They [the Gnostics] possess paintings—some, moreover, have images made of gold, silver and other materials—and say that such things are portraits in relief of Jesus, and made by Pontius Pilate! That is, the reliefs are portraits of the actual Jesus during his sojourn among men! (10) They possess images like these in secret, and of certain philosophers besides–Pythagoras, Plato, Aristotle, and the rest—and also place other reliefs of Jesus with these philosophers. And having erected them, they worship them and celebrate heathen mysteries. For once they have set these images up, they then follow the customs of heathen–yet what are
customs of the heathen but sacrifices and the rest? (11) they say that salvation is of the soul only, and not of bodies.
