Clement of Rome

Let us turn to every age that has passed, and learn that, from generation to generation, the Lord has granted a place of repentance to all such as would be converted unto Him... Jonah proclaimed destruction to the Ninevites; but they, repenting of their sins, propitiated God by prayer, and obtained salvation, although they were aliens [to the covenant] of God.

These things, dearly beloved, we are writing, not only to warn you but also to remind ourselves; for we are in the same arena, and the same contest lies before us. For this reason let us abandon empty and silly concerns and come to the glorious and holy rule of our tradition. Let us see what is good and pleasing and acceptable in the sight of our Maker. Let us fix our gaze on the blood of Christ and realize how precious it is to his Father, seeing that it was poured out for our salvation and brought the grace of conversion to the whole world. Let us look back over all the generations and learn that from generation to generation the Lord has given an opportunity of repentance to all who would return to him. Noah preached penance, and those who heeded were saved. Then Jonah announced destruction to the Ninevites and they repented of their sins, besought God in prayer and, estranged though they were from God, obtained salvation.
