O Clavis David, O Key of David | O Antiphon.
catholictv on Dec 19, 2016 Bishop Robert Reed chants the O Antiphon for December 20.
These Great "O Antiphons" at the Magnificat were first used by the Church in the 8th and 9th centuries.
They are said in order, based on various titles for the Christ and are scripturally-based short prayers for the 17th to the 23rd of December.
In these "O Antiphons" the Church expresses her deep longing for the coming of the Messiah.
Christ, harrower of hell
(See Isaiah 22:22; Revelation 3:7)
O Clavis David, et sceptrum domus Israël, qui aperis, et nemo claudit, claudis, et nemo aperuit: veni, et educ vinctum de domo carceris, sedentem in tenebris, et umbra mortis. O Key of David, and scepter of the house of Israel, you open, and no one shuts, you shut, and no one opens: come, and lead the prisoner from jail, seated in darkness and in the shadow of death.
