The Orthodox Church is comprised of various self-governing jurisdictions. Although one might be tempted to think of this in terms of multiple churches, the Orthodox Church is one, for she has one head, Jesus Christ. These jurisdictions are not a hierarchy as with the Roman Catholic church nor are they completely separate groups, but instead are unified in council and communion. They share beliefs and teachings although some forms and ceremonies may differ. The various jurisdictions of the Church are identified by location, frequently the original founding location by the Apostles and early missionaries of the Church.
