Ambrose of Milan : For the Word of God Himself tells us that He prefers the performance of His commandments to the offering of sacrifice. God proclaims this, Moses declares it to the people, Paul preaches it to the Gentiles. Do that which you understand is most profitable for the time. "I prefer mercy," it is said, "rather than sacrifice." Are they not, then, rather Christians in truth who condemn their own sin, than they who think to defend it? "The just is an accuser of himself in the beginning of his words." He who accuses himself when he has sinned is just, not he who praises himself. — Letter 51:15 Clement of Alexandria : For to every one who has turned to God in truth and with a whole heart, the doors are open, and the thrice-glad Father receives his truly repentant child. And true repentance is to be no longer bound in the same sins for which he denounced death against himself, but to eradicate them completely from the soul. For on their uprooting God takes up his abode again in you. For it is said there is great and exceeding joy and festivity in the heavens with the Father and the angels when one sinner turns and repents. This is why he cries, "I will have mercy, and not sacrifice." — Who is the Rich Man that Shall Be Saved? Cyril of Alexandria : Most of all, worship of God displays love.… For truly the compassion from beside the Father is Christ, as he takes away the sins, dismisses the charges and justifies by faith, and recovers the lost and makes [them] stronger than death. For what is good and he does not give? Therefore the knowledge of God is better than sacrifice and holocausts, as it is brought to perfection in Christ. For by him and in him we have known the Father, and we have become rich in the justification by faith. — COMMENTARY ON Hosea 4:65 Jerome : For I desired mercy, and not sacrifice: and the knowledge of God more than holocausts; but they themselves like Adam have transgressed the covenant: there they have prevaricated against me." LXX: "For I desire mercy, and not sacrifice, and the knowledge of God more than holocausts: but they themselves are like a man passing by the covenant." What follows in the Septuagint: "There hath despised me the city of Galaad, the vain-doer," and the rest, is to be connected with the following chapter: we will discuss what we have proposed: I have grieved them in my prophets, I have slain them with the words of my mouth: I have struck them with hard punishments, so that I might have mercy on the repentant, that I might extend my hand to those who have fallen and risen. For I am not pleased with sacrifices and offerings, and the multitude of burnt offerings. My sacrifice and offerings, the salvation of believers, and the conversion of sinners is. But they imitated Adam, and disregarding my covenant and law, they did on earth what he had done in paradise. And there, that is, in paradise, all have transgressed against me, in the likeness of Adam's transgression. For it is not surprising that what preceded in the parent should also be condemned in their children. Every day God calls those who are outside the Church and those who sin while dwelling in the Church to repentance, and says to them: "I desire mercy, not sacrifice, and knowledge of God rather than holocausts." But they offer sacred bread and give alms, and seem to pursue humility: this I interpret as holocausts, if they are truly done. However, when they have abandoned knowledge of God, they boast in vain of having the rest of the members, with the head of faith cut off, for they have transgressed the covenant of God in the Church, just as Adam transgressed it in Paradise; and they show themselves to be imitators of that ancient parent, so that just as he was cast out of Paradise, so they may also be cast out of the Church. — Commentary on Hosea 6:6-7 John Chrysostom : Great is the principle of mercy to God. Not only his to us, but also that issuing from us to our fellow servants. In the Old Testament and the New, God lays down innumerable laws pertaining to this matter. He orders us to be benevolent continually in all quarters, through words, money and deeds. And Moses throughout—up and down, here and there—scatters words about these matters in all his legislations. And in the person of God the prophets shout, "I desire mercy, and not sacrifice." And all the apostles act and speak in harmony with these prophetic words. Therefore let us not neglect the matter. By mercy we greatly benefit ourselves, not the poor only. We receive much more than we provide. — HOMILIES ON REPENTANCE AND ALMSGIVING 10:5.22 Tertullian : But he would not threaten the impenitent if he failed to pardon the penitent. This would be doubtful only if he had not revealed elsewhere the profusion of his mercy. Has he not said, "He who is fallen shall rise, and he who was turned away shall return"? He it is, most assuredly, who "will have mercy rather than sacrifice." The heavens and the angels who are there rejoice at human repentance. Look at you now, sinner, be of good heart! You see where it is that you are a cause of joy. — ON PENITENCE 8 Theodoret of Cyrus : Whereas I [the Lord] have no need of sacrifices, I accept them out of considerateness for the limitations of your way of thinking. These two things, on the contrary, I do require: the right disposition toward me and lovingkindness toward the neighbor, these also being the first obligations I imposed, "You will love the Lord your God with your whole heart, your whole soul, your whole mind and your whole strength; and you will love your neighbor as yourself." But whereas I imposed these obligations, they resembled someone breaking agreements made by him with somebody else. In similar fashion, in fact, they despised my longsuffering and trampled on the laws given them. — COMMENTARY ON Hosea 6:6–7
