Catholic philosopher Thomas Storck argues that, once a society becomes "Catholicised" and adopts the Church as the state religion, it is further morally bound: "'the just requirements of public order' vary considerably between a Catholic state and a religiously neutral state. If a neutral state can prohibit polygamy, even though it is a restriction on religious freedom, then a Catholic state can likewise restrict the public activity of non-Catholic groups. "The just requirements of public order" can be understood only in the context of a people's traditions and modes of living, and in a Catholic society would necessarily include that social unity based upon a recognition of the Catholic Church as the religion of society, and the consequent exclusion of all other religions from public life. Western secular democracies, committed to freedom of religion for all sects, find no contradiction in proscribing polygamy, although some religions permit it, because its practice is contrary to the traditions and mores of these nations. A Catholic country can certainly similarly maintain its own manner of life."
