In conclusion, St. Leo pretends to confirm the secret crimes of the Manichæans by an argument which destroys them. "These execrable mysteries," he says, "which the more impure they are, the more carefully they are hid, are common to the Manichæans and to the Priscillianists. There is in all respects the same sacrilege, the same obscenity, the same turpitude. These crimes, these infamies, are the same which were formerly discovered among the Priscillianists, and of which the whole world is informed." The Priscillianists were never guilty of the crimes for which they were put to death. In the works of St. Augustine is contained the instructional remarks which were transmitted to that father by Orosius, and in which this Spanish priest protests that he has plucked out all the plants of perdition which sprang up in the sect of the Priscillianists; that he had not forgotten the smallest branch or root; that he exposed to the surgeon all the diseases of the sect, in order that he might labor in their cure. Orosius does not say a word of the abominable mysteries of which Leo speaks; an unanswerable proof that he had no doubt they were pure calumnies. St. Jerome also says that Priscillian was oppressed by faction, and by the intrigues of the bishops Ithacus and Idacus. Would a man be thus spoken of who was guilty of profaning religion by the most infamous ceremonies? Nevertheless, Orosius and St. Jerome could not be ignorant of crimes of which all the world had been informed. St. Martin of Tours, and St. Ambrosius, who were at Trier when Priscillian was sentenced, would have been equally informed of them. They, however, instantly solicited a pardon for him; and, not being able to obtain it, they refused to hold intercourse with his accusers and their faction. Sulpicius Severus relates the history of the misfortunes of Priscillian. Latronian, Euphrosyne, widow of the poet Delphidius, his daughter, and some other persons, were executed with him at Trier, by order of the tyrant Maximus, and at the instigation of Ithacus and Idacus, two wicked bishops, who, in reward for their injustice, died in excommunication, loaded with the hatred of God and man.
