Conciliarism

• 1. Origins And Western Schism

  ›

  The year 1378 marked the beginning of a crisis that fractured the Catholic Church. Two men claimed to be the true pope, one residing in Rome and the other in Avignon. This division became known as the Western Schism. Rival popes excommunicated each other while their supporters chose sides based on political loyalty rather than spiritual conviction. The chaos created a desperate need for a solution beyond the existing hierarchy. Government leaders began urging both claimants to step down so a new election could take place. This pressure led to the summoning of the Council of Pisa in 1409. The council failed to end the schism and instead added a third claimant to the mix. The situation grew more complex with every attempt at resolution. The Council of Constance convened between 1414 and 1418 to finally resolve the dispute. It succeeded in ending the schism but also declared its own authority superior to that of the Pope.

• 2. Theoretical Foundations

  ›

  Marsilius of Padua published Defensor Pacis in 1324 to challenge traditional church structure. He argued that the universal Church belongs to the faithful, not just the priests. Marsilius insisted that Jesus alone is the head of the Catholic Church. His work suggested that priestly inequality has no divine basis. William of Ockham wrote early documents outlining conciliarist ideas before his death in 1349. Ockham sought to remove Pope John XXII who had revoked a decree favoring Spiritual Franciscans. He claimed that elections by the faithful confer papal position and limit papal power. Conrad of Gelnhausen emerged as a founder of the late fourteenth century movement. He advocated for an autonomous General Council to settle the Western Schism of 1378. Henry of Langenstein echoed this call for council-based solutions. Jean Gerson, Pierre d'Ailly, and Francesco Zabarella developed more conservative clerical versions of these theories. Nicholas of Cusa later synthesized hierarchy with consent and representation of the faithful.

• 3. Major Councils And Conflicts

  ›

  The Council of Pisa convened in 1409 but failed to resolve the papal dispute. It produced three claimants instead of one unified leader. The Council of Constance ran from 1414 to 1418 and achieved greater success. This assembly proclaimed its own superiority over the Pope while ending the schism. The Council of Basel operated between 1431 and 1449 during the movement's peak years. These councils represented attempts to place supreme authority within ecumenical gatherings rather than individual pontiffs. Each meeting tested the limits of papal power against collective ecclesiastical decision-making. The eventual victor remained the pope and the institution of the papacy itself. The Fifth Lateran Council ran from 1512 to 1517 and confirmed papal teaching authority through condemnation of conciliarism. This outcome marked a turning point where institutional power reasserted dominance over reformist movements.

• 4. Papal Opposition And Defeat

  ›

  Juan de Torquemada defended papal supremacy in his Summa de ecclesia completed around 1453. He argued that Peter alone held the vicariate of Jesus Christ with immediate jurisdiction from Christ. Thomas Cajetan wrote On the comparison of the authority of pope and council a generation later. Cajetan stated that Christ gave full ecclesiastical power not to the community but to a single person. Pope Pius II insisted that doctrines holding General Councils superior to the Pope were heretical. His bull Execrabilis formally condemned conciliarist principles. Pope Pius VII issued another condemnation on the 3rd of June 1816 targeting Germanos Adam's writings. These actions represented systematic theological counter-arguments developed by church leaders. The doctrine of papal infallibility adopted by the First Vatican Council in 1870 reached the apex of papal authority theory. This development ironically occurred after centuries of conciliar challenges had been suppressed.

• 5. Modern Revival And Legacy

  ›

  Conciliar strains of thought remain within the Church despite official teachings maintaining papal supremacy. Professor David D'Avray notes that Second Vatican Council documents emphasize episcopal authority as conjoined with papal power rather than over it. A new interest in conciliarism emerged following the convocation of the Second Vatican Council. Contemporary Catholic theology continues to engage with these historical debates about governance structures. The movement left an enduring legacy through its influence on Gallicanism in France according to John Kilcullen. Modern scholars examine how conciliar ideas shaped discussions about church reform and representation. The tension between hierarchical authority and collective decision-making persists in current ecclesiastical discourse. Historical records show that while the movement lost political battles, its theoretical contributions remain relevant to ongoing theological conversations.
