There’s great variation within Western Europe and that has to do with the particular historical experiences of different countries in different regions, from the Reformation period onwards. Broadly speaking, the Germanic world – Germany, Scandinavia, areas that were much more influenced by Lutheranism – had the formation of State Churches, which were really Departments of State in a meaningful sense. Religion becomes part of the Ministry of Culture’s responsibility, so there is a sort of public religion which you’re not required to belong to, but which nonetheless has certain public functions.
In the case of Germany’s reactions to the right-wing nationalist movement, there are Lutheran bishops or Catholic bishops who are, by virtue of their office, entitled to speak on that subject. You have something similar in the case of the Anglican establishment within the UK. Of course, there are lots of smaller Protestant denominations and sects there – in that sense, it’s more like the United States. Yet, the Church of England is still a public authority in a way that has no analogy in the United States. Catholic regions are, again, something different, in that the ultimate authority in religious matters is the Pope, who, unless you happen to reside in Italy, does not speak in the name of your country at all, but in the name of the Church.
