His writings include the homily given in Ephesus and several other sermons. Some of his alleged homilies are in dispute as to his authorship. In several writings, Cyril focuses on the love of Jesus to his mother. On the Cross, he overcomes his pain and thinks of his mother. At the wedding in Cana, he bows to her wishes. Cyril created the basis for all other mariological developments through his teaching of the blessed Virgin Mary, as the "Mother of God." The conflict with Nestorius was mainly over this issue, and it has often been misunderstood. "he debate was not so much about Mary as about Jesus. The question was not what honors were due to Mary, but how one was to speak of the birth of Jesus."
