Council of Markabta of the Arabs: Under Mar Dadisho 424 AD (Paperback) (ISBN-13: 9781087966748)

The council of Markabta was the third ecumenical council for the Church of the East, and one that would be held in response to the lack of central authority within the eastern church. Mar Dadisho is responding to various episcopal authorities within the realm who refuse to bow to his royally sanctioned authority. Moreover, this council marks that no Persian bishop can request assistance from bishops within the Roman Empire without the expressed consent of the patriarch in Seleucia-Ctesiphon.
