Gospel: Luke 1.26-38
26Then, in the sixth month, the Angel Gabriel was sent by God, to a city of Galilee named Nazareth27to a virgin betrothed to a man whose name was Joseph, of the house of David; and the name of the virgin was Mary28And upon entering, the Angel said to her: "Hail, full of grace. The Lord is with you. Blessed are you among women.29And when she had heard this, she was disturbed by his words, and she considered what kind of greeting this might be30And the Angel said to her: "Do not be afraid, Mary, for you have found grace with God31Behold, you shall conceive in your womb, and you shall bear a son, and you shall call his name: JESUS32He will be great, and he will be called the Son of the Most High, and the Lord God will give him the throne of David his father. And he will reign in the house of Jacob for eternity33And his kingdom shall have no end.34Then Mary said to the Angel, "How shall this be done, since I do not know man?35And in response, the Angel said to her: "The Holy Spirit will pass over you, and the power of the Most High will overshadow you. And because of this also, the Holy One who will be born of you shall be called the Son of God36And behold, your cousin Elizabeth has herself also conceived a son, in her old age. And this is the sixth month for her who is called barren37For no word will be impossible with God.38Then Mary said: "Behold, I am the handmaid of the Lord. Let it be done to me according to your word." And the Angel departed from her
Sermon
The ancient prophecy of Isaiah speaks to us of King Ahaz, who, in a moment of national crisis, refused God's offer of a sign, claiming he would not tempt the Lord. Yet, God, in His divine wisdom, insists on providing one anyway: "Behold, a virgin will conceive, and she will give birth to a son, and his name will be called Immanuel." This powerful assurance, that "God is with us" and all human plans against His will are destined to fail, finds its profound fulfillment in the Gospel. There, the Angel Gabriel is sent to Mary, a virgin, announcing that she will conceive a son by the Holy Spirit, who will be called Jesus, the Son of the Most High, destined to reign eternally on David's throne. These two readings are deeply connected, for Luke reveals the very moment Isaiah's incredible prophecy began to unfold, showing us how God's promise of "Immanuel" would be perfectly embodied in the Incarnation of Jesus Christ through Mary.
The difference in response between King Ahaz and Mary offers us a poignant reflection. Ahaz, burdened by fear and self-reliance, chose to trust his own political schemes rather than God's direct intervention. Mary, though initially troubled and questioning how such a thing could be, ultimately surrendered to God's extraordinary and incomprehensible plan with profound humility and faith. We, too, often face moments in life where we are tempted to rely solely on our own understanding, our own strength, and human solutions, rather than opening our hearts fully to God's divine guidance. Mary's "Behold, I am the handmaid of the Lord; let it be done to me according to your word" reminds us that "no word will be impossible with God." Her faithful response becomes a model for our own lives, inviting us to embrace God's often unexpected will, knowing that He is truly Immanuel, always with us, ready to accomplish what seems impossible through our humble trust.
