What beliefs would we consider reasonable for a self proclaimed Christian to hold?

[Astreja]

I've said many times here that I can not prove He exists to the satisfaction of those who deliberately blind themselves to the truth.

You seem to be incapable of treating us with sufficient respect to consider that we are not withholding truth from ourselves on purpose -- we are merely utterly unconvinced by the batshit-insane claims that you and other believers make about a being that we sincerely believe to be no more than a figment of the human imagination.

For that libel against non-believers, I think you should slander the Holy Spirit in your dreams one night very soon, and lose the salvation you think you have.

Although I am quite convinced that you never possessed "salvation" in the first place and are not losing anything of actual worth.
