Many citations of a like nature are taken from Luke and Mark to prove the _Logos_ doctrine of John's Gospel. Irenaeus even brings John upon the stand to prove the doctrine of an incarnate Christ! which John himself was the first to communicate. "John, the disciple of the Lord, preaches this faith, and seeks, by the proclamation of the Gospel, to remove that error which by Cerinthus had been disseminated among men, and a long time previously by those termed Nicolaitans, who are an offset of that 'knowledge' falsely so called, that he might confound them, and persuade them that there is but one God, who made all things by His Word; and not, as they allege, that the Creator was one, but the Father of the Lord another; and that the Son of the Creator was, forsooth, one, but the Christ from above another."... "The disciple of the Lord, therefore, desiring to put an end to all such doctrines, and to establish the rule of truth in the church, that there is one Almighty God, who made all things by His Word, both visible and invisible; showing at the same time, that by the _Word_, through whom God made the creation, He also bestowed salvation on the men included in the creation: thus commenced His teaching in the Gospel: 'In the beginning was the Word, and the Word was with God, and the Word was God.'" (Bopkm. chap. 11, sec. 1.) He makes many references to John, and sums up his complaints against the Gnostics in the following words: "But according to the opinion of no one of the heretics was the Word of God made flesh. For if any one carefully examines the systems of them all, he will find that the Word of God is brought in by all of them as not having become _incarnate (sine carne)_ and _impassible_, as is also the Christ from above." (Book III. chap, in, sec. 3.) The writer cites many passages from the epistle of Peter, all confirming the _Logos_ doctrines of John. The following is the heading of chap. xxii. book III.: "_Christ assumed actual flesh, conceived and born of the Virgin_." In this chapter the doctrine of the incarnation is elaborately argued, and proof supplied from many quarters; but as there is a great sameness in the argument throughout, it would only tire the reader to pursue the subject any further.
