In Eastern Orthodoxy, autonomy designates a type of limited self-government of a church (group) toward its mother church. An autonomous church is self-governing in some aspects, which differentiates it from a non-autonomous church. The aspects on which the autonomous church is self-governing depends on the decision of the mother church. A church that is autonomous has its highest-ranking bishop, such as an archbishop or metropolitan, approved by the primate of the mother church.
