Now St. Peter says further:
V. 11. Which spirit testified beforehand the sufferings of Christ, and the glory that should thereafter be revealed. This may be understood of both kinds of suffering, — that which Christ, and we also, suffer. St. Paul calls the sufferings of all Christians the suffering of Christ. For just as the faith, the name, the word and work of Christ are mine, inasmuch as I believe on Him, so His suffering is also mine, since I suffer also for His sake. Thus will the sufferings of Christ be daily fulfilled in Christians, until the end of the world.
This is then our consolation in all the sufferings that we experience, that all that we suffer Christ shares with us, that He accounts it all as His own suffering. And of this we are assured, that speedily after suffering glory shall follow. But this we must also understand, that Christ was not glorified before He suffered, so that we are to bear our cross with Him first, that afterward we may share His joy.
All that we now preach, he says, the prophets previously foretold and described in the most explicit manner, just as the Holy Spirit revealed it to them. That we so imperfectly understand the prophets is, because we do not understand their language, since they have spoken clearly enough. Therefore they that are acquainted with the language, and have the Spirit of God, which all believers have, to them it is not difficult of apprehension since they know the scope of all Scripture. But if any one does not understand their language, and has not the spirit, or a christian apprehension, it might seem to him as though the prophets were drunken and full of new wine; although where we must want one, the spirit without the language is better than the language without the spirit. The prophets have a peculiar phraseology, but the sentiment is the same which the Apostles preach, for both have spoken largely of the suffering and of the glory of Christ, as well as of those things that relate to faith. As when David speaks of Christ (Ps. xxi.), “I am a worm and no man,” whereby he shows how deeply he is cast down and despondent in his suffering. Likewise, also, he writes of his people and of the affliction of Christians, in Psalm xlv.: “We are despised, and accounted as sheep for the slaughter.”
V. 12. That not for their own sakes but for ours did they minister that which is now preached unto you, by those who have preached the Gospel to you, through the Holy Ghost sent down from heaven; that is, the prophets possessed enough thereof to know the fact. But that they should have left it behind them (on record) calls for our gratitude; they have become our servants, and have so ministered to us, that we, through them, might go to school and learn the same lesson. There we have an argument to show that our faith should grow stronger, and we be enabled to arm and sustain ourselves against all false doctrine.
Into which also the angels desired to look. So great things have the Apostles declared to us, through the Holy Spirit, which descended upon them from heaven, as even the angels would gladly look into. When this Spirit opens our eyes and makes us see what the Gospel is, we shall have an appetite for it and a joy in it, although we cannot behold it with bodily eyes, but must believe that we are partakers and fellow-heirs of the righteousness, truth, salvation and all the blessings which God has to bestow. For since He has given us His only Son, that highest good, He will also, through Him, give us all good things, riches and treasures, whereof the angels in heaven have all their joy, and of which they are most desirous. All this is offered to us through the Gospel, and if we believe we shall also have a like desire for them. But our desire for them cannot be as perfect as that of the angels, so long as we live on earth; but it is a good beginning in us, if we experience, through faith, something of it. But in heaven it is so great that no human heart can conceive it; but if we reach that place we shall ourselves feel it.
Thus you see how St. Peter teaches us to arm and equip ourselves with Scripture. For hitherto he has described what it is to preach the Gospel, and shown that as it heretofore has been preached by the prophets, so it should still be, and should be preached in like manner. Now he proceeds farther, and admonishes us in this chapter that we should cleave to the same preaching of the Gospel by faith, and follow after it by love, and therefore says, —
V. 13-16. Gird up therefore the loins of your mind; be sober, and fix your hope firmly on the grace which is offered you through the revelation of Jesus Christ, as obedient children, not conformable to the previous lusts of your ignorance; but as He who has called you is Holy, be ye also holy in all your conduct, as it is written, Be ye holy for I am Holy.
This is an admonition to faith, and the sense is this: while such things are preached to you and bestowed upon you through the Gospel as the angels would rejoice and be desirous to behold, rely on them, and fix your confidence thereon with all firmness, so that it shall be a real faith, and not a painted or fictitious fancy or dream.
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 t
he 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.
