St Cyril of Alexandria

Cyril of Alexandria is one of the great doctrinal bishops of the ancient Church, and his life cannot be made gentle by leaving out the conflict. He inherited a difficult see, carried real force of temperament into office, and then found himself at the center of the Nestorian controversy, where the Church's language about Christ and about the Blessed Virgin was under intense strain. The issue was not academic. Was the one born of Mary truly God made man, or had the mystery of the Incarnation been divided into something less? Cyril fought with energy, persistence, and at times undeniable harshness to keep the Church's confession clear.

The long struggle led through appeals to Rome, confrontation with Nestorius, and the Council of Ephesus, where Mary's title as Mother of God was defended precisely because the child she bore is one divine person. Cyril is not attractive because he is mild. He is important because he was battling for something central, and because the doctrinal clarity later generations received came through battles like his. His faults remain visible, but so does his greatness as a theologian-bishop who refused to let the mystery of Christ be blurred.
