i think that the main issue is where we place authority for the "ultimate ground of truth"... it was the project of the enlightment christians to rationally defend their faith, so they looked around, saw their scriptures, pointed to it and said, "there, let's make that be the ultimate ground for truth". it has been the curse of christianity since then to try to show how the bible is the ultimate ground of truth: either through the infallible-inerrant route or otherwise...
the bible was written by numerous authors, in many different regions, for many different reasons. not all were meant to be literal and historical. there are books that aren't included in the bible for reasons of church politics...
truth seems to emerge within communities through their internal conversation with themselves (was that redundant? sorry) ... that as we talk about what we believe to be truth with those around us, those ideas interact with the standard of truth in our community... we challenge and converse with each other, and a general truth emerges... when someone new comes along and has some new ideas to offer, those add to the truth, and the truth (or their understanding of the truth) consequently "changes". this is the story of the various saints and sages who have come along to add to or better explain the truth to their community. i'm not saying that truth is relative. i'm saying that our understanding of the truth is relative. i believe that there is an ultimate truth, but that we each have our own relative way of approaching it.
that's what we have in the bible, the ideas that those communities believed about themselves and others. tradition has carried that down to us and influenced the way we do life...
the problem i think is that people approach each other with different understandings of truth and how it exists. since there are those who believe that the bible is the revealed and literal word of god, that for them constitutes the standard of truth.
true conversation exists when others are sensitive to the beliefs of others and are geniunely involved in communicating their ideas and learning from others....
sorry so long. did that make any sense?
