Persons converted from heresies, that is, of the Novatians, Photinians, and Quartodecimans, whether they were catechumens or communicants among them, shall not be received until they shall have anathematized every heresy, and particularly that in which they were held; and afterwards those who among them were called communicants, having thoroughly learned the symbols of the faith, and having been anointed with the holy chrism, shall so communicate in the holy Mysteries.
