Why cling to this ol' body that can be seen as an earthly treasure which is prone to corruption anyway?
I have already argued for why cremation sends a less than ideal message. Perhaps those arguments are not convincing, but they are what they are.
I think an important subtlety is often overlooked about Jesus' resurrection that speaks to the point you raise. When Jesus was resurrected, did He get an entirely "new" body? Not really. The graveclothes were empty -
Jesus' resurrection body was formed out of His old one. If that were not so, we would still have Jesus' 'corruptible' body in the tomb. And what about the marks of the crucifixion in his hands.
It is pretty clear that Jesus' old body was not "tossed out" - it was "re-worked" or transformed. The old body was not "discarded", with a new one replacing it. Instead, the new sprang from the old.
This is relevant to the topic since cremation implicitly, albeit subtly, denies this important truth. By cremating the body, you send the world the message that God is
not going to redeem his fallen creation. Why does cremation send such a message? Well, when you
intentionally burn away the "old", you are, by that very action, declaring the old to be "valueless" and worthy of incineration.
That denies an important theological truth - God is in the "repairing" business, not in the "replacing" business.
