How do we know that the Transfiguration is true?

The reliability of the Transfiguration account is strengthened by its multiple attestations within Scripture. The event is recorded in three Gospels—Matthew, Mark, and Luke—providing a corroborative testimony from different perspectives. Peter, who was present, later reaffirmed this witness in his epistle, asserting that they were not following cleverly devised fables but were eyewitnesses of Christ's majesty. The presence of Moses and Elijah further corroborates this truth by linking the event to the fulfillment of Old Testament prophecy, demonstrating the continuity and divine authority of Jesus Christ in God's redemptive plan.
