 ::I too have never before heard of a religious idea of ""salvation from biological death""; our sources don't mention any such thing, and I'd say practical experience should tell us that biological death is a certainty. Even when a religion believes in some form of eternal life - and for some subsets of Christianity that's eternal life in a resurrected body - that's still only after biological death, not instead of it. There are some exceptions where immortality without biological death is indeed believed possible or achieved (the latter only in mythological beings, of course), but I'm not aware of any such associated with salvation.
