Didymus the Blind, on 1John 4:3

“And every spirit that dissolveth Jesus, is not of God: and this is Antichrist, of whom you have heard that he cometh, and he is now already in the world.”

“If a spirit dissolves the divine-human unity of Christ and thinks that the pure Word of God is outside all flesh, and cannot really be a man, and states that everything done in his incarnation is a fantasy, then that spirit is not from God. But someone will say that there are many heretics who do accept the incarnation, the Montanists for instance. The answer to them is that just as no one says that Jesus is Lord except by the Holy Spirit, so the Montanists do not accept all the implications of incarnational belief. For those who say that Jesus is Lord but who do not follow his commandments do not have the Holy Spirit. Although they honor him with their lips, their hearts are far from him.”
