From the time of Gelasius II. (§ 96, 11) it had been the custom of the popes whenever Italy became too hot for them to fly to France, and from France they had obtained help to deliver Italy from the tyranny of the latest representatives of the Hohenstaufens. But when Boniface VIII. dared boldly to assert the universal sovereignty of the papacy even over France itself, this presumption wrought its own overthrow. The consequence was a seventy years’ exile of the papal chair to the banks of the Rhone, with complete subjugation under French authority. Under the protection of the French court, however, the popes found Avignon a safe asylum, and from thence they issued the most extravagant hierarchical claims, especially upon Germany. The return of the papal court to Rome was the occasion of a forty years’ schism, during which two popes, for a time even three, are seen hurling anathemas at one another. The reforming Councils of Pisa, Constance, and Basel sought to put an end to this scandal and bring about a reformation in the head and the members. The fathers in these councils, however, in accordance with the prevalent views of the age, maintained the need of one visible head for the government of the church, such as was afforded by the papacy. But the corruptions of the papal chair led them to adopt the old theory that the highest ecclesiastical authority is not the pope but the voice of the universal church expressed in the œcumenical councils, which had jurisdiction over even the popes. The successful carrying out of this view was possible only if the several national churches which had come now more decidedly than ever to regard themselves as independent branches of the great ecclesiastical organism, should heartily combine against the corrupt papacy. But this they did not do. They were contented with making separate attacks, in accordance with their several selfish interests. Hence papal craft found little difficulty in rendering the strong remonstrances of these councils fruitless and without result. The papacy came forth triumphant, and during the 15th century, the age of the Renaissance, reached a degree of corruption and moral turpitude which it had not approached since the 10th century. The vicars of God now used their spiritual rank only to further their ambitious worldly schemes, and by the most scandalous nepotism (the so-called nephews being often bastards of the popes, who were put into the highest and most lucrative offices) as well as by their own voluptuousness, luxury, revelry, and love of war, brought ruin upon the church and the States of the Church.
