St. Iren. v. 2. “Vain also are those who say that the Lord came to what was another’s, as though coveting it, in order to present that man who had been made by another, to that God, who had neither made nor ordered him, yea, rather, who had deserted him from men’s first original formation. His coming, therefore, is not just, coming as He did by their account to what was none of His.” [Ibid. pp. 527, 528.] In Lib. iii. 11, he specifies Marcion as teaching this doctrine.
