All within 100 years after Christ’s Resurrection:
We are Saved by Faith and Works, and Not Faith Alone
“Seeing, therefore, that we are the portion of the Holy One, let us do all those things which pertain to holiness, avoiding all evil-speaking, all abominable and impure embraces, together with all drunkenness, seeking after change, all abominable lusts, detestable adultery, and execrable pride. ‘For God,’ saith [the Scripture], ‘resisteth the proud, but giveth grace to the humble.’ Let us cleave, then, to those to whom grace has been given by God. Let us clothe ourselves with concord and humility, ever exercising self-control, standing far off from all whispering and evil-speaking, being justified by our works, and not our words." Clement of Rome, Epistle to the Corinthians, 30 (A.D. 98).
“For what reason was our father Abraham blessed? Was it not because he wrought righteousness and truth through faith?” Clement of Rome, Epistle to the Corinthians, 31 (A.D. 98).
“All these, therefore, were highly honoured, 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.” Clement of Rome, Epistle to the Corinthians, 32 (A.D. 98).
“Now I beseech thee, by the grace with which thou art clothed, to add [speed] to thy course, and that thou ever pray for all men that they may be saved, and that thou demand things which are befitting, with all assiduity both of the flesh and spirit. Be studious of unity, than which nothing is more precious. Bear with all men, even as our Lord beareth with thee. Show patience with all men in love, as [indeed] thou doest. Be steadfast in prayer. Ask for more understanding than that which thou [already] hast. Be watchful, as possessing a spirit which sleepeth not. Speak with every man according to the will of God. Bear the infirmities of all men as a perfect athlete; for where the labour is great, the gain is also great.” Ignatius of Antioch, To Polycarp, 1 (A.D. 110).
“Look ye to the bishop, that God also may look upon you. I will be instead of the souls of those who are subject to the bishop, and the presbyters, and the deacons; with them may I have a portion in the presence of God! Labour together with one another, act as athletes together, run together, suffer together, sleep together, rise together. As stewards of God, and of His household, and His servants, please Him and serve Him, that ye may receive from Him the wages promised. Let none of you be rebellious. Let your baptism be to you as armour, and faith as a spear, and love as a helmet, and patience as a panoply. Let your treasures be your good works, that ye may receive the gift of God, as is just. Let your spirit be long-suffering towards each other with meekness, even as God is toward you. As for me, I rejoice in you at all times.” Ignatius of Antioch, To Polycarp, 6 (A.D. 110).
“For he who keepeth these shall be glorified in the kingdom of God; but he who chooseth other things shall be destroyed with his works.” Epistle of Barnabas, 2 (A.D. 132).
“But He who raised Him up from the dead will raise up us also, if we do His will, and walk in His commandments, and love what He loved, keeping ourselves from all unrighteousness, covetousness, love of money, evil speaking, falsewitness; ‘not rendering evil for evil, or railing for railing,’ or blow for blow, or cursing for cursing, but being mindful of what the Lord said in His teaching: ‘Judge not, that ye be not judged; forgive, and it shall be forgiven unto you; be merciful, that ye may obtain mercy; with what measure ye mete, it shall be measured to you again; and once more, "Blessed are the poor, and those that are persecuted for righteousness’ sake, for theirs is the kingdom of God.’” Polycarp, To the Philippians, 2 (A.D. 135).
