Distinguishing between belief and action is an obvious corollary to religious freedom. For example, you're allowed to believe that God wants you to perform human sacrifices or take a dozen wives or not pay any taxes or whatever, but you don't get to act on those beliefs. Surely someone as educated as the good bishop is well aware of this rather basic point.
Attempts by temporal authorities to restrict the practice of Christian virtue and the freedom of Christians are not new and historically have come from pagan or officially atheistic rulers.
History also tells us that this never ends well.
