For many deceivers [heretics, posing as Christians] have gone out into the world, those who do not acknowledge and confess the coming of Jesus Christ in the flesh (bodily form). This [person, the kind who does this] is the deceiver and the antichrist [that is, the antagonist of Christ].

Every one who goes beyond the limits of the Teaching of the Christ has failed to find God; the man who keeps to that Teaching--he has found both the Father and the Son.

If any man comes to you, and does not bring this doctrine, do not receive him into a house, and do not speak to him to rejoice.

for the man who welcomes him is sharing with him in his wicked work.

I have a great deal to write to you, but I do not mean to use ink and paper; I hope to visit you and have a talk with you, so that your joy may be unimpaired.
