Presbyter (Greek πρεσβύτερος: "elder") in the New Testament refers to a leader in local Christian congregations, with presbyter being from the Greek "presbyteros" and meaning elder/senior. The word episkopos means (literally) overseer, referring exclusively to the office of bishop. Presbyteros is understood by many as referring to the same person functioning as overseer. In modern Catholic and Orthodox usage, presbyter is distinct from bishop and synonymous with priest. In predominant Protestant usage, the term is not used to refer to a member of a distinctive priesthood called priests, but instead terms such as minister, pastor and elder are used.
The word presbyter etymologically derives from Greek πρεσβύτερος (presbyteros), the comparative form of πρέσβυς (presbys), "old man". However, while the English word priest has presbyter as the etymological origin, the distinctive Greek word for "priest" is never used for presbyteros/episkopos in the New Testament, except as being part of the general priesthood of all believers, with the first Christians making a distinction between sacerdotal Jewish and pagan priests and New Testament pastors.
The earliest organization of the Church in Jerusalem was according to most scholars similar to that of Jewish synagogues, but it had a council or college of ordained presbyters (Greek: πρεσβύτεροι elders). In Acts 11:30 and Acts 15:22, we see a collegiate system of government in Jerusalem though headed by James, according to tradition the first bishop of the city. In Acts 14:23, the Apostle Paul ordains presbyters in the churches he founded.
