Mathetes to Diognetus: “He Himself took on Him the burden of our iniquities, He gave His own Son as a ransom for us, the holy One for transgressors, the blameless One for the wicked, the righteous One for the unrighteous, the incorruptible One for the corruptible, the immortal One for them that are mortal. For what other thing was capable of covering our sins than His righteousness? By what other one was it possible that we, the wicked and ungodly, could be justified, than by the only Son of God? O sweet exchange (substitution)! O unsearchable operation! O benefits surpassing all expectation! that the wickedness of many should be hid in a single righteous One, and that the righteousness of One should justify many transgressors! Having therefore convinced us in the former time that our nature was unable to attain to life, and having now revealed the Savior who is able to save even those things which it was [formerly] impossible to save, by both these facts He desired to lead us to trust in His kindness, to esteem Him our Nourisher, Father, Teacher, Counselor, Healer, our Wisdom, Light, Honor, Glory, Power, and Life, so that we should not be anxious concerning clothing and food.” Ante-Nicene Fathers: Volume I, Mathetes to Diognetus, Chapter 9.
Marius Victorinus (born c. 280, converted around 356): Every mystery which is enacted by our Lord Jesus Christ asks only for faith. The mystery was enacted at that time for our sake and aimed at our resurrection and liberation, should we have faith in the mystery of Christ and in Christ. For the patriarchs prefigured and foretold that man would be justified from faith. Therefore, just as it was reckoned as righteousness to Abraham that he had faith, so we too, if we have faith in Christ and every mystery of his, will be sons of Abraham. Our whole life will be accounted as righteous. Epistle to the Galatians, 1.3.7. Mark J. Edwards, ed., Ancient Christian Commentary on Scripture, New Testament VI: Galatians, Ephesians, Philippians (Downers Grove: InterVarsity Press, 1998), p. 39.
Chrysostom (349-407): The patriarch Abraham himself before receiving circumcision had been declared righteous on the score of faith alone: before circumcision, the text says, “Abraham believed God, and credit for it brought him to righteousness.” Fathers of the Church, Vol. 82, Homilies on Genesis 18-45, 27.7 (Washington, D.C.: The Catholic University of America Press, 1990), p. 167.
Chrysostom (349-407): For if even before this, the circumcision was made uncircumcision, much rather was it now, since it is cast out from both periods. But after saying that “it was excluded,” he shows also, how. How then does he say it was excluded? “By what law? of works? Nay, but by the law of faith.” See he calls the faith also a law delighting to keep to the names, and so allay the seeming novelty. But what is the “law of faith?” It is, being saved by grace. Here he shows God’s power, in that He has not only saved, but has even justified, and led them to boasting, and this too without needing works, but looking for faith only. NPNF1: Vol. XI, Homilies on the Epistle of Paul the Apostle to the Romans, Homily 7, vs. 27.
Chrysostom (349-407): “For a person who had no works, to be justified by faith, was nothing unlikely. But for a person richly adorned with good deeds, not to be made just from hence, but from faith, this is the thing to cause wonder, and to set the power of faith in a strong light.” NPNF1: Vol. XI, Homilies on the Epistle of Paul the Apostle to the Romans, Homily 8, Rom. 4:1, 2.
Chrysostom (349-407): “And this he removes, with great skill and prudence, turning their argument against themselves, and showing that those who relinquish the Law are not only not cursed, but blessed; and they who keep it, not only not blessed but cursed. They said that he who kept not the Law was cursed, but he proves that he who kept it was cursed, and he who kept it not, blessed. Again, they said that he who adhered to Faith alone was cursed, but he shows that he who adhered to Faith alone, is blessed. And how does he prove all this? for it is no common thing which we have promised; wherefore it is necessary to give close attention to what follows.” NPNF1: Vol. XIII, Commentary on Galatians, 3:8.
Chrysostom (349-407): “For they said that the one who does not keep the law is cursed, while he shows that the one who strives to keep it is cursed and the one who does not strive to keep it is blessed. They said that he who kept not the Law was cursed, but he proves that he who kept it was cursed, and he who kept it not, blessed. Again, they said that he who adhered to Faith alone was cursed, but he shows that he who adhered to Faith alone, is blessed.” Homily on Galatians 3.9-10. Mark J. Edwards, ed., Ancient Christian Commentary on Scripture, New Testament VI: Galatians, Ephesians, Philippians (Downers Grove: InterVarsity Press, 1998), p. 40. 3:8.
Chrysostom (349-407): God’s mission was not to save people in order that they may remain barren or inert. For Scripture says that faith has saved us. Put better: Since God willed it, faith has saved us. Now in what case, tell me, does faith save without itself doing anything at all? Faith’s workings themselves are a gift of God, lest anyone should boast. What then is Paul saying? Not that God has forbidden works but that he has forbidden us to be justified by works. No one, Paul says, is justified by works, precisely in order that the grace and benevolence of God may become apparent. Homily on Ephesians 4.2.9. Mark J. Edwards, ed., Ancient Christian Commentary on Scripture, New Testament VI: Galatians, Ephesians, Philippians (Downers Grove: InterVarsity Press, 1998), p. 134.
