For many deceivers are entered into the world, who confess not that Jesus Christ has come in the flesh. This is a deceiver and an antichrist.

Because many seducers are going out into the world. He now passes to the second branch of his epistle, from charity to evangelical truth. For these two virtues are inseparable sisters and companions. Now the word because gives the reason for what he had said in the verse preceding. "I have said that ye should walk in charity, should make progress in the commandment of Gospel truth and charity, because many seducers are gone out into the world, who endeavour to overturn this truth, and as a consequence Christian charity, and to tear it from you. Of such therefore ye ought to beware as of wolves. For they strive to draw you away from union with Christ to their own conventicles of Satan."
This is a seducer and an antichrist. Whosoever thinks, or teaches, that Christ has not come in the flesh, has not been incarnate; this man is a deceiver.
