Concerning Christian Liberty; with Letter of Martin Luther to Pope Leo X.

Although, as I have said, inwardly, and according to the spirit, a man is amply enough justified by faith, having all that he requires to have, except that this very faith and abundance ought to increase from day to day, even till the future life, still he remains in this mortal life upon earth, in which it is necessary that he should rule his own body and have intercourse with men. Here then works begin; here he must not take his ease; here he must give heed to exercise his body by fastings, watchings, labour, and other regular discipline, so that it may be subdued to the spirit, and obey and conform itself to the inner man and faith, and not rebel against them nor hinder them, as is its nature to do if it is not kept under. For the inner man, being conformed to God and created after the image of God through faith, rejoices and delights itself in Christ, in whom such blessings have been conferred on it, and hence has only this task before it: to serve God with joy and for nought in free love.

But in doing this he comes into collision with that contrary will in his own flesh, which is striving to serve the world and to seek its own gratification. This the spirit of faith cannot and will not bear, but applies itself with cheerfulness and zeal to keep it down and restrain it, as Paul says, "I delight in the law of God after the inward man; but I see another law in my members, warring against the law of my mind and bringing me into captivity to the law of sin" (Rom. vii. 22, 23), and again, "I keep under my body, and bring it unto subjection, lest that by any means, when I have preached to others, I myself should be a castaway" (1 Cor. ix. 27), and "They that are Christ's have crucified the flesh, with the affections and lusts" (Gal. v. 24).

These works, however, must not be done with any notion that by them a man can be justified before God—for faith, which alone is righteousness before God, will not bear with this false notion—but solely with this purpose: that the body may be brought into subjection, and be purified from its evil lusts, so that our eyes may be turned only to purging away those lusts. For when the soul has been cleansed by faith and made to love God, it would have all things to be cleansed in like manner, and especially its own body, so that all things might unite with it in the love and praise of God. Thus it comes that, from the requirements of his own body, a man cannot take his ease, but is compelled on its account to do many good works, that he may bring it into subjection. Yet these works are not the means of his justification before God; he does them out of disinterested love to the service of God; looking to no other end than to do what is well-pleasing to Him whom he desires to obey most dutifully in all things.

On this principle every man may easily instruct himself in what measure, and with what distinctions, he ought to chasten his own body. He will fast, watch, and labour, just as much as he sees to suffice for keeping down the wantonness and concupiscence of the body. But those who pretend to be justified by works are looking, not to the mortification of their lusts, but only to the works themselves; thinking that, if they can accomplish as many works and as great ones as possible, all is well with them, and they are justified. Sometimes they even injure their brain, and extinguish nature, or at least make it useless. This is enormous folly, and ignorance of Christian life and faith, when a man seeks, without faith, to be justified and saved by works.

To make what we have said more easily understood, let us set it forth under a figure. The works of a Christian man, who is justified and saved by his faith out of the pure and unbought mercy of God, ought to be regarded in the same light as would have been those of Adam and Eve in paradise and of all their posterity if they had not sinned. Of them it is said, "The Lord God took the man and put him into the garden of Eden to dress it and to keep it" (Gen. ii. 15). Now Adam had been created by God just and righteous, so that he could not have needed to be justified and made righteous by keeping the garden and working in it; but, that he might not be unemployed, God gave him the business of keeping and cultivating paradise. These would have indeed been works of perfect freedom, being done for no object but that of pleasing God, and not in order to obtain justification, which he already had to the full, and which would have been innate in us all.

So it is with the works of a believer. Being by his faith replaced afresh in paradise and created anew, he does not need works for his justification, but that he may not be idle, but may exercise his own body and preserve it. His works are to be done freely, with the sole object of pleasing God. Only we are not yet fully created anew in perfect faith and love; these require to be increased, not, however, through works, but through themselves.

A bishop, when he consecrates a church, confirms children, or performs any other duty of his office, is not consecrated as bishop by these works; nay, unless he had been previously consecrated as bishop, not one of those works would have any validity; they would be foolish, childish, and ridiculous. Thus a Christian, being consecrated by his faith, does good works; but he is not by these works made a more sacred person, or more a Christian. That is the effect of faith alone; nay, unless he were previously a believer and a Christian, none of his works would have any value at all; they would really be impious and damnable sins.

True, then, are these two sayings: "Good works do not make a good man, but a good man does good works"; "Bad works do not make a bad man, but a bad man does bad works." Thus it is always necessary that the substance or person should be good before any good works can be done, and that good works should follow and proceed from a good person. As Christ says, "A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit" (Matt. vii. 18). Now it is clear that the fruit does not bear the tree, nor does the tree grow on the fruit; but, on the contrary, the trees bear the fruit, and the fruit grows on the trees.

As then trees must exist before their fruit, and as the fruit does not make the tree either good or bad, but on the contrary, a tree of either kind produces fruit of the same kind, so must first the person of the man be good or bad before he can do either a good or a bad work; and his works do not make him bad or good, but he himself makes his works either bad or good.

We may see the same thing in all handicrafts. A bad or good house does not make a bad or good builder, but a good or bad builder makes a good or bad house. And in general no work makes the workman such as it is itself; but the workman makes the work such as he is himself. Such is the case, too, with the works of men. Such as the man himself is, whether in faith or in unbelief, such is his work: good if it be done in faith; bad if in unbelief. But the converse is not true that, such as the work is, such the man becomes in faith or in unbelief. For as works do not make a believing man, so neither do they make a justified man; but faith, as it makes a man a believer and justified, so also it makes his works good.

Since then works justify no man, but a man must be justified before he can do any good work, it is most evident that it is faith alone which, by the mere mercy of God through Christ, and by means of His word, can worthily and sufficiently justify and save the person; and that a Christian man needs no work, no law, for his salvation; for by faith he is free from all law, and in perfect freedom does gratuitously all that he does, seeking nothing either of profit or of salvation—since by the grace of God he is already saved and rich in all things through his faith—but solely that which is well-pleasing to God.

So, too, no good work can profit an unbeliever to justification and salvation; and, on the other hand, no evil work makes him an evil and condemned person, but that unbelief, which makes the person and the tree bad, makes his works evil and condemned. Wherefore, when any man is made good or bad, this does not arise from his works, but from his faith or unbelief, as the wise man says, "The beginning of sin is to fall away from God"; that is, not to believe. Paul says, "He that cometh to God must believe" (Heb. xi. 6); and Christ says the same thing: "Either make the tree good and his fruit good; or else make the tree corrupt, and his fruit corrupt" (Matt. xii. 33),—as much as to say, He who wishes to have good fruit will begin with the tree, and plant a good one; even so he who wishes to do good works must begin, not by working, but by believing, since it is this which makes the person good. For nothing makes the person good but faith, nor bad but unbelief.

It is certainly true that, in the sight of men, a man becomes good or evil by his works; but here "becoming" means that it is thus shown and recognised who is good or evil, as Christ says, "By their fruits ye shall know them" (Matt. vii. 20). But all this stops at appearances and externals; and in this matter very many deceive themselves, when they presume to write and teach that we are to be justified by good works, and meanwhile make no mention even of faith, walking in their own ways, ever deceived and deceiving, going from bad to worse, blind leaders of the blind, wearying themselves with many works, and yet never attaining to true righteousness, of whom Paul says, "Having a form of godliness, but denying the power thereof, ever learning and never able to come to the knowledge of the truth" (2 Tim. iii. 5, 7).

He then who does not wish to go astray, with these blind ones, must look further than to the works of the law or the doctrine of works; nay, must turn away his sight from works, and look to the person, and to the manner in which it may be justified. Now it is justified and saved, not by works or laws, but by the word of God—that is, by the promise of His grace—so that the glory may be to the Divine majesty, which has saved us who believe, not by works of righteousness which we have done, but according to His mercy, by the word of His grace.

From all this it is easy to perceive on what principle good works are to be cast aside or embraced, and by what rule all teachings put forth concerning works are to be understood. For if works are brought forward as grounds of justification, and are done under the false persuasion that we can pretend to be justified by them, they lay on us the yoke of necessity, and extinguish liberty along with faith, and by this very addition to their use they become no longer good, but really worthy of condemnation. For such works are not free, but blaspheme the grace of God, to which alone it belongs to justify and save through faith. Works cannot accomplish this, and yet, with impious presumption, through our folly, they take it on themselves to do so; and thus break in with violence upon the office and glory of grace.

We do not then reject good works; nay, we embrace them and teach them in the highest degree. It is not on their own account that we condemn them, but on account of this impious addition to them and the perverse notion of seeking justification by them. These things cause them to be only good in outward show, but in reality not good, since by them men are deceived and deceive others, like ravening wolves in sheep's clothing.

Now this leviathan, this perverted notion about works, is invincible when sincere faith is wanting. For those sanctified doers of works cannot but hold it till faith, which destroys it, comes and reigns in the heart. Nature cannot expel it by her own power; nay, cannot even see it for what it is, but considers it as a most holy will. And when custom steps in besides, and strengthens this pravity of nature, as has happened by means of impious teachers, then the evil is incurable, and leads astray multitudes to irreparable ruin. Therefore, though it is good to preach and write about penitence, confession, and satisfaction, yet if we stop there, and do not go on to teach faith, such teaching is without doubt deceitful and devilish. For Christ, speaking by His servant John, not only said, "Repent ye," but added, "for the kingdom of heaven is at hand" (Matt. iii. 2).

For not one word of God only, but both, should be preached; new and old things should be brought out of the treasury, as well the voice of the law as the word of grace. The voice of the law should be brought forward, that men may be terrified and brought to a knowledge of their sins, and thence be converted to penitence and to a better manner of life. But we must not stop here; that would be to wound only and not to bind up, to strike and not to heal, to kill and not to make alive, to bring down to hell and not to bring back, to humble and not to exalt. Therefore the word of grace and of the promised remission of sin must also be preached, in order to teach and set up faith, since without that word contrition, penitence, and all other duties, are performed and taught in vain.

There still remain, it is true, preachers of repentance and grace, but they do not explain the law and the promises of God to such an end, and in such a spirit, that men may learn whence repentance and grace are to come. For repentance comes from the law of God, but faith or grace from the promises of God, as it is said, "Faith cometh by hearing, and hearing by the word of God" (Rom. x. 17), whence it comes that a man, when humbled and brought to the knowledge of himself by the threatenings and terrors of the law, is consoled and raised up by faith in the Divine promise. Thus "weeping may endure for a night, but joy cometh in the morning" (Psalm xxx. 5). Thus much we say concerning works in general, and also concerning those which the Christian practises with regard to his own body.

Lastly, we will speak also of those works which he performs towards his neighbour. For man does not live for himself alone in this mortal body, in order to work on its account, but also for all men on earth; nay, he lives only for others, and not for himself. For it is to this end that he brings his own body into subjection, that he may be able to serve others more sincerely and more freely, as Paul says, "None of us liveth to himself, and no man dieth to himself. For whether we live, we live unto the Lord; and whether we die, we die unto the Lord" (Rom. xiv. 7, 8). Thus it is impossible that he should take his ease in this life, and not work for the good of his neighbours, since he must needs speak, act, and converse among men, just as Christ was made in the likeness of men and found in fashion as a man, and had His conversation among men.

Yet a Christian has need of none of these things for justification and salvation, but in all his works he ought to entertain this view and look only to this object—that he may serve and be useful to others in all that he does; having nothing before his eyes but the necessities and the advantage of his neighbour. Thus the Apostle commands us to work with our own hands, that we may have to give to those that need. He might have said, that we may support ourselves; but he tells us to give to those that need. It is the part of a Christian to take care of his own body for the very purpose that, by its soundness and well-being, he may be enabled to labour, and to acquire and preserve property, for the aid of those who are in want, that thus the stronger member may serve the weaker member, and we may be children of God, thoughtful and busy one for another, bearing one another's burdens, and so fulfilling the law of Christ.

Here is the truly Christian life, here is faith really working by love, when a man applies himself with joy and love to the works of that freest servitude in which he serves others voluntarily and for nought, himself abundantly satisfied in the fulness and riches of his own faith.

Thus, when Paul had taught the Philippians how they had been made rich by that faith in Christ in which they had obtained all things, he teaches them further in these words: "If there be therefore any consolation in Christ, if any comfort of love, if any fellowship of the Spirit, if any bowels and mercies, fulfil ye my joy, that ye be like-minded, having the same love, being of one accord, of one mind. Let nothing be done through strife or vainglory; but in lowliness of mind let each esteem other better than themselves. Look not every man on his own things, but every man also on the things of others" (Phil. ii. 1-4).

In this we see clearly that the Apostle lays down this rule for a Christian life: that all our works should be directed to the advantage of others, since every Christian has such abundance through his faith that all his other works and his whole life remain over and above wherewith to serve and benefit his neighbour of spontaneous goodwill.

To this end he brings forward Christ as an example, saying, "Let this mind be in you, which was also in Christ Jesus, who, being in the form of God, thought it not robbery to be equal with God, but made Himself of no reputation, and took upon Him the form of a servant, and was made in the likeness of men; and being found in fashion as a man, He humbled Himself, and became obedient unto death" (Phil. ii. 5-8). This most wholesome saying of the Apostle has been darkened to us by men who, totally misunderstanding the expressions "form of God," "form of a servant," "fashion," "likeness of men," have transferred them to the natures of Godhead and manhood. Paul's meaning is this: Christ, when He was full of the form of God and abounded in all good things, so that He had no need of works or sufferings to be just and saved—for all these things He had from the very beginning—yet was not puffed up with these things, and did not raise Himself above us and arrogate to Himself power over us, though He might lawfully have done so, but, on the contrary, so acted in labouring, working, suffering, and dying, as to be like the rest of men, and no otherwise than a man in fashion and in conduct, as if He were in want of all things and had nothing of the form of God; and yet all this He did for our sakes, that He might serve us, and that all the works He should do under that form of a servant might become ours.
