Wouldn't it be wonderful to see your best friend transformed, or turned into his or her glorified self, right before your eyes? That's the kind of experience Peter, James, and John have in today's gospel. While they are up on a mountain with Jesus, they have a splendid vision of him in his glorified body. They see him talking with Moses and Elijah, two long-dead figures from the Old Testament. Moses represents the Law, while Elijah represents the prophets. In Jesus, both find the fulfillment of God's plan of salvation.
