"Nestorius: If anyone says that the Emmanuel is true God, and not rather God with us, that is, that he has united himself to a like nature with ours, which he assumed from the Virgin Mary, and dwelt in it; and if anyone calls Mary the mother of God the Word, and not rather mother of him who is Emmanuel; and if he maintains that God the Word has changed himself into the flesh, which he only assumed in order to make his Godhead visible, and to be found in form as a man, let him be anathema."
~ First of "Twelve Anathemas by St. Cyril Against Nestorius," Council of Ephesus (431).
Artwork: Virgin salus populi romani, the oldest Marian icon in Rome, probably Early Christian (rather than Medieval); Borghese or Pauline Chapel of the Santa Maria Maggiore Basilica in Rome.
