Do all readers have authority to interpret text or do scholars have greater authority based on their greater expertise?
For some texts, yes. Especially if its a historical text or a text in another language than the one the reader knows. We all have some authority for certain things based on our personal inventories. For example, I have authority with texts written by 21-year-old caucasian girls from the subburbs of America. I might be able to interpret this type of text better than my English professors to a certain extent. I might not, however, be able to compare it to similar writings of the past because I haven’t studied them or had the opportunity or time to do so to the extent that my professors have.
So what about the Bible? The Bible is supposed to be accesible to everybody of all nations, but I don’t think it really is. I think that the nature of Christ exists outside of the Bible often, and those who are illiterate can still feel that faith without reading the Bible. Scholars in this case, Biblical scholars, do have more authority over the Bible as a historical text. If we were to sit down and read the Bible front to back it wouldn’t make any sense.
