Fourth "O" Antiphon (for Dec 20) paraphrased from an article by Michael P. Mernagh in a church bulletin:
"O Key of David, And scepter of the house of Israel,
Who opens, and no one closes,
Who closes, and no one opens:
Come, and lead forth the house of bondage.
The captive sitting in darkness and the shadow of death." -- Isa 22, Rev 3:7
David's key and scepter were nothing in comparison to
Your key and scepter, our Messiah.
You are the key of David, Jesus,
who can open the hearts and minds of those
whose lives are locked in fear, disease and sin.
Open our own hearts,
Empty us of all that keeps us from being who we are called to be,
Fill us with the grace of God that transforms our lives,
Lead us to full personhood.
