O Clavis David — “O Key of David”

The Fourth Sunday Of Advent

We beseech thee, Almighty God, to purify our consciences by thy daily visitation, that when thy Son Jesus Christ cometh he may find in us a mansion prepared for himself; through the same Jesus Christ our Lord, who liveth and reigneth with thee, in the unity of the Holy Spirit, one God, now and for ever. Amen.
