ecclesiastical province

An ecclesiastical province is one of the basic forms of jurisdiction in Christian churches, including those of both Western Christianity and Eastern Christianity, that have traditional hierarchical structures. An ecclesiastical province consists of several dioceses (or eparchies), one of them being the archdiocese (or archeparchy), headed by a metropolitan bishop or archbishop who has ecclesiastical jurisdiction over all other bishops of the province.

In the Greco-Roman world, ecclesia (Ancient Greek: ἐκκλησία; Latin: ecclesia) was used to refer to a lawful assembly, or a called legislative body. As early as Pythagoras, the word took on the additional meaning of a community with shared beliefs. This is the meaning taken in the Greek translation of the Hebrew Scriptures (the Septuagint), and later adopted by the Christian community to refer to the assembly of believers.
