[[Jesus Christ|Jesus]] had gone with his disciples [[Apostle Peter|Peter]], [[Apostle James (son of Zebedee)|James]], and [[Apostle John|John]] to [[Mount Tabor]]. Christ's appearance was changed while they watched into a glorious radiant figure. There appeared [[Elijah]] and [[Moses]], speaking with Jesus. The disciples were amazed and terribly afraid.
This event shows forth the divinity of Christ, so that the disciples would understand after his Ascension that He was truly the radiant splendor of the [[Father]], and that his Passion was voluntary ([[Gospel of Mark|Mark]] 9:2-9). It also shows the possibility of our own [[theosis]].
This event was the subject of some debates between [[Gregory Palamas]] and [[Barlaam of Calabria]]. Barlaam believed that the light shining from Jesus was created light, while Gregory maintained the disciples were given grace to perceive the uncreated light of God. This supported Gregory's larger argument that although we cannot know God in His ''essence'', we can know Him in his ''energies'', as He reveals Himself.
Accounts of the Transfiguration are found in the [[Bible]]: [[Gospel of Matthew|Matthew]] 17:1-8, [[Gospel of Mark|Mark]] 9:2-9,
and [[Gospel of Luke|Luke]] 9:28-36.

In Greece the harvest season traditionally began on the Transfiguration.
Grapes, in particular, were not eaten before August 6. In some parishes, the first grapes would be brought to church for a blessing and distributed to parishioners.
