CatholicosA catholicos (plural: catholicoi) is the head of certain churches in some Eastern Christian traditions. The title implies autocephaly and, in some cases, it is the title of the head of an autonomous church. The word comes from ancient Greek καθολικός ( () καθολικοί), derived from καθ' ὅλου (, "generally") from κατά (, "down") and ὅλος (, "whole"), meaning "concerning the whole, universal, general"; it originally designated a financial or civil office in the Roman Empire.

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.
PhyletismPhyletism or ethnophyletism (from ethnos and φυλετισμός, , 'tribalism') is the principle of nationalities applied in the ecclesiastical domain: in other words, the conflation between church and nation. The term ethnophyletism designates the idea that a local autocephalous church should be based not on a local (ecclesial) criterion, but on an ethnophyletist, national or linguistic one.
