Romans 12:1

But as philosophers, before they lay down laws respecting morals, discourse first of the end of what is good, and inquire into the sources of virtues, from which afterwards they draw and derive all duties; so Paul lays down here the principle from which all the duties of holiness flow, even this, — that we are redeemed by the Lord for this end — that we may consecrate to him ourselves and all our members. But it may be useful to examine every part.

1. I therefore beseech you by the mercies (miserationes — compassions) of God, etc. We know that unholy men, in order to gratify the flesh, anxiously lay hold on whatever is set forth in Scripture respecting the infinite goodness of God; and hypocrites also, as far as they can, maliciously darken the knowledge of it, as though the grace of God extinguished the desire for a godly life, and opened to audacity the door of sin. But this exhortation teaches us, that until men really apprehend how much they owe to the mercy of God, they will never with a right feeling worship him, nor be effectually stimulated to fear and obey him. It is enough for the Papists, if they can extort by terror some sort of forced obedience, I know not what. But Paul, that he might bind us to God, not by servile fear, but by the voluntary and cheerful love of righteousness, allures us by the sweetness of that favor, by which our salvation is effected; and at the same time he reproaches us with ingratitude, except we, after having found a Father so kind and bountiful, do strive in our turn to dedicate ourselves wholly to him.

And what Paul says, in thus exhorting us, ought to have more power over us, inasmuch as he excels all others in setting forth the grace of God. Iron indeed must be the heart which is not kindled by the doctrine which has been laid down into love towards God, whose kindness towards itself it finds to have been so abounding. Where then are they who think that all exhortations to a holy life are nullified, if the salvation of men depends on the grace of God alone, since by no precepts, by no sanctions, is a pious mind so framed to render obedience to God, as by a serious meditation on the Divine goodness towards it?

We may also observe here the benevolence of the Apostle’s spirit, — that he preferred to deal with the faithful by admonitions and friendly exhortations rather than by strict commands; for he knew that he could prevail more with the teachable in this way than in any other.

That ye present your bodies, etc. It is then the beginning of a right course in good works, when we understand that we are consecrated to the Lord; for it hence follows, that we must cease to live to ourselves, in order that we may devote all the actions of our life to his service.

There are then two things to be considered here, — the first, that we are the Lord’s, — and secondly, that we ought on this account to be holy, for it is an indignity to God’s holiness, that anything, not first consecrated, should be offered to him. These two things being admitted, it then follows that holiness is to be practiced through life, and that we are guilty of a kind of sacrilege when we relapse into uncleanness, as it is nothing else than to profane what is consecrated.

But there is throughout a great suitableness in the expressions. He says first, that our body ought to be offered a sacrifice to God; by which he implies that we are not our own, but have entirely passed over so as to become the property of God; which cannot be, except we renounce ourselves and thus deny ourselves. Then, secondly, by adding two adjectives, he shows what sort of sacrifice this ought to be. By calling it living, he intimates, that we are sacrificed to the Lord for this end, — that our former life being destroyed in us, we may be raised up to a new life. By the term holy, he points out that which necessarily belongs to a sacrifice, already noticed; for a victim is then only approved, when it had been previously made holy. By the third word, acceptable, he reminds us, that our life is framed aright, when this sacrifice is so made as to be pleasing to God: he brings to us at the same time no common consolation; for he teaches us, that our work is pleasing and acceptable to God when we devote ourselves to purity and holiness.

By bodies he means not only our bones and skin, but the whole mass of which we are composed; and he adopted this word, that he might more fully designate all that we are: for the members of the body are the instruments by which we execute our purposes. He indeed requires from us holiness, not only as to the body, but also as to the soul and spirit, as in 1 Thessalonians 5:23. In bidding us to present our bodies, he alludes to the Mosaic sacrifices, which were presented at the altar, as it were in the presence of God. But he shows, at the same time, in a striking manner, how prompt we ought to be to receive the commands of God, that we may without delay obey them.

Hence we learn, that all mortals, whose object is not to worship God, do nothing but miserably wander and go astray. We now also find what sacrifices Paul recommends to the Christian Church: for being reconciled to God through the one only true sacrifice of Christ, we are all through his grace made priests, in order that we may dedicate ourselves and all we have to the glory of God. No sacrifice of expiation is wanted; and no one can be set up, without casting a manifest reproach on the cross of Christ.

Your reasonable service This sentence, I think, was added, that he might more clearly apply and confirm the preceding exhortation, as though he had said, — “Offer yourselves a, sacrifice to God, if ye have it in your heart to serve God: for this is the right way of serving God; from which, if any depart, they are but false worshippers.” If then only God is rightly worshipped, when we observe all things according to what he has prescribed, away then with all those devised modes of worship, which he justly abominates, since he values obedience more than sacrifice. Men are indeed pleased with their own inventions, which have an empty show of wisdom, as Paul says in another place; but we learn here what the celestial Judge declares in opposition to this by the mouth of Paul; for by calling that a reasonable service which he commands, he repudiates as foolish, insipid, and presumptuous, whatever we attempt beyond the rule of his word.
