“(Concil. Con. ii. Collat. 8.) How is it that some do presume to say that these things are said only of the living? Know they not that the sentence of anathema is nothing else but separation? They are to be avoided who are held of grievous faults, whether they are among the living, or not. For it is always behoveful to fly from the wicked. Moreover there are divers letters read of Augustine of religious memory, who was of great renown among the African bishops, which affirmed that heretics ought to be anathematized even after death. (vid. Aug. Ep. 185. 4.) Such an ecclesiastical tradition other African Bishops also have preserved. And the Holy Roman Church also has anathematized some Bishops after death, although no accusation had been brought against their faith in their lifetimeu.”
