No doubt the decretals of Siricius had rendered compulsory the celibacy of the priesthood throughout Gaul and Spain. The machinery of the hierarchy may readily have stifled open opposition, however frequent may have been the secret infractions of the rule. This may perhaps have contributed to the success of Vigilantius. Even his former master, St. Sulpicius Severus, and St. Exuperius, Bishop of Toulouse, were inclined to favor his reforms. That they spread with dangerous rapidity throughout Gaul from south to north is shown by the fact that in 404 Victricius, Bishop of Rouen, and in 405 St. Exuperius of Toulouse applied to Innocent I. for advice as to the manner in which they should deal with the new heresy. It also counted numerous adherents throughout Spain, among whom even some bishops were enumerated. The alarm was promptly sounded, and the enginery of the church was brought to bear upon the hardy heretic. The vast reputation and authority of Jerome lent force to the coarse invective with which he endeavored to overwhelm his whilom acquaintance, and though the nickname of Dormitantius which he bestowed on Vigilantius was a sarcasm neither very severe nor very refined, the disgusting exaggeration of his adversary’s tenets in which he as usual indulged had doubtless its destined effect.[127] Pope Innocent was not backward in asserting the authority of Rome and the inviolable nature of the canon. In his epistle to Victricius, he repeated the decretal of Siricius, but in a somewhat more positive form;[128] while in the following year (405) he confirmed the vacillating faith of Exuperius by declaring that any violation of the strictest celibacy on the part of priest or deacon subjects the offender to the deprivation of his position.[129] As in the previous effort of Siricius, however, ignorance is admitted as an excuse, entitling him who can plead it to retain his grade without hope of preferment—and the test of this ignorance is held to be the canon of 385. This latter point is noteworthy, for it is a tacit confession of the novelty of the rule, although Innocent labored at great length to prove both its antiquity and necessity from the well-known texts of St. Paul and the Levitical observances. Yet no intermediate authority was quoted, and punishment was only to be inflicted on those who could be proved to have seen the decretal of Siricius.
