What is Conciliarism? Definition and Key Concepts Conciliarism is a viewpoint that places ultimate ecclesiastical authority in a collective gathering—or council—of church leaders, rather than in any single individual office. In its classical form, it asserts that an ecumenical council convened by church leaders holds the power to adjudicate doctrinal disputes, discipline leaders, and serve as the highest authority in matters of faith and practice. Historically, this perspective emerged most prominently in the late Middle Ages, seeking to resolve church schisms and asserting that, under certain conditions, a council of bishops could even depose a pope. Conciliarism is distinguished from other church governance models that vest supreme authority in a single bishop—most famously, the Bishop of Rome (the pope), according to the Roman Catholic tradition. Proponents of conciliarism lean on the idea that conciliar decrees, when properly grounded in Scripture, creed, and historic church tradition, form the most authoritative guide for the universal church. Critics, on the other hand, question whether such councils have the jurisdiction or scriptural backing to stand above an established ecclesial office. Historical Background Conciliarism did not simply appear at a single moment in history. Its roots can be traced to the early centuries, when regional synods and ecumenical councils—such as the Councils of Nicaea (AD 325) and Chalcedon (AD 451)—undertook the vital work of clarifying Christian doctrine. During these councils, bishops from across the known world sought unity on central truths of the faith, including the nature of Christ, the Trinity, and the core creeds. However, conciliarism as a well-developed theory arose most notably during the 14th and 15th centuries. One of the driving catalysts was the Western Schism (1378–1417), when multiple individuals claimed the papal throne simultaneously, leaving Europe divided on which pope to follow. Desiring a conclusive solution, leading church figures convened the Council of Pisa (1409), which attempted to end the schism but ultimately produced a third claimant to the papacy. The Council of Constance (1414–1418) then convened, famously condemning and executing Jan Hus for alleged heresy, deposing rival popes, and restoring a single pope. The council also laid down statements interpreting conciliar authority as binding, effectively asserting a council’s power to sit in judgment upon a reigning pope if circumstances required it. Although the Council of Constance is considered the apex of conciliarism in practice, the theory continued to influence ecclesiastical politics. Disputes over authority, however, did not find a final resolution, especially after the popes eventually reasserted their rulings, culminating in the Fifth Lateran Council (1512–1517) and later the Council of Trent (1545–1563), which solidified the supremacy of the papacy in the Roman Catholic hierarchy. Conciliarism and the Early Church Councils Ancient precedents for church councils exist throughout early Christian history. The first example is typically cited from Acts 15, commonly referred to as the Jerusalem Council, where church leaders convened to address the question of Gentile believers and adherence to Mosaic Law. Scripture records: • “It seemed good to the Holy Spirit and to us not to burden you with anything beyond these essential requirements…” (Acts 15:28). This council provided a biblical model for corporate discernment, adhering to what was understood to be the guidance of the Holy Spirit while accommodating church unity. Beyond the earliest gatherings, subsequent councils grew in significance, with bishops assembling to address critical doctrinal matters such as the Arian controversy (Council of Nicaea, AD 325) and Christological definitions (Council of Chalcedon, AD 451). Proponents of conciliarism draw parallels between these authoritative councils and their view that such gatherings are the proper mechanism to settle matters of church doctrine and governance. Key Developments in the Late Middle Ages During the late Middle Ages, the schisms and political turmoil within the Western Church fostered a climate wherein conciliarism thrived. Key factors included: 1. Multiple Papal Claimants – The simultaneous existence of two or three popes led many theologians to conclude that a higher, collective authority must resolve the chaos. 2. Texts and Canon Law – Certain church canons and writings (e.g., those attributed to early councils or prominent bishops) were interpreted to endorse the idea that the universal church, represented by bishops in council, held supreme authority. 3. Reform Movements – The desire for moral and doctrinal reform led some to believe that a council was more impartial and responsive to widespread concerns than a single papal office might be. Conciliarism gained its most official recognition at the Council of Constance, which exercised powers of deposition and election. Yet, once the crisis of the Western Schism ended, the papacy regained stronger control. Resistance to ongoing conciliar claims continued, and conciliarism as an official theory lost some of its influence after the papacy reasserted its primacy. Scriptural Considerations Within Scripture, local and regional councils—particularly those formed by apostles and elders—appear to carry significant weight (Acts 15). Proponents of conciliarism often point to these passages to argue for a collegial or egalitarian framework for decision-making, emphasizing community discernment guided by the Holy Spirit. Conversely, others point to additional teaching about spiritual leadership, acknowledging that different church offices fulfill distinct roles within the body of believers (cf. Ephesians 4:11–12). While Scripture shows examples of collaborative leadership, it also depicts certain individuals—like Paul or Peter—who exercised substantial authority and responsibility. The question becomes whether final authority resides in a single office, in a council, or (ultimately) in divine revelation as preserved in Scripture. Controversies and Challenges 1. Authority of Scripture vs. Council Some argue that the final arbiter in church matters should be Scripture. When a council’s ruling appears to contradict biblical teaching, adherents to a strict scriptural authority posit that the Council’s authority must yield to the revealed word of God. 2. Role of the Papacy In traditions that stress the papal office, the pope is viewed as the visible head of the church, the successor of the apostle Peter, and often regarded (in Roman Catholic theology) as divinely guided, especially when making ex cathedra statements. Conciliarism directly challenges such a view by granting a council collective supremacy, which leads to an inherent tension. 3. Unity Versus Fragmentation Conciliarism raises questions about unity: do multiple centers of authority lead to greater cohesion, or can it potentially spur fragmentation if councils disagree with each other or a central figure? Modern Relevance While the height of conciliarism diminished after the 15th century, its themes still resonate in some church contexts where synods and councils play a formal role in governance. Discussions about accountability, mutual discernment, and checks on papal or episcopal power evoke conciliarist concepts. In broader circles, the interplay between collective decision-making and top-down authority remains a conversation not only in church structures but also in other organizational models around the world. Historical examples—including the large-scale councils of the late medieval period—show the possibilities and pitfalls of anchoring authority in large ecclesiastical gatherings. Conclusion Conciliarism is a historical and theological viewpoint that holds a council of church leaders to be the highest authority in matters of faith and church governance, at times even above the papacy. It grew from genuine attempts to maintain unity and doctrinal integrity, particularly in times of crisis such as the Western Schism. Scriptural examples of councils (Acts 15) offer a biblical precedent for shared decision-making, but debate persists over the ultimate seat of authority within the church. Whether examined for its historical influence or its theological assertions, conciliarism continues to shape discussions on how Christians discern truth, address controversy, and exercise leadership in the global church. The tension it highlights—between corporate consensus and more centralized forms of authority—remains a significant aspect of ecclesiastical history and ongoing governance debates. Ultimately, for many believers, Scripture remains the supreme rule of faith, providing the framework within which any council or ecclesial authority must undertake its discernment. |
