I'm confused about the American Republican party

The Tenth amendment says, "The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people."

So if it is not spelled out in the Constitution, then it is reserved for the states to deal with, or if not there then by the people directly.

Except that the 14th Amendment binds the states to the bill of rights. Each state can no more establish religion than the Federal government can.
