appointed bishop of a titular see, a see that in the course of history has ceased to exist as an actual jurisdictional unit. Important titles or functions usually, but not necessarily, held by (arch)bishops who are not in charge of a diocese or an equivalent community include those of Apostolic Delegate, Apostolic Nuncio, Papal Legate, Patriarchal Vicar, Pontifical Delegate. Ordinaries and local ordinaries Local ordinaries are placed over or exercise ordinary executive power in particular churches or equivalent communities. The Supreme Pontiff (the Pope) is a local ordinary for the whole Catholic Church. In Eastern Catholic Churches, Patriarchs, major archbishops, and metropolitans have ordinary power of governance for the whole territory of their respective autonomous particular churches.
