Let's be clear: the stories are not about someone coming back into the present mode of life. They are about someone going on into a new sort of existence, still emphatically bodily, if anything, more so. When St Paul speaks of a “spiritual” resurrection body, he doesn't mean “non-material”, like a ghost. “Spiritual” is the sort of Greek word that tells you, not what something is made of, but what is animating it. The risen Jesus had a physical body animated by God's life-giving Spirit. Yes, says St Paul, that same Spirit is at work in us, and will have the same effect - and in the whole world.
