The Consecration of a Grave

From the Book of Divine Worship - The Burial of the Dead - Rite Two.

If the grave is in a place that has not previously been set apart for Christian burial, the Priest may use the following prayer, either before the service of Committal or at some other convenient time.

O God, whose blessed Son was laid in a sepulcher in the garden: Bless, we pray, this grave, and grant that he whose body is (is to be) buried here may dwell with Christ in paradise, and may come to your heavenly kingdom; through your Son Jesus Christ our Lord. Amen.
