The Great Schism.
This double election was the beginning of the Great Schism, which was to last for forty years and expose the papacy to new attacks on every side. There had been many anti-popes in earlier centuries, set up usually by the emperors; but there had ordinarily been little question as to who was really the legitimate pope. In the present case Europe was seriously in doubt, for it was difficult to decide whether the election of Urban had really been forced and was consequently invalid as the cardinals claimed. No one, therefore, could be perfectly sure which of the rival popes was the real successor of St. Peter. There were now two colleges of cardinals whose very existence depended upon the exercise of their right of choosing the pope. It was natural that Italy should support Urban VI, while France as naturally obeyed Clement VII; England, hostile to France, accepted Urban; Scotland, hostile to England, supported Clement.
The Church divided within itself and the consequences.
Each of two men, with seemingly equal right, now claimed to be Christ's vicar on earth; each proposed to enjoy to the full the vast prerogatives of the head of Christendom, and each denounced, and attempted to depose, the other. The schism in the headship of the Church naturally extended to the bishoprics and abbeys, and everywhere there were rival prelates, each of whom could claim that he had been duly confirmed by one pope or the other. All this produced an unprecedented scandal in the Church. It emphasized all the abuses among the clergy and gave free rein to those who were inclined to denounce the many evils which had been pointed out by Wycliffe and his followers. The condition was, in fact, intolerable and gave rise to widespread discussion, not only of the means by which the schism might be healed, but of the nature and justification of the papacy itself. The discussion which arose during these forty years of uncertainty did much to prepare the mind of western Europe for the Protestant revolt in the sixteenth century.
Idea of the supremacy of a general council.
The selfish and futile negotiations between the colleges of cardinals and the popes justified the notion that there might perhaps be a power in Christendom superior even to that of the pope. Might not a council, representing all Christendom, and inspired by the Holy Ghost, judge even a pope? Such councils had been held in the East during the later Roman Empire, beginning with the first general or ecumenical council of Nicæa under Constantine. They had established the teachings of the Church and had legislated for all Christian people and clergy.[205]
Question whether the pope or a general council is the supreme authority in the Church.
As early as 1381 the University of Paris advocated the summoning of a general council which should adjust the claims of the rival popes and give Christendom once more a single head. This raised the question whether a council was really superior to the pope or not. Those who believed that it was, maintained that the Church at large had deputed the election of the pope to the cardinals and that it might, therefore, interfere when the cardinals had brought the papacy into disrepute; that a general assembly of all Christendom, speaking under the inspiration of the Holy Spirit, was a higher authority than even the successor of St. Peter. Others strenuously denied this. They claimed that the pope received his authority over the Church immediately from Christ, and that he had always possessed supreme power from the very first, although he had not always exercised it and had permitted the earlier councils a certain freedom. No council, they urged, could be considered a general one which was called against the will of the pope, because, without the bishop of the Roman or mother church, the council obviously could not lay claim to represent all Christendom. The defenders of the papal power maintained, moreover, that the pope was the supreme legislator, that he might change or annul the act of any council or of a previous pope, that he might judge others but might not himself be judged by any one.[206]
