Those of you who are fans of The Sound of Music will know that to begin at the beginning is a very good place to start. This morning’s Gospel does exactly that, by going back to the Annunciation of the Angel Gabriel to the Blessed Virgin Mary, the beginning of the story of Christmas. As we prepare to celebrate Christ’s birth this evening and tomorrow, it is only natural to return to the point of Our Lord’s Conception to help us to ponder the wonderful mystery which God accomplishes for our sake. 

At its heart, Christianity is a religion which declares that God becomes a human being, so that humanity can share in the life of God. This is what we believe as Christians, and why we proclaim this truth to the world. The greatest news in human history is a teenage pregnancy — something that is shocking and scandalous, is how God saves us. This is why St Paul can write to the Romans:

the revelation of the mystery that was kept secret for long ages but has now been disclosed and through the prophetic writings has been made known to all nations (Rom 16:25-26)

This is the proclamation of the Good News of Jesus Christ. It starts with an encounter in Nazareth. A young woman is engaged to be married and receives a visitor, who says:

“Greetings, O favoured one, the Lord is with you!” (Lk 1:28)

Mary is confused, she cannot understand what is going on. Biblical accounts of the interaction between God and humanity show us that ours is a God who takes risks. Mary could refuse, she could say no, and human history would be profoundly different. So the angel Gabriel says, ‘Paid ag ofni, Do not be afraid’. Mary does not need to be afraid because God is doing something wonderful. She will bear a son and call him Jesus, which means ‘God saves’. Jesus the Son of God will save God’s people from their sins, and will fulfil the promise made to David, which we heard in our first reading. 

Mary cannot understand how this will happen. The Holy Spirit, God active in the world, and the bond of love between God the Father and God the Son, will overshadow her. God will take flesh in her womb and be born as one of us. So Mary replies:

“Behold, I am the servant of the Lord; let it be to me according to your word.” (Lk 1:38)

Mary says ‘Yes’ to God. This is a ‘Yes’ which undoes the ‘No’ of Eve. It brings about the salvation of humanity, through the Life, Death, and Resurrection of her Son. Mary’s obedience to the will of God, ‘the obedience of faith’ (Rom 16:26), both trusts God to be at work, and makes it possible. We can be joyful because of Mary’s ‘yes’ to God. In her we have a pattern of obedience to the will of God which all Christians are to follow.

In the first reading this morning King David is worried. He says to Nathan the prophet:

“See now, I dwell in a house of cedar, but the ark of God dwells in a tent.” (2 Samuel 7:2)

Since the Exodus from Egypt, the Ark of the Covenant has resided in a  tabernacle, a tent, a temporary dwelling. This worries David, but God is not concerned whether he lives in a tent or a temple. It does not matter. God’s response is not to accept David’s offer, but instead to make David an amazing counter-offer:

Moreover, the Lord declares to you that the Lord will make you a house. When your days are fulfilled and you lie down with your fathers, I will raise up your offspring after you, who shall come from your body, and I will establish his kingdom…  I will be to him a father, and he shall be to me a son… And your house and your kingdom shall be made sure for ever before me. Your throne shall be established for ever.’” (2 Samuel 7:11-12, 14, 16)

God offers David a family, a Royal House. This is a promise which bears fruit with the coming of Jesus, born of the House of David, and the Son of God. Jesus’ mother Mary will be the living Ark of the New Covenant. This will be a covenant that is not made in stone, but rather in flesh; the flesh of the Son of God, who is born for us, and who dies for us. Mary’s womb will be the place where the Son of God will begin to dwell with us:

Therefore the Lord himself will give you a sign. Behold, the virgin shall conceive and bear a son, and shall call his name Immanuel. (Isa 7:14)

Immanuel in Hebrew means ‘God (is) with us’ and this is what we are preparing to celebrate at Christmas: God being among us. Let us then follow Mary’s example of obedience, listen to God, and trust Him to be at work in us. Let us welcome Jesus both in Bethlehem and here upon the altar, where God, who became flesh and blood in the womb of Mary, offers us His Body and Blood in the Eucharist, so that we might share His Life. Let us, like Mary, say, ‘Yes’ to God, welcome him into our hearts. Let us be beacons in the world, shining with God’s love. May all this Christmas come to believe and trust in God the Father, God the Son, and God the Holy Spirit. To whom be ascribed all glory, dominion, and power, now and forever. Amen.
