The Church of Greece (
Greek: Ekklēsía tês Helládos,
IPA: /ekli'sia tis e'laðos/) is one of the fifteen
autocephalous Eastern Orthodox churches which make up the
Eastern Orthodox Communion. Today it is one of the most important autocephalous, or ecclesiastically independent, churches of the Eastern Orthodox communion. Its canonical territory encompasses the pre-1833 borders of Greece, approximately half of Greek territory (the rest of Greece is subject to the
Ecumenical Patriarchate in Constantinople, however due to an arrangement agreed between the churches of Athens and Constantinople, most of those dioceses are de facto administered as part of the Church of Greece for practical reasons).
