It is claimed that God wrote a book called the Bible, and it is generally admitted that this book is somewhat difficult to understand. As long as the church had all the copies of this book, and the people were not allowed to read it, there was comparatively little heresy in the world; but when it was printed and read, people began honestly to differ as to its meaning. A few were independent and brave enough to give the world their real thoughts, and for the extermination of these men the church used all her power. Protestants and Catholics vied with each other in the work of enslaving the human mind. For ages they were rivals in the infamous effort to rid the earth of honest people.
