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.

Irenaeus of Lyons
AD 202
These are they against whom the Lord has cautioned us beforehand; and His disciple, in his Epistle already mentioned, commands us to avoid them, when he says: "For many deceivers are entered into the world, who confess not that Jesus Christ is come in the flesh. This is a deceiver and an antichrist. Take heed to them, that ye lose not what ye have wrought."
