The religious restraint in the 1st is pretty specific. Look it up. What exactly does it say, ODH?
Yes, it says Congress. But, it wasn't until (for the most part) the issue of incorporation began to be litigated in earnest, did the federal judiciary begin to assert itself into the matter of religion and it's separation from the state.
The refusal of some states to recognize some individual rights (as outlined in the BOR), is precisely what led to the 14th Amendment.
