Some eparchies are organized into exarchates, or autonomous churches. These include the Belarusian, Latvian, Moldovan and Estonian Orthodox churches. The Chinese and Japanese Orthodox Churches were granted full autonomy by the Moscow Patriarchate, but this autonomy is not universally recognized. Smaller eparchies are usually governed by a single bishop. Larger eparchies, exarchates, and autonomous churches are governed by Metropolitan archbishops and sometimes have one or more bishops assigned to them. The highest level of authority in the Church is represented by the Patriarch of Moscow and All Russia, head of the Holy Synod of the Russian Orthodox Church. The Holy Synod is the governing body of the Church between the Bishops' Councils.
