Ave Maria Meditations
God the Father communicated to His Son the divine nature. Mary gave Him a human nature, subject to pain and death, in which to redeem us. But Mary’s Son is the only begotten Son of the Father and in that consists the whole grandeur of her maternity…
The reason why Mary was given a fullness of grace from the first incident was that she might be an able to conceive the Man-God in holiness, by uttering her fiat with the utmost generosity on the day of the Annunciation in spite of the sufferings which she knew had been foretold of the Messiah; it was given her, too, that she might bring forth her child while remaining a virgin, that she might surround Him with the most motherly and most holy devotion. It was given her, finally, that she might unite herself to Him in the closest conformity, as only a most holy mother can, during His hidden life, His apostolic life, and His suffering life… that she might utter her second Fiat most heroically at the foot of the cross, with Him, by Him, and in Him…
There is this the most complete conformity between the will of Mary and her Son’s oblation which was, as it were, the soul of the Sacrifice of the Cross.
