The Word of God is not a literary expression, but is the indication of an event, it is always a fact: the Word of God is Christ. His word starts from the promise of an event. The figure of the Virgin is completely filled with memory, the word of her people, stretching completely toward the meaning of these events (the Angel’s announcement, Elizabeth’s greeting). This is why Elizabeth used the highest form of address: ‘Blessed is she who believed in the fulfillment of the Word of the Lord.’
