"Her [Mary's] motherhood extends beyond view.
In the will of the Son, she becomes at once mother and maid:
sheltering Him, but sheltered in Him,
forming Him, but formed by Him ...
When she pronounces the words: 'Be it done to me according to thy word', the Mother conceives the mystery from the Trinity, in order to give it to the Son.
The Son gives the word back to the Trinity by giving everything He has back to the Father in the Spirit. Then, after the Father has received it again, it is distributed to mankind by means of that extravagant expansioning —
the Eucharist and the Holy Spirit."
