Augustine of Hippo : God seeks us, not what's ours. Anyway, the Christian's sacrifice is alms, or kindness to the poor. That is what makes God lenient toward sins. — SERMON 42:1 Jerome : (Verse 12.) For who indeed sought these things from your hands? Let the Ebionites hear, who after the passion of Christ think that the Law has been abolished and should be observed. Let the associates of the Ebionites hear, who decree that these things should be observed only by Jews and those of Israelite descent. Therefore, the offering and sacrifice of victims were not primarily sought by God, but so that they would not be made to idols; and so that we might pass from carnal victims, as it were by a type and image, to spiritual sacrifices. But by saying that he did not desire sacrifices, he showed that the law is spiritual: and that all the things that the Jews do in a carnal way are fulfilled spiritually by us. — Commentary on Isaiah John Chrysostom : It is obvious that sacrifices were established as an instruction to inspire right living in the people and were not given as an end in themselves. When the people refused to do those works that were necessary in order to busy themselves with only sacrifices, God said that he would no longer accept the sacrifices.The entire book of Leviticus offers laws that are very strict regarding sacrifices. Moreover, there are numerous laws concerning sacrifices scattered throughout the book of Deuteronomy, as well as other books. How then can God ask, "Who has required these things from your hands?" This is to teach us that God's will was not to make laws in this way but that the people suffered from slothfulness in not abiding by this command. — COMMENTARY ON Isaiah 1:4 Tertullian : As for the burdensome sacrifices and the troublesome scrupulousness of their ceremonies and oblations, no one should blame the Jews, as if God specially required them for himself.… But he should see in those sacrifices a careful provision on God's part, which showed his wish to bind to his own religion a people who were prone to idolatry and transgression by that kind of services wherein consisted the superstition of that period. He did this in order to call them away from idolatry, while requesting sacrifices to be performed to himself, as if he desired that no sin should be committed in making idols. — AGAINST MARCION 1. Tertullian : Now this is the spiritual victim which has set aside the earlier sacrifice.… The gospel teaches what God demands. "The hour is coming," he says, "when the true worshipers will worship the Father in spirit and in truth." … We are the true worshipers and true priests who, offering our prayer in the spirit, offer sacrifice in the spirit—that is, prayer—as a victim that is appropriate and acceptable to God; this is what he has demanded and what he has foreordained for himself. — ON PRAYER 28
