VERSE 20. Now a mediator is not a mediator of one.
Here the Apostle briefly compares the two mediators: Moses and Christ. "A mediator," says Paul, "is not a mediator of one." He is necessarily a mediator of two: The offender and the offended. Moses was such a mediator between the Law and the people who were offended at the Law. They were offended at the Law because they did not understand its purpose. That was the veil which Moses put over his face. The people were also offended at the Law because they could not look at the bare face of Moses. It shone with the glory of God. When Moses addressed the people he had to cover his face with that veil of his. They could not listen to their mediator Moses without another mediator, the veil. The Law had to change its face and voice. In other words, the Law had to be made tolerable to the people.
Thus covered, the Law no longer spoke to the people in its undisguised majesty. It became more tolerable to the conscience. This explains why men fail to understand the Law properly, with the result that they become secure and presumptuous hypocrites. One of two things has to be done: Either the Law must be covered with a veil and then it loses its full effectiveness, or it must be unveiled and then the full blast of its force kills. Man cannot stand the Law without a veil over it. Hence, we are forced either to look beyond the Law to Christ, or we go through life as shameless hypocrites and secure sinners.
Paul says: "A mediator is not a mediator of one." Moses could not be a mediator of God only, for God needs no mediator. Again, Moses could not be a mediator of the people only. He was a mediator between God and the people. It is the office of a mediator to conciliate the party that is offended and to placate the party that is the offender. However, Moses' mediation consisted only in changing the tone of the Law to make it more tolerable to the people. Moses was merely a mediator of the veil. He could not supply the ability to perform the Law.
What do you suppose would have happened if the Law had been given without a mediator and the people had been denied the services of a go- between? The people would have perished, or in case they had escaped they would have required the services of another mediator to preserve them alive and to keep the Law in force. Moses came along and he was made the mediator. He covered his face with a veil. But that is as much as he could do. He could not deliver men's consciences from the terror of the Law. The sinner needs a better mediator.
That better mediator is Jesus Christ. He does not change the voice of the Law, nor does He hide the Law with a veil. He takes the full blast of the wrath of the Law and fulfills its demands most meticulously.
Of this better Mediator Paul says: "A mediator is not a mediator of one." We are the offending party; God is the party offended. The offense is of such a nature that God cannot pardon it. Neither can we render adequate satisfaction for our offenses. There is discord between God and us. Could not God revoke His Law? No. How about running away from God? It cannot be done. It took Christ to come between us and God and to reconcile God to us. How did Christ do it? "Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross." (Col. 2:14.)
This one word, "mediator," is proof enough that the Law cannot justify. Otherwise we should not need a mediator.
In Christian theology the Law does not justify. In fact it has the contrary effect. The Law alarms us, it magnifies our sins until we begin to hate the Law and its divine Author. Would you call this being justified by the Law?
Can you imagine a more arrant outrage than to hate God and to abhor His Law? What an excellent Law it is. Listen: "I am the Lord thy God, which have brought thee out of the land of Egypt, out of the house of bondage. Thou shalt have no other gods. . .showing mercy unto thousands . . . honor thy father and thy mother; that thy days may be long upon the land. . ." (Ex. 20:2, 3, 6, 12.) Are these not excellent laws, perfect wisdom? "Let not God speak with us, lest we die," cried the children of Israel. Is it not amazing that a person should refuse to hear things that are good for him? Any person would be glad to hear, I should think, that he has a gracious God who shows mercy unto thousands. Is it not amazing that people hate the Law that promotes their safety and welfare, e.g., "Thou shalt not kill; thou shalt not commit adultery; thou shalt not steal"?
The Law can do nothing for us except to arouse the conscience. Before the Law comes to me I feel no sin. But when the Law comes, sin, death, and hell are revealed to me. You would not call this being made righteous. You would call it being condemned to death and hell-fire.
VERSE 20. But God is one.
God does not offend anybody, therefore He needs no mediator. But we offend God, therefore we need a mediator. And we need a better mediator than Moses. We need Christ.
VERSE 21. Is the law then against the promises of God?
Before he digressed Paul stated that the Law does not justify. Shall we then discard the Law? No, no. It supplies a certain need. It supplies men with a needed realization of their sinfulness. Now arises another question: If the Law does no more than to reveal sin, does it not oppose the promises of God? The Jews believed that by the restraint and discipline of the Law the promises of God would be hastened, in fact earned by them.
Paul answers: "Not so. On the contrary, if we pay too much attention to the Law the promises of God will be slowed up. How can God fulfill His promises to a people that hates the Law?"
VERSE 21. God forbid.
God never said to Abraham: "In thee shall all the nations of the earth be blessed because thou hast kept the Law." When Abraham was still uncircumcised and without the Law or any law, indeed, when he was still an idol worshiper, God said to him: "Get thee out of thy country, etc.; I am thy shield, etc.; In thy seed shall all the nations of the earth be blessed." These are unconditional promises which God freely made to Abraham without respect to works.
This is aimed especially at the Jews who think that the promises of God are impeded by their sins. Paul says: "The Lord is not slack concerning His promises because of our sins, or hastens His promises because of any merit on our part." God's promises are not influenced by our attitudes. They rest in His goodness and mercy.
Just because the Law increases sin, it does not therefore obstruct the promises of God. The Law confirms the promises, in that it prepares a person to look for the fulfillment of the promises of God in Christ.
The proverb has it that Hunger is the best cook. The Law makes afflicted consciences hungry for Christ. Christ tastes good to them. Hungry hearts appreciate Christ. Thirsty souls are what Christ wants. He invites them: "Come unto me, all ye that labour and are heavy laden, and I will give you rest." Christ's benefits are so precious that He will dispense them only to those who need them and really desire them.
VERSE 21. For if there had been a law given which could have given life, verily righteousness should have been by the law.
The Law cannot give life. It kills. The Law does not justify a person before God; it increases sin. The Law does not secure righteousness; it hinders righteousness. The Apostle declares emphatically that the Law of itself cannot save.
Despite the intelligibility of Paul's statement, our enemies fail to grasp it. Otherwise they would not emphasize free will, natural strength, the works of supererogation, etc. To escape the charge of forgery they always have their convenient annotation handy, that Paul is referring only to the ceremonial and not to the moral law. But Paul includes all laws. He expressly says: "If there had been a law given."
There is no law by which righteousness may be obtained, not a single one. Why not?
VERSE 22. But the Scripture hath concluded all under sin.
Where? First in the promises concerning Christ in Genesis 3:15 and in Genesis 22:18, which speak of the seed of the woman and the seed of Abraham. The fact that these promises were made unto the fathers concerning Christ implies that the fathers were subject to the curse of sin and eternal death. Otherwise why the need of promises?
Next, Holy Writ "concludes" all under sin in this passage from Paul: "For as many as are of the works of the law are under the curse." Again, in the passage which the Apostle quotes from Deuteronomy 27:26, "Cursed is every one that continueth not in all things which are written in the book of the law to do them." This passage clearly submits all men to the curse, not only those who sin openly against the Law, but also those who sincerely endeavor to perform the Law, inclusive of monks, friars, hermits, etc.
The conclusion is inevitable: Faith alone justified without works. If the Law itself cannot justify, much less can imperfect performance of the Law or the works of the Law, justify.
VERSE 22. That the promise by faith of Jesus Christ might be given to them that believe.
The Apostle stated before that "the Scripture hath concluded all under sin." Forever? No, only until the promise should be fulfilled. The promise, you will recall, is the inheritance itself or the blessing promised to Abraham, deliverance from the Law, sin, death, and the devil, and the free gift of grace, righteousness, salvation, and eternal life. This promise, says Paul, is not obtained by any merit, by any law, or by any work. This promise is given. To whom? To those who believe. In whom? In Jesus Christ.
VERSE 23. But before faith came.
The Apostle proceeds to explain the service which the Law is to render. Previously Paul had said that the Law was given to reveal the wrath and death of God upon all sinners. Although the Law kills, God brings good out of evil. He uses the Law to bring life. God saw that the universal illusion of self-righteousness could not be put down in any other way but by the Law. The Law dispels all self-illusions. It puts the fear of God in a man. Without this fear there can be no thirst for God's mercy. God accordingly uses the Law for a hammer to break up the illusion of self- righteousness, that we should despair of our own strength and efforts at self-justification.
VERSE 23. But before faith came, we were kept under the law, shut up unto the faith which should afterwards be revealed.
The Law is a prison to those who have not as yet obtained grace. No prisoner enjoys the confinement. He hates it. If he could he would smash the prison and find his freedom at all cost. As long as he stays in prison he refrains from evil deeds. Not because he wants to, but because he has to. The bars and the chains restrain him. He does not regret the crime that put him in jail. On the contrary, he is mighty sore that he cannot rob and kill as before. If he could escape he would go right back to robbing and killing.
The Law enforces good behavior, at least outwardly. We obey the Law because if we don't we will be punished. Our obedience is inspired by fear. We obey under duress and we do it resentfully. Now what kind of righteousness is this when we refrain from evil out of fear of punishment? Hence, the righteousness of the Law is at bottom nothing but love of sin and hatred of righteousness.
All the same, the Law accomplishes this much, that it will outwardly at least and to a certain extent repress vice and crime.
But the Law is also a spiritual prison, a veritable hell. When the Law begins to threaten a person with death and the eternal wrath of God, a man just cannot find any comfort at all. He cannot shake off at will the nightmare of terror which the Law stirs up in his conscience. Of this terror of the Law the Psalms furnish many glimpses.
The Law is a civil and a spiritual prison. And such it should be. For that the Law is intended. Only the confinement in the prison of the Law must not be unduly prolonged. It must come to an end. The freedom of faith must succeed the imprisonment of the Law.
Happy the person who knows how to utilize the Law so that it serves the purposes of grace and of faith. Unbelievers are ignorant of this happy knowledge. When Cain was first shut up in the prison of the Law he felt no pang at the fratricide he had committed. He thought he could pass it off as an incident with a shrug of the shoulder. "Am I my brother's keeper?" he answered God flippantly. But when he heard the ominous words, "What hast thou done? the voice of thy brother's blood crieth unto me from the ground," Cain began to feel his imprisonment. Did he know how to get out of prison? No. He failed to call the Gospel to his aid. He said: "My punishment is greater than I can bear." He could only think of the prison. He forgot that he was brought face to face with his crime so that he should hurry to God for mercy and for pardon. Cain remained in the prison of the Law and despaired.
As a stone prison proves a physical handicap, so the spiritual prison of the Law proves a chamber of torture. But this it should only be until faith be revealed. The silly conscience must be educated to this. Talk to your conscience. Say: "Sister, you are now in jail all right. But you don't have to stay there forever. It is written that we are 'shut up unto faith which should afterwards be revealed.' Christ will lead you to freedom. Do not despair like Cain, Saul, or Judas. They might have gone free if they had called Christ to their aid. Just take it easy, Sister Conscience. It's good for you to be locked up for a while. It will teach you to appreciate Christ."
How anybody can say that he by nature loves the Law is beyond me. The Law is a prison to be feared and hated. Any unconverted person who says he loves the Law is a liar. He does not know what he is talking about. We love the Law about as well as a murderer loves his gloomy cell, his straight-jacket, and the iron bars in front of him. How then can the Law justify us?
VERSE 23. Shut up unto the faith which should afterwards be revealed.
We know that Paul has reference to the time of Christ's coming. It was then that faith and the object of faith were fully revealed. But we may apply the historical fact to our inner life. When Christ came He abolished the Law and brought liberty and life to light. This He continues to do in the hearts of the believers. The Christian has a body in whose members, as Paul says, sin dwells and wars. I take sin to mean not only the deed but root, tree, fruit, and all. A Christian may perhaps not fall into the gross sins of murder, adultery, theft, but he is not free from impatience, complaints, hatreds, and blasphemy of God. As carnal lust is strong in a young man, in a man of full age the desire for glory, and in an old man covetousness, so impatience, doubt, and hatred of God often prevail in the hearts of sincere Christians. Examples of these sins may be garnered from the Psalms, Job, Jeremiah, and all the Sacred Scriptures.
Accordingly each Christian continues to experience in his heart times of the Law and times of the Gospel. The times of the Law are discernible by heaviness of heart, by a lively sense of sin, and a feeling of despair brought on by the Law. These periods of the Law will come again and again as long as we live. To mention my own case. There are many times when I find fault with God and am impatient with Him. The wrath and the judgment of God displease me, my wrath and impatience displease Him. Then is the season of the Law, when "the flesh lusteth against the Spirit, and the Spirit against the flesh."
The time of grace returns when the heart is enlivened by the promise of God's mercy. It soliloquizes: "Why art thou cast down, O my soul? and why art thou disquieted within me? Can you see nothing but law, sin, death, and hell? Is there no grace, no forgiveness, no joy, peace, life, heaven, no Christ and God? Trouble me no more, my soul. Hope in God who has not spared His own dear Son but has given Him into death for thy sins." When the Law carries things too far, say: "Mister Law, you are not the whole show. There are other and better things than you. They tell me to trust in the Lord."
There is a time for the Law and a time for grace. Let us study to be good timekeepers. It is not easy. Law and grace may be miles apart in essence, but in the heart, they are pretty close together. In the heart fear and trust, sin and grace, Law and Gospel cross paths continually.
Whether reason hears that justification before God is obtained by grace alone, it draws the inference that the Law is without value. The doctrine of the Law must therefore be studied carefully lest we either reject the Law altogether, or are tempted to attribute to the Law a capacity to save.
There are three ways in which the Law may be abused. First, by the self- righteous hypocrites who fancy that they can be justified by the Law. Secondly, by those who claim that Christian liberty exempts a Christian from the observance of the Law. "These," says Peter, "use their liberty for a cloak of maliciousness," and bring the name and the Gospel of Christ into ill repute. Thirdly, the Law is abused by those who do not understand that the Law is meant to drive us to Christ. When the Law is properly used its value cannot be too highly appraised. It will take me to Christ every time.
VERSE 24. Wherefore the law was our schoolmaster to bring us unto Christ.
This simile of the schoolmaster is striking. Schoolmasters are indispensable. But show me a pupil who loves his schoolmaster. How little love is lost upon them the Jews showed by their attitude toward Moses. They would have been glad to stone Moses to death. (Ex. 17:4.) You cannot expect anything else. How can a pupil love a teacher who frustrates his desires? And if the pupil disobeys, the schoolmaster whips him, and the pupil has to like it and even kiss the rod with which he was beaten. Do you think the schoolboy feels good about it? As soon as the teacher turns his back, the pupil breaks the rod and throws it into the fire. And if he were stronger than the teacher he would not take the beatings, but beat up the teacher. All the same, teachers are indispensable, otherwise the children would grow up without discipline, instruction, and training.
But how long are the scolding and the whippings of the schoolmaster to continue? Only for a time, until the boy has been trained to be a worthy heir of his father. No father wants his son to be whipped all the time. The discipline is to last until the boy has been trained to be his father's worthy successor.
The Law is such a schoolmaster. Not for always, but until we have been brought to Christ. The Law is not just another schoolmaster. The Law is a specialist to bring us to Christ. What would you think of a schoolmaster who could only torment and beat a child? Yet of such schoolmasters there were plenty in former times, regular bruisers. The Law is not that kind of a schoolmaster. It is not to torment us always. With its lashings it is only too anxious to drive us to Christ. The Law is like the good schoolmaster who trains his children to find pleasure in doing things they formerly detested.
VERSE 24. That we might be justified by faith.
The Law is not to teach us another Law. When a person feels the full force of the Law he is likely to think: I have transgressed all the commandments of God; I am guilty of eternal death. If God will spare me I will change and live right from now on. This natural but entirely wrong reaction to the Law has bred the many ceremonies and works devised to earn grace and remission of sins.
The Law means to enlarge my sins, to make me small, so that I may be justified by faith in Christ. Faith is neither law nor word; but confidence in Christ "who is the end of the law." How so is Christ the end of the Law? Not in this way that He replaced the old Law with new laws. Nor is Christ the end of the Law in a way that makes Him a hard judge who has to be bribed by works as the papists teach. Christ is the end or finish of the Law to all who believe in Him. The Law can no longer accuse or condemn them.
But what does the Law accomplish for those who have been justified by Christ? Paul answers this question next.
VERSE 25. But after that faith is come, we are no longer under a schoolmaster.
The Apostle declares that we are free from the Law. Christ fulfilled the Law for us. We may live in joy and safety under Christ. The trouble is, our flesh will not let us believe in Christ with all our heart. The fault lies not with Christ, but with us. Sin clings to us as long as we live and spoils our happiness in Christ. Hence, we are only partly free from the Law. "With the mind I myself serve the law of God; but with the flesh the law of sin." (Romans 7:25.)
As far as the conscience is concerned it may cheerfully ignore the Law. But because sin continues to dwell in the flesh, the Law waits around to molest our conscience. More and more, however, Christ increases our faith and in the measure in which our faith is increased, sin, Law, and flesh subside.
If anybody objects to the Gospel and the sacraments on the ground that Christ has taken away our sins once and for always, you will know what to answer. You will answer: Indeed, Christ has taken away my sins. But my flesh, the world, and the devil interfere with my faith. The little light of faith in my heart does not shine all over me at once. It is a gradual diffusion. In the meanwhile I console myself with the thought that eventually my flesh will be made perfect in the resurrection.
VERSE 26. For we are all the children of God by faith in Christ Jesus.
Paul as a true apostle of faith always has the word "faith" on the tip of his tongue. By faith, says he, we are the children of God. The Law cannot beget children of God. It cannot regenerate us. It can only remind us of the old birth by which we were born into the kingdom of the devil. The best the Law can do for us is to prepare us for a new birth through faith in Christ Jesus. Faith in Christ regenerates us into the children of God. St. John bears witness to this in his Gospel: "As many as received him, to them gave he power to become the sons of God, even to them that believe on his name." (John 1:12.) What tongue of man or angel can adequately extol the mercy of God toward us miserable sinners in that He adopted us for His own children and fellow-heirs with His Son by the simple means of faith in Christ Jesus!
VERSE 27. For as many of you as have been baptized into Christ have put on Christ.
To "put on Christ" may be understood in two ways, according to the Law and according to the Gospel. According to the Law as in Romans 13:14, "Put ye on the Lord Jesus Christ," which means to follow the example of Christ.
To put on Christ according to the Gospel means to clothe oneself with the righteousness, wisdom, power, life, and Spirit of Christ. By nature we are clad in the garb of Adam. This garb Paul likes to call "the old man." Before we can become the children of God this old man must be put off, as Paul says, Ephesians 4:29. The garment of Adam must come off like soiled clothes. Of course, it is not as simple as changing one's clothes. But God makes it simple. He clothes us with the righteousness of Christ by means of Baptism, as the Apostle says in this verse: "As many of you as have been baptized into Christ have put on Christ." With this change of garments a new birth, a new life stirs in us. New affections toward God spring up in the heart. New determinations affect our will. All this is to put on Christ according to the Gospel. Needless to say, when we have put on the robe of the righteousness of Christ we must not forget to put on also the mantle of the imitation of Christ.
VERSE 28. There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female; for ye are all one in Christ Jesus.
The list might be extended indefinitely: There is neither preacher nor hearer, neither teacher nor scholar, neither master nor servant, etc. In the matter of salvation, rank, learning, righteousness, influence count for nothing.
With this statement Paul deals a death blow to the Law. When a person has put on Christ nothing else matters. Whether a person is a Jew, a punctilious and circumcised observer of the Law of Moses, or whether a person is a noble and wise Greek does not matter. Circumstances, personal worth, character, achievements have no bearing upon justification. Before God they count for nothing. What counts is that we put on Christ.
Whether a servant performs his duties well; whether those who are in authority govern wisely; whether a man marries, provides for his family, and is an honest citizen; whether a woman is chaste, obedient to her husband, and a good mother: all these advantages do not qualify a person for salvation. These virtues are commendable, of course; but they do not count points for justification. All the best laws, ceremonies, religions, and deeds of the world cannot take away sin guilt, cannot dispatch death, cannot purchase life.
There is much disparity among men in the world, but there is no such disparity before God. "For all have sinned, and come short of the glory of God." (Romans 3:23.) Let the Jews, let the Greeks, let the whole world keep silent in the presence of God. Those who are justified are justified by Christ. Without faith in Christ the Jew with his laws, the monk with his holy orders, the Greek with his wisdom, the servant with his obedience, shall perish forever.
VERSE 28. For ye are all one in Christ Jesus.
There is much imparity among men in the world. And it is a good thing. If the woman would change places with the man, if the son would change places with the father, the servant with the master, nothing but confusion would result. In Christ, however, all are equal. We all have one and the same Gospel, "one faith, one baptism, one God and Father of all," one Christ and Savior of all. The Christ of Peter, Paul, and all the saints is our Christ. Paul can always be depended on to add the conditional clause, "In Christ Jesus." If we lose sight of Christ, we lose out.
VERSE 29. And if ye be Christ's, then are ye Abraham's seed, and heirs according to the promise.
"If ye be Christ's" means, if you believe in Christ. If you believe in Christ, then are you the children of Abraham indeed. Through our faith in Christ Abraham gains paternity over us and over the nations of the earth according to the promise: "In thy seed shall all the nations of the earth be blessed." Through faith we belong to Christ and Christ to us.
