Collected Works of Martin Luther

by Martin Luther

  But why does he say then, purify your souls? He is well aware that the desires of the flesh remain with us after baptism, even to the grave. Therefore it is not enough that a person should refrain from works and remain pure outwardly, while he permits evil lusts to cleave to his heart, but must thereafter beware that the soul be pure, as well as whatever proceeds out of the heart, and that the soul be opposed to these wicked lusts and desires, and continually contend therewith, until it is free from their power.

  And here he adjoins an excellent provision: that we should purify our souls,* through obedience to the truth in the Spirit. Much has been preached on chastity, and many books have been composed on the subject. They have said, we should fast for so long a time, we should not eat flesh, we should not drink wine, etc., that we may be free from temptation. These things may perhaps have aided somewhat to that end, but it has not been enough, it has not subdued lust.

  * Make them chaste.

  So St. Jerome writes of himself, that he had mortified his body to such an extent that he had become like a Moor; still it had been of no avail, and he had dreamed of being at Rome at a revelry among harlots.

  St. Bernard also subjected himself to such austerities, and so mortified his body that it became offensive, as I said above. They endured severe temptation, and purposed thus to subdue it by external methods. But since it is external, it is only an outward plaster, with no inward application. So that it does not suffice to subdue lust.

  But here St. Peter has prescribed an appropriate remedy, — namely, obedience to truth in the Spirit, as Scripture also has done in other places, — as Isaiah xi.: “Faith shall be the girdle of his reins.” This is the true plaster that girds the reins, for it must proceed from within outward, not from without inward. For it has penetrated into the flesh and blood, the marrow and other parts of the living system; it is not outward in the dress or clothing. Therefore it is not to be expected that we should subdue lust with outward things; we may weaken the body and destroy it with fastings and labors, but the evil lusts are not thereby banished; yet faith can subdue them, and guard them, that they shall be compelled to give the Spirit place.

  So likewise speaks the prophet Zachariah, ix., of the wine which Christ has, whereby the pure grow, and of which he gives them to drink. Other wine usually invites to wicked lust, but this wine, — that is, the Gospel, — subdues it, and makes the heart chaste. This is what St. Peter speaks of when any one heartily embraces the truth, and is obedient to it in spirit. This is the true help and the most powerful remedy for it, since you will find none which can still all evil thoughts like it; for if this enters our hearts, evil inclinations quickly leave; let whoever will try it, he shall find it true, and whoever has tried it, knows it well; but the devil lets no one easily attain it, and comprehend the word of God so as to delight in it; for he well knows how powerful it is to subdue evil lusts and thoughts.

  St. Peter, therefore, would here say, if you would remain chaste, then must you render obedience to the truth in the Spirit, that is, — we must not only read and hear the word of God, but apprehend it in our hearts. Therefore it is not enough that a man should preach or hear the Gospel once, but he must ever press after it and persevere; for such grace does the word possess, that the more we taste it the more delightful it is; although there is, throughout, one and the same doctrine of faith, yet it cannot be listened to too much where the heart is not wanton and untamed.

  To unfeigned love of the brethren. To what end, then, are we to live a chastely holy life? In order that we may be saved thereby? No! but in order that we may be useful to our neighbor. What am I to do that I may restrain my sin? I am to have obedience to the truth in the Spirit. But why am I to restrain it? In order that I may be of service to others, for I must first control my body and the flesh by the Spirit, and thus I can afterward be of service to others. — It follows further:

  And have fervent love toward one another out of pure hearts. The Apostles Peter and Paul distinguish brotherly love, and love in general, from one another. Brotherhood is, that Christians should dwell altogether as brethren, and make no distinctions between themselves. For since we all have a common Christ, one baptism, one faith, one treasure, I am no better than thou; that which thou hast, I have also, and I am just as rich as thou. The treasure is the same, except that I may have it in a better shape than thou, since I may have it lying in gold, but thou in a poor garment. Therefore as we have the grace of Christ and all spiritual blessings in common, so should we also hold body and life, property and honor, in common, that one should be of service to another in all things.

  Here he speaks plainly: in unfeigned brotherly love. The Apostles love to make use of the word, but have clearly perceived that were we called Christians and brethren universally one with another, it would be false, a feigned or imagined thing, and would be only hypocrisy. We have many brotherhoods set up in the world, but they are vain deceptions and corruptions, which the devil has devised and brought into the world, which are only antagonist to the true faith and to genuine brotherly love. Christ is mine as well as St. Bernard’s; thine as well as St. Francis’; if one therefore should come to you and say, I shall go to heaven if I belong to this or that brotherhood, then tell him that he is deceived; for Christ cannot suffer, and will not allow any other than the common brotherhood, which we all have one with another; yet you come here, you fool, and will set up one of your own. This I will readily permit, that they be set up, not to help the soul, but as some one’s endowment, and thus serve as a fund from which they who need shall be helped.

  Thus we all of us, as Christians, have attained a brotherhood in baptism, whereof no saint possesses more than I or you. For just as costly as that one was purchased, at the same price was I also purchased. God has devoted as much toward me as to the greatest saint, except that he may have employed the treasure better, and may have a stronger faith than I.

  But love is greater than brotherhood, for it extends even to our enemies, and especially to those who are not worthy of love. For as faith performs its work where it sees nothing, so also should love see nothing, and there especially exercise its office where there appears nothing lovely, but only disaffection and hostility. Where there is nothing that pleases me I should the more seek to be pleased. And this spirit should go forth fervently, says St. Peter, from the whole heart, just as God loved us when we were not worthy of love. — Now follows further:

  As those who have been born again. Again we should do this, because we are not what we were before (he says), but have become new creatures. This has not come to pass through works, but is a consequence of the new birth. For thou canst not make the new man, but he must grow, or be born; as a husbandman cannot make a tree, but it must grow, itself, out of the earth, and as we certainly do not become the children of Adam, except as we are born and derive sin from our parents. So here it cannot come to pass through works that we should become the children of God, but we must also experience the new birth. This, therefore, is what the Apostle would say: since ye then have become new creatures, ye should conduct yourselves otherwise than ye did, and lead a new life. As ye before lived in hate, ye are now to walk in love — in all respects the reverse. But how has the new birth taken place? This, also, follows:

  V. 23. Not of corruptible, but of incorruptible seed, even of the living word of God which endures for ever. Through a seed are we born again, for nothing grows as we see otherwise than through seed. Did the old birth spring from a seed? then must the new birth also spring from a seed. But what is this seed? Not flesh and blood! What then? It is not corruptible, but an eternal word. It is, moreover, that whereon we live, — food and nourishment. But especially is it the seed whereby we are born again, as he here says.

  But how does this take place? After this manner: God lets the word — the Gospel — go forth, and the seed falls in the hearts of men, and wherever it fastens on the heart the Holy Spirit is present, and makes a new man; then the man becomes another, of other thoughts
, of other words and works. Thus you are entirely changed. All that you before avoided you now seek out, and what you before sought after that you fly from. In respect to the birth of the body, it is the case that when conception takes place the seed is changed, so that it is seed no longer. But this is a seed which cannot be changed; it remains for ever; it changes me, so that I am transformed in it, and whatever is evil in me passes away from my nature. Therefore it is indeed a wonderful birth, and of extraordinary seed. — Now St. Peter says, further:

  V. 24, 25. For all flesh is grass, and all the glory of man like the flower of grass; the grass withereth, and the flower thereof falleth away, but the word of the Lord endureth for ever. This passage is taken from the prophet Isaiah, xl., where the prophet speaks in this manner: “Cry! what shall I cry? Cry thus: all flesh is grass, and all its glory like a flower of the field; the grass withereth and the flower falleth away, but the word of God endureth for ever.” These words St. Peter introduces here; for this is, as I have said, a rich epistle, and well spiced with Scripture.

  Thus speaks the Scripture, then: The word of God endures for ever. What is flesh and blood is corruptible, like the grass which is yet green, so that it blooms; so whatever is rich, strong, wise and fair, and thus is flourishing (which all belongs to the bloom), yet you observe its bloom wither; what was young and vigorous will become old and ugly; what is rich will become poor, and the like. And all must fall by the word of God. But this seed cannot perish. — Now Peter concludes:

  This is the word which is preached unto you. As though he would say, ye are not to look far in order to reach the word of God; ye have it before your eyes; the word is that which we preach; therewith may you subdue all evil lusts. You are not to seek it from afar; you have nothing more to do than fully to apprehend it when it is preached. For it is so near us that we may hear it, as Moses also says, in Deut. xxx.: “The word that I command you is not far from thee, that thou must go therefor far away; ascend into heaven or go beyond the sea, but it is near thee, even in thy mouth and in thy heart.” It is indeed soon spoken and heard. But if it enters our hearts it cannot die or perish, and will not suffer you to perish; as long as you cleave to it, it will cleave to you.

  As when I hear that Jesus Christ died to take away my sins, and has purchased heaven for me, and bestows upon me all that He has, then I hear the Gospel; the word quickly is gone if some one preaches it, but if it falls into the heart and is apprehended by faith, it can never pass away. This truth no creature can overthrow; the clearest reasoning avails nothing against it; and if I too would strike the devil while I am in his jaws, and am able to lay hold on this, I must oppose him from this and abide fast by the word. Therefore he well says, ye must look for no other Gospel than that which we have preached to you.

  So St. Paul also says, in the first part of the Epistle to the Romans: “I am not ashamed of the Gospel, for it is the power of God which saves all that believe in it.” The word is a divine and eternal power; for although the voice or speech is soon gone, yet the substance remains, — that is, the sense, the truth, which is conveyed by the voice. As when I put a cup to my mouth in which wine is contained, I swallow the wine, although I do not thrust the cup down my throat.

  So likewise is the word which the voice conveys; it falls into our hearts and lives, while the voice remains without and passes away. Therefore it is indeed a divine power; yea, it is God Himself. For thus He speaks to Moses, Exodus iv.: “I will be in thy mouth;” and Ps. lxxx.: “Open thy mouth wide, proclaim glad tidings; say thou art hungry, I will satisfy thee, I will presently speak to thee comfortable things.”

  So, also, in John xiv., Christ says: “I am the way, the truth, and the life.” Whoever confides in this is born of God; so that this seed of our Lord is itself divine. All this goes to teach us that we cannot be helped by works. Although the word is a small matter, and seems as nothing while it proceeds out of the mouth, yet is there such an immense power in it that it makes those who confide in it the children of God. John i. Thus does our salvation raise us to an exalted blessedness.

  This is the first chapter of this Epistle, wherein you perceive in what a masterly manner St. Peter preaches and treats of faith, whence we easily see that this Epistle is true Gospel. Now comes the second chapter, that will instruct us in matter of works, how we should conduct ourselves toward our neighbor.

  CHAPTER II.

  V. 1-5. WHEREFORE lay aside all malice, and all guile, and hypocrisies, and hatred, and all evil speakings, and desire the sincere milk of the word, as new-born babes, that ye may grow thereby, if ye have besides tasted that the Lord is gracious, to whom ye are come as to a living stone, which indeed is rejected by men, but before God is elect and precious. And be ye also as living stones built up into a spiritual house, and a holy priesthood, to offer up spiritual sacrifices acceptable to God by Jesus Christ.

  Here he begins to show what the characteristic and fruit of a christian life should be. For we have said often enough that a christian life consists in two things, — faith toward God and love toward our neighbor. Besides, although christian faith has been given us, yet as long as we live many evil lusts remain in the flesh, since every saint must be in the flesh, but what is in the flesh cannot be entirely pure. Therefore St. Peter says, be ye armed, that ye may guard yourselves against the sins which still cleave to you, and strive continually against them. For the worst enemies that we have hide themselves in our bosoms, and in our very flesh and blood, wake, sleep, and live with us, like a wicked spirit which we have brought home with us and cannot send off. Wherefore, since through faith Jesus Christ is entirely yours, and ye have obtained salvation and all His blessings, let it be your aim henceforth to lay aside all wickedness, or all that is evil, and all guile, so that no one act toward another deceitfully or falsely; as with the world it has become a common expression to say, the world is full of falsehood, which is indeed so. But we Christians should not act with such deceit, but uprightly and with pure hearts, toward men as toward God, fairly and justly, so that none take the advantage of another in sale, purchase or promise, and the like.

  Likewise also St. Paul says to the Ephesians, ch. iv., “Lay aside lying, and speak truth every one with his neighbor.” Truth is, that yea be yea, and nay, nay, — but hypocrisy, when any one represents himself by his outward mien as being what he is not in his thoughts. For solemn is the obligation that we should show ourselves to be what we are at heart. A Christian should so act that he could permit all men to see and know what he thinks in his heart. Let him, then, in all his walk and conduct, be anxious only to praise God, and serve his neighbor, and be afraid of no one; and let every one be in heart what he is in appearance, and not act a feigned part, whereby he shall make others gape with wonder.

  Furthermore, St. Peter says that we should lay aside hatred and evil speaking. Here he fitly takes up the common vices among men, in their intercourse with one another. This evil speaking is exceedingly common and injurious, — is soon done, insomuch that none of us is aware of it. Therefore he says, be on your guard, if ye already have a christian spirit, that ye may know what are the fruits of this spirit.

  V. 2. And desire the sincere milk of the word, as new-born babes. Here he institutes a comparison, and would say, — ye are like those new-born babes who seek nothing but the milk: like them, striving for the breasts and milk, so be ye also eager for the word; endeavor for it, have an appetite for it, that ye may suck in the intelligible, sincere milk.

  These words are, indeed, figurative; for he did not mean literal milk, or literal sucking, as he does not speak of a literal birth. But he speaks of another milk which belongs to the mind, which is spiritual, which is procured by the soul, which the heart must draw in. It must be, moreover, sincere (or unfalsified), not as the custom is, to sell false wares; since there is truly strong obligation, and great necessity, that to the new-born and young Christian, the milk should be given pure, and not corrupted. But this milk is nothing but the Gospel, which is a
lso the same with seed, whereby we are conceived and born, as we have heard above. Yet it is also the food which nourishes us when we arrive at maturity; it is also the harness wherewith we equip and clothe ourselves, — yea, it is all these in common. But whatever is appended to it is human doctrine, whereby the word of God is falsified; therefore the Holy Spirit would have it so that every Christian shall see to it, what he sucks for milk, and shall himself learn to decide in regard to all doctrines.

  But the breasts which yield this milk, and which the babes suck, are the preachers in the christian Church. As the bridegroom says to the bride, in Cant. iii., “Thou hast two breasts like two young roes; they are as though they were hung with a bundle of myrrh;” as the bride says, Cant. i., “My beloved is like a bundle of myrrh that lies continually between my breasts.” That is, we should ever preach Christ. The bridegroom must resort to the breasts; so that it is unjust, and the milk will be corrupt, if we do not preach Christ alone.

  There is this, besides: when it is preached that Christ died for us, and rescued us from sin, death, and hell, — this is delightful and sweet, like milk; but after this, the cross also must be preached, that we are to suffer, as we have done; and this is a strong draught, it is strong wine. Therefore, Christians should have at first given them the weakest drink, — that is, milk. For it cannot be preached in its simplicity, except Christ be preached first of all; which is not bitter, but is mere sweet, rich grace, from which you receive yet no smart. This is the sincere milk of the word.
