Nestorius condemned at Ephesus

Nestorius objected to calling Mary 'God-bearer.' He feared the title confused Jesus' humanity and divinity. But to Cyril of Alexandria and the Council of Ephesus, his language sounded as though the human Jesus and the divine Son were too separate. Nestorius was removed as bishop. The point was not mainly Mary's status; it was the church's insistence that the baby she bore was truly the one Jesus Christ: God who had become human.
