In the New Testament, a presbyter (Greek πρεσβύτερος: "elder") is a leader of a local Christian congregation. The word derives from the Greek presbyteros, which means elder or senior. The Greek word episkopos literally means overseer; it refers exclusively to the office of bishop. Many understand presbyteros to refer to the bishop functioning as overseer. In modern Catholic and Orthodox usage, presbyter is distinct from bishop and synonymous with priest. In predominant Protestant usage, presbyter does not refer to a member of a distinctive priesthood called priests, but rather to a minister, pastor, or elder.
