1 Corinthians 4:1

Let a man so account of us, as of ministers of Christ, and stewards of the mysteries of God. [Paul here gives the rule by which apostles and evangelists are to be estimated. They are not to be magnified, for they are servants, nor are they to be deprecated because of the value and importance of that which is entrusted to them as stewards. The term "ministers" here means literally under-rowers. The church is a ship, or galley; Christ is the chief navigator, or magisterium; and all the evangelists and teachers are mere oarsmen with no ambition to be leaders. In the second figure the church is a household, God is the householder, the gospel truths are the food and other provisions which are dispensed by the evangelists or stewards.]
