function and purpose are man-made concepts

[ΛΟΓΟΣ]

So, you deny that Christianity claims to be the solution to death?

And instead of presenting a scientific plan to reverse aging or something, you instead want us to accept Pope's cookies in our mouth as the body of Christ

u dont know why those simple rites exist
it isnt the process for an afterlife only rites of initiation 
marriage is one of the parts of it, it isnt to sell rings you dummy, it's part of the unification between adam and eve
if you do not believe in the resurrection then the spirit made flesh is lost after death, that's faith. i can't tell you that you are immortal
