Second Council of Constantinople — Anathemas 2.14

Chapter 2 — Anathemas VIII–XIV

Section 14. XIV. If anyone shall defend the letter which Ibas is said to have written to Maris the Persian, which denies that the Word of God incarnate of the Holy God-bearer and ever-virgin Mary became man, but says that a mere man was born of her whom it calls a Temple, as if the Word of God were one person and the man another; which condemns Saint Cyril as a heretic, when he gives the true doctrine of Christians; and accuses Saint Cyril of holding the opinions of the impious Apollinaris; which rebukes the first Synod of Ephesus as having deposed Nestorius without examination; and calls the twelve Chapters of Saint Cyril impious and contrary to the right faith; and defends Theodore and Nestorius and their impious teachings and writings: if anyone, I say, shall defend the said letter and shall not anathematize it and all who defend and justify it, or who say that it or any part of it is correct, and those who write and have written in favour of it or of the impieties contained in it, and who dare to justify it or the impieties contained in it in the name of the Holy Fathers or of the Holy Synod of Chalcedon, and shall persist therein until the end: let him be anathema.
