c. 96 · Clement of Rome, First Epistle to the Corinthians (1 Clement) 8
The ministers of the grace of God have, by the Holy Spirit, spoken of repentance; and the Lord of all things has himself declared with an oath regarding it, “As I live, saith the Lord, I desire not the death of the sinner, but rather his repentance;” adding, moreover, this gracious declaration, “Repent, O house of Israel, of your iniquity. Say to the children of My people, Though your sins reach from earth to heaven, and though they be redder than scarlet, and blacker than sackcloth, yet if ye turn to Me with your whole heart, and say, Father! I will listen to you, as to a holy people.”
