The Feast of the Transfiguration of Our Lord, God and Savior Jesus Christ is celebrated each year on August 6. The feast commemorates the transfiguration or metamorphosis of Christ on Mount Tabor, when our Lord appeared in His divine glory before the Apostles Peter, James, and John.
The event of the Transfiguration is recorded in three of the four Gospels:Matthew 17:1-9, Mark 9:2-8, and Luke 9:28-36. Jesus took the Apostles Peter, James, and John with Him up upon a mountain, and while they were on the mountain Jesus was transfigured. His face shone like the sun, and His garments became glistening white.
Moses and Elijah appeared with Christ, talking to Him. Peter declared how good it was for them to be there and expressed the desire to build three booths for Moses, Elijah, and Christ. This reference to the booths could imply that this occurred during the time of the Feast of Tabernacles when the Jews would be camping out in the fields for the grape harvest; for this Feast had acquired other associations in the course of its history, including the memory of the wanderings in the wilderness recorded in the Old Testament book of Exodus.
