Notice the contrast and the choice of words. Elizabeth is the first to hear Mary’s voice, but John is the first to be aware of grace.
She hears with the ears of the body, but he leaps for joy at the meaning of the mystery.
She is aware of Mary’s presence, but he is aware of the Lord’s: a woman aware of a woman’s presence, the forerunner aware of the pledge of our salvation.
The women speak of the grace they have received while the children are active in secret, unfolding the mystery of love with the help of their mothers, who prophesy by the spirit of their sons.
The child leaps I the womb; the mother is filled with the Holy Spirit, but not before her son.
Once the son has been filled with the Holy Spirit, he fills his mother with the same Spirit. John leaps for joy, and the spirit of Mary rejoices in her turn.
When John leaps for joy Elizabeth is filled with the Holy Spirit, but we know that though Mary’s spirit rejoices, she does not need to be filled with the Holy Spirit.
Her son, who is beyond our understanding, is active in his mother in a way beyond our understanding.
Elizabeth is filled with the Holly Spirit after conceiving John, while Mary is filled with the Holy Spirit before conceiving the Lord.
Elizabeth says: Blessed are you because you have believed.
You also are blessed because you have heard and believed. A soul that believes both conceives and brings forth the Word of God and acknowledges his works.
Let Mary’s soul be in each of you to proclaim the greatness of the Lord. Let her spirit be in each to rejoice in the Lord.
Christ has only one mother in the flesh, but we all bring forth Christ in faith. Every soul receives the Word of God if only it keeps chaste, remaining pure and free from sin, its modesty undefiled.
The soul that succeeds in this proclaims the greatness of the Lord, just as Mary’s soul magnified the Lord and her spirit rejoiced in God her Savior.
In another place we read: Magnify the Lord with me. The Lord is magnified, not because the human voice can add anything to God but because he is magnified within us.
Christ is the image of God, and if the soul does what is right and holy, it magnifies that image of God, in whose likeness it was created and, in magnifying the image of God, the soul has a share in its greatness and is exalted.
