By no means the majority but only some original colonies, fleeing from religious persecution, applied their own versions of religious persecution and discrimination as per the Delaware constitution. Most colonies gave no heed to any religious conditions or establishment, save for the then normal superstitious mentionings. They were being primarily founded for reasons of trade and profits.Jem does bring up an excellent point. To say the United States wasn't founded on Christianity, or even religion, is really a technicality. The original colonies (and many states afterward) sure made it their point to call out religion in their charters.
