Here's the "New Christian Science Textbook" from Matt Bors. Click to enlarge and study.
Man is the religious animal. He is the only religious animal. He is the only animal that has the True Religion –- several of them. He is the only animal that loves his neighbor as himself and cuts his throat, if his theology isn’t straight. He has made a graveyard of the globe in trying his honest best to smooth his brother’s path to happiness and heaven.
~ Mark Twain
Three quarters of the American population literally believe in religious miracles. The numbers who believe in the devil, in resurrection, in God doing this and that — it’s astonishing. These numbers aren’t duplicated anywhere else in the industrial world. You’d have to maybe go to mosques in Iran or do a poll among old ladies in Sicily to get numbers like this. Yet this is the American population.
