How Is Biblical Inspiration Different from Automatic Writing?

Questions about how biblical inspiration differs from automatic writing, whether or not we don’t know who wrote 74% of the New Testament, signing a man-made statement of faith, and how, if the Word of God is powerful, someone who taught it faithfully can go rogue theologically.
