Several Canadian journalists writing of their experience in the USA said that religion plays a greater part in life there than here. One article I remember about Texas, the journalist said she had to make up whatever church she belonged to just to stop people asking that question, which denomination she was. She’d never been to a church then or since, but “church?” was what everyone asked. Of course, in LA or NYC, no such issues.
You can get a sense of what a country thinks about religion in general by how it figures in politics.
So, similarly, religion in politics seems to be much more prominent in the USA. I attribute the Canadian indifference to the fact that, given the proportion of French-Canadians, immigrants from places like the Phillipines, Italy and Portugal, Catholic is by far the largest denomination; plus Canada has a much higher immigrant population from Asia (east Indian and Chinese) who are not Christian. You don’t see articles on politicians’ faith, where or when they go to church, etc. - except the current prime minister who seems to be trying as hard as he can to convert us to the American political-religious trends,
Similarly, I don’t see much about european politicians and their religion - simply because many countries have one predominant religion, and unless the politician were, say, Mormon or scientologist, nobody would care which sect they belonged to. Even Northern Ireland, religion is just a code for ethnic extraction - Irish are catholic, English colonizers/immigrants are protestant. All over the first world, but especially for the catholic church which demands a heavy committment of its clergy, the levels of clergy and levels of church attendance are falling.
Plus, only the USA has such a strict prohibition on government having any role in religion. In Europe, religion has been part of the “establishment” for so long it has become part of the existing low-level class warfare, and prominent church leaders often earned the same enmity as rich aristocrats. The church, for example, was a persecuted as the nobles during the French Revolution. The pope was as reviled as the French or Spanish in England and other protestant countres that even went to war to prevent being overrun by catholic country forces. (Think Guy Fawkes…)
