The hallmark of dogma and posturing in religion (specifically Christianity) is the belief in exclusivity as pertaining to absolute truth(s).
My controversial opinion is that some day people will realize that there actually
is a spiritual dynamic and that there is a superior (supreme) being in control of all things.
I believe that it will take the realization by humanity of the utter futility of our ability to solve the problems that vex us.
If there is any good news in my fundamentalist views, it is that Jesus won't be sending people to Hell. People will end up there only by rejecting Him...which only a fool would do. Atheists quite rightly reject a fallible religion attempting to legislate morality. Its an entirely different matter to reject God Himself, however.
Of course, to be fair, maybe I will get sent to Hell for rejecting atheism!
