In ecclesiology of Eastern Orthodox Churches, there is a clear distinction between autonomy and autocephaly, since autocephalous churches have full self-governance and independence, while every autonomous church is subject to some autocephalous church, having a certain degree of internal self-governance. Since every autonomous church had its own historical path to ecclesiastical autonomy, there are significant differences between various autonomous churches in respect of their particular degrees of self-governance. For example, churches that are autonomous can have their highest-ranking bishops, such as an archbishop or metropolitan, appointed or confirmed by the patriarch of the mother church from which it was granted its autonomy, but generally they remain self-governing in many other respects.
