Diocesan Bishops or Eparchs
See also: Ordinary (officer) and Diocesan bishopThe traditional role of a bishop is to act as head of a diocese or eparchy. Dioceses vary considerably in geographical size and population. A wide variety of dioceses around the Mediterranean Sea which received the Christian faith early are rather compact in size, while those in areas more recently evangelized, as in some parts of Sub-Saharan Africa, South America and the Far East, tend to be much larger and more populous. Within his own diocese a Latin Church bishop may use pontifical vestments and regalia, but may not do so in another diocese without, at least, the presumed consent of the appropriate ordinary.
