As you can see from the sculpture, Cyril brooked no compromise with Nestorius or his views on the nature of Jesus Christ. Although the sculpture suggests it, Cyril did not actually kill Nestorius but the Council of Ephesus affirmed the truth that Mary is properly called the Mother of God and condemned Nestorianism. The Nestorians disputed that Mary, a human, could properly be called the Mother of God, only Mother of Jesus' humanity since it was not inextricably linked to his divinity. In fact, the Council of Chalcedon would later declare that the divinity and humanity of Christ are united indivisibly.
