O GOD, who on the mount didst reveal to chosen witnesses thine only-begotten Son wonderfully transfigured, in raiment white and glistering; Mercifully grant that we, being delivered from the disquietude of this world, may be permitted to behold the King in his beauty, who with thee, O Father, and thee, O Holy Ghost, liveth and reigneth, one God, world without end. Amen.
(H/T Jesse Nigro)
