"The Catholics have a pope. Protestants laugh at them, and yet the Pope
 is capable of intellectual advancement. In addition to this, the Pope is
 mortal, and the church cannot be afflicted with the same idiot forever. The
 Protestants have a book for their Pope. The book cannot advance. Year after
 year, and century after century, the book remains as ignorant as ever."
                        [Robert G. Ingersoll]
