Not the first amendment which was binding only on Congress passing laws. You are simply denying that the words of the constitution mean what they say. Thanks.
That is why Mass, Va, and other states had laws allowing the establishment of religion and why the 14th specifically expanded coverage to the states.
I can't imagine what your point is here. The 14th had something to do with pre-constitutional laws about religion? How weird.
Quite the contrary the words of the 1st amendment clearly say "Congress shall make no law...." How does pointing out the actual words deny them?
State sponsored religions continued after the adoption of the Constitution and even a cursory glance at history shows this. I can't imagine how you could not know this.
