One of the main ways that ideas of resurrection differ among Christians (conservative, moderate, liberal, emergent, emerging, etc.) is whether the resurrection body is (1) the same physical body one possess while alive, with the same atoms and so forth; (2) a physical body not necessarily composed of the same atoms; (3) a body that is physical, but made of “transformed” atoms, not composed of what we think of as matter; (3) a purely spiritual resurrected body, composed of subtle forms of matter; (4) purely a symbol of the moral and spiritual rebirth of a person during his or her lifetime; (5) a symbol of something that cannot be described in any accurate fashion whatsoever, so it’s best just to not think about it too much.
