United with her in one sacrifice

Madonna and Child

Giovanni Bellini

18. God the Son came into her virginal womb as a new Adam into his earthly paradise, to take his delight there and produce hidden wonders of grace. 

God-made-man found freedom in imprisoning himself in her womb. He displayed power in allowing himself to be borne by this young maiden. He found his glory and that of his Father in hiding his splendours from all creatures here below and revealing them only to Mary. He glorified his independence and his majesty in depending upon this lovable virgin in his conception, his birth, his presentation in the temple, and in the thirty years of his hidden life. Even at his death she had to be present so that he might be united with her in one sacrifice and be immolated with her consent to the eternal Father, just as formerly Isaac was offered in sacrifice by Abraham when he accepted the will of God. It was Mary who nursed him, fed him, cared for him, reared him, and sacrificed him for us. 

The Holy Spirit could not leave such wonderful and inconceivable dependence of God unmentioned in the Gospel, though he concealed almost all the wonderful things that Wisdom Incarnate did during his hidden life in order to bring home to us its infinite value and glory. Jesus gave more glory to God his Father by submitting to his Mother for thirty years than he would have given him had he converted the whole world by working the greatest miracles. How highly then do we glorify God when to please him we submit ourselves to Mary, taking Jesus as our sole model.
