Jesus doesn't want his friends groveling on the ground in terror, or keeping him in a distant box in a shrouded tent... He doesn't want things done the old way. Jesus wants them to get up. To be fearless. And to be with him. In The Transfiguration, we see the purpose of Moses and Elijah's final appearance: to decrease and diminish as Jesus was exalted to be heard. Jesus... would not be sharing his platform with the representatives of the Law and Prophets.
