So--your claim is now that the Bible has no spiritual authority. It's just a bunch of words written by man.
“So—your claim is now that the Bible has no spiritual authority.”
The Bible has spirtual authority insofar as it is an accurate witness of the Apostles and of Jesus Christ.
This is why chopping books because it teaches things you don’t like (as Luther did), is so corrosive.
Again, there is no either/or. Scripture AND Tradition.
