Peter.

        The last of the ante-Nicene teachers at Alexandria was Peter, who became bishop in the year 300. It was he who brought Origen's direct influence at Alexandria to an end, although he was almost constantly engaged in controversy during his brief episcopate, which ended with his martyrdom in 311. Administrative conflicts led to the Melitian schism; theological difficulties may have brought Peter to excommunicate Arius. Apart from small fragments, we possess from Peter a letter warning the Alexandrians against Melitius, self-appointed primate of Egypt, and fourteen “canons” on penance, chiefly concerned with those who had abandoned Christianity before the year 306.
