Sometimes same-sex marriage has been described as a natural outcome of the removal of sex from the realm of morality. Sometimes it has been praised as a wonderful transgressive rebellion, good because it helped undo bad Western norms. Sometimes it has been described as a useful expansion of an old idea, helping preserve the marriage culture. Occasionally it has been promoted as a way of returning ethics to sexual relations, drawing gays and lesbians away from support for the demoralization of sex, to which, it is claimed, they were forced by the repressions of a premodern morality that lasted into the modern world.
In other words, the arrival of legal recognition of same-sex marriage was over-determined in America. And that’s why I think it makes a terrible object for the Catholic Church to pick as the synechdoche for all the objectionable things in contemporary society. Our problem as Catholics isn’t that same-sex marriage somehow uniquely represents Western society’s recent turns; our problem is those turns themselves: the disenchantment of the world, the systematic effort to hunt down and destroy the last vestiges of old metaphysical and spiritual meanings in the world.
