What the bible "says" isn't religion or doctrine or belief.
Interpretation is.
Proved how?
There is not just one christian church.
Ask yourself "why?"
Here is a logic puzzle easily solved!
Example: If a math book with equations were inerrant what would happen if every student in the world worked the equations?
Answer: all students would achieve identical solutions.
What happens when the bible is read by christians all over the world?
Read on...
Until Martin Luther came along there WAS one central "universal" (i.e. catholic) church) christian source authority.
Did you know (of course you do) the Catholic Church did not use "the bible says" as the source of THEIR AUTHORITY.
No.
The universal christian church used INTERPRETATION as their source of power. This was called Magesterium.
If the Church said something was True----it was automaically True.
Maring Luther snipped this cord of authority.
What Luther let loose on the christian world was a substitute idea: Sola Scriptura.
Do you know what that is? (Sure you do.)
Each individual bible reader needed ONLY THE BIBLE ALONE to know God's true teaching.
And you know what resulted?
Here is where the Logic Puzzle is presented and solved!
IF the bible alone was god's truth----every believer would AGREE with every other bible reader...LOGICALLY SPEAKING.
But, guess what? No surprise here!
Instead, we got thousands and thousands of DIFFERENT interpretations.
The result?
Denominations.
Separate and disagreeing churches.
Christianity's history itself PROVES LOGICALLY the bible is NOT the source of inerrant Truth.
What about Jehovah's Witnesses?
Now, this is very very interesting.
While pretending to use Martin Luther's sola scriptura (bible alone) the Watch Tower Society uses catholic Magesterium instead!
They have it both ways!
Yet, combining two failed fundamentals (two source inerrancies) for them still only yields Dumb Opinions.
Even they too fail. "Adjustments" must be made in the same way using a broom and dustpan "adjusts" a broken mirror.
None of these ideas succeed logically to produce INERRANT truth.
Logically, opinion cannot ever be True. It can only be opinion.
Christianity is, was and always shall be: Opinion.
Why? There is nothing inerrant about any foundational books, writings, pronouncements or opinions.
