That is itself not biblical. Sola scriptura does not exist in the Bible.
"Every word of God is pure...Proverbs 30:5"
God is pure and His words are pure. Every word in the Bible is not the word of God.
The Bible is also not God.
Inspiration is not God.
The Gospels even are not direct quotes but narratives of what Jesus would have, or was known to have, or is believed to have said. Ancient writers quoted others based on their familiarity with the person. Their quotes are not direct quotes.
The Bible is what God revealed to lesser or greater degree, expressed in human terms, human emotions and human language.
The only way to know whether what we read is of any validity is to do textual criticism and this is possible only to a limited extent.
Some groups who claim Christ as their Saviour have an idolatrous relationship with the Bible.
More importantly, they have an idolatrous relationship with their own interpretation of the Bible, which is not far removed from self worship.
How so?
You have been very straightforward in saying that most of the history in the OT are just stories meant to teach us something and that a lot of Paul's writings are contradictory and suspect. Therefore, I understand how you don't have the same degree of respect for Scripture as we do, but how is believing that Scripture is the inspired Word of GOD idolatrous?
I have never seen Bible believing Christians in any church pray to statues of the Bible, or expect miracles by touching it's image, or pray to perceived images of it in the sky.
