From Office of Readings:
Jesus goes before us to show us the way, both up the mountain and into heaven, and --I speak boldly--it is for us now to follow him with all speed, yearning for the heavenly vision that will give us a share in his radiance, renew our spiritual nature and transform us into his own likeness, making us for ever sharers in his Godhead and raising us to heights as yet undreamed of.Let us run with confidence and joy to enter into the cloud like Moses and Elijah, or like James and John. Let us be caught up like Peter to behold the divine vision and to be transfigured by that glorious transfiguration. Let us retire from the world, stand aloof from the earth, rise above the body, detach ourselves from creatures and turn to the Creator. . .
