Polycarp of Smyrna, 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:”

“"For whosoever does not confess that Jesus Christ has come in the flesh, is antichrist;" and whosoever does not confess the testimony of the cross, is of the devil; and whosoever perverts the oracles of the Lord to his own lusts, and says that there is neither a resurrection nor a judgment, he is the first-born of Satan. Wherefore, forsaking the vanity of many, and their false doctrines, let us return to the word which has been handed down to us from the beginning; "watching unto prayer," and persevering in fasting; beseeching in our supplications the all-seeing God "not to lead us into temptation," as the Lord has said: "The spirit truly is willing, but the flesh is weak."”
