19. So it is when men are governed by laws and works, the laws not being regulated according to the people. The case is that of the driver who would regulate the road by the movements of the wagon. True, the road is often well suited to the straight course of the wagon. But just as truly the road is, in certain places, crooked and uneven, and then the wagon must conform to the course and condition of the road. Men must adapt themselves to laws and regulations wherever possible and where the laws are beneficial. But where laws prove detrimental to men's interests, the former must yield. The ruler must wisely make allowance for love, suspending works and laws. Hence, philosophers say prudence--or circumspection or discretion as the ecclesiasts put it--is the guide and regulator of all virtues. 20. We read in a book of the ancient fathers that on a certain occasion of their assembling, the question was raised, which is really the noblest work? Various replies were given. One said prayer, another fasting; but St. Anthony was of the opinion that of all works and virtues, discretion is the best and surest way to heaven. These, however, were but childish, unspiritual ideas relating to their own chosen works. A Christian views the matter in quite a different light, and more judiciously. He concludes that neither discretion nor rashness avails before God. Only faith and love serve with him. But love is true discretion; love is the driver and the true discretion in righteous works. It always looks to the good of the neighbor, to the amelioration of his condition; just as the discretion of the world looks to the general welfare of the governed in the adjustment of political laws. Let this suffice on this point. 21. But the question arises: How can love fulfil the Law when love is but one of the fruits of faith and we have frequently said that only faith in Christ removes our sins, justifies us and satisfies all the demands of the Law? How can we make the two claims harmonize? Christ says, too (Mt 7, 12): "All things, therefore, whatsoever ye would that men should do unto you, even so do ye also unto them: for this is the law and the prophets." Thus he shows that love for one's neighbor fulfils both the Law and the prophets. Again, he says (Mt 22, 37-40): "Thou shalt love the Lord thy God ... thy neighbor as thyself. On these two the whole law hangeth, and the prophets." Where, then, does Paul stand, who says (Rom 3, 31): "Do we then make the law of none effect through faith? God forbid: nay, we establish the law." Again (Rom 3, 28): "We reckon therefore that a man is justified by faith apart from the works of the law." And again (Rom 1, 17), "The righteous shall live by faith."
