That really is laugh out loud funny. Throw out books that the Bereans had as a part of their Scriptures because Luther didn't like those books, ignore the fact that Christ never said a single thing against the existing selection of books that were included in Scriptures at the time, nor did any Apostle, and then laud the Bereans. I don't recall anything about Bereans first selecting what subset they would accept and then searching the Scriptures.
So you refute what Paul said?
