If the person is very much dead, and the clone is so close to the original that he initially thinks he is the original, can't this be a form of resurrection?
My thinking on it is this that a clone doesn't automatically count. That's a wholly new person, just the same genetics. What counts, overall, is the memory. Maybe 'soul' if that's in your verse. Take the brain out the corpse, put it in a clone, then sure it's the same person, but if there's no memory transfer, that's just a new person. How would he think he is the original, anyway? A lot of scifi just glances over that.
Back to Star Quest Online, when a person died, to justify respawning, they had some mumble jumbo that basically everyone has a implant that takes a snapshot of the brain, uploads it to subspace (thus allowing near infinite travel range and speed) which is then sent off to the nearest receiver which then holds the info, gets the recent medical data from their central data infobanks per empire (Not!Federation, Not!Klingon, Not!Romulan), makes a clone, then downloads the info into the clone.
In that regard, at least, the info-memory thing works, plus has the weird side effect of uploads and all that entails (Scions, Downloads, Uploads, Virches, Copies, Technological Afterlifes, Enhanceds, etc that the game didn't go into, but
Orion's Arm did).
In Space Station 13, most people who are revived do so via cloning their dead body, which I assume copies the brain and somehow memories; but in practice, in the game, you become a ghost you can play around with (as to not just be sitting there on your butt at a black screen) so it relies on soul-ghost stuff (and you have to manually reenter your body, if you ignore the call...you get recycled). Or your body is fed to a plant and a new pod-body is grown. Or your brain is stuffed into a Man-Machine Interface and then into a Cyborg or AI wetware core. Those work.
Reviving the corpse as well, in any medium, works overall. Though I hope the brain hasn't decayed to a massive point....
