Council of Seleucia-Ctesiphon: Under Mar Joseph, 554 AD (Paperback) (ISBN-13: 9798869185365)

This sixth ecumenical gathering of the Persian church at the Sassanian capital of Seleucia-Ctesiphon was related directly to the question of the authority of the Catholicos over other bishops in the Persian church, the acceptance of the Councils of Nicaea I, and Constantinople I, and the security of the bishops from illegitimate entanglements in the Persian state and pagan practices. While long forgotten by western scholars, it represents the first effort of the Church of the East to address Christological concerns raised during Roman councils in the empire.
