eparchy

Eparchy ( eparchía "overlordship") is an ecclesiastical unit in Eastern Christianity that is equivalent to a diocese in Western Christianity. An eparchy is governed by an eparch, who is a bishop. Depending on the administrative structure of a specific Eastern Church, an eparchy can belong to an ecclesiastical province (usually a metropolis), but it can also be exempt. Each eparchy is divided into parishes, in the same manner as a diocese in Western Churches. Historical development of eparchies in various Eastern Churches was marked by local distinctions that can be observed in modern ecclesiastical practices of the Eastern Orthodox Church, Oriental Orthodox Churches and Eastern Catholic Churches.

==Terminology== The English word eparchy is an anglicized term that comes from the original Greek word (, ). It is an abstract noun, formed with an intensive prefix (, , + , , ). It is commonly Latinized as eparchia. The term can be loosely translated as the rule over something (literally: an overlordship). The term had various meanings and multiple uses throughout history, mainly in politics and administration, starting from the Hellenistic period, and continuing throughout the Roman era.
