Clement of Rome (?-110), “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." (The First Epistle of Clement to the Corinthians, Chapter 32).
Polycarp (69-150), "by grace ye are saved, not of works,' but by the will of God through Jesus Christ . . . If we please Him in this present world, we shall receive also the future world, according as He has promised to us that He will raise us again from the dead, and that if we live worthily of Him, 'we shall also reign together with Him,' provided only we believe . . . " (Epistle to the Philippians, 1, 5, 8)
Marius Victorinus (280-?): 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.
