Your understanding of history is a bit skewed.
The separation of church and state is a myth based on a letter written by Thomas Jefferson and has no bases in the Constitution (Jefferson was in France at the time of the writing of the Constitution and had little direct influence on its development). It was activist judges that forced the separation of church and state not the founders. The Constitution as written only excluded religious test to the Federal Government not the states.
Several of the states at the time of the founding had state religions. One or more states (I cant recall which) excluded Catholics from holding public office. Catholics did not predominate in any of the states. Catholics are estimated to have been 1.6% of the population at the time of the Revolution.
The Catholic Church is against revolution as a general rule not the Revolution.
