May is dedicated to Mary, Mother of God, Queen of Heaven, Protectress of America.
Mary attains a union with God that exceeds all the expectations of the human spirit. It even exceeds the expectations of all Israel, in particular the daughters of this Chosen People, who, on the basis of the promise, could hope that one of their number would one day become the mother of the Messiah. Who among them, however, could have imagined that the promised Messiah would be “the Son of the Most High”? On the basis of the Old Testament’s monotheistic faith such a thing was difficult to imagine. Only by the power of the Holy Spirit, who“overshadowed” her, was Mary able to accept what is “impossible with men, but not with God” (cf. Mk 10: 27).
…When Mary responds to the words of the heavenly messenger with her “fiat”, she who is “full of grace” feels the need to express her personal relationship to the gift that has been revealed to her, saying: “Behold, I am the handmaid of the Lord” (Lk 1:38). This statement should not be deprived of its profound meaning, nor should it be diminished by artificially removing it from the overall context of the event and from the full content of the truth revealed about God and man. In the expression “handmaid of the Lord”, one senses Mary’s complete awareness of being a creature of God. The word “handmaid”, near the end of the Annunciation dialogue, is inscribed throughout the whole history of the Mother and the Son. In fact, this Son, who is the true and consubstantial “Son of the Most High”, will often say of himself, especially at the culminating moment of his mission: “The Son of Man came not to be served but to serve” (Mk 10:45).
At all times Christ is aware of being “the servant of the Lord” according to the prophecy of Isaiah (cf.Is 42:1; 49:3, 6; 52:13) which includes the essential content of his messianic mission, namely, his awareness of being the Redeemer of the world. From the first moment of her divine motherhood, of her union with the Son whom “the Father sent into the world, that the world might be saved through him” (cf. Jn 3:17), Mary takes her place within Christ’s messianic service. It is precisely this service which constitutes the very foundation of that Kingdom in which “to serve … means to reign”.21 Christ, the “Servant of the Lord”, will show all people the royal dignity of service, the dignity which is joined in the closest possible way to the vocation of every person.
