Really all the Constitution says is that the Federal government can not establish a national church.
You would be correct ..!!!
And .. what most people don’t realize .. the left is trying to ESTABISH A NATIONAL CHURCH - ISLAM - which is not even a CHURCH .. it’s a CULT.
Actually a careful reading of the 1st Amendment shows that what it does is take the question of the establishment of religion out of the Federal jurisdiction and reserve it to the states. "Congress shall make no law respecting an establishment of religion..." Congress cannot establish a national church or forbid a state from establishing a local state religion. There were indeed a few state established churches for a number of years after the ratification of the 1st Amendment.
And that it can’t interfere with anyone’s worship or religious expression.
