The office of the minister is first in the Church, both for dignity and usefulness. The person who fills the office has, in Scripture, obtained different names expressive of his various duties. As he has the oversight of the flock of Christ, he is termed bishop. As he feeds them with spiritual food, he is termed pastor. As he serves Christ in his Church, he is termed minister. As it is his duty to be grave and prudent, and an example of the flock, and to govern well in the house and kingdom of Christ, he is termed presbyter or elder. As he is sent to declare the will of God to sinners, and to beseech them to be reconciled to God through Christ, he is termed ambassador. And, as he dispenses the manifold grace of God, and the ordinances instituted by Christ, he is termed steward of the mysteries of God, and in humility he is the servant of Christ, separated unto the Gospel of God.
