Before I go on I’d like to note that I’m playing the role of Devils advocate. I don’t think this is right or true. I’m just seeing how an idea like this an be replied to. Anyway here goes nothing.
Would it be justified to persecute heretics and non catholics along the lines of Arab Dhmini laws? As in extra taxes, illegal to convert others to your religion and in effect being made second class citizens. My reasoning went that heresy and false religions harm the souls of people and should be stamped out. Looking at history, Dhmini style laws seem most effective at this (just look at once Christian North Africa) and thus should be applied to heretical and non catholic beliefs. When combined with strong religious education and missionary work this would bring as many souls as possible to the Church.
As I said before I don’t think this is moral but am looking for a more substantial reply. God bless and thanks.
