But though we, or an angel from heaven, preach any other gospel to you than that which we have preached to you, let him be accursed.…
And therefore ye may again take notice of it, that it is not only said, "Besides what we have preached," but "What ye have received." The receiver is as bad as the thief in this particular: and as it is a cursed thing to scatter error, so it is as cursed a thing to take it up, and carry it home, and keep it by us, or nourish it with us; which therefore we should now all be persuaded (in the fear of God) to avoid and shun what we can.
(T. Horton, D. D.)
