Apostolic Catholic Assyrian Church of the East, North American Dioceses

The Holy Apostolic Catholic Assyrian Church of the East is the ancient Christian church that developed within the Persian Empire from the day of Pentecost. The Apostolic traditions testify that the Church of the East was established by Sts. Peter, Thomas, Thaddaeus and Bartholomew from among the Twelve and by the labors of Mar Mari and Aggai of the Seventy. The Church grew and developed carrying the Christian gospel into the whole of Asia and islands of the Pacific. Prior to the Great Persecution at the hands of Tamer'leng the Mongol, it is said to have been the largest Christian church in the world.
The doctrinal identity of the church is that of the Apostles. The church stresses two natures and two Qnume in the One person, Perfect God-Perfect man. The church gives witness to the original Nicene Creed, the Ecumenical Councils of Nicea and Constantinople and the church fathers of that era. Since God is revealed as Trinity, the appellation "Mother of God" is rejected for the "Ever Virgin Blessed Mary Mother of Christ," we declare that she is Mother of Emmanuel, God with us!
The church has maintained a line of Catholicos Patriarchs from the time of the Holy Apostles until this present time. Today the present occupant of the Apostolic Throne is His Holiness Mar Dinkha IV, 120th successor to the See of Selucia Ctestiphon.
