A bishop is a senior church leader in Christian traditions that use an episcopal form of governance. The title comes from a Greek word meaning “overseer.” Catholic, Eastern Orthodox, Oriental Orthodox, Anglican, and several Protestant churches have bishops, but their authority and method of appointment differ.
Bishops in the early church
The New Testament uses terms translated as overseer, elder, and presbyter in ways that do not map neatly onto every later church office. By the second century, many Christian communities show a clearer pattern in which a bishop presided with presbyters and deacons.
Bishops in the Catholic Church
Catholic teaching regards bishops as successors of the apostles. Canon law describes them as pastors with responsibilities for teaching doctrine, sacred worship, and governance. A diocesan bishop is entrusted with a diocese; auxiliary and coadjutor bishops assist in different ways, while titular bishops hold a title to a historical see without governing it as a current diocese.
Bishops receive episcopal ordination. In the Latin Catholic Church, the pope appoints bishops or confirms those legitimately elected according to church law.
Bishops in Orthodox and Anglican churches
Eastern and Oriental Orthodox churches also understand bishops within apostolic succession and sacramental ministry. Bishops normally oversee dioceses or eparchies and ordain clergy.
Anglican churches retain the historic episcopate, but governance differs among provinces. Bishops may be elected, appointed, or selected through mixed procedures depending on the church.
Bishops in Protestant denominations
Some Lutheran, Methodist, Pentecostal, and other Protestant bodies use the title bishop. In these traditions the office may involve regional supervision, ordination, administration, or pastoral leadership, but it is not defined identically across denominations.
Bishop, archbishop, cardinal, and pope
An archbishop is normally a bishop associated with an archdiocese or a wider coordinating role. A cardinal is a Catholic dignity appointed by the pope and is not a separate sacramental order. The pope is the Bishop of Rome and, in Catholic teaching and law, holds the highest office in the Catholic Church.
Because Christian structures vary, “bishop” should not be described as though every church gives the office the same powers. The common idea is oversight; the theological meaning and practical authority depend on the tradition.
What is a diocese?
A diocese is a territorial or personal church community entrusted to a bishop in traditions that use diocesan structures. In Eastern Catholic and Orthodox settings, a comparable jurisdiction may be called an eparchy. The bishop normally works with priests, deacons, lay leaders, and administrative bodies rather than governing alone.
How are bishops chosen?
Selection varies by church. In the Latin Catholic Church, the pope appoints bishops after a confidential consultation process. Eastern Catholic churches have procedures involving synods and papal authority. Orthodox churches normally choose bishops through their synods. Anglican and Protestant systems may use election, appointment, or a combination of methods.
What can only a bishop do?
In Catholic and Orthodox sacramental practice, bishops have a distinctive role in ordination and in maintaining communion among local churches. Some functions can be delegated or shared according to church law, while others are tied closely to episcopal ordination. Anglican and Protestant practice varies.
