An old truism goes that when Catholics sin, they go to confession, but when Protestants sin, they go out and buy a book (it didn’t say anything about what Mormons do). If that rule still applies today, then Protestants are doing a whole lot of sinning. Buried in this BBC News story about how Wal-Mart will soon be stocking an entire line of Bible-based action figures like Goliath and Sampson (a simultaneously surprising and yet terrifying prospect), is this little nugget: Sales of religious books in America went up 5.6% in 2006. And apparently Christian book-buyers spend half as much again on books as the average American. So whatever those atheists, and other non-Christian religious types are doing with their time, it doesn’t appear to be reading.
