The essay argues that religion has not simply disappeared from modern life. Its older vocabulary has weakened, but many of its social functions remain. Public life still contains sacred objects, forbidden speech, purity tests, rituals of belonging, moral pollution, heresy, confession, and expulsion.
In this neutral reading, the point is not that secular politics is secretly identical to religion. The point is more modest: groups still need shared meanings that tell members what counts as good, dangerous, shameful, loyal, polluted, or unforgivable. These meanings help people recognise who belongs inside the group and who stands outside it.
Climate change and Donald Trump work as examples because both subjects often operate beyond ordinary disagreement. For many people, they become tests of moral identity. The question is not only what someone thinks about policy or evidence, but what their belief seems to reveal about their character, loyalty, and social world.
The Catholic–Protestant conflict gives the older template. Catholicism preserved sacred authority through institution, hierarchy, ritual, and mediation. Protestantism challenged that mediation and relocated authority into scripture, conscience, discipline, and inner conviction. The essay suggests that modern politics still repeats versions of this pattern.
The central claim is therefore simple: social orders survive by turning shared beliefs into moral reflexes. Once that happens, the group does not need constant external enforcement. It polices itself through taboo, shame, loyalty, suspicion, and the fear of being cast out.
