We have heard talk enough. We have listened to all the drowsy, idealess, vapid sermons that we wish to hear. We have read your Bible and the works of your best minds. We have heard your prayers, your solemn groans and your reverential amens. All these amount to less than nothing. We want one fact. We beg at the doors of your churches for just one little fact. We pass our hats along your pews and under your pulpits and implore you for just one fact. We know all about your mouldy wonders and your stale miracles. We want a this year's fact. We ask only one. Give us one fact for charity. Your miracles are too ancient. The witnesses have been dead for nearly two thousand years.

In 1473 Copernicus was born. In 1543 his great work appeared. In 1616 the system of Copernicus was condemned by the pope, by the infallible Catholic Church, and the church was about as near right upon that subject as upon any other. The system of Copernicus was denounced. And how long do you suppose the church fought that? Let me tell you. It was revoked by Pius VII. in the year of grace 1821. For two hundred and seventy-eight years after the death of Copernicus the church insisted that his system was false, and that the old Bible astronomy was true.
