Mary heard God’s word and kept it, and so she is blessed. She kept God’s truth in her mind, a nobler thing than carrying his body in her womb. The truth and the body were both Christ: he was kept in Mary’s mind insofar as he is truth, he was carried in her womb insofar as he is man; but what is kept in the mind is of a higher order than what is carried in the womb. (Saint Augustine, +430)
