Ecclesiastical jurisdictionEcclesiastical jurisdiction signifies jurisdiction by church leaders over other church leaders and over the laity. Jurisdiction is a word borrowed from the legal system which has acquired a wide extension in theology, wherein, for example, it is frequently used in contradistinction to order, to express the right to administer sacraments as something added onto the power to celebrate them. So it is used to express the territorial or other limits of ecclesiastical, executive or legislative authority.
Quinisext CouncilThe Quinisext Council (Concilium Quinisextum; Penthékti Sýnodos), i.e., the Fifth-Sixth Council, often called the Council in Trullo, Trullan Council, or the Penthekte Synod, was a church council held in 692 at Constantinople under Justinian II. It is known as the "Council in Trullo" because, like the Sixth Ecumenical Council, it was held in a domed hall in the Imperial Palace (τρούλος [] meaning a cup or dome). Both the Fifth and the Sixth Ecumenical Councils had omitted to draw up disciplinary canons, and as this council was intended to complete both in this respect, it took the name of Quinisext.
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.
Code of Canons of the Eastern ChurchesThe Code of Canons of the Eastern Churches (CCEC; Codex Canonum Ecclesiarum Orientalium, abbreviated CCEO) is the title of the 1990 work which is a codification of the common portions of the canon law for the 23 Eastern Catholic Churches in the Catholic Church. It is divided into 30 titles and has a total of 1546 canons. The code entered into force in 1991. The western Latin Church is governed by its own particular code, the 1983 Code of Canon Law.
