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."
