Read the account of Christ's holy Transfiguration (Metamorphosis in Greek) in Matthew ch. 17, Mark ch. 9, and Luke ch. 9. Appearing clothed in Light on Mt Tabor, the Savior fulfilled his promise to His disciples that "there are some standing here who shall not taste death, till they see the Son of man coming in His Kingdom" (Mt 16:28). Christ's Transfiguration is the image of the future state of the righteous, of which He spoke when He said "Then shall the righteous shine forth as the sun" (Mt 13:43). According to the Church's tradition, the Transfiguration occurred forty days before His Crucifixion; for this reason the Transfiguration is celebrated forty days before the Exaltation of the Cross.
