" Is there anything left to take literally? " probably not Cofty ! it is the refuge of Bible believers, once you prove how very silly a Bible story is, then, "it must be metaphorical."
The problem is twofold with this, one, metaphors are open to lots of different interpretations, and two, if it nearly all comes down to metaphor, then it really is all a matter of faith, or belief, and that means trusting that something is true, with zero evidence, which, to my mind is indistinguishable from delusion, and Delusion is a very serious mental problem.
That means that all Bible believers suffer from a serious Mental Problem.
As a lot of memes say " change my mind".
