Hippolytus of Rome

Marcion, adopting these sentiments, rejected altogether the generation of our Saviour. He considered it to be absurd that under the (category of a) creature fashioned by destructive Discord should have been the Logos that was an auxiliary to Friendship-that is, the Good Deity. (His doctrine,) however, was that, independent of birth, (the Logos) Himself descended from above in the fifteenth year of the reign of Tiberius Caesar, and that, as being intermediate between the good and bad Deity, He proceeded to give instruction in the synagogues. For if He is a Mediator, He has been, he says, liberated from the entire nature of the Evil Deity. Now, as he affirms, the Demiurge is evil, and his works. For this reason, he affirms, Jesus came down unbegotten, in order that He might be liberated from all (admixture of) evil. And He has, he says, been liberated from the nature of the Good One likewise, in order that He may be a Mediator, as Paul states, and as Himself acknowledges: "Why call ye me good? there is one good." These, then, are the opinions of Marcion, by means of which he made many his dupes, employing the conclusions of Empedocles. And he transferred the philosophy invented by that (ancient speculator) into his own system of thought, and (out of Empedocles) constructed his (own) impious heresy.
