What I have said is that Scripture is meant for all people in all time. It was not meant solely for its immediate audience.
But is scripture meant for people to distort it's purpose? Literalism is not an approach of the past, it arises from modern Christian thought, in circles where believers discarded God as an experience, in favor of God as an object, there by limiting god, and killing him all at once. Literalism arose from believers wanting to keep up with the Joneses in the emergence of the scientific way of thinking.
Literalism attempts to rewrite the truth of
why, found in myth, with a Godless
how, and attempts to interpret scripture that arose from deep reflection into reality, into interpretation so removed from it.
When people speak to me of God as an object, they are trying to tell me that "a colorless green idea has wings". To read scripture properly you should engage it on the experience it is describing, and if you assume that the early readers of Genesis, found purpose and meaning in how they came into existence, I'd have to wonder why Yahweh did not perish like the sky Gods.
God is found in why we exist, and not in how.
Literalism allows a believer to read Isaiah, and ignore his message of renewal, and social justice, in favor of "hey, Isaiah was killed to tell us the world was round." Literalism allows one to say the opening book of Genesis, which tells us about our own fallen nature, about the God of order, and purpose, is about talking snakes and lions who ate nothing but carrots.
