Standardization of Spelling correlated with increased literacy

Ok so here is the topic I am interested in but I need you guys' help with a compelling thesis. I'm having trouble because the two events do seem to be correlated and I want to argue for causation but at best any evidence is circumstantial and the arguments rather circular.
How can I improve this statement?
The increase of literacy during the Renaissance made greater standardization of written language necessary to preserve meaning and understanding.

Influence of King James

I went to see the exhibit in the library about the King James Bible several weeks ago. While I enjoyed seeing the old Bibles, I, like Will, found the display about the impact of the King James Bible on the English language and modern culture most interesting. I was reminded of the university forum presented by Dr. Norton on the King James Bible. If you didn't get a chance to watch it, I would highly recommend it. In essence he talks about the impact of having a standardized Bible. Suddenly, people expected a particular tone for scripture and, to some extent, if it didn't match that, it wasn't just different, it was wrong.
