The MOST Theological Collection: Outline of Christology
"IX. Theotokos"
Mrs. Smith cooperates merely in the production of the body of her baby John Smith, not at all in producing his soul, which God alone creates. Yet we call her the mother of John Smith, not the mother of the body of John Smith. Similarly, the child of Mary is God. So she is Theotokos, Mother of God. (The history of the controversies in the Patristic age on this and other Christological doctrines will be taken up later.)
