Q: do you, Christian, claim that God exists, rather than you believe that he exists?

[Angrboda]

There is still the problem of "god" being poorly defined.

This is a recurrent theme of yours, that a concept has to be clearly defined to be meaningful. I think this is a canard. We use words without clear definition all the time without difficulty communicating. Language is very slippery on the aspect of meaning, and to demand greater clarity on this one word because it has a special place in your belief structure strikes me as special pleading. Take the sentence, "The ball came to a stop at the bottom of the stair." We don't understand the reference ball and its full meaning until we reach the end of the sentence; the action doesn't resolve itself until the end of the sentence. But we don't feel any anxiety about the vagueness of meaning prior to the end of the sentence. Vagueness and ambiguity is, to my mind, what makes communication in language so powerful. If it didn't have this looseness about it, we'd hardly be able to talk in anything less than book length sentences with any clarity.

So while I can appreciate that you may not have an intuitive grasp of the concept and find it puzzling, whether because it wasn't a part of your culture or whatever reason, I think you're demanding things of this word that you don't ordinarily require of other words that you use. That's special pleading.

(And as a mathematician and philosopher, I can tell you that some of the most interesting things are vague and depend on such slipperiness. Demanding that specific definitions not be vaguely defined appears both rather stodgy, and an example of the fallacy of the beard.)
