In the eyes of many across Western Europe, the year 1378 marked the onset of an “execrable plague.” Poets and theologians spoke of a “contagious plant,” a “cruel beast, laying waste, consuming and destroying everything.”[1] Such apocryphal imagery[2] was commonly used in reference to the Black Death that had swept the continent mid century. In this case, however, the subject was a man-made one: a politically charged dispute that split the Catholic Church along nationalistic lines and permanently reduced the spiritual and moral prestige of the papacy. The Great Western Schism, as it came to be known, was the natural result of growing tension between French and Italian segments of the Church following the Avignon Papacy. The crisis directly resulted from a double pontifical election, but its seeds were buried much deeper. As Louis Salembier writes in his Catholic history of the conflict published in 1907, “All the past trials of the Church appear to revive, all her future crises exist in embryo in this unfortunate schism.”[3]
Above all, the Great Schism marked the beginning of the end for a unified Christendom. Scholars have argued that during the Middle Ages, “Europe was a factious family of nation-states, not a harmonious corpus Christianum.”[4] Nevertheless, the dream of a common mystic tradition, of a powerful Church wielding temporal and spiritual authority from Rome, was deeply entrenched in the popular imagination of the age. This is undoubtedly evidenced by the Christian elements of period literature, such as the bawdy tales of clerical indiscretion in Boccaccio’s Decameron and Chaucer’s Canterbury Tales, or the more elevated presentation of redemption in Dante’s Paradiso. In addition, the societal implications of authentic Christendom were specifically enunciated in Boniface VIII’s 1302 papal bull Unam Sanctam.
Though arguably extreme in tone, Boniface’s decree that “it is altogether necessary for salvation for every human creature to be subject to the Roman Pontiff”[5] did not propose anything revolutionary. It was simply a statement of the Church’s temporal power and a reassertion that membership within the body of Christ was necessary for deliverance. Clement V would later send a letter to Philip IV of France that clarified this very point: “And we do not wish that through this declaration, the aforesaid king, kingdom and its inhabitants be more subject to the Roman Church than they had been before,”[6] he writes. Still, Unam Sanctam was universally seen as a power grab. For Catholics, the great tragedy of the 13th and 14th centuries was that in failing to recognize the changing tides of the age, in attempting to incorporate emergent secular society into an authentic utopian Christendom, pontiffs eventually became embroiled in the same temporal partisanship that they hoped to circumvent.
It was in bringing a number of these latent problems to public attention that the Great Schism paved the way for democratization. Democratization came in the form of both conciliar theory and Gallicanism, the idea that French civil authorities had control over the Catholic Church within their own nation. The Church had always been political; its long history of temporal meddling proves that much. However, the usurpation of papal authority at Pisa and Constance seemed to foreshadow the rise of a democratic “priesthood of all believers” during the Reformation. Rome ultimately retained its ecclesiastical supremacy, but the Great Schism forever shattered the romantic, though decidedly unorthodox[7], view of popes as unblemished rulers with a license to do as they wished. The Church’s pragmatic solution to the split actually had much in common with the Machiavellian ideals of the Renaissance.
Before the Great Schism and Avignon Papacy, however, Rome’s power was unquestioned. In a sense, the fickle subjects of Rome had replaced the Jews as God’s chosen people in proudly Christian Europe. For some, then, French domination of the Church during the Avignon Papacy undermined its claim to catholicity. “In quitting Rome, their cradle, in separating themselves from the scared sepulcher of the Prince of the Apostles, in ceasing to reign over the land which had been hallowed with the blood of martyrs, the Popes seemed to hold cheap the support they received from memories so august,”[8] writes Salembier. Accordingly, Gregory XI’s return to the Eternal City at the urging of Catherine of Siena initially seemed to indicate good times ahead. Despite the long of history of intrigue, nepotism and scandal in the Papal States, a pope grounded in Rome was a much more legitimate successor to Peter than one controlled by the House of Valois in Avignon.

Pope Urban VI
When Gregory died in March 1378, fear of a papal return to France struck the general populace in Rome. As the conclave of sixteen cardinals deliberated, mobs roamed the streets outside and even invaded the Vatican, demanding the election of an Italian. The cardinals acquiesced, unanimously electing Bartolomeo Prignano on April 8. Formally, all seemed to be in order, but the cardinals soon realized that they had made a horrendous mistake. The new Urban VI, previously lauded for his prudence, proved to be an awful ruler. He displayed contempt for just about everyone, and publicly upbraided the very cardinals who had supported him. Many believed that Urban had gone mad and was unable to deal with the great temptations of his office. It was not long before the exasperated electors reconvened at Fondi and elected Clement VII as a suitable alternative.
The swift escalation of the schism left Catholics searching for answers. According to Philip Hughes, both papal lines had equally prestigious supporters, including doctors of Canon Law and an equal number of miracle workers. While Vincent Ferrer supported the Avignon popes throughout most of his life, others like Catherine of Siena and the visionary Constance de Rabastens supported the Roman pontiff. Initially, dialogue was strained to say the least. In a letter to the French cardinals, Catherine had only harsh criticism: “I tell you, you have done ill, you and the anti-pope, and I repeat that it is a member of the devil who has been elected. Had Clement been a member of Christ, he would have rather died than have consented to so great an evil, because like us he knows the truth, and cannot plead ignorance as an excuse.”[9] While such appeals to spirituality and virtue were noble, papal control over benefices and clerical taxes had created a situation in which a pope’s national affiliation was increasingly relevant. The schism was thus along national lines, with France, Spain and Scotland supporting the Avignon popes, while England, northern Italy, the Holy Roman Empire and most regions in northeastern Europe pledged allegiance to the Roman popes.
Faced with the prospect of a permanent split, lay theologians, ambassadors and a multitude of clergy assembled for a General Council at Pisa in 1409. Philip Hughes notes that the discussion had heretofore focused not only on practical means of ending the schism, but also on the philosophical questions it raised. Did bishops, for example, have the right to convene a council in the absence of an authoritative pope? Initially, Jean Gerson had argued that the cardinals could resort to epikeia, interpreting the legal language of papal supremacy according to intent rather than by the letter. Though radical, the scholar’s position was not beyond philosophical rationalization. Today, for instance, some vernacular translations of the Roman Missal utilize a related hermeneutic approach called dynamic equivalency.[10] However, Gerson had also suggested that theological justification for a summons was unnecessary given the desperate circumstances! Like William of Ockham and in stark opposition to Aquinas, he believed that theology and revelation ought to remain independent of man-made philosophical concepts. Gerson was a deep thinker, but one who valued the spirit and preservation of Christianity more than its hierarchical structure. As John Morrall writes, “it seems most plausible to suppose that his actions were guided not by any carefully–sought theory of ecclesiology, but by the living exigencies of his practical work as teacher and director of souls…he felt keenly the mischief wrought by the Schism upon the prospects of individual salvation and was determined to end it by the most practical means…one is tempted to say that, for Gerson, the peace and unity of the Church justify all means toward their achievement.”[11]
Thus, the decision to convoke the Council of Pisa was essentially a pragmatic one. Despite its revolutionary and inclusive nature, however, the grand synod ultimately failed to end the crisis. Both rival pontiffs, who still controlled large factions within the Church, had been immediately deposed, excommunicated, and replaced with the newly elected Alexander V. Nevertheless, Alexander’s reign was short-lived; he died in the spring of 1410 and was succeeded by Baldassare Cossa, John XXIII, whose inexperience and questionable morals only made things worse. John’s blatant nepotism was readily apparent, and his support dwindled quickly. It was not long before he agreed to abdicate. At the demand of Holy Roman Emperor Sigismund, he begrudgingly called another General Council to be held at Constance in the fall of 1414. As at Pisa, the council was to be open to scholars and representatives of the various Estates of Christendom. This time, however, the council would be organized by nation, with each delegation possessing one vote on crucial issues.
Years earlier, Henry of Lagenstein had written that, “When schisms continue, new heresies arise.”[12] The social turmoil of the schism had clearly led to a breakdown of doctrinal communion and split Christendom along secular lines. As one historian remarked about the council, “It is verily a tower of Babel. At Constance, as many different tongues are spoken, as many contradictory opinions are shown, as there are representatives of various nations to be met with,” Both Pisa and Constance addressed reform and heresy within the Church itself, but the gravity of the crisis at hand made these issues secondary. Complete reunification was instead the most important goal. Thus, while the Council of Constance condemned John Huss as a heretic, it ironically seemed to adopt his view that “the true Pontiff was Jesus Christ alone.”[13] The conciliar theory that soon evolved was attractive because it was feasible; it seemed to be the only way of fixing an impossible situation.

Council of Constance
And indeed, the situation did become quite desperate; Reading the writing on the wall, John fled Constance under cover of darkness in March of 1415 in hopes of provoking chaos and undermining the council’s legitimacy. His rash actions, intended to assert influence, quickly backfired. In a fervor of antipapal sentiment, Sigismund brought the disorganized council under control and passed the Sacrosancta decree, overturning centuries of Church tradition. Sacrosancta affirmed that an ecumenical council of the Church is superior in authority to any pope and that, “lawfully assembled in the Holy Sprit… it holds power directly from Christ.”[14] In addition, the Council established the Frequens rule, which stipulated that future pontiffs would be required to convene councils at regular intervals. It was not long before the French cardinals abandoned Benedict, the Avignon pope, and joined the emerging Church hierarchy of believers. Gregory XII of the Roman line resigned, although not before officially establishing the legitimacy of the council, though he refused to support its findings on supremacy. The council would elect a new pope, but his position as the supreme head of Christendom had been directly called into question. Gone were the days of Unam Snactam; The Vicar of Christ, the moral and spiritual shepherd of the flock, had transformed into an administrative figurehead limited by the partisan theological interpretations of competing nation states.
On November 11, 1417, amidst the pious chanting of hymns, Pope Martin V was elected by a conclave of cardinals and representatives from the five great nations. The Great Schism had essentially ended, though the controversy was by no means over. In the following years, reformers riding on the wave of conciliar success repeatedly attacked the institution of the papacy. The popes fought back, hoping to reconcile conciliar theory with their own belief in the primacy of Peter’s chair. Martin, following Frequens, did call a council at Pavia in 1423, but it was rather badly attended and he used this fact as a rationale for dissolving it. Eugenius IV, his successor, dutifully presided over the Council of Basel, but never approved any canons upholding the power of an ecumenical council over the pope.
Eventually, the Magisterium of the Church would reject conciliar theory at the Fifth Lateran Council, reverting back to the orthodox understanding of Rome and upholding the view of the pope as the visible representation of Christ on earth. Regardless, the damage had been done. According to Salembier, “the germs of opposition sown at Constance and Basle increased and turned kings and peoples aside from accepting reforms favorably, when their initiative was found in Roman authority.”[15] Writes Hughes, “The theologian will find it an easy matter to explain exactly how far this council, with its forty-six sessions, is truly a General Council lawfully summoned in the Holy Spirit, with a real claim to have been divinely guided in its acts. But at the time it dispersed, its prestige, immense and unquestioned, covered (for the ordinary man) all the council had enacted.”[16]
It is said that in politics, perception is reality. And indeed, the Great Schism certainly changed popular perception of Rome. In his commentary on Simon de Cramaud and Gallicanism, Howard Kaminsky writes that, “if Europe’s powers responded to the events of 1378 by choosing sides, thereby making the Schism great, it was not because the case for either contender was so overwhelming as to compel adherence. The Schism was created by acts of the will, a will to pursue one’s own interests and sympathies even though doing so meant destroying the unity of the church.”[17] To scholars, it is clear that Clement VII had gained authority simply because he was supported by the French monarchy. Accordingly, the people of the day began to see the Church as corrupted by politics, marked by the “odour of hell” rather than a “paradise of virtue.” [18] They blamed the failure of the Church on the machinations of its leaders and thus lost hope in the sanctity of the institution itself.
Some have argued that the Great Schism actually proved the papacy’s strength and divine right to command the faithful. Le Maistre suggested that, “It proves that St. Peter’s throne is unshakeable, for what human institution could survive such a trial?”[19] Still, the popular hope in the organized Church as the vehicle of salvation had been shattered. The papacy would continue to exert influence in secular affairs; Alexander VI negotiated the controversial Treaty of Tordesillas in 1494, for example. Nonetheless, its ability to act with impunity and without question had been eliminated. The questions that soon did arise, of course, would directly lead to the Protestant Reformation.
