"How much of the Truth may I give up without imperiling my salvation?" NOT ANY. The Truth is our city of refuge; in it we are safe. Immediately we wander outside of it, our life is in danger. A few hours spent on Paul's writings, provided we are open to conviction, will assure us upon this point.
Even apart from direct teaching, are we not told that the existence of false teachers caused Paul many a tear? There is no intelligible explanation of this away from the fact that he knew error meant destruction to those who embraced it.
Again we read: "But of these who seemed to be somewhat (whatever they were it maketh no matter to me)-to whom we give place by subjection, no, not for an hour!-that the TRUTH of the Gospel might continue with you" (Gal. 2:5-6).
This passage also indicates Paul's estimation of error, for he was not the man to speak without good and weighty motives. The path of error is the path of death. This may offend "unruly and vain talkers and deceivers," but what of that? Because the serpent says, "Ye shall not surely die," we are not bound to believe it.
