Second Council of Constantinople — Anathemas 1.6

Chapter 1 — Anathemas I–VII

Section 6. VI. If anyone says that the holy, glorious, and ever-virgin Mary is the mother of God in name only and not in truth, or by analogy only, meaning that merely a man was born and not God the Word incarnate, and asserting that the man was referred to the Word because the Word was with him when born — and if anyone slanders the holy Council of Chalcedon as calling the Virgin Mother of God in the impious sense of Theodore — or if anyone calls her mother of a man or mother of Christ, meaning that Christ is not God: let him be anathema.
