“Orthodoxy” means “right opinion” or “right belief” (also “right glorification”, as in the Slavonic translation). Within the Christian context, the term came to be associated with certain sections of Eastern Christendom: the Chalcedonian (or Eastern Orthodox) and non-Chalcedonian (or Oriental Orthodox) churches. Eastern Christians are not united within one communion. The main divisions appeared in the 5th century.
