How important is the transfiguration of Jesus Christ to the Christian faith? To summarize it, it is the cornerstone of the evidence behind the reality that Jesus was and is fully God and fully man. Without this eyewitness account of the unveiling of Christ's Divine glory, everything else that Jesus accomplished in His life would be diminished. The transfiguration stands at the heart of Messianic theology, supporting the claim that Jesus rose from the dead and lives ascended at the right hand of God in authority and power!
