The Church has invoked the titles of Christ in the O Antiphons for at least 1,300 years. These seven ancient prayers have been prayed by over millions of Christians. The medieval monasteries used to ring their largest bell as the choirs of monks intoned Mary’s Magnificat and these Advent antiphons. They are invoking Christ in seven messianic titles. 
 
They are seven heart cries for Jesus to come anew in our life. Each one of them is preparing us to invite the Christ child more completely in this blessed season. 
 
Like a final crescendo, these O Antiphons are intoned during Evening Prayer on the seven days leading up to Christmas Eve, from December 17 to December 23. Each night they form luminous bookends around Our Lady’s Magnificat, like seven prayers she prayed during her week-long journey from Nazareth to Bethlehem. All seven are in the oracles of the Old Testament prophet Isaiah, who gives us many memorable images of the Messiah. They are rich meditations on the One who is to come. 
 
Although there are seven titles in the O Antiphons, only one has remained firmly in popular Christian culture, thanks to an Advent hymn: "O Come, O Come Emmanuel". This messianic title is the final of the O Antiphons. The seven titles prayed on each day are: 

• December 17: O Wisdom (Sapientia) - Isaiah 11:2-3  
  
• December 18: O Lord of Might (Adonai) - Isaiah 11:4-5 
  
• December 19: O Root of Jesse (Radix Jesse) - Isaiah 11:1; 11:10 
  
• December 20: O Key of David (Clavis David) - Isaiah 22:22 
  
• December 21: O Radiant Dawn (Oriens) - Isaiah 9:2 
  
• December 22: O King of the Nations (Rex Gentium) - Isaiah 2:4; 9:6; 11:10-12 
  
• December 23: O Emmanuel (Emmanuel) - Isaiah 7:14

"Again his voice roars, his majestic voice thunders ..." - Job 37:4 

The cacophony of noise drums in my head.  The medical term for it is "tinnitus"; I simply call it "aggravating".  While some refer to it as "ringing" or "buzzing" in the ears, I wish it were only a "ring" or a "buzz". 

I have read of some  people who patiently pray for the noise to stop so that they can sit silently and listen for the voice of God.  There has to be a different approach. 

Maybe this is God's way of getting my attention.  Perhaps He is speaking, loud and clear; I just refuse to listen to it.  I see it as "aggravating noise"; He sees it as a still voice speaking thunderously to me. 

"Speak, Lord, for your servant is listening." - 1 Samuel 3:9
