“I beseech you therefore, brethren, by the mercies of God, that you present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service.”

After discoursing at large upon the love of God toward man, and pointing out His unspeakable concern for us, and unutterable goodness, which cannot even be searched into, he next puts it forward with a view of persuading those who have received the benefit to exhibit a conversation worthy of the gift. And though he is so great and good a person , yet he does not decline beseeching them, and that not for any enjoyment he was likely to get himself, but for that they would have to gain. And why wonder that he does not decline beseeching, where he is even putting God’s mercies before them? For since, he means, it is from this you have those numberless blessings, from the mercies of God, reverence them, be moved to compassion by them. For they themselves take the attitude of suppliants, that you would show no conduct unworthy of them. I entreat you then, he means, by the very things through which you were saved. As if any one who wished to make a person, who had had great kindnesses done him, show regard, was to bring him the benefactor himself as a suppliant. And what do you beseech? let me hear. “That ye would present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service.” For when he had said sacrifice, to prevent any from thinking he bade them kill themselves, he forthwith added “living.” Then to distinguish it from the Jewish, he calls it “holy, acceptable to God, your reasonable service.” For theirs was a material one, and not very acceptable either. Since He says, “Who has required this at your hands?” And in sundry other passages He clearly throws them aside. For it was not this, but this with the other, that He looked to have presented. Wherefore he says, “The sacrifice of praise shall glorify Me.” And again, “I will praise the name of my God with a song, and this shall please him better than a bullock that puts forth horns and hoofs.” And so in another place He rejects it, and says, “Shall I eat the flesh of bulls, or drink goat’s blood?” and proceeds with, “Offer unto God a sacrifice of praise, and pay your vows unto the Most High.” So Paul also here bids us “present our bodies a living sacrifice.” And how is the body, it may be said, to become a sacrifice? Let the eye look upon no evil thing, and it has become a sacrifice; let your tongue speak nothing filthy, and it has become an offering; let your hand do no lawless deed, and it has become a whole burnt offering. Or rather this is not enough, but we must have good works also: let the hand do alms, the mouth bless them that cross one, and the hearing find leisure evermore for lections of Scripture. For sacrifice allows of no unclean thing: sacrifice is a first-fruit of the other actions. Let us then from our hands, and feet, and mouth, and all other members, yield a first-fruit unto God. Such a sacrifice is well pleasing, as that of the Jews was even unclean, for, “their sacrifices,” it says, “are unto them as the bread of mourning.” Not so ours. That presented the thing sacrificed dead: this makes the thing sacrificed to be living. For when we have mortified our members, then we shall be able to live. For the law of this sacrifice is new, and so the sort of fire is a marvelous one. For it needs no wood or matter under it; but our fire lives of itself, and does not burn up the victim, but rather quickens it. This was the sacrifice that God sought of old. Wherefore the Prophet says, “The sacrifice of God is a broken spirit.” And the three Children offer this when they say, “At this time there is neither prince, or prophet, or leader, or burnt offering, or place to sacrifice before You, and to find mercy. Nevertheless, in a contrite heart and an humble spirit let us be accepted.” And observe how great the exactness wherewith he uses each word. For he does not say, offer your bodies as a sacrifice, but “present” them, as if he had said, never more have any interest in them. You have given them up to another. For even they that furnish the war-horses have no further interest in them. And thou too hast presented your members for the war against the devil and for that dread battle-array. Do not let them down to selfish appliances. And he shows another thing also from this, that one must make them approved, if one means to present them. For it is not to any mortal being that we present them, but to God, the King of the universe; not to war only, but to have seated thereon the King Himself. For He does not refuse even to be seated upon our members, but even greatly desires it. And what no king who is but our fellow-servant would choose to do, that the Lord of Angels chooses. Since then it is both to be presented (i.e. as for a King’s use) and is a sacrifice, rid it of every spot, since if it have a spot, it will no longer be a sacrifice. For neither can the eye that looks lecherously be sacrificed, nor the hand be presented that is grasping and rapacious, nor the feet that go lame and go to play-houses, nor the belly that is the slave of self-indulgence, and kindles lusts after pleasures, nor the heart that has rage in it, and harlots’ love, nor the tongue that utters filthy things. Hence we must spy out the spots on our body upon every side. For if they that offered the sacrifices of old were bid to look on every side, and were not permitted to offer an animal “that has anything superfluous or lacking, or is scurvy, or scabbed“, much more must we, who offer not senseless animals, but ourselves, exhibit more strictness, and be pure in all respects, that we also may be able to say as did Paul, “I am now ready to be offered, and the time of my departure is at hand.” For he was purer than any sacrifice, and so he speaks of himself as “ready to be offered.” But this will be brought about if we kill the old man, if we mortify our members that are upon the earth, if we crucify the world unto ourselves. In this way we shall not need the knife any more, nor altar, nor fire, or rather we shall want all these, but not made with the hands, but all of them will come to us from above, fire from above, and knife also, and our altar will the breadth of Heaven be. For if when Elijah offered the visible sacrifice, a flame, that came down from above consumed the whole water, wood, and stones, much more will this be done upon you. And if you have anything in you relaxed and secular, and yet offerest the sacrifice with a good intention, the fire of the Spirit will come down, and both wear away that worldliness, and perfect the whole sacrifice. But what is “reasonable service?” It means spiritual ministry, conversation according to Christ. As then he that ministers in the house of God, and officiates, of whatever sort he may be, then collects himself, and becomes more dignified; so we ought to be minded all our whole life as serving and ministering. And this will be so, if every day you bring Him sacrifices, and become the priest of your own body, and of the virtue of your soul; as, for example, when you offer soberness, when alms-giving, when goodness and forbearance. For in doing this you offer “a reasonable service“, that is, one without anything that is bodily, gross, visible. Having then raised the hearer by the names bestowed, and having shown that each man is a priest of his own flesh by his conversation, he mentions also the way whereby we may compass all this. What then is the way? — On Romans 12:1.
