Against Marcion

Following the track of my original treatise, the loss of which we are steadily proceeding to restore, we come now, in the order of our subject, to treat of Christ, although this be a work of supererogation, after the proof which we have gone through that there is but one only God. For no doubt it has been already ruled with sufficient clearness, that Christ must be regarded as pertaining to no other God than the Creator, when it has been determined that no other God but the Creator should be the object of our faith.

Him did Christ so expressly preach, while the apostles one after the other also so clearly affirmed that Christ belonged to no other God than Him whom He Himself preached— that is, the Creator— that no mention of a second God (nor, accordingly, of a second Christ) was ever agitated previous to Marcion's scandal. This is most easily proved by an examination of both the apostolic and the heretical churches, from which we are forced to declare that there is undoubtedly a subversion of the rule (of faith), where any opinion is found of later date, — a point which I have inserted in my first book. A discussion of it would unquestionably be of value even now, when we are about to make a separate examination into (the subject of) Christ; because, while proving Christ to be the Creator's Son, we are effectually shutting out the God of Marcion.

Truth should employ all her available resources, and in no limping way. In our compendious rules of faith, however, she has it all her own way. But I have resolved, like an earnest man, to meet my adversary every way and everywhere in the madness of his heresy, which is so great, that he has found it easier to assume that that Christ has come who was never heard of, than He who has always been predicted.
