How do we know the Transfiguration is true?

The truth of the Transfiguration is established through the synoptic Gospels, where Matthew, Mark, and Luke all provide detailed accounts of this event (Matthew 17:1-9, Mark 9:2-8, Luke 9:28-36). The consistent nature of these narratives across different writers underscores its significance and authenticity. In addition, the presence of Peter, James, and John as eyewitnesses offers credible testimony to the events they experienced. Their reaction and the authoritative voice from the cloud that identifies Jesus as God's beloved Son serve to reinforce the miraculous nature of this event. Such corroboration serves to strengthen the believer’s faith in the unfolding of God's redemptive plan through Christ.
