If there come any unto you, and bring not this doctrine, receive him not into your house, neither bid him God speed:
All Commentaries on 2 John 1:10 Go To 2 John 1
George Leo Haydock
AD 1849
Nor say to him, Hail; or peace be to you, God speed you, all hail; or use any form of saluting him, as you would a friend, much less receive or entertain him in your house: this admonition is in general to forewarn persons of the dangers which may arise from a familiarity with heretics, and such as teach evil doctrine. But by this is not forbidden civility, kindness, and a sincere charity for all men, by which we ought to wish and pray for the eternal salvation of every one. I translate Ave by peace be to you, because this was the usual salutation among the Jews, and in those times, as we see in Luke 24 and John 20.
