O God of Truth O Lord of Might { O God of Truth O Lord of Might by St. Ambrose, 340-397 VETTER-Daniel Vetter NUNC SANCTE-Early plainsong, Mode VIII O God of Truth, O Lord of Might } O God of truth, O Lord of might, Who orderest time and change aright, And send'st the early morning ray, And light'st the glow of perfect day: Extinguish Thou each sinful fire, And banish every ill desire; And while Thou keep'st the body whole. Shed forth Thy peace upon the soul. O Father, that we ask be done, Through Jesus Christ, Thine only Son, Who, with the Holy Ghost and thee, Doth live and reign eternally. Amen.
