3 points. 1} The Church has always and everywhere--at least up to the robber council Vatican II--condemned the notions of "religious liberty and "separation of Church and state". 2}"Secular" governments can not endure without recognizing Christ as their King. It is not possible for men to be long virtuous or to govern themselves without the assistance of sanctifying grace and complete submission to the Deposit of Faith as entrusted exclusively to the Catholic Church. All the great civilizations which turned away from the Divine and natural law eventually fell. The United States is no different, with its rampant abortion, perversions, marxism, and pornography. 3} When you refer to "conscience", it is implicit and presumed that the conscience is properly formed. Anyone who believes that infanticide ought to be available does not have a properly formed conscience.
