(Emperor Justitian) has pointed out, as you have learned from the contents of his letter, that disputes have arisen over the following three questions: Can one say that Christ our God is "one of the Trinity", that is one holy person among the three persons of the Holy Trinity? Did Christ our God who in His divinity is impassible suffer in the flesh? Must Mary, the ever Virgin Mother of our Lord and God Jesus Christ, be called truly and properly Mother of God and Mother of God the Word incarnate from her?...
Christ is one of the Holy Trinity, that is one holy person or subsistence (subsistentia)--one hypostasis as the Greeks say--one among the three persons of the Holy Trinity.
(There follow among other quotations: Gen. 3.22; 1 Cor. 8.6; the Nicene Symbol).
The fact that God did truly suffer in the flesh we confirm likewise by the following witnesses (Deut. 28.66; Jn 14.6; Mal. 3.8; Acts 3.15; 20.28; 1 Cor. 2.8; Cyril of Alexandria, Anathematism 12; Leo I, Tome to Falvian, etc.).
