I'm not sure exactly how intentional it was, but Stuart Gordon's Dagon's contains a sequence of immense and disturbing power to anyone who knows about the participation of the Spanish Catholic Church in the oppression of the people: when Capitán Cambarro rebels against the established order of Imboca in order to bring in the worship of Dagon, he and his pals smash up the Catholic Church and murder the priest. Such things happened during the founding of the Spanish Republic in revenge for the complicity of the Church with the corrupt and brutal Bourbon monarchy; churches were destroyed and their priests slain. That might shock a Christian reader, but the people of Spain had reason to feel that the Church had betrayed them. Dagon gives us a just a little taste of that historical episode.
The people of Imboca also feel betrayed by their Church but for a different reason: they'd been a fishing town and now there's no fish, so the town is slowly dying and the Church offers the people nothing but unanswered prayers (suddenly I'm reminded of Night in the Woods and another town that was healthy only so long as there was a resource to be extracted.) When Capitán Cambarro claims that his new god will actually answer their prayers, they listen! Sure, it means in the long run that the human inhabitants of Imboca end up forced to cede their humanity to become "children of Dagon", but the film dares to suggest that the system does work in a way. There is a strange society here in Imboca but a functioning one, and it makes sense to the citizens (at least those with significant dialogue.)
It's fairly plain that a moderate fraction of U.S. Christendom has become, in its way, something like the Esoterica Orde de Dagon seen above. There's a multitude of organizations and groups and sects and individual worshippers with strange new beliefs but who retain some outward façade of Christianity, some of the trappings and symbols, rather like Capitán Cambarro still making use of the Catholic church for his new Dagon cult. The substitution is possible because the new beliefs offer some practical approximation of the central promises of Christianity: a spiritual home, a sense of family and destiny, and the promise of life eternal if you do everything the right way. Paul Marsh, or Pablo Cambarro, gets to have a long life in the Sea as one of the children of Dagon (presumably) with his new wife who is also his sister, Dagonic customs being what they are, with access to a mountain of gold treasures. Arguably that's better than being a dweeby techbro perched uncertainly atop a pile of Internet-startup "wealth" and constantly fretting about his portfolio.
It suddenly occurs to me that Pablo might decide to bring Imboca into the Internet age, come to think of it.
