An exarchate is any territorial jurisdiction (secular or ecclesiastical) whose ruler is described as an exarch.
The highest-ranking bishops in Eastern Orthodoxy, Oriental Orthodoxy, the Catholic Church, and the Church of the East are termed patriarchs.
The term exarch comes from the Ancient Greek ἔξαρχος, exarchos, and designates holders of various historical offices, some of them being political or military and others being ecclesiastical.
Sui iuris, also spelled as sui juris, is a Latin phrase that literally means "of one's own right". It is used in both civil law and canon law by the Catholic Church. The term church sui iuris is used in the Catholic Code of Canons of the Eastern Churches (CCEO) to denote the autonomous churches in Catholic communion:
A church sui iuris is "a community of the Christian faithful, which is joined together by a hierarchy according to the norm of law and which is expressly or tacitly recognized as sui iuris by the supreme authority of the Church" (CCEO.27). The term sui iuris is an innovation of the CCEO, and it denotes the relative autonomy of the oriental Catholic Churches. This canonical term, pregnant with many juridical nuances, indicates the God-given mission of the Oriental Catholic Churches to keep up their patrimonial autonomous nature. And the autonomy of these churches is relative in the sense that it is under the supreme authority of the Roman Pontiff.
