In message 41 on another thread Mary introduces the canons of the Council of Carthage of 418 and describes them as the "deal breaker" on a matter concerning original sin and Baptism. She mentions that the canons of this Council of Carthage were ratified by the Ecumenical Councils of Ephesus and Nicea II.http://www.orthodoxchristianity.net/forum/index.php/topic,27401.msg496563.html#msg496563
It is noteworthy that Canon 17 of this Council rejects appeals to Rome and excommunicates any who do so.
Can. 17 “If priests, deacons, and inferior clerics complain of a sentence of their own bishop, they shall, with the
consent of their bishop, have recourse to the neighboring bishops, who shall settle the dispute. If they desire to make
a further appeal, it must only be to their primates or to African Councils. But whoever appeals to a court on the other
side of the sea (Rome), may not again be received into communion by any one in Africa.”
Two Ecumenical Councils and two Popes
rejected appeals to Rome at the highest level of the Church:
1. The Ecumenical Council of Ephesus which was ratified by Pope Saint Celestine I
2. The Ecumenical Council of Nicea II which was ratified by Pope Hadrian.
