The Transfiguration of Christ is recorded in the first three Gospels (Matthew 17:1-9  Mark 9: 2-9  Luke 9: 28 -36) The fourth does not contain an account of the event  but its author  being one of the three witnesses  is probably referring specifically to it when he says: And the Word was made flesh  and dwelt among us  And we beheld His glory  the glory as of the only begotten of the Father  full of grace and truth (1:14)
