Catholic canon law. It includes punishments for heresy etc. My ancestor was the first Christian authority to execute heretics (Emperor Magnus Maximus). That the Catholic dictatorship isn't as effective now, is due to the Protestant Reformation. But Protestant Reformers were just bad Catholics who refused to obey the Pope. They had their own local authoritarians that they preferred. The Enlightenment and the French Revolution took the sting out of the Inquisition, and the demise of the Papal States in 1870 de-powered it. The Concordat with Mussolini in the 1920s re-funded it ... with the gold that Germany still wants to get their dirty hands on.
So Pr126 ... have you been to weekly confession in the Catholic Church? Have you honored the Church of England? Fail at the first and the Catholics will burn you. Fail at the second and my other cousin, King Henry VIII ... will cut your head off.
