The Church's relations with its fellow Assyrians in the Assyrian Church of the East have improved in recent years. In 1994 Pope John Paul II and Patriarch Dinkha IV of the Assyrian Church of the East signed a "Common Christological Declaration". On the 20 July 2001, the Holy See issued a document, in agreement with the Assyrian Church of the East, named "Guidelines for admission to the Eucharist between the Chaldean Church and the Assyrian Church of the East", which confirmed also the validity of the Anaphora of Addai and Mari.
