(30-100 A.D.) According to Tertullian and Jerome, Clement of Rome was ordained by Peter and became the fourth Pope of Rome. He was the author of an "Epistle to the Corinthians", the only known manuscript of which is appended to the Alexandrian Codex, now in the British Museum. (The work appears to be oriented to Orthodox epistemologies, like Clement of Alexandria"s "Instructor".) www.newadvent.org/cathen/04012c.htm
