Leo the Great (Serm. xv. cap. 4) speaks of the madness of the later Manichees as including all errors and impieties:  “all profanity of Paganism, all blindness of the carnal Jews, the illicit secrets of the magic art, the sacrilege and blasphemy of all heresies, flowed together in that sect as into a sort of cess-pool of all filth.”  Leo summoned those whom they called the “elect,” both men and women, before an assembly of Bishops and Presbyters, and obtained from these witnesses a full account of the execrable practices of the sect, in which, as he declares, “their law is lying, their religion the devil, their sacrifice obscenity.”
