Thought provoking words from Walter Brueggemann*:

The issue of the authority of the Bible is a perennial and urgent one for those of us who claim and intend to stake our lives on its attestation.  But for all of the perennial and urgent qualities of the question, the issue of biblical authority is bound, in any case, to remain endlessly unsettled and therefore, I believe, perpetually disputatious.  It cannot be otherwise, and so we need not hope for a “settlement” of the issue.  The unsettling and disputatious quality of the question is, I believe, given in the text itself, because the bible is ever so endlessly “strange and new.” (The phrase is an allusion to the famous essay of Karl Barth, “The Strange, New World within the Bible,” in The Word of God and the Word of Man.  New York:  Harper & Brothers, 1957, 28-50.)  It always, inescapably, outdistances our categories of understanding and explanation, of interpretation and control.  Because the Bible is, as we confess, “the live word of the living God,” it will not submit in any compliant way to the accounts we prefer to give of it.  There is something intrinsically unfamiliar about the book, and when we seek to override that unfamiliarity we are on the hazardous ground of idolatry. (5)
