Metochion

A metochion or metochi ( or ; ) is an ecclesiastical embassy church within Eastern Orthodox tradition. It is usually from one autocephalous or autonomous church to another. The term is also used to refer to a parish representation (or dependency) of a monastery or a patriarch.
Ecclesiastical Embassy Church.
In the former case, the local territorial church grants a plot of land or a church building for the use of the foreign church being represented, and the location is then considered to belong canonically to the foreign church. Services held there are often in the language appropriate to the church being represented, and the congregation is often made up of immigrants or visitors from the nation associated with that church. Typically, a "metochion" presence on the territory of an autocephalous church is limited to only a few parishes at most.
Dependency of a monastery.
In the case of a monastic "metochion", such a parish church is a dependency of a particular monastic community, perhaps receiving clergy from that community or other forms of support. During the Byzantine era, a monastic "metochion" may have been property granted to a monastery for income purposes.
"Metochion" is currently employed, as well, to refer to a dependent monastery, skete, kellion or monastic society that is being given the blessing and support to develop into an autonomous monastery, skete, kellion or society. For an example, "Wawasinno Ki'chi Wa Mali'i Waabanowigaan"—the "Hesychastic Society of the Most Holy Mary"—is a Canadian Orthodox hesychastic society founded for (but not to be exclusively of) Aboriginal Orthodox, and which is classified as a metochion of the Monastic Society of St. Silouan the Athonite (OCA, Archdiocese of Canada).
