In this antiphon the coming Messiah is given the title of Key of David. A key is used to open and close, to lock and unlock. How are we to use this key? The answer is found in this morning’s Gospel of the Annunciation.
As I have been sitting with this Gospel what stands out for me are all the emotions: the joy, fear and uncertainty, but above all, the excitement of the Angel Gabriel.

In a few minutes we will sing the second great ‘O’ antiphon in Latin, just before the Magnificat. The translation in our breviaries reads:

O Adonai, and leader of Israel, you appeared to Moses in a burning bush, and gave him the law on Sinai. O come and save us with your mighty power.

The first Advent ‘O Antiphon’, ‘O Wisdom’, is woven from the book of Wisdom of Sirach (24:3) and the book of Wisdom (8:1). The wisdom that has come from the mouth of the Most High is His Son, the eternal Word of God. As St. John of the Cross say, in this one Word that the Father spoke, there is hidden everything he had to say - all Divine Wisdom. According to it, he created the world, according to it, he rules it and saved it.

The Mass readings for this first Sunday of Advent provide us with a wake-up call: St Paul tells us “you must wake up now” and in the Gospel Jesus tells us to “stay awake!” while the Prophet Isaias invites us to “walk in the light of the Lord.” So as we begin a new Church year we are invited to come into the light – to remove the blinds from the windows of our hearts and to let the light shine in – remembering that the true Light is Jesus Himself. He is the True Light shining on us and who desires to penetrate and posses our inmost being.

Immanuel, a name which means God is with us.
In Jesus we see our God made visible.

This is what Christ said on coming into the world. “You, who wanted no sacrifice or oblation, prepared a body for me. I am coming to do your will.” And this will was for us, you and me, to be made Holy by the offering of that body once and for all, for our salvation

O Rising Sun. You are the splendour of Eternal Light and the Sun of Justice.
O come and enlighten those who sit in darkness, those who dwell in the shadows of death.

At this time of year, and today as the shortest day of the year, it is wonderful how the Church puts on our lips this antiphon where we call on the Light of Christ to come and enlighten our darkness. My prayer during this Advent season is asking for the grace to acknowledge the times when we prefer darkness before true light, as the intercessions for Week One of Advent put it.

The fourth of the Advent antiphons evokes the coming of Jesus with a title referring to the great King David and the prophecy of Isaiah, who wrote:
‘I will put the key of the house of David on his shoulder; when it opens, no one will close; when it closes, no one will open it‘ (Is.22, 22)

How to understand this prophecy?

“O Adonai and leader of Israel,
you appeared to Moses in a burning bush
and you gave him the Law on Sinai.
O come and save us with your mighty power.”

In this antiphon we call on God by the name Adonai. The dictionary says that this word comes from the Cannanite and Hebrew word adon, which means - LORD. When God appeared to Moses, he called himself: I AM WHO I AM. (Ex 3:14). Out of reverence the Jews did not utter his name but substituted Adonai.
