In celebrating the Incarnation of the Son, therefore, we cannot fail to honour his Mother. The Angel's proclamation was addressed to her; she accepted it, and when she responded from the depths of her heart: "Here I am... let it be done to me according to your word" (Lk 1: 38), at that moment the eternal Word began to exist as a human being in time. From generation to generation, the wonder evoked by this ineffable mystery never ceases. St Augustine imagines a dialogue between himself and the Angel of the Annunciation, in which he asks: "Tell me, O Angel, why did this happen in Mary?". The answer, says the Messenger, is contained in the very words of the greeting: "Hail, full of grace" (cf. Sermo 291: 6).
In fact, the Angel, "appearing to her", does not call her by her earthly name, Mary, but by her divine name, as she has always been seen and characterized by God: "Full of grace - gratia plena", which in the original Greek is 6,P"D4JTµXv0, "full of grace", and the grace is none other than the love of God; thus, in the end, we can translate this word: "beloved" of God (cf. Lk 1: 28). Origen observes that no such title had ever been given to a human being, and that it is unparalleled in all of Sacred Scripture (cf. In Lucam 6: 7).

As we continue to move through the Lenten season, let us look at our own hearts; we who are infinitely loved by God. "Dear Lord, whatever is your will for my life, let it be done unto ME, according to your Word."
