"Christ says: Give me this fisherman, this man without education or experience, this man to whom no senator would deign to speak, not even if he were buying fish. Yes, give me him; once I have taken possession of him, it will be obvious that it is I who am at work in him. Although I meant to include senators, orators, and emperors among my recruits, even when I have won over the senator I shall still be surer of the fisherman. The senator can always take pride in what he is; so can the orator and the emperor, but the fisherman can glory in nothing except Christ alone."
You have caught me, O Lord. Now, I pray, make me but your fisherman in the sea of your love. May I use no other hook than the Cross, and no other bait than your grace and truth.
Augustine of Hippo (AD 354-430), Sermo 43, 5-6
Augustine was a daft admirer of classical literature, received some formal training in classical rhetoric and longed to be a professional orator. But he sacrificed that ambition in order to be a priest and bishop for the people of God.
