The problem is that sacred texts like the Bible (other examples might be the Pali Cannon in Buddhism or Vedas and Upanishads in Hinduism) do not contain "flat contradictions". If people hundreds of years apart write down conflicting ideas that later get complied together by another person/group who are using those texts for non-logical spiritual guidance, in what way is that a meaningful contradiction? Also, the idea that wisdom must be strictly rational is a modern, scientific standard that these texts fundamentally disagree with.
If you redefine words and ignore logic - you can salvage anything, sure.
I'm not sure what's the point tho. If you start with abandoning logic - you cannot later return back to using it. Starting with 0==1 you can prove anything.
If Bible gets away with contradictions - you can't then accept the conclusions and use logic on them. The moment you abandoned logic you are left without it forever. Full-blown postmodernism. Nothing is true and everything is true.
So by your standard, the works of Nietzsche are worthless because he was a strident anti-rationalist, and his works of literature contain many (mostly purposeful) contradictions?
Rationalism, which you seem to be an ardent supporter of, is a strain of philosophy. We all have some epistemological system we live by, so discrediting philosophy on its whole is not an option.
