<<In short, if Genesis 1 is considered to be primarily non-historical in
character, I want to know how this heremeneutic can be applied to the
rest of Scripture consistently without opening the door to denying the
historical character of all of Scripture.>>
Your initial premise assumes that saga is perforce "non-historical." This is
the either/or error I pointed out to Glenn some time ago. It is a product of
the Enlightement which has filtered down to us from Greek culture and
interrupts our hermeneutic.
The ancient Heberews were not either/or thinkers. Thus, to apply such a
standard to the Bible is to risk serious error vis-a-vis Scriptural
interpretation.
Have you read Pinnock, "The Scripture Principle" and Bloesch, "Holy Scripture:
Revelation, Inspiration & Interpretation"?
I'd recommend both of these for compelling and complete answers to your
questions. They are two of the best evangelical theologians writing today.
