You mean Jesus came down and told you personally to pick the King James Version of the Bible to believe in and not the Douay-Rheims? Or do you mean you believe Jesus says so because you read it in the Bible?
I assume you mean the latter. Do you see the circular reasoning here? Logical fallacy.
We're back to square one. If you believe Jesus told you in the Bible, well...How do you know the Bible is true? By what authority?
Can you show me where in the Bible it says which version of the Bible to use? Or whether or not to include the deuterocanonicals? Or which New Testament Scriptures are inspired and which ones are not?
