1:9. Whosoever revolteth and continueth not in the doctrine of Christ hath not God. He that continueth in the doctrine, the same hath both the Father and the Son.
1:10. If any man come to you and bring not this doctrine, receive him not into the house nor say to him: God speed you.
Nor say to him, God speed you... This admonition is in general, to forewarn the faithful of the dangers which may arise from a familiarity with those who have prevaricated and gone from the true faith, and with such as teach false doctrine. But this is not forbidding a charity for all men, by which we ought to wish and pray for the eternal salvation of every one, even of our enemies.
1:11. For he that saith unto him: God speed you, communicateth with his wicked works.
1:12. Having more things to write unto you, I would not by paper and ink: for I hope that I shall be with you and speak face to face, that your joy may be full.
1:13. The children of thy sister Elect salute thee.
