" The real purpose of religion—at the popular level—was to unify the populace. Let everyone worship his favorite god in some niche or other, but let’s all sacrifice at the same altar, climb the same steps, and wander through the same colonnades. Let the Jews have their god, by all means—who’s stopping them?—and let us all have ours. And no provincial exclusiveness, please. "
