Encyclopedia Article for diocese

in some Christian churches, a territorial area administered by a bishop. The word originally referred to a governmental area in the Roman Empire, governed by an imperial vicar. The secular diocese was subdivided into provinces, each with its own governor; but, in the ecclesiastical adaptation of the system, the province became the larger territorial unit, administered by a metropolitan bishop and subdivided into dioceses.
