A prelate (ˈpɹɛlət) is a high-ranking member of the Christian clergy who is an ordinary or who ranks in precedence with ordinaries. The word derives from the Latin praelatus, the past participle of praeferre, which means 'carry before', 'be set above or over' or 'prefer'; hence, a prelate is one set over others.
The archetypal prelate is a bishop, whose prelature is his particular church. All other prelates, including the regular prelates such as abbots and major superiors, are based upon this original model of prelacy.
In a general sense, a "prelate" in the Roman Catholic Church and other Christian churches is a bishop or other ecclesiastical person who possesses ordinary authority of a jurisdiction, i.e., of a diocese or similar jurisdiction, e.g., ordinariates, apostolic vicariates/exarchates, or territorial abbacies. It equally applies to cardinals, who enjoy a kind of "co-governance" of the church as the most senior ecclesiastical advisers and moral representatives of the Supreme Pontiff, and certain "superior prelates of the offices of the Roman Curia" who are not bishops, e.g., the auditors (judges) of the Roman Rota and protonotaries apostolic. By extension, it refers to "inferior" or "lesser prelates", that is priests who have the title and dress of prelates as a personal honorific, i.e., Papal chaplains, prelates of honor (formerly "domestic prelates"), and honorary protonotaries apostolic. All these enjoy the title of "monsignor", which also is used in some nations for bishops and archbishops. The seven de numero protonotaries apostolic in Rome, who are special Papal notaries, are true prelates like bishops; others are "supernumerary" protonotaries apostolic who enjoy this as an honorific, like Papal chaplains and prelates of honor.
In the strict canonical sense, "prelate" denominates a priest or bishop who is ordinary of a personal prelature (see below), which is a functional equivalent of a diocese that has a "particular pastoral or missionary work for various regions or for different social groups" (cf.
