Far from commanding any special respect or protection from the State, religions must be exposed to relentless criticism, like all non-rational traditions and beliefs. Some religions will survive this contest between tradition and modernity, between reason and revelation, as Christianity, Judaism and Islam have done for centuries. Others, such as Marxism and Scientology, will fall by the wayside. In America, the Constitution, with its prohibition against the establishment of any state religion and its absolute defence of free speech, demands a robust competition between faith and reason and among the religions themselves. And in the end, as America’s surprising piety clearly shows, it is not just society but also religion that emerges stronger from the refiner’s fire of competition, criticism and even insult.
