Epistle Sermons, Vol. 3: Trinity Sunday to Advent

by Martin Luther

Thirteenth Sunday After Trinity

Text: Galatians 3, 15-22.

15 Brethren, I speak after the manner of men: Though it be but a man's covenant, yet when it hath been confirmed, no one maketh it void, or addeth thereto. 16 Now to Abraham were the promises spoken, and to his seed. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ. 17 Now this I say: A covenant confirmed beforehand by God, the law, which came four hundred and thirty years after, doth not disannul, so as to make the promise of none effect. 18 For if the inheritance is of the law, it is no more of promise: but God hath granted it to Abraham by promise. 19 What then is the law? It was added because of transgressions, till the seed should come to whom the promise hath been made; and it was ordained through angels by the hand of a mediator. 20 Now a mediator is not a mediator of one; but God is one. 21 Is the law then against the promises of God? God forbid: for if there had been a law given which could make alive, verily righteousness would have been of the law. 22 But the scripture shut up all things under sin, that the promise by faith in Jesus Christ might be given to them that believe.

GOD'S TESTAMENT AND PROMISE IN CHRIST.

1. This is a keen, severe epistle, one that is unintelligible to the ordinary man. Because the doctrine it contains has not hitherto been employed and enforced, it has not been understood. It is also too long and rich to be treated briefly. But it is fully explained in the complete commentary on this epistle to the Galatians, where those who will may read it. The substance of it is, that here, as in the whole epistle, Paul would earnestly constrain the Christian to distinguish between the righteousness of faith and the righteousness of works or of the Law. In order that we may note to some extent the main points Paul makes in this text, we remark that he emphasizes two things. He treats first of the doctrine that we are justified by faith alone, and he maintains this, after giving many reasons and proofs, by saying in effect:

2. In this connection you should note that no one, whether Jew or gentile, is justified by works or by the Law. For the Law was given four hundred and thirty years after the promise of a Savior had been made to Abraham (who was to be the father of all the people of God) and the assurance that all nations should be blessed in him. It was given after it had been testified of Abraham that his faith was imputed to him for righteousness. And as he was justified and received the blessing by reason of his faith, so also his children and descendants were justified and received the blessing through the same faith in that seed for whose sake the blessing had been promised to all the world. For in his dealings with the Jews and with the whole world, God always promised his grace and the forgiveness of sins (and that means to be blessed of God) even when there was as yet no Law by which they might pretend to become righteous, and before Moses was born.

3. Therefore the Law, being given to this people only after the lapse of so long a period, could not have been given to them for justification; otherwise it would have been given earlier. Or if it had been necessary for righteousness, then Abraham and his children up to that date could not have been justified at all. Indeed God designed that the Law should be given so long after Abraham. Undoubtedly he would have been able to give it to the fathers much earlier if he had seen fit to do so. Apparently he desired thereby to teach that the Law was not given to the end that God's grace and blessing should be acquired through it, but that these come from the pure mercy of God which was promised and bestowed so long before upon Abraham and those who believed.

4. Therefore Paul concludes: How could the Law produce righteousness for those who lived before Moses, since Moses was the first through whom the Law was given; and since even before his time there were holy people and people who were saved? Whence did they derive their righteousness? Certainly not from the fact that they had offered sacrifice at Jerusalem, but from the fact that they believed the Word in which God promised to bless them through the coming seed, Christ. Hence, those also who lived afterwards could not have been justified by the Law; for they did not receive the grace of God in a different way from that in which those who went before had received it. God did not annul or revoke by the Law the promise of blessing which he had made and freely bestowed without the Law.

5. Here some might desire to show their wisdom and say to Paul: Although the fathers did not have the Law of Moses, they had the same Word of God which teaches the ten commandments and which was implanted in the human heart from the beginning of the world, whence also it is called the law of nature or the natural law; and the same law was afterwards given publicly to the Jewish people and comprehended in the ten commandments. It might also be said that Moses borrowed the ten commandments from the fathers, to which Christ testifies in John 7, 22. For it is certain that the fathers from the beginning taught them and urged them upon their children and descendants. With what consistency, then, does Paul conclude that the fathers were not justified by the Law because it was not given until four hundred years after Abraham's time; as if the fathers before that time had no Law?
