The Bible is the only source that is to be righteous period, all others are false.
“You can’t be an historian with such whomper-jawed nonsense.”
This is the argument and belief from 99% of believers so I assume it is the same with you? No? You do not believe the Bible is the sole unique righteous authority?
If so, then by Christian standards you are not a true believer because literally word for word this is what everyone faithful does indeed believe...
“You do not believe the Bible is the sole unique righteous authority?”
I have no clue what your definition of “sole unique righteous authority” encompasses. Your use of “righteous” gives you away. I bet anything you think you are going to sneak that in and try to trap me with something.
Being a Christian, I believe that the Bible is inspired of God, and that it is the only volume inspsired by God. That is, he has not inspired other books purporting to show the way to salvation, etc.
As such, it is a very tiny spectrum of what can be considered “righteous authority.” A history book written by Winston Churchill, for example, could very well be considered a righteous authority, since he was honest, knowledgable, did his research, and was brilliant.
Luke, in writing his account in the New Testament, said he used and compared manuscripts to arrive at accuracy. He obviously considered those manuscripts “righteous authority” and we don’t have them now.
