Huh?
Religions are either true in the manner in which they connect the dots between morality/enlightenment here and now and immortality/salvation there or then or they are not.
You are either in sync with the one true path or you are not.
And, if you think you are, you are either able to demonstrate this to others or you are not.
You will die, right? And you do think about what happens to you after you die, right? And you do think about choosing behaviors here and now that will enable you to embody that which you would most like your fate to be there and then, right?
You tell me: What assumptions could possibly be more basic in regard to religion down through the ages?
What are you saying, that the only important assumption about religion is that in regard to morality here and now and immortality there and then, all that matters is what you happen to think is true here and now in your head?
Indeed, ILP is often bursting at the seams with members who preach one or another “general description intellectual contraption” rendition of that.
And, even in regard to this, they, like you, invariably refuse to explore with me the manner in “I” here is but the embodiment of dasein out in a particular world historically, culturally and experientially.
Instead, their whole point is embedded in the belief itself. That’s the part that comforts and consoles them. Next to this, what they believe often pales in importance.
Or, sure, so it seems to me.
