Jesus Christ took three of His disciples, Peter, James, and John, up on a mountain, where Moses and Elijah appeared and Jesus was transfigured before them; His face and clothes becoming white and shining as light, and a voice came out of heaven saying, “This is My beloved Son, in whom I am well pleased; listen to Him” (Mk 9:2-13; Mt 17:1-13; Lk 9:28-36).
On August 6th, the Church celebrates the Transfiguration of the Lord as a major feast day. The Transfiguration is a theophany — a manifestation of God — showing Christ’s divinity through the display of His uncreated, divine light. This dates back to before 1000 A.D. in the Eastern Catholic Church.
It was not widely accepted in the Western Church until 1457 when Callistus III instituted it in remembrance of the victory gained over the Turks at Belgrade on July 22, 1456. News of the declaration reached Rome on August 6th, and the date of the Feast of the Transfiguration was set as a thanks offering.
