"To destroy the ostentatious passion of boastfulness and stop people from trying to win greater honor than their teachers, Christ declared: The disciple is not above his teacher. Even if some should advance so far as to equal their teachers in holiness, they ought to remain within the limits set by them, and follow their example. Paul also taught this when he said: Be imitators of me, as I am of Christ. So then, if the Master does not judge, why are you judging? He came not to judge the world, but to take pity on it."
Cyril of Alexandria (ca. AD 444), On Luke 6: PG 72, 602-603
Cyril was the patriarch of Alexandria and a brilliant theologian who combatted the Arian and Nestorian heresies. He presided at the Council of Ephesus in 431 where Mary's title as Mother of God was solemnly recognized.
