As we come to the end of Advent, at Evening Prayer we use special antiphons (verses before and after) with the Magnificat (The Song of Mary, Luke 1:46-55). The texts are of unknown origin and date at least from the ninth century and are likely far older and provide an excellent source for reflection in the days before Christmas.
Each antiphon begins with the letter "O" and a name or attribute of God from the Hebrew Scriptures:
O Wisdom of our God Most High,
guiding creation with power and love:
come to teach us the path of knowledge!
O Leader of the House of Israel,
giver of the Law to Moses on Sinai:
come to rescue us with your mighty power!
O Root of Jesse’s stem,
sign of God’s love for all his people:
come to save us without delay!
O Key of David,
opening the gates of God’s eternal Kingdom:
come and free the prisoners of darkness!
O Radiant Dawn,
splendor of eternal light, sun of justice:
come and shine on those who dwell in darkness and in the shadow of death.
O King of all nations and keystone of the Church:
come and save man, whom you formed from the dust!
O Emmanuel, our King and Giver of Law:
come to save us, Lord our God!
