I have heard poorly educated ministers who understood the Bible better than people who went to seminary. I am thinking of a cousin of my late mom’s in particular. I doubt if he had a high school diploma because back then, the schools only went through the 8th grade. If they wanted to go to high school, they had to board with someone with the school or people who lived nearby. He knew the Bible, though.
He may have been the greatest biblical scholar who ever lived, I didn't know him. However, he was probably a very good man who personally interpreted the Bible AS HE UNDERSTOOD IT.....Nothing necessarily wrong, just probably incomplete.
