So did the Apostles.
He has the power to show that He is talking with Moses and Elijah, no doubt to whom He would have been able to talk to in Heaven anyway. Normal human beings do not have these powers. Normal human beings are told NOT to talk to the dead and to NOT get involved with those who do.
Jesus was setting a bad example, and we shouldn't get involved with him?
You twist Scripture and take things out of context just to provoke. I feel sad for you.
