8 Be on your guard, then, so that you will not lose what we have worked for, but will receive your reward in full.
9 Anyone who does not stay with the teaching of Christ, but goes beyond it, does not have God. Whoever does stay with the teaching has both the Father and the Son.
10 So then, if someone comes to you who does not bring this teaching, do not welcome him or her in your homes; do not even say, “Peace be with you.”
11 For anyone who wishes them peace becomes their partner in the evil things they do.
12 I have so much to tell you, but I would rather not do it with paper and ink; instead, I hope to visit you and talk with you personally, so that we shall be completely happy.
13 The children of your dear Sister send you their greetings.
