4. The Spirit, therefore, descending under the predestined dispensation, and the Son of God, the Only-begotten, who is also the Word of the Father, coming in the fulness of time, having become incarnate in man for the sake of man, and fulfilling all the conditions of human nature, our Lord Jesus Christ being one and the same, as He Himself the Lord doth testify, as the apostles confess, and as the prophets announce,—all the doctrines of these men who have invented putative Ogdoads and Tetrads, and imagined subdivisions [of the Lord’s person], have been proved falsehoods. These men do, in fact, set the Spirit aside altogether; they understand that Christ was one and Jesus another; and they teach that there was not one Christ, but many. And if they speak of them as united, they do again separate them: for they show that one did indeed undergo sufferings, but that the other remained impassible; that the one truly did ascend to the Pleroma, but the other remained in the intermediate place; that the one does truly feast and revel in places invisible and above all name, but that the other is seated with the Demiurge, emptying him of power. It will therefore be incumbent upon thee, and all others who give their attention to this writing, and are anxious about their own salvation, not readily to express acquiescence when they hear abroad the speeches of these men: for, speaking things resembling the [doctrine of the] faithful, as I have already observed, not only do they hold opinions which are different, but absolutely contrary, and in all points full of blasphemies, by which they destroy those persons who, by reason of the resemblance of the words, imbibe a poison which disagrees with their constitution, just as if one, giving lime mixed with water for milk, should mislead by the similitude of the colour; as a man superior to me has said, concerning all that in any way corrupt the things of God and adulterate the truth, “Lime is wickedly mixed with the milk of God.”
