When is a Religious Belief Delusional?

[Abaddon_ire]

nevertheless, there seems to be an overarching concept of human goodness that unites them all.

If by "unites them all" you mean only that the concept applies in all cases, perhaps there is.  That is a hypothesis that could be checked.

Yeah, "unites" the 30,000 odd denominations of christianity alone. That is one hell of a borked definition of "unity".

One might be forgiven (LOL) for thinking that an omni-everything deity would be able to transmit his/her/it's/housecat's message clearly, but no. The omni cockwomble is a total failure at communication.

My cat can communicate better than that and I don't even have a cat. This is how stupid the whole lot of theism is.
