>I dont think Christians are accused of being narrow minded for that reason. You can't use the Bible as proof of your position when its the very thing you are trying to prove, ie when its point of view is what you are trying assert in the first place.

Interesting point, although it is tangential to the line of discussion. However, there has to be a basis for assertions made, and for Christianity the basis is the Bible. Perhaps some indirect proofs can be made, but ultimately (of course) it gets back to faith.
