Composed by Basil The Great (330-379 A.D.)
from the Orthodox Prayer Book
"O Lord Almighty, God of hosts and of all flesh, Who dwellest on high and lookest down on things that are lowly, Who searchest our hearts and innermost being, and clearly foreknowest the secrets of men; O unoriginate and everlasting Light, in Whom is no variableness, neither shadow of turning; Do Thou, O Immortal King, receive our supplications which we, daring because of the multitude of Thy compassions, offer Thee at the present time from defiled lips; and forgive us our sins, in deed, word, and thought, whether committed by us knowingly or in ignorance, and cleanse us from every defilement of flesh and spirit. And grant us to pass through the night of the whole present life with watchful heart and sober thought, ever expecting the coming of the bright and appointed day of Thine Only-begotten Son, our Lord and God and Saviour, Jesus Christ, whereon the Judge of all shall come with glory to reward each according to his deeds. May we not be found fallen and idle, but watching, and upright in activity, ready to accompany Him into the joy and divine palace of His glory, where there is the ceaseless sound of those that keep festival, and the unspeakable delight of those that behold the ineffable beauty of Thy countenance. For Thou art the true Light that enlightenest and sanctifiest all, and all creation doth hymn Thee unto ages of ages.
