Episcopal seeAn episcopal see is, in a practical use of the phrase, the area of a bishop's ecclesiastical jurisdiction. Phrases concerning actions occurring within or outside an episcopal see are indicative of the geographical significance of the term, making it synonymous with diocese. The word see is derived from Latin sedes, which in its original or proper sense denotes the seat or chair that, in the case of a bishop, is the earliest symbol of the bishop's authority. This symbolic chair is also known as the bishop's cathedra.
Canonical territoryA canonical territory is, in some Christian denominations, a geographical area seen as belonging to a particular bishop or Church as its own when it comes to ecclesiastical matters, whether by tradition or by canon law. The concept is found both in the Eastern Orthodox Church and Catholic Church. According to Andriy Mykhaleyko, the expression "canonical territory" is "rather difficult to define as it can refer to a variety of different aspects, from an ecclesiological, geographical, and cultural entity to the territorial or canonical jurisdiction of a church as an expression of its local community, or the pastoral theological care of the faithful in a particular territory.
History of the Eastern Orthodox ChurchThe History of the Eastern Orthodox Church is the formation, events, and transformation of the Eastern Orthodox Church through time. According to the Eastern Orthodox tradition the history of the Eastern Orthodox Church is traced back to Jesus Christ and the Apostles. The Apostles appointed successors, known as bishops, and they in turn appointed other bishops in a process known as Apostolic succession. Over time, five Patriarchates were established to organize the Christian world, and four of these ancient Patriarchates remain Orthodox today.
