When is a Religious Belief Delusional?

[robvalue]

How far beliefs deviate from reality has to be important, I expect. Also, the reason for being wrong.

If I believe my car keys are on the hook as usual, but actually I put them on the table, I hold an incorrect belief. But this is a simple slip of memory, which will be rectified as soon as the mistake clashes with reality. If I continued to believe it was on the hook even after seeing that it wasn't, then I'd be deluded.

If my keys are on the table because someone else moved them since I put them on the hook, then I have an incorrect belief, but it's just a matter of not having up-to-date knowledge. It would again get corrected.

If I believe my keys are always in my pocket in spirit, and I can use that spirit to lock and unlock the door even without the physical keys, then I'm mistaken and deluded. This would cause a clash with reality as my belief would get challenged any time I didn't have my keys; unless I only ever "used" my spirit key and so didn't ever actually lock or unlock it.
