The First Apology 58And raise up heretics.

And, as we said before, the devils put forward Marcion of Pontus, who is even now teaching men to deny that God is the maker of all things in heaven and on earth, and that the Christ predicted by the prophets is His Son, and preaches another god besides the Creator of all, and likewise another son. And this man many have believed, as if he alone knew the truth, and laugh at us, though they have no proof of what they say, but are carried away irrationally as lambs by a wolf, and become the prey of atheistical doctrines, and of devils. For they who are called devils attempt nothing else than to seduce men from God who made them, and from Christ His first-begotten; and those who are unable to raise themselves above the earth they have riveted, and do now rivet, to things earthly, and to the works of their own hands; but those who devote themselves to the contemplation of things divine, they secretly beat back; and if they have not a wise sober-mindedness, and a pure and passionless life, they drive them into godlessness.
