Against Heresies

by Irenaeus of Lyons

The relation of Plotinus's philosophy to Gnosticism was brought out by C. Schmidt in 1901. That Alexandrian thought had some share at least in the development of Christian Gnosticism is clear from the fact that the bulk of Gnostic literature which we possess comes to us from Egyptian (Coptic) sources. That this share was not a predominant one is, however, acknowledged by O. Gruppe in his "Griechische Mythologie und Religionsgeschichte" (1902). It is true that the Greek mysteries, as G. Anrich pointed out in 1894, had much in common with esoteric Gnosticism; but there remains the further question, in how far these Greek mysteries, as they are known to us, were the genuine product of Greek thought, and not much rather due to the overpowering influence of Orientalism.
