The Archdeacon's Administrative Oversight

An archdeacon assists a diocesan bishop by overseeing a defined territorial subdivision of the diocese, the archdeaconry, with particular responsibility for the condition of church buildings and clergy housing, the conduct of parish visitations, and a range of routine administrative and disciplinary matters a bishop would otherwise have to handle personally across the whole diocese; the office is sometimes summarized in Anglican usage through the archaic phrase the bishop's eye, capturing its function as an extension of episcopal oversight into the diocese's day-to-day administration rather than an independent governing authority in its own right.

The archdeaconry as a territorial unit predates much of the rest of the modern diocesan administrative structure in English church history, with the office attested from at least the twelfth century as dioceses, particularly the larger medieval English ones, found they needed an intermediate tier of oversight between the bishop and the individual parish clergy; the office has persisted through the Reformation and into the modern Church of England largely unchanged in its basic administrative character, even as the surrounding diocesan bureaucracy around it has grown considerably more elaborate.
