It deals with the difference between the Greek idea of truth: basically the correspondence theory, which is, to my mind easily Platonised, and the Hebrew idea: trustworthiness and reliability.
Now, take this dichotomy to Genesis 1, noting its being the source of many points of reference throughout the Bible, and consider the difference between a Greek, (neo)Platonic view of truth; which allows the easy Idealist slide into all sorts of non-truth variations: the framework hypothesis, Genesis 1 as 'impression', rhetorical counter to ANE myths (meaning Enuma Elish, invariably). Could a Hebrew think in that fashion?
I think not. Truth as trustworthy conduct, or words: seems to sit with Genesis 1 being an event narrative, immune to the pressure of Western thought that would undermine it; words God has spoken to Moses, and God saying as much (see below).
This makes arguments about 'genre' trivial in their missing of the point so egregiously. Particularly the point reinforced in those reliable people: Jehovah and Moses! The question of taking the Bible 'seriously' without taking it as proceeding from the mouth of God in the detail that we are given undoes the seriousness instantly.
Particularly as one considers God speaking directly to Moses in Exodus 20, attempting, for the cool crowd, to put aside the Graf-Wellhausen hypothesis and its kin, and consider the text in terms of the Hebraic understanding of truth as relational, not as something apart from the God who authors it, apart from people (creator and creature) in loving (and therefore trusted) relationship (which is one of the major implications of the text, in grand recursive fashion). From Exodus 20:1
Then God spake all these words, saying...for in six days the Lord made the heavens and the earth, the sea and all that is in them, and rested on the seventh day; therefore the Lord blessed the sabbath day and made it holy.Ending with Exodus 20:11.
And that's it for Bird.
