Here are a bunch of questions that stand out to me when I read discussions between Mormons and other Christians regarding the authority of scripture:
1. Does the authority of scripture always depend on facts not fully described in the text?
2. Does the authority of scripture depend on whether it was (1) received by revelation, (2) by its uniquely accurate representation of facts, (3) something else? (If (3) what?)
3. What is the basis of the special authority of scripture over other religious texts?
4. What determines the importance of any particular idea, thought, or account in scripture?
If you have a few, let me know what you think.
