O Key of David, opening gates of God's eternal Kingdom:
come and free the prisoners of darkness!
Mother Stuart: the key in so many ways.
a) Because in Him "dwells all the fullness of the Godhead corporeally," and He opens its treasures to us.
b) The key to all our questions. For those as to God's dealing with us, the answer to all : Verbum caro factum est. For those as to our relations with God, "Jesus Christ and Him crucified: in the Blessed Sacrament, the answer is Domine quid est?
c) Key of authority "I will lay the key of the house of David on His shoulders - He shall open and none shall shut."
His power "of the keys" gives us absolute security. "I have set before thee an open door and none shall shut it, and again we are shut up in safety with Him in such security that none can open. Quis nos separabit?... Enter into the chamber, shut the door.
