O GOD, Who in Thy unspeakable providence dost vouchsafe to send Thy holy angels to be our guard: Grant that we, Thy humble servants, may always be defended by their aid and rejoice in their everlasting fellowship; through Jesus Christ, Thy Son, our Lord, who livest and reignest with the Father and the Holy Ghost, ever one God, world without end. Amen (Oremus, 1925, p.47).
