Dustin quoted Alpha God by Hector A. Garcia
Another means of enforcing mental submission is by prohibiting the reading of religious texts. There is a long history of the Catholic Church prohibiting the masses from reading the Bible. For instance, Pope Innocent III wrote in 1199: The mysteries of the faith are not to be explained rashly to anyone. Usually in fact, they cannot be understood by everyone but only by those who are qualified to understand them with informed intelligence. The depth of the divine Scriptures is such that not only the illiterate and uninitiated have difficulty understanding them, but also the educated and the gifted.
