To be justified by faith does not mean that we are to be saved by our opinions. To say that a man can be saved by holding certain opinions, instead of certain other opinions, is to say what is contradicted by all experience; for experience shows us that there are good men holding every variety of opinion, and bad men holding every variety of opinion. But God saves men by making them good: therefore men are not saved by their opinions. Let us suppose that men are to be saved by the opinion that Jesus is the Christ: then we ought to find that all men holding that opinion are on the way of salvation; that is, are becoming good men. But this is far from being the case. In fact, the connection between mere opinion of any kind, and goodness, is very distant and indirect. No doubt, in the long run, opinion affects character; but it is only in the long run that it does so. And, at all events, the doctrine of the New Testament is very distinct and decided, that men may hold very sound opinions, and yet not be in the way of salvation. The Scribes and Pharisees held very sound opinions; and Jesus told his disciples to do whatever they said, but not to imitate their works; for their doctrine was much better than their lives. Nor does the apostle mean to say that one can be saved without morality. He certainly does not mean to undervalue goodness; for, in that case, he would contradict his own teachings, which uniformly declare, as all the rest of the Bible declares, that without holiness no man can see the Lord. It is certainly a very superficial view which is satisfied with supposing that an earnest man, as the apostle certainly was, devoting his life, as he certainly did, to the teaching of Christianity, with such a grand intellect as he certainly possessed, could assert with so much energy a doctrine plainly contradicting common sense, daily observation, the plain teachings of Jesus, and his own uniform doctrine elsewhere. Some persons have a short method of getting over the difficulty by saying that Paul did not himself know what he meant. They assume that he was talking at random. It would be about as wise, when we open Newton’s “Principia,” and cannot understand it, to say that Newton was talking at random; or, when we cannot understand Plato or some other profound metaphysician, to declare directly that he did not himself know what he was talking about. No doubt, this is the shortest and easiest way of getting out of such difficulties, but perhaps not the most modest, nor the most wise. When an earnest man, a profound man, a man in the highest degree practical, a man who has done the greatest work for Christianity which has been done since its foundation, sums up his doctrine in a comprehensive maxim like this, it is, perhaps, wise to admit, at once, that he had a meaning, and probably an important one.
