Mopsuestia. They have been sometimes, erroneously, called Nestorian. This appellation is rejected by the Catholic Church. Dialogue began with a meeting of the Assyrian Patriarch (Catholicos) Mar Dinkha IV and Pope John Paul II in 1984, and the patriarch's participation in the first Assisi Day of Prayer for Peace in 1986. Nearly a decade of dialogue proved sufficient to resolve the disagreements over terminology in Christology, leading to the Common Christological Declaration Between the Catholic Church and the Assyrian Church of the East, signed by Pope John Paul II of the Catholic Church and Mar Dinkha IV of the Assyrian Church of the East in 1994. The Common Declaration recalls that the Assyrian Church of the East prays to the Virgin Mary as "the Mother of Christ our God and Saviour", and the Catholic tradition addresses the Virgin Mary as "the Mother of God" and also as "the Mother of Christ", fuller expressions by which each Church clearly acknowledges both the divinity and the humanity of Mary's son. The co-signers of the Common Declaration could thus state: "We both recognize the legitimacy and rightness of these expressions of the same faith and we both respect the preference of each Church in her liturgical life and piety." Over the next six years, annual meetings of the dialogue came to a common understanding of sacraments, published in 2000 as the "Common Statement on Sacramental Life". It was hoped that this too would be raised to the level of a Joint or Common Declaration, while the dialogue moved on to practical ecclesiological, pastoral, and administrative questions for full communion. However, in 2004, on the eve of a formal common declaration, the Assyrian patriarch and bishops decided to suspend the dialogue, realizing that "all obstacles to restoring full communion with the Catholic Church had been proven to no longer exist". The following year the Assyrian synod suspended their chief ecumenist of twenty years, Mar Bawai Soro, who had led the dialogue with Rome. In 2008, Mar Bawai, along with six priests, thirty deacons, and about a thousand faithful, broke communion with the Assyrian Church and entered into full communion as part of the Chaldean Catholic Church. The personal tensions from these events further delayed the continuation of reunion talks. In March 2015, Mar Dinkha IV died. In September 2015, a new Catholicos-Patriarch was elected, Gewargis III.
