“Now the main thing in a preacher should be that he may speak, not with his mouth merely, but by his life, and procure authority for his doctrine by rectitude of life. Paul, accordingly, procures authority for his exhortation on this ground, that he had, by his life no less than by his mouth, been a leader and a master of virtues.”
–John Calvin, commenting on Philippians 4:9 in Commentaries on the Epistles of Paul to the Galatians and Ephesians, trans. William Pringle (Grand Rapids: Baker, 2005), 122.
