Understanding Divine Communication in Biblical Inspiration

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.  

• How is divine inspiration of the Scriptures different from the automatic writing they have in cults?
• It really does not bother you that you don’t know who wrote 74% of the New Testament? It could have been anybody.
• Is it okay for me to comply with a new requirement for clergy in my denomination to pledge fidelity in writing to its statement of faith?
• If the Word of God is powerful, how can a preacher who once taught the Word faithfully go rogue theologically?
