entirely disappear, because the conflict extended far beyond the question of the religious affiliation of children. Secularization has traditionally been understood as the gradual reduction in ecclesiastical influence over state affairs. Contemporary theories of secularization, however, emphasize that the separation of church and state is inherently a two-sided process. While the state progressively emancipates itself from ecclesiastical jurisdiction, it simultaneously claims increasing authority to define the legal framework within which religious life is conducted. The controversy over “re-baptisms” illustrates this process particularly well. The Hungarian state sought not merely to protect its own sphere of competence against ecclesiastical interference but also to regulate by statute the confessional affiliation of children, the legal consequences of baptism, and the administration of ecclesiastical registers. The conflict therefore concerned not simply the separation of church and state but also the extent to which a modern state may legitimately determine the legal framework of matters that are fundamentally religious in nature. In this respect, the Hungarian ecclesiastical policy struggles of the late nineteenth century exemplify the process described by José Casanova as the differentiation of social functions (Casanova 1994) and by Charles Taylor and Talal Asad as the state’s reconfiguration of the religious sphere (Asad 2003; Taylor 2007).

At the same time, the controversy over “re-baptisms” cannot be understood solely through the political developments of the Dualist period. Its roots extend back to the Hungarian Reformation. The emergence of a permanently multi-confessional society during the sixteenth and seventeenth centuries, together with the consolidation of Catholic canon law during the Catholic Reformation, created the religious environment in which mixed marriages became a matter of exceptional importance. The confessional affiliation of children was far more than an issue of family law; it directly influenced the demographic strength, institutional continuity, and long-term social position of the individual denominations. Consequently, both Catholics and Protestants regarded the issue as one affecting the future of their respective religious communities.

So long as ecclesiastical rules continued to produce legal effects in the secular sphere, such concerns were, at least in part, understandable. If, for example, ecclesiastical law prohibited divorce for some citizens while permitting it for others, and no alternative legal mechanism existed through which equality before the law could be achieved, there were persuasive arguments for state intervention in matters traditionally regulated by the churches. Yet the very success of secularization fundamentally altered this relationship. As the civil legal consequences of ecclesiastical norms were progressively eliminated, state intervention in internal religious affairs itself began to raise new questions concerning the proper limits of secularization.

This tension became immediately apparent during the parliamentary debates on the ecclesiastical policy legislation. One illustrative example concerned the formal requirements governing parental agreements on the future religious affiliation of children. Baron Károly Hornig, Bishop of Veszprém, proposed that such agreements should also be valid if concluded before the couple’s parish priest in the presence of witnesses. The response of Baron Loránd Eötvös, Minister of Religion and Public Education, is particularly revealing from the perspective of this study. He rejected what appeared to be only a minor amendment on the grounds that the very purpose of the ecclesiastical policy legislation was to establish a clear institutional separation between church and state, ensuring that their respective competences would no longer overlap. His reasoning, however, was not entirely symmetrical. Eötvös argued that the state nevertheless had a legitimate interest in supervising the confessional affiliation of children because this information remained relevant for the organization of religious education in schools. (Although he referred specifically to religious instruction, it should also be recalled that primary education in nineteenth-century Hungary was itself still largely administered by the churches.) Dezső Szilágyi, Minister of Justice, further supported this position by arguing that Hornig’s proposal would fail to eliminate long-standing Protestant complaints that Catholic parish priests had frequently abused their local authority to prevent children from being baptized into other denominations (Országgyűlés 1895).

The controversy was therefore simultaneously theological and juridical in nature: theological convictions concerning the sacramental nature of marriage, baptism, the religious unity of the family, and the Church’s responsibility for the salvation of children acquired political significance precisely because they were embedded in two distinct and partly competing legal orders. The Catholic episcopate regarded the universal canon law of the Church as the supreme normative authority in matters falling within ecclesiastical jurisdiction, whereas the liberal political elite proceeded from the legislative sovereignty of the Hungarian state. The disputes over reversales during the Reform Era, József Lonovics’s diplomatic mission to Rome, the papal brief Quas vestro, the subsequent litigation concerning “re-baptisms,” and finally the controversy surrounding the Csáky Decree all emerged from this fundamental conflict between ecclesiastical and civil jurisdiction.

It is equally noteworthy that the controversy ultimately concluded without the complete victory of either side. The state successfully removed marriage and civil registration from the exclusive jurisdiction of the churches, while the Catholic Church preserved the integrity of its own internal legal order. Consequently, the ecclesiastical policy legislation of 1894–1895 did not abolish the Catholic theological doctrine concerning mixed marriages; it merely deprived that doctrine of its civil legal consequences. What had previously been a conflict between church and state gradually evolved into an internal question of canon law and pastoral practice. The final transformation of Catholic teaching occurred only with the ecumenical orientation of the Second Vatican Council and the subsequent reforms of canon law.

The Hungarian controversy over “re-baptisms” should therefore also be understood within a broader European context. It was closely connected with the Prussian disputes over mixed marriages, the Holy See’s nineteenth-century matrimonial policy, and the wider Kulturkampf conflicts that unfolded across much of continental Europe. At the same time, the Hungarian case possessed distinctive national characteristics. Questions of confessional affiliation became closely intertwined with constitutionalism, national sovereignty, and, later, the construction of the modern civil state. This explains why the disputes surrounding reversales and later “re-baptisms” remained recurring issues in Hungarian political life for more than half a century.

Ultimately, the history of the “re-baptism” controversy demonstrates that the modern understanding of religious freedom and state–church relations was not the product of a single legislative act but the outcome of a long process of historical development. Nineteenth-century Hungarian legislation did not seek to eliminate the social significance of religion. Rather, it aimed to establish a legal framework within which religious communities could function while safeguarding both equality before the law and the sovereignty of the state. The controversy over “re-baptisms” should therefore be understood not merely as a denominational dispute but as one of the most instructive chapters in the constitutional development of the modern Hungarian state and in the broader European history of the relationship between church and state.
