If the bible is gods word and a manual for how we should live our lives then it should be clear and uncomplicated, not hidden in metaphor.
Assumptions:
1. 'THE' bible exists discreetly.
2. A specific 'god' exists without specification and delimitation.
3. The god has word(s) which are discernible and may be contained in #1.
4. We have lives which are discreet and meaningful.
5. There is a way we should live our lives.
6. Also, there is a way we should not live our lives.
7. This one is sort of hidden, but it can be inferred that living our lives purposefully is assumed to be the right way. In other words, the argument of "should" is taken for granted. As if it is weighed against other should's, without validating that there is a should in the first place.
8. Given the above, we know the bible to be a relatively finished product. Therefore any question of how it 'should' be is in itself a contradiction. The bible is exactly the way it is. Only an interpretation about it can be clear/uncomplicated. Or perhaps they are referring to the translation process? Or even to how this 'god' of theirs should have written it in the first place. The language is way off, that's for sure. And again, the bible itself is not clear and uncomplicated. They are referring, I presume, to the stories within the bible. This contains additional assumptions, chiefly that they are somehow meant to be understood. So, until the meaning given the bible seems clear and uncomplicated, the asserter of the above would not rest.
9. Hidden in metaphor...? The bible can not possibly be hidden in metaphor. "The bible" here refers to the idea of an overarching theme to the collection of books in the common modern protestant cannon. That such a theme actually exists in the first place is open to much scholarly dispute.
10. Common usage of words slips a bit, but not too much. So common usage can be assumed.
It is clear, in the least, that this statement is a logical fallacy of the "does not follow" variety. I would say:
Versions of books called bibles are exactly the way they are. What way are they?
My answer, as many of you know, is that the way they are is a hodgepodge of remarkly violent tales, appropriated folk-lore, and ancient semitic behaviour code.
