I would be most interested in knowing your source for claiming that Paul did not blieve in the Bible. Both He and Peter repeatley refer to Scripture and in 2 Timothy 3:16&16 Paul defends Scripture to Timothy, telling him: All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: That the man of God may be perfect, throughly furnished unto all good works.
Maybe you should actually think about this before you react. Or are you one of those that actually believe that 'if the KJV was good enough for Paul, it's good enough for me'? What version of Bible did Paul carry? Red letter edition? Complete with concordance and atlas? Heck he didn't even carry a pocket size set of scrolls, now did he?
Or maybe he had a Gideon's New Testament?
