The Refutation of All Heresies

But there was a certain Theodotus, a native of Byzantium, who introduced a novel heresy. He announces tenets concerning the originating cause of the universe, which are partly in keeping with the doctrines of the true Church, in so far as he acknowledges that all things were created by God. Forcibly appropriating, however, (his notions of) Christ from the school of the Gnostics, and of Cerinthus and Ebion, he alleges that (our Lord) appeared in some such manner as I shall now describe.

(According to this, Theodotus maintains) that Jesus was a (mere) man, born of a virgin, according to the counsel of the Father, and that after he had lived promiscuously with all men, and had become pre-eminently religious, he subsequently at his baptism in Jordan received Christ, who came from above and descended (upon him) in form of a dove. And this was the reason, (according to Theodotus,) why (miraculous) powers did not operate within him prior to the manifestation in him of that Spirit which descended, (and) which proclaims him to be the Christ. But (among the followers of Theodotus) some are disposed (to think) that never was this man made God, (even) at the descent of the Spirit; whereas others (maintain that he was made God) after the resurrection from the dead.
