Let us first observe that the primitive Christians were themselves accused of the same horrors which they afterwards imputed to the Manichæans; and that the justification of these equally applies to the others. "In order to have pretexts for persecuting us," said Athenagoras, in his "Apology for the Christians," "they accuse us of making detestable banquets, and of committing incest in our assemblies. It is an old trick, which has been employed from all time to extinguish virtue. Thus was Pythagoras burned, with three hundred of his disciples; Heraclitus expelled by the Ephesians; Democritus by the Abderitans; and Socrates condemned by the Athenians."
Athenagoras subsequently points out that the principles and manners of the Christians were sufficient of themselves to destroy the calumnies spread against them. The same reasons apply in favor of the Manichæans. Why else is St. Augustine, who is positive in his book on heresies, reduced in that on the morals of the Manichæans, when speaking of the horrible ceremony in question, to say simply: "They are suspected of--the world has this opinion of them--if they do not commit what is imputed to them--rumor proclaims much ill of them; but they maintain that it is false?"
Why not sustain openly this accusation in his dispute with Fortunatus, who publicly challenged him in these terms: "We are accused of false crimes, and as Augustine has assisted in our worship, I beg him to declare before the whole people, whether these crimes are true or not." St. Augustine replied: "It is true that I have assisted in your worship; but the question of faith is one thing, the question of morals another; and it is that of faith which I brought forward. However, if the persons present prefer that we should discuss that of your morals, I shall not oppose myself to them."
Fortunatus, addressing the assembly, said: "I wish, above all things, to be justified in the minds of those who believe us guilty; and that Augustine should now testify before you, and one day before the tribunal of Jesus Christ, if he has ever seen, or if he knows, in any way whatever, that the things imputed have been committed by us?" St. Augustine still replies: "You depart from the question; what I have advanced turns upon faith, not upon morals." At length, Fortunatus continuing to press St. Augustine to explain himself, he does so in these terms: "I acknowledge that in the prayer at which I assisted I did not see you commit anything impure."
