Catholic Church Hierarchy - Bishop

Bishop

The bishops, who possess the fullness of the priesthood, are as a body (the College of Bishops) considered the successors of the Apostles and are "constituted Pastors in the Church, to be the teachers of doctrine, the priests of sacred worship and the ministers of governance" and "represent the Church." The Pope himself is a bishop (the bishop of Rome) and traditionally uses the title "Venerable Brother" when writing formally to another bishop.

The typical role of a bishop is to provide pastoral governance for a diocese. Bishops who fulfill this function are known as diocesan ordinaries, because they have what canon law calls ordinary (i.e. not delegated) authority for a diocese. These bishops may be known as hierarchs in the Eastern Catholic Churches. Other bishops may be appointed to assist ordinaries (auxiliary bishops and coadjutor bishops) or to carry out a function in a broader field of service to the Church, such as appointments as papal nuncios or as officials in the Roman Curia.

Bishops of a country or region may form an episcopal conference and meet periodically to discuss current problems. Decisions in certain fields, notably liturgy, fall within the exclusive competence of these conferences. The decisions of the conferences are binding on the individual bishops only if agreed to by at least two-thirds of the membership and confirmed by the Holy See.

Bishops are normally ordained to the episcopate by at least three other bishops, though for validity only one is needed and a mandatum from the Holy See is required. Ordination to the episcopate is considered the completion of the sacrament of Holy Orders; even when a bishop retires from his active service, he remains a bishop, since the ontological effect of Holy Orders is permanent. On the other hand, titles such as archbishop or patriarch imply no ontological alteration, and existing bishops who rise to those offices do not require further ordination.

Among bishops, various ranks are distinguished. The Pope, as the successor of Saint Peter, is the head of the universal Catholic Church and of the Latin Church. Some of the Eastern Catholic churches are headed by a patriarch, a major archbishop, or a metropolitan. Within the Latin Church too, dioceses are normally grouped together as ecclesiastical provinces, in which the bishop of a particular see has the title of metropolitan archbishop, with some very limited authority for the other dioceses, which are known as suffragan sees.
