You would have thought that John would have known that freedom of religion requires separation of church and state.
Other than that, he was, certainly welcome to all of his opinions.
I'm sure that the Taliban, for instance, has many such opinions about the opposite of freedom of religion.
There is no separation of church and State in the Constitution. That didn't happen until the 20th century when the Supreme Court added it to the Constitution through judicial fiat.
It is pretty clear in the Constitution that there will be no state religion. As well as just common sense. There is not freedom of religion unless the state is out of the business.
True but that doesn't contradict that there is no separation of church and State in the Constitution.
