Galatians 3:23

Whence the law was rightly said to have been given by Moses, being a rule of right and wrong; and we may call it with accuracy the divine ordinance ( θεσμός ), inasmuch as it was given by God through Moses. It accordingly conducts to the divine. Paul says: “The law was instituted because of transgressions, till the seed should come, to whom the promise was made.” Then, as if in explanation of his meaning, he adds: “But before faith came, we were kept under the law, shut up,” manifestly through fear, in consequence of sins, “unto the faith which should afterwards be revealed; so that the law was a schoolmaster to bring us to Christ, that we should be justified by faith.” The true legislator is he who assigns to each department of the soul what is suitable to it and to its operations. Now Moses, to speak comprehensively, was a living law, governed by the benign Word. …

7. Augustin replied: If you allow, in consideration of the authority of the Gospel, that Christ said that He came not to destroy the law and the prophets, but to fulfill them, you should show the same consideration to the authority of the apostle, when he says, "All these things were our examples;" and again of Christ, "He was not yea and nay, but in Him was yea; for all the promises of God are in Him yea;" that is, they are set forth and fulfilled in Him. In this way you will see in the clearest light both what law Christ fulfilled, and how He fulfilled it. It is a vain attempt that you make to escape by your three kinds of law and your three kinds of prophets. It is quite plain, and the New Testament leaves no doubt on the matter, what law and what prophets Christ came not to destroy, but to fulfill. The law given by Moses is that which by Jesus Christ became grace and truth. …

14. And if the righteous men of old, who saw in the sacraments of their time the promise of a future revelation of faith, which even then their piety enabled them to discern in the dim light of prophecy, and by which they lived, for the just can live only by faith; if, then, these righteous men of old were ready to suffer, as many actually did suffer, all trials and tortures for the sake of those typical sacraments which prefigured things in the future; if we praise the three children and Daniel, because they refused to be defiled by meat from the king’s table, from their regard for the sacrament of their day; if we feel the strongest admiration for the Maccabees, who refused to touch food which Christians lawfully use; how much more should a Christian in our day be ready to suffer all things for Christ’s baptism, for Christ’s Eucharist, for Christ’s sacred sign, since these are proofs o …

After saying, “Not according to the covenant which I made with their fathers in the day that I took them by the hand, to bring them out of the land of Egypt,” observe what He adds: “Because they continued not in my covenant.” He reckons it as their own fault that they did not continue in God’s covenant, lest the law, which they received at that time, should seem to be deserving of blame. For it was the very law that Christ “came not to destroy, but to fulfil.” Nevertheless, it is not by that law that the ungodly are made righteous, but by grace; and this change is effected by the life-giving Spirit, without whom the letter kills. “For if there had been a law given which could have given life, verily righteousness should have been by the law. …

But before I proceed further, see what he has said. When treating the question about the difference of sins, and starting as an objection to himself, what certain persons allege, “that some sins are light by their very frequency, their constant irruption making it impossible that they should be all of them avoided;” he thereupon denied that it was “proper that they should be censured even as light offences, if they cannot possibly be wholly avoided.” He of course does not notice the Scriptures of the New Testament, wherein we learn that the intention of the law in its censure is this, that, by reason of the transgressions which men commit, they may flee for refuge to the grace of the Lord, who has pity upon them, “the schoolmaster” “shutting them up unto the same faith which should afterwards be revealed;” that by it their transgressions may be forgiven, and then not again be committed, …

This is what we say; this is that about which they object to us that we say “that the law was so given as to be a cause of greater sin.” They do not hear the apostle saying, “For the law worketh wrath; for where no law is, there is no transgression;” and, “The law was added for the sake of transgression until the seed should come to whom the promise was made;” and, “If there had been a law given which could have given life, righteousness should altogether have been by the law; but the Scripture hath concluded all under sin, that the promise by faith of Jesus Christ might be given to them that believe.” Hence it is that the Old Testament, from the Mount Sinai, where the law was given, gendereth to bondage, which is Agar. …

Ver. 23 . “But before faith came, we were kept inward under the Law, shut up unto the faith which should afterwards be revealed.” Here he clearly puts forward what I have stated: for the expressions “we were kept” and “shut up,” signify nothing else than the security given by the commandments of the Law; which like a fortress fenced them round with fear and a life conformable to itself, and so preserved them unto Faith.
