Peter Chrysologus

Paul introduces a new kind of admonition by exhorting others “by the mercy of God.” Why does he not exhort through God’s might, or majesty, or glory? Why by his mercy? Because it was through that mercy alone that Paul escaped from the criminal state of a persecutor and obtained the dignity of his great apostolate. He himself tells us this, “For I formerly was a blasphemer, a persecutor and a bitter adversary; but I obtained the mercy of God.” … “I exhort you by the mercy of God.” Paul asks—rather, God himself is asking through Paul—for God has greater desire to be loved than feared. God is asking because he wants to be not so much a Lord as a Father.
