When is a Religious Belief Delusional?

[Neo-Scholastic]

Mathematical realism fares no better as it is well recognized that the ontology of numbers and morals is significantly unlike the ontology of existents like this desk, or a supposed god, thus unless you can reconcile those differences, your argument to analogy fails.  

And therein lies the rub. Despite how many time believers tell you that we do not define God as just one more thing in a world of things, you still try to compare God to all manner of contingent things, like desks and invisible dragons. So yes, my analogy holds perfectly fine. One type of immaterial object, a mathematical one, with another immaterial object, a Prime Mover/Necessary Being/Etc.
