2 John 7-11

New Revised Standard Version Catholic Edition

⁷ Many deceivers have gone out into the world, those who do not confess that Jesus Christ has come in the flesh; any such person is the deceiver and the antichrist! ⁸ Be on your guard, so that you do not lose what we^[a] have worked for, but may receive a full reward. ⁹ Everyone who does not abide in the teaching of Christ, but goes beyond it, does not have God; whoever abides in the teaching has both the Father and the Son. ¹⁰ Do not receive into the house or welcome anyone who comes to you and does not bring this teaching; ¹¹ for to welcome is to participate in the evil deeds of such a person.
