⁷ For many deceivers have gone out into the world, those who do not confess Jesus Christ^[a] coming in the flesh. This person is the deceiver and the antichrist! ⁸ Watch yourselves that you do not lose what we have worked for, but receive a full reward.

⁹ Everyone who goes too far and does not remain in the teaching of Christ does not have God. The one who remains in the teaching—this person has both the Father and the Son. ¹⁰ If anyone comes to you and does not bring this teaching, do not receive him into your house and do not speak a greeting to him, ¹¹ because the one who speaks a greeting to him shares in his evil deeds.
