The Ancients
Theophilus of Antioch
“For he who gave the mouth for speech, and formed the ear to hear, and made the eye to see, will examine all things, and will judge righteous judgment, rendering merited awards to each. To those who by patient continuance in well-doing [Rom 2:7] seek immortality, he will give life everlasting, joy, peace, rest, and abundance of good things, which neither has eye seen, nor ear heard, nor has it entered into the heart of man to conceive [1 Cor 2:9]. But to the unbelieving and despisers, who obey not the truth, but are obedient to unrighteousness, when they have been filled with adulteries and fornications, and filthiness, and covetousness, and unlawful idolatries, there shall be anger and wrath, tribulation and anguish [Rom 2:8–9], and at the last everlasting fire shall possess such men [To Autolycus 1:14 (c. A.D. 181)].
Clement of Alexandria
“So that when we hear, "Thy faith hath saved thee, we do not understand Him to say absolutely that those who have believed in any way whatever shall be saved, unless also works follow. But it was to the Jews alone that He spoke this utterance, who kept the law and lived blamelessly, who wanted only faith in the Lord. No one, then, can be a believer and at the same time be licentious; but though he quit the flesh, he must put off the passions, so as to be capable of reaching his own mansion.” [Stromata 6:14 (c. A.D. 202)].
Hippolytus of Rome
“And again, it is said, the Saviour has declared, Not every one that says unto me, Lord, Lord, shall enter into the kingdom of heaven, but he that does the will of my Father which is in heaven. [Matthew 7:21] And it is necessary that they who perform this (will), not hear it merely, should enter into the kingdom of heaven” [Refutation of All Heresies 5:2 (A.D. 225)].
Cyprian of Carthage
“You, then, who are rich and wealthy, buy for yourself from Christ gold purified in fire, for with your filth, as if burned away in the fire; you can be like pure gold, if you are cleansed by almsgiving and by works of justice. Buy yourself a white garment so that, although you had been naked like Adam and were formerly frightful and deformed, you may be clothed in the white garment of Christ. You who are a matron rich and wealthy, anoint not your eyes with the antimony of the devil, but with the salve of Christ, so that you may at last come to see God, when you have merited before God both by your works and by your manner of living” [Works and Almsgiving (Treatise 8) 14 (A.D. 253)].
