Belarusian Autocephalous Orthodox Church

The Belarusian Autocephalous Orthodox Church (Belarusian: Беларуская аўтакефальная праваслаўная царква, Bielaruskaja aŭtakiefaĺnaja pravaslaŭnaja carkva BAPC), sometimes abbreviated as B.A.O. Church or BAOC, is an independent Eastern Orthodox church, unrecognized by the mainstream Eastern Orthodox communion. Due to persecution against the Church in the Republic of Belarus, it exists either underground or abroad.
