Where did that remark come from? Mormonism, as anyone can easily find out, is one of a number of Christian sects which came into being in the USA in the nineteenth century. It differs from mainstream Christianity on certain technical points which Dawkins would at least pretend not to understand. So why write "four if you count Mormonism"? Why not "five if you count Mormonism and Christian Science"? Or "ten if you include Mormonism, Christian Science, Christedelphians, Jehovah's Witnesses, Reformed Judaism, Shi'ite Islam, Strict Baptists, Celtic Orthodox, Unitarians and Quakers?" Does Dawkins think that the Mormons' adoptionist Christology is so far removed from the mainstream as to constitute a separate faith (while the Jehovah's Witnesses' arianism is not?) Or is he playing a numbers game, saying that the Church of Jesus Christ and Latter-day Saints is so numerous as to count as a religion in its own right, distinct from "Christianity". (But then, why not "Four if you include Catholicism"?) We never find out. Like Melchizidec, it comes from nowhere and it goes nowhere. It popped into Dawkins head and he wrote it down. It makes me doubt whether our author is fully in command of his brief."Four if you include Mormons". Honestly, you might just as well say "Britain consists of three countries: England, Scotland and Wales – or four if you include Tooting Bec.
