Let us fix our eyes on the blood of Christ and understand how precious it is to his Father, because, being poured out for our salvation, it won for the whole world the grace of repentance. Let us review all the generations in turn, and learn that from generation to generation the Master has given an opportunity for repentance to those who desire to turn to him. Noah preached repentance, and those who obeyed were saved. Jonah preached destruction to the people of Nineveh; but they, repenting of their sins, made atonement to God by their prayers and received salvation, even though they were alienated from God.
The ministers of the grace of God spoke about repentance through the Holy Spirit; indeed, the Master of the universe himself spoke about repentance with an oath: 'For as I live, says the Lord, I do not desire the death of the sinner, so much as his repentance.' [Cf. Ezek. 33:11]" (The Letter of the Romans to the Corinthians, 7-8; quoted from Lightfoot and Harmer, The Apostolic Fathers, Second Edition, p. 32)
