Elijah appeared to them with Moses and they were talking to Jesus. Mark 9:4
Law and prophecy are important elements of any established religion. One to set guidelines for moral behavior. The other to give us the current and active voice of God. The Jewish religion was firmly founded on these separate concepts.
After a few days from Peter’s correct definition and failed attempt of rebuking his mission, Jesus reveals the glorious supremacy of his divinity. The Christ is the embodiment of law and prophecy. He is the standard of righteousness and the current voice of holiness. True faith must never separate the two. A standard uninformed by a God who speaks at the present is stagnant and dying. A constantly moving voice without a standard is easily misled to death. Jesus is the foundation of Moses and the voice of Elijah. He is complete. The transfiguration confirms that he is purity, spirit, and the Son of God. His very being is too great for us to bear. His compassion allows us to draw near and follow him. So much for Peter’s attempted subversion. Alas for anyone who is ashamed of him.
If one’s walk with Jesus can be co-opted by human ideas or cast aside by worldly fear, the walk is false. No, true faith sees the fullness of the mysterious power of God. With reverent fear we are to embrace and follow Jesus as he is so much more than we can imagine. His synthesis of law and prophecy is the reason we carry the cross. His love and compassion gives us the strength to do so.
