O God, whose hand hath spread the sky, and all its shining hosts on high, and painting it with fiery light, made it so beauteous and so bright: Thou, when the fourth day was begun, didst frame the circle of the sun, and set the moon for ordered change, and planets for their wider range: To night and day, by certain line, their varying bounds Thou didst assign; and gav'st a signal, known and meet, for months begun and months complete. Enlighten Thou the hearts of men: polluted souls make pure again: unloose the bands of guilt within: remove the burden of our sin. Grant this, O Father, ever One with Christ, Thy sole-begotten Son, Whom, with the Spirit we adore, one God, both now and evermore.
