2 John 9-11

New Revised Standard Version Catholic Edition

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.
