1. In the preceding sermons I have treated sufficiently of faith and love; and of crosses and afflictions, the promoters of hope. Faith, love and affliction bound the Christian's life. It is unnecessary that I should further discourse on these topics. As they—or anything pertaining to the life of the Christian—present themselves, reference may be had to those former postils. It is my purpose now briefly to make plain that the sum of all divine doctrine is simply Jesus Christ, as we have often heard.
2. This epistle lesson treats not of faith, but of the fruits of faith—love, unity, patience, self-denial, etc. Among these fruits, the apostle considers first the discipline of the body—the mortification of evil lusts. He handles the subject here in a manner wholly unlike his method in other epistles. In Galatians he speaks of crucifying the flesh with its lusts; in Hebrews and Colossians, of putting off the old man and mortifying the members on earth. Here he mentions presenting the body as a sacrifice; he dignifies it by the loftiest and most sacred terms. Why does he so?
First, by making the terms glorious, he would the more emphatically urge us to yield this fruit of faith. The whole world regards the priest's office—his service and his dignity—as representing the acme of nobility and exaltation; and so it truly does. Now, if one would be a priest and exalted before God, let him set about this work of offering up his body to God; in other words, let him be humble, let him be nothing in the eyes of the world.
3. I will let every man decide for himself the difference between the outward priesthood of dazzling character and the internal, spiritual priesthood. The first is confined to a very few individuals; the second, Christians commonly share. One was ordained of men, independently of the Word of God; the other was established through the Word, irrespective of human devices. In that, the skin is besmeared with material oil; in this, the heart is internally anointed with the Holy Spirit. That applauds and extols its works; this proclaims and magnifies the grace of God, and his glory. That does not offer up the body with its lusts, but rather fosters the evil desires of the flesh; this sacrifices the body and mortifies its lusts. The former permits the offering up to itself of gold and property, of honor, of idleness and pleasure, and of all manner of lust on earth; the latter foregoes these things and accepts only the reverse of homage. That again sacrifices Christ in its awful perversions; this, satisfied with the atonement once made by Christ, offers up itself with him and in him, by making similar sacrifices. In fact, the two priesthoods accord about as well as Christ and Barabbas, as light and darkness, as God and the world. As little as smearing and shaving were factors in Christ's priesthood, so little will they thus procure for anyone the Christian priesthood. Yet Christ, with all his Christians, is priest. "Thou art a priest for ever after the order of Melchizedek." Ps 110, 4. The Christian priesthood will not admit of appointment. The priest is not made. He must be born a priest; must inherit his office. I refer to the new birth—the birth of water and the Spirit. Thus all Christians become priests, children of God and co-heirs with Christ the Most High Priest.
4. Men universally consider the title of priest glorious and honorable; it is acceptable to everyone. But the duties and the sacrifice of the office are rarely accepted. Men seem to be averse to these latter. The Christian priesthood costs life, property, honor, friends and all worldly things. It cost Christ the same on the holy cross. No man readily chooses death instead of life, and accepts pain instead of pleasure, loss instead of gain, shame rather than honor, enemies rather than friends, according to the example Christ set for us on the cross. And further, all this is to be endured, not for profit to one's self, but for the benefit of his neighbor and for the honor and glory of God. For so Christ offered up his body. This priesthood is a glorious one.
5. As I have frequently stated, the suffering and work of Christ is to be viewed in two lights: First, as grace bestowed on us, as a blessing conferred, requiring the exercise of faith on our part and our acceptance of the salvation offered. Second, we are to regard it an example for us to follow; we are to offer up ourselves for our neighbors' benefit and for the honor of God. This offering is the exercise of our love—distributing our works for the benefit of our neighbors. He who so does is a Christian. He becomes one with Christ, and the offering of his body is identical with the offering of Christ's body. This is what Peter calls offering sacrifices acceptable to God by Christ. He describes priesthood and offering in these words: "Ye also, as living stones, are built up a spiritual house, to be a holy priesthood, to offer up spiritual sacrifices, acceptable to God through Jesus Christ." 1 Pet 2, 5.
6. Peter says "spiritual sacrifices," but Paul says our bodies are to be offered up. While it is true that the body is not spirit, the offering of it is called a spiritual sacrifice because it is freely sacrificed through the Spirit, the Christian being uninfluenced by the constraints of the Law or the fear of hell. Such motives, however, sway the ecclesiasts, who have heaped tortures upon themselves by undergoing fasts, uncomfortable clothing, vigils, hard beds and other vain and difficult performances, and yet failed to attain to this spiritual sacrifice. Rather, they have wandered the farther from it because of their neglect to mortify their old Adam-like nature. They have but increased in presumption and wickedness, thinking by their works and merits to raise themselves in God's estimation. Their penances were not intended for the mortification of their bodies, but as works meriting for them superior seats in heaven. Properly, then, their efforts may be regarded a carnal sacrifice of their bodies, unacceptable to God and most acceptable to the devil.
7. But spiritual sacrifices, Peter tells us, are acceptable to God; and Paul teaches the same (Rom 8, 13): "If by the Spirit ye put to death the deeds of the body, ye shall live." Paul speaks of mortifying through the Spirit; Peter, of a spiritual sacrifice. The offering must first be slain. Paul's thought is: "If ye mortify the deeds of the body in your individual, chosen ways, unprompted by the Spirit or your own heart, simply through fear of punishment, that mortification—that sacrifice—will be carnal; and ye shall not live, but die a death the more awful." The Spirit must mortify your deeds—spiritually it must be done; that is, with real enjoyment, unmoved by fear of hell, voluntarily, without expectation of meriting honor or reward, either temporal or eternal. This, mark you, is a spiritual sacrifice. However outward, gross, physical and visible a deed may be, it is altogether spiritual when wrought by the Spirit. Even eating and drinking are spiritual works if done through the Spirit. On the other hand, whatsoever is wrought through the flesh is carnal, no matter to what extent it may be a secret desire of the soul. Paul (Gal 5, 20) terms idolatry and heresies works of the flesh, notwithstanding they are invisible impulses of the soul.
8. In addition to this spiritual sacrifice—the mortifying of the deeds of the body—Peter mentions another, later on in the same chapter: "But ye are ... a royal priesthood ... that ye may show forth the excellencies of him who called you out of darkness into his marvelous light." Here Peter touches upon the preaching office, the real sacrificial office, concerning which it is said (Ps 50, 23), "Whoso offereth the sacrifice of thanksgiving glorifieth me." Preaching extols the grace of God. It is the offering of praise and thanks. Paul boasts (Rom 15, 16) that he sanctifies and offers the Gospel. But it is not our purpose to consider here this sacrifice of praise; though praise in the congregation may be included in the spiritual sacrifice, as we shall see. For he who offers his body to God also offers his tongue and his lips as instruments to confess, preach and extol the grace of God. On this topic, however, we shall speak elsewhere. Let us now consider the words of the text.
