Clement of Alexandria : Isaiah says [about Christ], "The Lord has laid on him the iniquity of us all," that is, to correct our iniquities and set them right. For that reason, he alone is able to forgive our sins, he who has been appointed by the Father of all as our educator, for he alone is able to separate obedience from disobedience. — The Instructor Book 1 Jerome : All we like sheep have gone astray; we have turned every one to his own way; and the Lord hath laid on him the iniquity of us all. All, as it is said, have gone astray like sheep, and we are in need of God's mercy, saying in the psalm: I have strayed like a lost sheep (Ps. CXVIII, 176); which in the parable of the Good Shepherd in the Gospel was carried on his concerned shoulders (Matth. XV). But the following verse shows who these sheep are. Man has wandered in his way; or rather, each one has turned aside in his own way, in order to follow his own error, abandoning the right path, and thinking differently about the Crucified. However, the Lord placed on him the iniquity of all of us, or he handed him over for our sins; so that what we could not bear on account of our weakness, he would bear for us, who was offered, because he himself willed it. — Commentary on Isaiah Theodore of Heraclea : He bore the sum of human evils and every form of transgression, as well as their recompense and punishment. And as if he were our debtor, the only-begotten Word of God, coming into the world alongside us, fulfilled every law and all righteousness and did not stumble over sin but received it willingly so as to change our punishment into peace and harmony. For undergoing temptation he carried our rebukes and punishments, and by faith we make our own his sufferings, and dying together with him we are saved by grace. He was not delivered by force but as an act of obedience. — FRAGMENTS ON ISAIAH Theodoret of Cyrus : The offenses of all were not equal, and there was not only one way of being impious; for the idols of the Egyptians and those of the Phoenicians were not the same, those of the Greeks were different, and those of the Scythians were something else. Nevertheless, although the forms of error were different, we had all in a common manner abandoned the true God, and by this we resembled sheep who have gone astray and are exposed to the wolves. — COMMENTARY ON Isaiah 17:53.6
