The violation of the vow of chastity was so common that only the most outrageous indecency could excite comment, and the spiritual authorities, whom the Church had appointed to exercise a censorship over public morals, hesitated to perform their duties lest their own delinquencies might thereby be exposed. It was considered not only meritorious, but convenient, to have a clergyman for a lover, on account of the facility of concealment and the certainty of immediate absolution. The presence of the mistresses of bishops, priests, and canons insulted the wives of honest nobles and burghers at coronations and tournaments. The vicinity of abbeys and convents swarmed with the natural children of ecclesiastics. These members of priestly households were liberally provided for from revenues ostensibly collected for pious uses and the propagation of religious truth. So degraded had some of the monks become that they utilized even the House of God for the basest purposes. Guyot de Provins, a writer of the thirteenth century and himself the member of a monastic fraternity, relates that he had seen Cistercians turn church-yards into pigsties and tether asses in chapels. In addition to immoderate indulgence in the strongest of wines, the successors of Pachomius and Antony held eating contests, in which the palm was awarded to the brother possessing the greatest abdominal capacity. Among these were the Glutton Masses of England, celebrated five times a year in honor of the Virgin, when the parish church was made the scene of the voracious exploits of the priest and the clerks, who contended for this enviable distinction with an ardor that often terminated in riot. Every effort to reform these depraved communities proved futile. The abbot who attempted to correct the vices of his flock was harassed until he was glad to relinquish his unpromising task or abandon his charge. If he boldly attempted to enforce his authority, he stood an excellent chance of being poisoned. The famous Abelard narrowly escaped this fate, and the pronounced and vindictive hostility manifested by the inmates of his abbey finally compelled him to insure his safety by flight. Even the determined character of Cardinal Ximenes was forced to succumb to the obstinacy of his Franciscan brethren, whose extortions and irregular lives had excited his horror and disgust. For seven years, William, Bishop of Paderborn, employed in vain the authority vested in his high office to free the monasteries of his diocese from the scandal produced by the vices of their occupants.
