Today, the Gospel carries the tone of a folk tale. Such accounts begin like this: "Once upon a time...", introducing the characters, the era, the place, and the theme. This story reaches its high point with the central plot; finally, there is the resolution.

Similarly, Saint Luke narrates the greatest story of all times in a popular and accessible manner. He presents not a tale conjured by imagination, but a reality woven by God Himself with human collaboration. The high point is: "You will conceive in your womb and bear a son, and you shall name him Jesus" (Lk 1:31).

This message tells us that Christmas is near. Mary will open the door for us with her cooperation in the Work of God. The humble girl of Nazareth listens in surprise to the angel's announcement. She was earnestly praying that God would soon send the Anointed One to save the world. Little did she imagine, in her modest understanding, that God had chosen her specifically to fulfill His plans.

Mary experiences tense, dramatic moments in her heart: she was and wanted to remain a virgin; now God proposes motherhood to her. Mary does not understand: "How can this be?" (Lk 1:34), she asks. The Angel explains that virginity and motherhood are not contradictory, but rather, through the power of the Holy Spirit, they are perfectly integrated. It's not that she now understands better. But explanation is enough for her, for she knows that the miracle will be God's work: "For nothing will be impossible with God" (Lk 1:37). Thus, she responds: "May it be done to me according to your word" (Lk 1:38). Let it be! Let it happen! Fiat! Yes. Total acceptance of God's Will, somewhat blindly, but without conditions.

In that very moment, "the Word became flesh and made his dwelling among us" (Jn 1:14). That folk tale becomes at the same time the most divine and most human reality. Pope Saint Paul VI wrote in 1974: "In Mary, we see the response that God gives to the mystery of man; and the question that man asks about God and his own life."
