Theophylact of Ohrid, on 1John 4:2

“By this is the spirit of God known. Every spirit which confesseth that Jesus Christ is come in the flesh, is of God:”

“Next: every spirit, that is, everyone bearing the title of prophet or apostle, who confesses the Lord Jesus as having come in the flesh, is from God, and whoever does not confess this is not from God, but his dignity is from the antichrist, which you have also heard. The Apostle a little above (1 John 2:18) said that many antichrists have appeared in the world, that is, forerunners of the antichrist. And the confession of Christ's coming in the flesh must be made not only with the tongue, but also in deeds, as the Apostle Paul says: "we always carry about in the body the dying... of Jesus, that the life also of Jesus might be made manifest in our body" (2 Cor. 4:10). So then, whoever has Jesus working within him, has died to the world, no longer lives for the world but for Christ, and bears Him not only in Christ's flesh but also in his own, that one is from God. But whoever does not live for Christ but for himself and for the world, that is, for worldly pleasures, that one is not from God. Therefore Paul again says: "if there are envy, strife, and divisions among you, are you not fleshly? And are you not walking according to human custom?" (1 Cor. 3:3). He who walks according to human custom does not have the Spirit of Christ; and whoever does not have the Spirit of Christ, that is, does not live according to the teaching of Christ, that one is not Christ's.”
