As far as we know, none of the founders used the term “separation of church and state.” What they said was, “Congress shall make no law respecting an establishment of religion or prohibiting the free exercise thereof.” In other words, government is not in the religion business. There will be no state religion. Each citizen has the right to practice his or her religion, whatever that religion is. All of these add up to separation of church and state.
Well stated! I couldn’t have said it any better. Thank you!
