Origen

“ But if you wish to see the transfiguration of Jesus before those who went up into the lofty mountain apart long with Him, behold with me the Jesus in the Gospels, as more simply apprehended, and as one might say, known “according to the flesh,” by those who do not go up, through works and words which are uplifting, to the lofty mountain of wisdom, but known no longer after the flesh, but known in His divinity by means of all the Gospels, and beholden in the form of God according to their knowledge ”

“ But when He is transfigured, His face also shines as the sun, that He may be manifested to the children of light, who have put off the works of darkness, and put on the armour of light, [2] and are no longer the children of darkness or night, but have become the sons of day, and walk honestly as in the day ”
