For both things to be identical (the same) they must share all the defining variables and methods.

Variables are nouns and adjectives describing the object.
Methods are actions which that object can perform and actions which can be performed on that object.

To say this...

In reality, the case is that the corpse is the body deprived of its animating principle, the soul.


...and base upon this that a corpse is the same thing as a dead body is like saying that a 10 year old Honda Civic 1995 EX is the same thing as a 10 year old horse because both share the same variable of being 10 years old.

To show that they are different we only must find one variable or a method which does not belong to both a dead body and a corpse. This is not difficult to do!

When I die, I will leave behind a corpse and/or my dead body. Five thousand years later (given that resurrection did not, yet, occur) my corpse will no longer exist (being subject to natural decay). If my dead body is the same thing as my corpse that would mean that my dead body will no longer exist! And we know that not to be true! Because my dead body will still "sleep" awaiting the resurrection; my dead body will still exist despite the contrary of my corpse.

I said it once before (somewhere) that the only way to use the Bible to imbue any importance into a corpse is if there is either: an explicit commandment (thou shall or thou shall not) or if this importance can be implicitly derived from an explicit docrtine (like the Trinity). When it comes to corpses... I just don't see that happening.
