Personally, I don't see it as an issue. We are fully/purely physical beings. Our consciousness and self-awareness is a result of the work of the brain. Therefore, if a person dies and his brain fully decays and a new brain is created that is perfectly identical to the original brain just before death, then the exact same consciousness will be recreated and the person will, in actuality, be resurrected.
The copy will be different only in the sense that different atoms and different cells are being used. But the practical value of the atoms and cells are identical so there will be identical sentience. The copy will not feel like a copy; will not be able to separate or distinguish its present sentience from the sentience of the original.
It only seems wrong if you assume that there is some intangible, mysterious, ethereal aspect to our consciousness. As sentient beings we are the product of our brain. Reproduce the brain and you reproduce the person. Is it a clone? Yes. Does that invalidate it being a resurrection? No. Clone vs Resurrection is a false dichotomy. It is a clone AND a resurrection. (not that I believe the bible)
Let me illustrate it this way: If you lend me a 100 dollar bank note I owe you 100 dollars. Do I have to return to you the exact same hundred dollar bank note in order to repay you? If I give you a different bank note are you going to cry foul saying it's not a valid repayment but just a clone of the original note? No. Yes, technically I'm returning a "clone" but it has the exact same value indistinguishable from the value of the original. Similarly it's the value, the effect, of sentience - identical sentience - that counts and not the technicality of a spatially non-identical body. It is the identical construction of the brain - the mind - that counts.
Another illustration that is a bit closer: If your house got destroyed and you built another house with different materials on the exact same spot is it wrong to say you rebuilt your house? Re-built, Re-surrect.
Resurrect comes from a Greek word that means stand again. So once the same person - the same sentience, the same mind - is able to stand again, to live again - by whatever means - then the person has been resurrected. So perfectly cloning the brain can be viewed as a means of resurrecting rather than a disqualification or an invalidation of the resurrection.
