Now, since the being and nature of man cannot for an instant be without doing or not doing something, enduring or running away from something (for, as we see, life never rests), let him who will be pious and filled with good works, begin and in all his life and works at all times exercise himself in this faith; let him learn to do and to leave undone all things in such continual faith; then will he find how much work he has to do, and how completely all things are included in faith; how he dare never grow idle, because his very idling must be the exercise and work of faith. In brief, nothing can be in or about us and nothing can happen to us but that it must be good and meritorious, if we believe (as we ought) that all things please God. So says St. Paul: "Dear brethren, all that ye do, whether ye eat or drink, do all in the Name of Jesus Christ, our Lord." Now it cannot be done in this Name except it be done in this faith. Likewise, Romans vii: "We know that all things work together for good to the saints of God."
Therefore, when some say that good works are forbidden when we preach faith alone, it is as if I said to a sick man: "If you had health, you would have the use of all your limbs; but without health, the works of all your limbs are nothing"; and he wanted to infer that I had forbidden the works of all his limbs; whereas, on the contrary, I meant that he must first have health, which will work all the works of all the members. So faith also must be in all works the master-workman and captain, or they are nothing at all.
XIV. You might say: "Why then do we have so many laws of the Church and of the State, and many ceremonies of churches, monastic houses, holy places, which urge and tempt men to good works, if faith does all things through the First Commandment?" I answer: Simply because we do not all have faith or do not heed it. If every man had faith, we would need no more laws, but every one would of himself at all times do good works, as his confidence in God teaches him.
But now there are four kinds of men: the first, just mentioned, who need no law, of whom St. Paul says, I. Timothy i, "The law is not made for a righteous man," that is, for the believer, but believers of themselves do what they know and can do, only because they firmly trust that God's favor and grace rests upon them in all things. The second class want to abuse this freedom, put a false confidence in it, and grow lazy; of whom St. Peter says, I. Peter ii, "Ye shall live as free men, but not using your liberty for a cloak of maliciousness," as if he said: The freedom of faith does not permit sins, nor will it cover them, but it sets us free to do all manner of good works and to endure all things as they happen to us, so that a man is not bound only to one work or to a few. So also St. Paul, Galatians v: "Use not your liberty for an occasion to the flesh." Such men must be urged by laws and hemmed in by teaching and exhortation. The third class are wicked men, always ready for sins; these must be constrained by spiritual and temporal laws, like wild horses and dogs, and where this does not help, they must be put to death by the worldly sword, as St. Paul says, Romans xiii: "The worldly ruler bears the sword, and serves God with it, not as a terror to the good, but to the evil." The fourth class, who are still lusty, and childish in their understanding of faith and of the spiritual life, must be coaxed like young children and tempted with external, definite and prescribed decorations, with reading, praying, fasting, singing, adorning of churches, organ playing, and such other things as are commanded and observed in monastic houses and churches, until they also learn to know the faith. Although there is great danger here, when the rulers, as is now, alas! the case, busy themselves with and insist upon such ceremonies and external works as if they were the true works, and neglect faith, which they ought always to teach along with these works, just as a mother gives her child other food along with the milk, until the child can eat the strong food by itself.
XV. Since, then, we are not all alike, we must tolerate such people, share their observances and burdens, and not despise them, but teach them the true way of faith. So St. Paul teaches, Romans xiv: "Him that is weak in the faith receive ye, to teach him." And so he did himself, I. Corinthians ix: "To them that are under the law, I became as under the law, although I was not under the law." And Christ, Matthew xvii, when He was asked to pay tribute, which He was not obligated to pay, argues with St. Peter, whether the children of kings must give tribute, or only other people. St. Peter answers: "Only other people." Christ said: "Then are the children of kings free; notwithstanding, lest we should offend them, go thou to the sea, and cast an hook, and take up the fish that first cometh up; and in his mouth thou shalt find a piece of money; take that and give it for me and thee."
Here we see that all works and things are free to a Christian through his faith; and yet, because the others do not yet believe, he observes and bears with them what he is not obligated to do. But this he does freely, for he is certain that this is pleasing to God, and he does it willingly, accepts it as any other free work which comes to his hand without his choice, because he desires and seeks no more than that he may in his faith do works to please God.
But since in this discourse we have undertaken to teach what righteous and good works are, and are now speaking of the highest work, it is clear that we do not speak of the second, third and fourth classes of men, but of the first, into whose likeness all the others are to grow, and until they do so the first class must endure and instruct them. Therefore we must not despise, as if they were hopeless, these men of weak faith, who would gladly do right and learn, and yet cannot understand because of the ceremonies to which they cling; we must rather blame their ignorant, blind teachers, who have never taught them the faith, and have led them so deeply into works. They must be gently and gradually led back again to faith, as a sick man is treated, and must be allowed for a time, for their conscience sake, to cling to some works and do them as necessary to salvation, so long as they rightly grasp the faith; lest if we try to tear them out so suddenly, their weak consciences be quite shattered and confused, and retain neither faith nor works. But the hardheaded, who, hardened in their works, give no heed to what is said of faith, and fight against it, these we must, as Christ did and taught, let go their way, that the blind may lead the blind.
XVI. But you say: How can I trust surely that all my works are pleasing to God, when at times I fall, and talk, eat, drink and sleep too much, or otherwise transgress, as I cannot help doing? Answer: This question shows that you still regard faith as a work among other works, and do not set it above all works. For it is the highest work for this very reason, because it remains and blots out these daily sins by not doubting that God is so kind to you as to wink at such daily transgression and weakness. Aye, even if a deadly sin should occur (which, however, never or rarely happens to those who live in faith and trust toward God), yet faith rises again and does not doubt that its sin is already gone; as it is written I. John ii: "My little children, these things I write unto you, that ye sin not. And if any man sin, we have an Advocate with God the Father, Jesus Christ, Who is the propitiation of all our sins." And Wisdom xv: "For if we sin, we are Thine, knowing Thy power." And Proverbs xxiv: "For a just man falleth seven times, and riseth up again." Yes, this confidence and faith must be so high and strong that the man knows that all his life and works are nothing but damnable sins before God's judgment, as it is written, Psalm cxliii: "In thy sight shall no man living be justified"; and he must entirely despair of his works, believing that they cannot be good except through this faith, which looks for no judgment, but only for pure grace, favor, kindness and mercy, like David, Psalm xxvi: "Thy loving kindness is ever before mine eyes, and I have trusted in Thy truth"; Psalm iv: "The light of Thy countenance is lift up upon us (that is, the knowledge of Thy grace through faith), and thereby hast Thou put gladness in my heart"; for as faith trusts, so it receives.
See, thus are works forgiven, are without guilt and are good, not by their own nature, but by the mercy and grace of God because of the faith which trusts on the mercy of God. Therefore we must fear because of the works, but comfort ourselves because of the grace of God, as it is written, Psalm cxlvii: "The Lord taketh pleasure in them that I fear Him, in those that hope in His mercy." So we pray with perfect confidence: "Our Father," and yet petition: "Forgive us our trespasses"; we are children and yet sinners; are acceptable and yet do not do enough; and all this is the work of faith, firmly grounded in God's grace.
XVII. But if you ask, where the faith and the confidence can be found and whence they come, this it is certainly most necessary to know. First: Without doubt faith does not come from your works or merit, but alone from Jesus Christ, and is freely promised and given; as St. Paul writes, Romans v: "God commendeth His love to us as exceeding sweet and kindly, in that, while we were yet sinners, Christ died for us"; as if he said: "Ought not this give us a strong unconquerable confidence, that before we prayed or cared for it, yes, while we still continually walked in sins, Christ dies for our sin?" St. Paul concludes: "If while we were yet sinners Christ died for us, how much more then, being justified by His blood, shall we be saved from wrath through Him; and if, when we were enemies, we were reconciled to God by the death of His Son, much more, being reconciled, shall we be saved by His life."
