The Epistles of St. Peter and St. Jude Preached and Explained

Gird up the loins of your mind. Here Peter speaks of a spiritual girding of the mind, just as one girds his sword to the loins of his body. This girding has Christ also enforced, Luke xii., where he says, "Let your loins be girt about." In some places the Scriptures speak of the loins with reference to bodily lust; but here St. Peter speaks of the loins of the spirit. As to the body, Scripture speaks of the loins with reference to natural generation from the father; as we read, Genesis xlix., that from the loins of Judah Christ should come. Likewise the bodily girding of the loins is the same with chastity, as Isaiah says, chapter xi., "Righteousness shall be the girdle of his loins, and faith the girdle of his reins." That is, only by faith is wicked lust subdued and restrained.

But this spiritual girding, whereof the Apostle speaks, means more. As a virgin is pure and inviolate in body, so is the soul spiritually inviolate through faith, by which it becomes Christ's bride. But if it falls from faith into false doctrine, it must be brought to shame. Hence Scripture uniformly calls impiety and unbelief, adultery and whoredom,—that is, when the soul relies on human doctrines, and thus lets go its hold on faith and Christ. This St. Peter here forbids, when he calls on us to gird up the loins of our mind; as though he would say, ye have now heard the Gospel and have come to believe, therefore see to it that ye abide therein, and do not suffer yourselves to be drawn away with false doctrine, so that ye shall not waver and run hither and thither with works.

And here he adopts a peculiar mode of speech, not after the manner of St. Paul, where he speaks of "the loins of your mind." He calls that mind here which we speak of as disposition; as when I say, "This seems to me right and as Paul speaks, so we understand it, so we are disposed." In this he refers especially to faith, and would say: ye have attained a correct apprehension that we must be justified through faith; abide in that mind; gird it up well, hold fast thereon, and suffer not yourselves to be torn from it; then shall ye stand well. For many false teachers shall come in and set up human doctrines that they may pervert your understanding and loose the girdle of your faith; wherefore be admonished, and bind it well to your mind.

The hypocrites who rest on their own works, and hence pass a carefully abstemious life, are thus minded, that God must bring them to heaven for their works' sake; they are puffed up, become proud, abiding in their own opinion and blindness, like the Pharisees, Luke xviii. Of whom also Mary speaks, in the Magnificat, where she uses the same word that stands here in Peter, He hath scattered the proud in the disposition of their hearts,—that is, in their own minds.

Be sober. To be sober is of service outwardly to the body, and is the chief work of faith. For though a man has been justified, he still is not secured from evil lusts; faith has indeed begun to subdue the flesh, but this is ever bestirring itself, and likewise running riot in all sorts of lusts, which would gladly break forth again and act after their own will. Therefore the spirit must daily work to restrain and subdue it, and must charge itself therewith, without intermission, and have a care of the flesh that it do not destroy faith. Therefore those persons deceive themselves, who indeed say they have faith, and imagining that this is enough, live thenceforth according to their own caprice. Where the faith is genuine it must control the body and hold it in check, so that it shall not do what it lusts after. Therefore St. Peter says that we should be sober.

Yet he would not have us destroy the body or weaken it too much, as we find many do who have fasted and tortured themselves to death. St. Bernard, even, continued for a long time in this folly, although he was truly a holy man, for he mortified his body to such an extent that his breath was offensive and could not be endured. Yet he afterwards forsook it, and charged his brethren that they should not inflict injury upon the body; for he saw very well that he had rendered himself unfit to be of service to his brethren. Therefore St. Peter requires nothing more than that we should be sober,—that is, mortify the body to such an extent as to prevent its being in our apprehension too wanton; for he fixes no definite time how long we should fast, as the Pope has done, but leaves it to each, individually, to fast so that he remain sober and do not burden the body with gluttony, to the end that he remain in possession of reason and reflection, and consider how far it is necessary for him to hold the body in check. For it is utterly idle to impose one and the same command upon a whole congregation and church, since we are so unlike one to the other; one strong, another weak in body,—so that one must mortify it more, another less, provided the body is to remain sound and in the best state for exertion.

But another multitude mistake here, determined that they will not fast, and that they may eat flesh, and herein are wrong. For these persons reject the Gospel also, and are unprofitable as well as the others; doing no more than contemn the Pope's command, unwilling to gird up their mind and spirit, as Peter says, leaving the body to its own caprice, that it may become corrupt and wanton. It is well to fast; but that only can be called true fasting, when we give the body no more food than is needful for it that it may retain its health and endure labor and watchfulness—that the old ass do not become too obstinate, and going on the ice to dance, break a bone; but go on subject to control, and following the spirit; not after the manner of those who, whenever they fast, fill themselves so full of fish and the best wine, that their bellies are puffed out. Thus St. Peter directs us to be sober, and now says further:

And fix your hope firmly (or with all deliberation) on the grace which is offered you. The christian faith is of such a nature that it plants itself freely on the word of God with entire confidence, ventures freely thereupon, and goes joyfully onward. Therefore Peter would say: The loins of your mind are girt about, and your faith is genuine, when you venture it thus on that Word, let it cost what it will,—property, honor, limb, or life.

Thus has he with these words in truth well described a genuine and unfeigned faith. It must not be a corrupt and sleepy faith, becoming thus only a dream, but a living and active reality, that we may with all deliberation devote ourselves to it and cleave to the Word, so that, let God permit it to go with us as it will, we will yet press onward through good and ill. Thus when I come to die I must venture promptly on Christ, lift my head boldly, and rely upon the word of God which cannot deceive me. Thus must faith go straight forward, in nothing permit itself to be led astray, and subject to scrutiny all that it sees, hears and feels. Such faith St. Peter requires as consists, not in thought or word, but in such power as this.

Again, St. Peter says: Set your hope on the grace which is offered you. That is, ye have not deserved this great grace, but yet it is freely offered you; for the Gospel, which reveals this grace, is no invention or discovery of our own, but the Holy Spirit has sent it down from heaven into the world. But what is it that is offered to us? This, that we have already heard, that whosoever believes on Christ and cleaves to the Word possesses Him, with all the blessings He has to give, so that He is Lord over sin, death, the devil and hell, and is assured of eternal life. This treasure is brought to our doors and laid in our bosom without our help or desert, yes, beyond our expectation and without our knowledge or thought. Therefore the Apostle would have us venture thereon cheerfully, for God, who offers us such grace, will surely not deceive us.

Through the revelation of Jesus Christ. God permits none to make the offer of His grace except through Christ. Therefore no man should attempt to approach Him apart from this Mediator, as we have already above heard sufficiently. For He will hear no one but him who brings His dear Son with him, whom He alone regards, and for His sake those that depend upon Him. Therefore He would have us confess the Son, that we are reconciled through His blood to the Father, so that we may approach before Him. For to this end did Christ come into the world, assume flesh and blood, and joined Himself to us, that He might obtain such grace for us with the Father. So, too, all the prophets and patriarchs have been kept and saved, through such faith on Christ. For they all have exercised faith in the promise which God made to Abraham, "Through thy seed shall all nations be blest." Therefore, as we have said, to the Jews and to the Turks, faith is of no avail, neither to any that rest upon their own works and would thereby reach heaven. So Peter says, this grace is offered you, but it is through the revelation of Jesus Christ (or to render it more clearly into our language), because that Jesus Christ has been revealed to you.

Through the Gospel it is made known to us what Christ is, that we may learn of Him, moreover, that He is our Saviour. He rescues us from sin and death, and helps us out of every evil, reconciles us to the Father, and, apart from our own works, justifies and saves us. Whoever then does not thus confess Christ must be lost; for although you may know that He is the Son of God, that He died and has risen, and sits at the right hand of the Father,—still you have not yet truly known Christ, it is all of no avail to you; but you must know and believe that He has done it all for your sake, if your faith is to help you. Therefore that is a vain, senseless doctrine that has been hitherto preached and taught in the great schools, which have had no experience of this knowledge, and have only attained to imagine how the curse afflicted Christ our Lord, and how He sits above in heaven unemployed, and possesses a joy with Himself; and thus their hearts remain barren, so that faith cannot live in them. But Christ does not stand there for Himself, but He is to be preached that He is ours. For what necessity could there then have been that He should have come down to earth and have shed His blood? But since He has been sent into the world, as He says, John iii., "that the world through Him might be saved." He certainly must have fulfilled this mission, because He was sent from the Father. For this sending forth and proceeding from the Father is to be understood not only of the divine nature, but also of the human nature and of His ministry. As soon as He was baptized this began, and He has fulfilled it, for which end He was sent and came into the world, to wit, that He might preach the truth and obtain it for us, that all who believe on Him shall be saved. Thus has He revealed Himself, and presented Himself to our knowledge, and offered us grace.

V. 14. As obedient children. That is, conduct yourselves as obedient children. Obedience in Scripture means faith. But the Pope, with his high schools and cloisters, has even wrested the word from us, and falsely rendered what is recorded in Scripture concerning this obedience, as the passage in I. Kings xv.: "Obedience is better than sacrifice." For while they perceive that obedience is highly praised in Scripture, they have usurped the claim of it to themselves, so that they might blind the people, and that men should think it was obedience to their stuff of which the Scripture speaks. Thus they would bring us away from God's word to their lies, and to the obedience of the devil. Whoever hears the word of God and believes thereon, is an obedient child of God. Therefore, whatever is not the word of God, tread it under your feet and pay no attention to it.

Not conformed to the former lusts of your ignorance. That is, that you should not exhibit such ostentation and lead such a course of life as before, and that you be not found in the same condition in which you formerly were. Once you were godless, and lived in lewdness, gluttony, drunkenness, avarice, pride, anger, envy and hate, which was an evil, heathen-like state, and one of unbelief, and when you had gone into such a state like the blind, you have not known what you have done. Avoid now those same evil lusts. Here you perceive how he makes the charge against ignorance, that all evil proceeds therefrom. For where faith and the knowledge of Christ are wanting, there remains mere error and blindness, so that men are ignorant of what is right and wrong, insomuch that the people fall into every kind of vice.

Thus has it been hitherto: where Christ has been kept out of sight and eclipsed, there error has begun to prevail; and throughout the world the question has torn its way, how man may be saved. This is at once a sign of blindness or ignorance, that the true apprehension of faith is lost, and no one knows anything more about it. Hence the world is so full of such various sects, and all are divided, for every one will devise for himself a way to heaven of his own. In our misfortune we must be continually falling deeper in our blindness, since we cannot help ourselves. Therefore St. Peter would say: Ye have already befooled yourselves enough; now desist therefrom, since ye have been instructed and have attained to a correct understanding.

V. 15, 16. But according as He that hath called you is holy, so be ye also holy in all your conduct, as it is written, Be ye holy for I am holy. Here St. Peter quotes a passage from the Old Testament, Lev. xix., where God says: "Be ye holy for I am holy;" that is, since I am your Lord and God, and ye are my people, ye too must be as I am. For a faithful master secures that his people shall be like him, and walk in obedience, and be conformed to the master's will. As then God our Master is holy, so are His people holy also, and we are all holy if we walk in faith. Scripture says not much of the saints that have died, but of those who live on the earth. So David puts forth his claim in Ps. lxxxv.: "Lord, preserve my soul, for I am holy."

But here our learned men have for once perverted the passage, and they say: the prophet had a particular revelation, in that he called himself holy; whereby they themselves confess that they do violence to faith, and have not the revelation of Jesus Christ, otherwise they would surely be sensible of it. For whoever is a Christian experiences within himself such a revelation; but they who do not experience it are not Christians. For whoever is a Christian enters into a participation with Christ our Lord, of all his good things. Since, then, Christ is holy, he must also be holy, or deny that Christ is holy. Hast thou been baptized? then thou hast put on the holy garment, which is Christ, as Paul says.

The word Holy means that which is God's own, and which belongs to Him alone, or as we render it in Dutch (geweiht), consecrated. Thus, Peter here says: you are merely required to give God His own; therefore beware that ye do not suffer yourselves to be led back again to worldly lusts, but let God alone rule, live and work within you; then shall ye be holy, even as He is holy.

Thus he has hitherto described the grace which is extended to us through the Gospel and the preaching of Jesus Christ, and has taught us how we should therefore conduct ourselves, namely: that we abide in a pure, inviolate mind of faith, since we know that no work that we can do or imagine, can at all help us: when such doctrine as this is preached, reason objects, and says, Ah! if that is true, I need not do any good work. And then the great heads fall foul of it, and from a christian condition, educe a freedom of the flesh, imagining they may do what they will. These St. Peter here meets, and anticipates them, and teaches how we are to use our christian freedom only towards God. For nothing more is needed but faith, to the end that I should give God the honor due Him, and embrace Him as my God, confessing that He is just, true and merciful; such faith sets us free from sin and all evil. If now I have made such a return to God, whatever time I yet live I am to live for my neighbor, so as to serve and help him. The greatest work that follows from faith is this: that with my mouth I should confess Christ, sealing that confession with my blood, and laying down my life for it, if so it be. Yet God does not need this work; only I am to perform it, that my faith may thereby be tried and known, so that others also may be brought to believe. Thereafter follow also other works, which must all be directed to this end, that I may thereby serve my neighbor,—all of which God must work in us; for it profits not that we should lead a carnal life and do whatever we please. Therefore St. Peter now says:

V. 17-21. And since ye call on the Father, who judgeth without respect of persons, according to every man's work, pass the time of your sojourning here in fear; and be aware that ye are not redeemed with corruptible silver or gold, from your vain conduct in the traditions of your fathers, but with the precious blood of Christ, as of an innocent and unspotted Lamb, who indeed was provided previously before the world began, but is revealed in these last times for you, who through Him believe on God, who raised Him from the dead, and hath given Him dominion, that your faith and hope might be in God.

So says St. Peter: Ye have through faith hereunto attained, that ye are the children of God, and He is your Father. And ye have obtained an incorruptible inheritance in heaven, (as has been already said.) Thus nothing more now remains, except that the veil be taken away, and that be uncovered which is now concealed, for which ye are still to wait until ye shall behold it. Though ye are now arrived at that state in which ye may joyfully call God your Father, yet is He so righteous that he will reward every man according to his works, and respect not persons. Wherefore thou art not to imagine, although thou hast that great name so that thou art called a Christian or a child of God, that He will therefore continue thine if thou livest without fear, and thinkest that it is enough that thou dost glory in such a name. The world indeed judges by the person, since it does not punish all alike, and respects those who are friendly, rich, reputable, learned, wise, and powerful. But God regards nothing of this kind; it is all alike to him, be the person as great as he may. Thus in Egypt he struck the son of King Pharaoh dead, as well as the son of the poor miller.

Therefore the Apostle would have us expect such judgment from God, and stand in fear, so that we do not glory in our title that we are Christian, and thereupon become negligent, as though he would for this reason pass us over more readily than others. For in this the Jews were formerly deceived, who boasted that they were Abraham's seed and God's people. Scripture makes no difference in respect to the flesh, but in respect to the spirit. It is true that Christ was to be born of Abraham's seed and that a holy people should spring from him, but it does not therefore follow that all who are born of Abraham are the children of God. He also promised that the Gentiles should be saved, but he has not said that he would save all the Gentiles.

But here now a question arises: When we say that God saves us alone by faith, without regard to works, why does St. Peter say that He judges not according to the person, but according to works? Answer. What we have taught as to faith alone justifying before God, is true beyond doubt, since it is so clear from Scripture that it cannot be denied. That which the Apostle here says, that God judges according to the works, is also true; but we must certainly hold, therefore, that where there is no faith, there can be no good work; and on the other hand, that there is no faith where there are no good works. Therefore join together faith and good works, since it is in both that the sum of the whole christian life consists. As you now live, so will it be with you, for thereafter God will judge you. Therefore, although God judges us according to our works, still it remains true that works are only the fruits of faith, by which we perceive when there is faith or unbelief; therefore God will sentence you from your works and convict you, either that you have or have not believed. So it is that no one can convict and judge a liar, except from his words. Yet it is evident that he is not made a liar by the word, but became a liar before he spoke the lie, for the lie must come from the heart into the mouth. Therefore, understand this passage thus, in the plainest way: that works are fruits and signs of faith, and that God judges men according to such fruits which must certainly follow it, so that it shall be openly seen whether there is faith or unbelief in the heart. God will not judge by this whether you are called a Christian, or have been baptized, but will ask you, "Art thou a Christian? then tell me where are the fruits by which you can evidence your faith."

Therefore St. Peter goes on to say: Since ye have such a Father, who judges not after the person, pass the time of your pilgrimage in fear; that is, stand in fear before the Father, not of pain and punishment,—as the Christless, and even the devil, is afraid,—but lest He forsake you and withdraw His hand; just as a dutiful child is afraid lest he provoke his father, and do something that might not please him. Such a fear would God have within us, that we guard ourselves against sin, and serve our neighbor, while we live here upon the earth.

A Christian, if he truly believes, possesses all the good things of God, and is God's child, as we have heard. But the time which he yet lives is only a pilgrimage: for the spirit is already in heaven by faith, through which he becomes Lord over all things. But to this end God permits him yet to live in the flesh, and his body to remain on earth, that he may help others and bring them also to heaven. Therefore we are to use all things on earth as a guest, who goes on wearily and arrives at an inn where he must tarry over night, and can receive nothing from it but food and lodging; yet does not say that the property of the inn is his. So must we also proceed in regard to our temporal possessions, as though they were not ours, and we enjoyed only so much of them as is needful to sustain the body, and with the rest we are to help our neighbor. Thus the christian life is only a night's sojourning; for we have here no abiding city, but must find it, where our Father is, in heaven. Therefore we should not here live in wantonness, but stand in fear, says St. Peter.

V. 18. And be aware that ye are not redeemed with corruptible silver or gold, from your vain conduct in the traditions of your Fathers, but with the precious blood of Christ. This should draw you, he would say, to the fear of God, wherein ye should stand, that ye should remember how much it has cost that ye might be redeemed. Before, ye were citizens of the world, and were held in subjection to the devil, but now, God has rescued you from such a state, and set you firm in another, so that your citizenship is in heaven; but ye are strangers and guests upon earth. And see at how great a cost God has reclaimed you, and how great the treasure is, wherewith ye are purchased, and brought into this state, to become the children of God. Wherefore pass your sojourning in fear, and see to it that ye do not despise such redemption, and lose the noble, precious treasure.

What now is the treasure wherewith ye are ransomed? Not corruptible gold or silver, but the precious blood of Christ the Son of God: the treasure is so costly and noble, that no human sense or reason can conceive it, insomuch that only one drop of this innocent blood were more than enough for the sin of all the world: yet has the Father been willing to dispense his grace so richly upon us, and denied Himself so much as to suffer Christ His Son to shed all His blood for us, and has bestowed upon us the whole treasure. Therefore He would not have us disregard such great grace, and count it as a small matter, but continue on our guard, so as to live in fear, that this treasure be not taken away from us.

And here it is well to remark, that St. Peter says, ye are ransomed from your vain conversation in the traditions of your fathers; for he thereby strikes to the ground all the supports whereon we lean when we imagine our view must be right because it has thus been preserved from of old, and our forefathers all of them have so held it, among whom there were certainly wise and pious people. It is as much as to say, all which our fathers have ordained and done, was evil; what from them has been taught you of the worship of God, is also evil; for it has cost the Son of God His blood to redeem the people therefrom; whatever, therefore, has not been washed in this blood, is all poisoned and cursed by reason of the flesh. Thence it follows, the more a man undertakes to make himself righteous and has not Christ, the more only he confounds himself, and sinks deeper in blindness and wickedness, and condemns himself in respect to this precious blood.

External matters, important in themselves, are even trifling in comparison with this, that a man should teach how we may be justified by works, and devise a worship of God according to our reason; for thereby the innocent blood is most deeply dishonored and reviled.

The heathen have committed many great sins, in that they have prayed to the sun and moon, which they held for the true worship of God, though this was joined with other sins. But human justification (justification by human works) is mere reviling of God, and the greatest of all sins that a man commits. So, also, that mode of life wherewith the world is now busied and which it holds as the worship of God, and piety, is in God's sight more provoking than any other sin, as is the priestly and monkish order, and which while it appears fair before the world, is yet without faith. Therefore whoever will not obtain favor before God through this blood, it were better for him that he should never come into God's presence, for he thereby only the more and more dishonors His Majesty.

V. 19. As of an innocent and unspotted lamb. But here St. Peter explains the Scripture,—for this though so short is an exceedingly rich Epistle,—since as soon as he had spoken of their vain course in the traditions of the fathers, he finds much instruction for us in the prophets—as in the prophet Jer. xvi.: "The heathen shall come to you from the end of the world, and say, our fathers have gone astray with lies," as though St. Peter had said, there the prophets foretold that ye should be redeemed from the tradition of your fathers.

So when he says here, ye are redeemed by the blood of Christ, as of an innocent and unspotted lamb, he would again refer to the Scripture, and explain that which is contained in the prophets and Moses—as Is. liii.: "Like a lamb he is led to the slaughter." So as to the type, Ex. xii., of the Paschal Lamb, all this he here explains, and says, this lamb is Christ; and as the one of old was to be unspotted, so must this, also, whose blood is shed for us, be unspotted and innocent.

V. 20. Which indeed was provided previously, before the world began, but is revealed in these last times for you. That is, we have not deserved nor even prayed this of God, that the precious blood of Christ should be shed for us, therefore we can glory in no respect; the glory belongs to none but God alone. God has promised and revealed or made known to us, not for any merit of ours, that which He from all eternity had provided and foreordained, before the world was made. In the prophets it is indeed promised, yet dimly and not openly; but now, since Christ's resurrection and the sending of the Holy Spirit, it is publicly preached and disseminated throughout the whole world.

This is now the latter age (the last time), as St. Peter says, wherein we live—now—from the ascension of Christ until the last day. So the Apostles and prophets, and Christ Himself, also, call it the last hour; not that the last day was to come immediately after Christ's ascension, but because after this preaching of the Gospel of Christ no other should ever come; and there will be no further revelation or manifestation, except as this is explained and revealed. One revelation after another has indeed gone forth. Therefore God says, Ex. vi., "By my name Jehovah was I not known to them." For the patriarchs, although they knew God, yet at that time had not so clear a manifestation of Him as was afterwards put forth through Moses and the prophets; but now there has no more glorious or clear manifestation of Him come into the world than the Gospel. Therefore it is the last; all dispensations have run their course, but the present,—the last,—which is revealed to us.

Besides, the time hereafter is not long to the end of the world, as St. Peter shows, II. Pet. iii., where he says: "One day is with the Lord as a thousand years, and a thousand years as one day." And so he would lead us by this reckoning of time, to conclude, after God's method, that it is the last time, and that the end approaches, but the time which still remains is nothing in the sight of God. The salvation is already revealed and completed: God permits the world to stand yet longer, merely that His name may be more widely honored and praised, although He for Himself is now fully revealed.

V. 21. For you, who through Him believe on God, who raised Him from the dead, and hath given Him dominion that your faith and hope might be in God. For our sakes, he says, is the Gospel revealed. For God and the Lord Christ have not needed it, but have done it for our profit, that we might believe on them; and that, not through ourselves, but through Christ, who intercedes for us with the Father, whom He has raised from the dead, that He might be Lord over all things; so that whoever believes on Him possesses all His good things, and through Him has access to the Father. Thus we have faith in God, and a hope through the same faith. Faith alone must save us, but it must be a faith in God; for if God does not help us, then we are not holpen; so that it is not enough, although you had all men's friendship, but you must have the friendship of God, that you may boast that He is YOUR Father, and that you are His child, and confide in Him even more than in your beloved father and mother, that He will help you in all your troubles, and this only through the one Mediator and Saviour, the Lord Christ. Such faith comes not (he says) from human power, but God creates it in us, because Christ has merited it by His blood; to whom He has given glory, and whom He has seated at His right hand, that He, by God's power, should produce faith in us.
