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
