No, and Christ is my proof.
Christ returned and interacted with His disciples like a normal man. he ate, talked, left foot prints, shook hands, and even ate with his disciples, yet he was able to go through material doors as if he were a ghost. They could even put their fingers through the holes in his hands made from the nails that held His body on the cross. Yet he was not as them no more.
He was, and is after all God and as such He can suspend the very laws of physics if He wants to. See, we live by the laws He put in place, and like the earth before and after the flood, He can change them anytime he so chooses.
