You mean like these guys?Because God didn't reveal it. It is a Protestant invention.
Clement of Rome (Fl. 96): Whosoever will candidly consider each particular, will recognize the greatness of the gifts which were given by him. For from him have sprung the priests and all the Levites who minister at the altar of God. From him also [was descended] our Lord Jesus Christ according to the flesh. From him [arose] kings, princes, and rulers of the race of Judah. Nor are his other tribes in small glory, inasmuch as God had promised, “Thy seed shall be as the stars of heaven.” All these, therefore, were highly honored, and made great, not for their own sake, or for their own works, or for the righteousness which they wrought, but through the operation of His will. And we, too, being called by His will in Christ Jesus, are not justified by ourselves, nor by our own wisdom, or understanding, or godliness, or works which we have wrought in holiness of heart; but by that faith through which, from the beginning, Almighty God has justified all men; to whom be glory for ever and ever. Amen. ANF: Vol. I, The Apostolic Fathers, First Epistle of Clement to the Corinthians, Chapter 32.
Mathetes to Diognetus: As long then as the former time endured, He permitted us to be borne along by unruly impulses, being drawn away by the desire of pleasure and various lusts. This was not that He at all delighted in our sins, but that He simply endured them; nor that He approved the time of working iniquity which then was, but that He sought to form a mind conscious of righteousness, so that being convinced in that time of our unworthiness of attaining life through our own works, it should now, through the kindness of God, be vouchsafed to us; and having made it manifest that in ourselves we were unable to enter into the kingdom of God, we might through the power of God be made able. But when our wickedness had reached its height, and it had been clearly shown that its reward, punishment and death, was impending over us; and when the time had come which God had before appointed for manifesting His own kindness and power, how the one love of God, through exceeding regard for men, did not regard us with hatred, nor thrust us away, nor remember our iniquity against us, but showed great long-suffering, and bore with us, 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.
Basil of Caesarea (Ad 329-379): [As the Apostle says,] Let him who boasts boast in the Lord, [I say that] Christ has been made by God for us righteousness, wisdom, justification, [and] redemption, that, as it is written, “he who boasts, let him boast in the Lord.” [For] this is perfect and pure boasting in God, when one is not proud on account of his own righteousness but knows that he is indeed unworthy of the true righteousness and is (or has been, δεδικαιωμένον, perfect passive participle, accusative, masculine of δικαιόω) justified solely by faith in Christ. See Chemnitz, Examination of the Council of Trent, Part 1, trans. Fred Kramer (St. Louis: Concordia Publishing House, 1971), p. 505.
Chrysostom (349-407): What does he mean when he says: “I have declared your justice?” He did not simply say: “I have given,” but “I have declared.” What does this mean? That he has justified our race not by right actions, not by toils, not by barter and exchange, but by grace alone. Paul, too, made this clear when he said: “But now the justice of God has been made manifest independently of the Law.” But the justice of God comes through faith in Jesus Christ and not through any labor and suffering. FC, Vol. 68, Discourses Against Judaizing Christians, Disc. 7.3.2 (Washington, D.C.: The Catholic University of America Press, 1979), pp. 186-187.
Augustine (354-430): But what about the person who does no work (Rom 4:5)? Think here of some godless sinner, who has no good works to show. What of him or her? What if such a person comes to believe in God who justifies the impious? People like that are impious because they accomplish nothing good; they may seem to do good things, but their actions cannot truly be called good, because performed without faith. But when someone believes in him who justifies the impious, that faith is reckoned as justice to the believer, as David too declares that person blessed whom God has accepted and endowed with righteousness, independently of any righteous actions (Rom 4:5-6). What righteousness is this? The righteousness of faith, preceded by no good works, but with good works as its consequence. John E. Rotelle, O.S.A., ed., The Works of Saint Augustine, Part 1, Vol. 11, trans. Maria Boulding, O.S.B., Expositions of the Psalms 1-32, Exposition 2 of Psalm 31, §7 (Hyde Park: New City Press, 2000), p. 370.
Didymus the Blind (c. 313-398): But how can some say that because the spirit which gives life to the body is more honorable than the body, therefore works are more honorable than faith? I have looked into this matter in some detail and shall try to explain my position on this. It is undoubtedly true that the spirit is nobler than the body, but this does not mean that works can be put before faith, because a person is saved by grace, not by works but by faith. There should be no doubt but that faith saves and then lives by doing its own works, so that the works which are added to salvation by faith are not those of the law but a different kind of thing altogether. Gerald Bray, ed., Ancient Christian Commentary on Scripture: New Testament, Vol. XI, James, 1-2 Peter, 1-3 John, Jude (Downers Grove: InterVarsity Press, 2000), p. 34. See PG 39:1732, from his Commentary on James, 2:26b.
Fulgentius, bishop of Ruspe (c. 467-532) commenting on Eph. 2:8a: The blessed Paul argues that we are saved by faith, which he declares to be not from us but a gift from God. Thus there cannot possibly be true salvation where there is no true faith, and, since this faith is divinely enabled, it is without doubt bestowed by his free generosity. Where there is true belief through true faith, true salvation certainly accompanies it. Anyone who departs from true faith will not possess the grace of true salvation. On the Incarnation, 1. Mark J. Edwards, ed., Ancient Christian Commentary on Scripture, New Testament VI: Galatians, Ephesians, Philippians (Downers Grove: InterVarsity Press, 1998), pp. 133-134.
