John Wesley on Matthew 17:2

And was transfigured - Or transformed. The indwelling Deity darted out its rays through the veil of the flesh; and that with such transcendent splendour, that he no longer bore the form of a servant. His face shone with Divine majesty, like the sun in its strength; and all his body was so irradiated by it, that his clothes could not conceal its glory, but became white and glittering as the very light, with which he covered himself as with a garment.
