Yes, what does ontological truth have to do with utility? Utility's not the measure of religious faith.Of course ideas should be tested, the God idea being no exception. If faith in God didn’t work for me personally, I would have abandoned it years ago: and more easily than contemporaries of Copernicus abandoned the Ptolemaic model of cosmology. The simple and well evidenced fact is that faith works, for millions of people, every day; and isn’t labelling reliance spiritual principles “a trick to get through tough times” simply to take a utilitarian approach? Something I imagine you’d be perfectly comfortable win other contexts.
Faith does "work" for millions of people all over the world, but the facts, legends, and theology they have faith in vary, and are often contradictory.
How do contradictory claims support anything?
How would one test a god-claim, since 'working for me' is epistemically useless?
