CWN - Mar Dinkha IV, who became head of the Assyrian Church of the East in 1976, died in the United States on March 26 at the age of 79, according to the Assyrian International News Agency.
The church ceased to be in full communion with the Holy See following the Ecumenical Council of Ephesus (431). In the sixteenth century, some bishops from the Assyrian Church of the East sought full communion with the Holy See, giving rise to the Chaldean Catholic Church.
