28. The substance of the matter is this: When all the commandments have been put together, when their message receives every particle of praise to which it is entitled, it is still a mere letter. That is, teaching not put into practice. By "letter" is signified all manner of law, doctrine and message, which goes no farther than the oral or written word, which consists only of the powerless letter. To illustrate: A law promulgated by a prince or the authorities of a city, if not enforced, remains merely an open letter, which makes a demand indeed, but ineffectually. Similarly, God's Law, although a teaching of supreme authority and the eternal will of God, must suffer itself to become a mere empty letter or husk. Without a quickening heart, and devoid of fruit, the Law is powerless to effect life and salvation. It may well be called a veritable table of omissions (Lass-tafel); that is, it is a written enumeration, not of duties performed but of duties cast aside. In the languages of the world, it is a royal edict which remains unobserved and unperformed. In this light St. Augustine understood the Law. He says, commenting on Psalm 17, "What is Law without grace but a letter without spirit?" Human nature, without the aid of Christ and his grace, cannot keep it.
29. Again, Paul in terming the Gospel a "ministration of the spirit" would call attention to its power to produce in the hearts of men an effect wholly different from that of the Law: it is accompanied by the Holy Spirit and it creates a new heart. Man, driven into fear and anxiety by the preaching of the Law, hears this Gospel message, which, instead of reminding him of God's demands, tells him what God has done for him. It points not to man's works, but to the works of Christ, and bids him confidently believe that for the sake of his Son God will forgive his sins and accept him as his child. And this message, when received in faith, immediately cheers and comforts the heart. The heart will no longer flee from God; rather it turns to him. Finding grace with God and experiencing his mercy, the heart feels drawn to him. It commences to call upon him and to treat and revere him as its beloved God. In proportion as such faith and solace grow, also love for the commandments will grow and obedience to them will be man's delight. Therefore, God would have his Gospel message urged unceasingly as the means of awakening man's heart to discern his state and recall the great grace and lovingkindness of God, with the result that the power of the Holy Spirit is increased constantly. Note, no influence of the Law, no work of man is present here. The force is a new and heavenly one—the power of the Holy Spirit. He impresses upon the heart Christ and his works, making of it a true book which does not consist in the tracery of mere letters and words, but in true life and action.
30. God promised of old, in Joel 2, 28 and other passages, to give the Spirit through the new message, the Gospel. And he has verified his promise by public manifestations in connection with the preaching of that Gospel, as on the day of Pentecost and again later. When the apostles, Peter and others, began to preach, the Holy Spirit descended visibly from heaven upon their hearts. Acts 8, 17; 10, 44. Up to that time, throughout the period the Law was preached, no one had heard or seen such manifestation. The fact could not but be grasped that this was a vastly different message from that of the Law when such mighty results followed in its train. And yet its substance was no more than what Paul declared (Acts 13, 38-39): "Through this man is proclaimed unto you remission of sins: and by him every one that believeth is justified from all things, from which ye could not be justified by the law of Moses."
31. In this teaching you see no more the empty letters, the valueless husks or shells, of the Law, which unceasingly enjoins, "This thou shalt do and observe," and ever in vain. You see instead the true kernel and power which confers Christ and the fullness of His Spirit. In consequence, men heartily believe the message of the Gospel and enjoy its riches. They are accounted as having fulfilled the Ten Commandments. John says (Jn 1, 16-17): "Of his fullness we all received, and grace for grace. For the Law was given through Moses; grace and truth came through Jesus Christ." John's thought is: The Law has indeed been given by Moses, but what avails that fact? To be sure, it is a noble doctrine and portrays a beautiful and instructive picture of man's duty to God and all mankind; it is really excellent as to the letter. Yet it remains empty; it does not enter into the heart. Therefore it is called "law," nor can it become aught else, so long as nothing more is given.
CHRIST SUPERSEDES MOSES.
Before there can be fulfilment, another than Moses must come, bringing another doctrine. Instead of a law enjoined, there must be grace and truth revealed. For to enjoin a command and to embody the truth* are two different things; just as teaching and doing differ. Moses, it is true, teaches the doctrine of the Law, so far as exposition is concerned, but he can neither fulfil it himself nor give others the ability to do so. That it might be fulfilled, God's Son had to come with his fullness; he has fulfilled the Law for himself and it is he who communicates to our empty heart the power to attain to the same fullness.
* Es ist zweirlei, Gesetz geben, und, Wahrheit werden.
This becomes possible when we receive grace for grace, that is, when we come to the enjoyment of Christ, and for the sake of him who enjoys with God fullness of grace, although our own obedience to the Law is still imperfect. Being possessed of solace and grace, we receive by his power the Holy Spirit also, so that, instead of harboring mere empty letters within us, we come to the truth and begin to fulfil God's Law, in such a way, however, that we draw from his fullness and drink from that as a fountain.
CHRIST THE SOURCE OF LIFE GREATER THAN ADAM THE SOURCE OF DEATH.
32. Paul gives us the same thought in Romans 5, 17-18, where he compares Adam and Christ. Adam, he says, by his disobedience in Paradise, became the source of sin and death in the world; by the sin of this one man, condemnation passed upon all men. But on the other hand, Christ, by his obedience and righteousness, has become for us the abundant source wherefrom all may obtain righteousness and the power of obedience. And with respect to the latter source, it is far richer and more abundant than the former. While by the single sin of one man, sin and death passed upon all men, to wax still more powerful with the advent of the Law, of such surpassing strength and greatness, on the other hand, is the grace and bounty which we have in Christ that it not only washes away the particular sin of the one man Adam, which, until Christ came, overwhelmed all men in death, but overwhelms and blots out all sin whatever. Thus they who receive his fullness of grace and bounty unto righteousness are, according to Paul, lords of life through Jesus Christ alone.
