To believe what the bible says about itself is not an act of blind faith as some would have you believe. I have found that most Christians are unaware as to how the canon of scripture as we know it came to be. The reason for this is because it would be difficult for "Pastor Dan" to do a sermon on how the Roman Catholic Church is the whore of Babylon, but, uh, they uh, did put the bible together for us so we could use it to denounce them, A-amen??? Here is a decent account of the canonization process:
