fourth Sunday of Advent

"We beseech thee, Almighty God,
       to purify our consciences by thy daily visitation,
that when thy Son our Lord 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 forever. Amen."

                               -  Book of Common Prayer, 1789
