In the
Church of England and many other Anglican churches a deanery is a group of
parishes forming a district within an
archdeaconry. The more formal term,
rural deanery, is less often used, though the superintendent of a deanery is the
Rural Dean. Rural deaneries are very ancient and originally corresponded with the
hundreds. The title "dean" (Latin
decanus) may derive from the custom of dividing a hundred into ten
tithings. In medieval times rural deans acted as officers of the diocesan
bishop, but
archdeacons gradually took over most of their duties. However, the office was revived during the 19th century. Modifications to deanery boundaries may be made according to the provisions of the
Archdeaconries and Rural Deaneries Act 1874 (
37 & 38 Vict. c. 63). The
deanery synod has a membership of all clergy who are licensed to a parish within the deanery, plus elected lay members from every parish. They were established in the 1970s. The term is also often used to refer to the house, or official residence, of the dean of a cathedral. The term is also used to apply to the ecclesiastical districts of
Jersey and
Guernsey, which are
Royal Peculiars and whose deans hold a status more nearly equivalent to an
Archdeacon than a rural dean. In the
Episcopal Church, deaneries are synonymous with convocations and are headed by deans. == Eastern Orthodox usage ==
