Then Mary said, “Here am I, the servant of the Lord; let it be with me according to your word.” Then the angel departed from her. (Luke 1.38)
The feast of the Annunciation is important not simply as a historical commemoration of something that happened long ago, but more of what it reveals about God: that God chose to create a world in which, to realize the dream he had for creation, human freedom had to be included. God never “decrees” in a way that violates human freedom. Rather, God offers and looks for the free acceptance of the creature. Thus God did not simply plant Jesus on earth arbitrarily. God required the free assent of the creature. This is what Mary’s “Fiat” really is: an utterance that frees the Divine Will to realize the ultimate plan for all creation.
