Test all things, and hold firmly that which is good.
Paul, however, may seem here to give too great liberty in teaching, when he would have all things proved; for things must be heard by us, that they may be proved, and by this means a door would be opened to impostors for disseminating their falsehoods. I answer, that in this instance he does not by any means require that an audience should be given to false teachers, whose mouth he elsewhere teaches (Titus 1:11) must be stopped, and whom he so rigidly shuts out, and does not by any means set aside the arrangement, which he elsewhere recommends so highly (1 Timothy 3:2) in the election of teachers. As, however, so great diligence can never be exercised as that there should not sometimes be persons prophesying, who are not so well instructed as they ought to be, and that sometimes good and pious teachers fail to hit the mark, he requires such moderation on the part of believers, as, nevertheless, not to refuse to hear. For nothing is more dangerous, than that moroseness, by which every kind of doctrine is rendered disgusting to us, while we do not allow ourselves to prove what is right. (618)
