Psalms 50:18

But what shall we say concerning David, to whom such testimony was borne, and of whom God said, “I have found a man after Mine own heart, David the son of Jesse; and in everlasting mercy have I anointed him?” Yet this very man saith to God, “Have mercy on me, O Lord, according to Thy great mercy; and according to the multitude of Thy compassions, blot out my transgression. Wash me still more from mine iniquity, and cleanse me from my sin. For I acknowledge my iniquity, and my sin is ever before me. Against Thee only have I sinned, and done that which was evil in Thy sight; that Thou mayest be justified in Thy sayings, and mayest overcome when Thou art judged. For, behold, I was conceived in transgressions, and in my sins did my mother conceive me. For, behold, Thou hast loved truth; the secret and hidden things of wisdom hast Thou shown me. …

And who is so foolish as to suppose that the things offered to God are needed by Him for some uses of His own? Divine Scripture in many places explodes this idea. Not to be wearisome, suffice it to quote this brief saying from a psalm: “I have said to the Lord, Thou art my God: for Thou needest not my goodness.” We must believe, then, that God has no need, not only of cattle, or any other earthly and material thing, but even of man’s righteousness, and that whatever right worship is paid to God profits not Him, but man. For no man would say he did a benefit to a fountain by drinking, or to the light by seeing. …

15. What He requireth of man, let us see; what tribute our God, our Emperor and our King doth enjoin us; since He hath willed to be our King, and hath willed us to be His province? Let us hear His injunctions. Let not a poor man tremble beneath the injunction of God: what God enjoineth to be given to Himself, He doth Himself first give that enjoineth: be ye only devoted. God doth not exact what He hath not given, and to all men hath given what He doth exact. For what doth He exact? Let us hear now: “I will not reprove thee because of thy sacrifices” ( ver. 8 ). I will not say to thee, Wherefore hast thou not slain for me a fat bull? why hast thou not selected the best he-goat from thy flock? Wherefore doth that ram amble among thy sheep, and is not laid upon mine altar? I will not say, Examine thy fields and thy pen and thy walls, seeking what thou mayest give Me. …

21. “Because if Thou hadst willed sacrifice, I would have given it surely” ( ver. 16 ). David was living at that time when sacrifices of victim animals were offered to God, and he saw these times that were to be. Do we not perceive ourselves in these words? Those sacrifices were figurative, foretelling the One Saving Sacrifice. Not even we have been left without a Sacrifice to offer to God. For hear what he saith, having a concern for his sin, and wishing the evil thing which he hath done to be forgiven him: “If Thou hadst willed,” he saith, “sacrifice, I would have given it surely. With holocausts Thou wilt not be delighted.” Nothing shall we therefore offer? So shall we come to God? And whence shall we propitiate Him? Offer; certainly in thyself thou hast what thou mayest offer. …

Here then he instructs the one party to be thus minded. But when he too, who enjoys such honor from thee, is thus affected toward thee, consider what a double wall there is erected of gentle forbearance [comp. Philip. iv. 5 .]; for when thou esteemest him thus worthy of honor, and he thee likewise, no painful thing can possibly arise; for if this conduct when shown by one is sufficient to destroy all strife, who shall break down the safeguard, when it is shown by both? Not even the Devil himself. The defense is threefold, and fourfold, yea manifold, for humanity is the cause of all good; and that you may learn this, listen to the prophet, saying, “Hadst thou desired sacrifice, I would have given it: Thou wilt not delight in burnt offerings. The sacrifice for God is a broken spirit, a broken and a contrite heart God will not despise.” ( Ps. li. …

Here he does not blame those who offer, showing that it is not because of their wickednesses that He does not accept them, as He says elsewhere, but because the thing itself has been convicted for the future and shown to have no strength, nor any suitableness to the times. What then has this to do with the “sacrifices” being offered “oftentimes”? Not only from their being “oftentimes” [offered] (he means) is it manifest that they are weak, and that they effected nothing; but also from God’s not accepting them, as being unprofitable and useless. And in another place it is said, “If Thou hadst desired sacrifice I would have given it.” ( Ps. li. 16 .) Therefore by this also he makes it plain that He does not desire it. Therefore sacrifices are not God’s will, but the abolition of sacrifices. Wherefore they sacrifice contrary to His will.
