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.
