It can't happen as long as we have the Establishment clause...
However, you *could* go to Germany, a good *Protestant* country (though I think the Lutherans, like the Anglicans/Episcopalians, Orthodox, and even Monophysites, all believe that *they* are the true Catholic church).
@AnneHoney Yes! See https://en.m.wikipedia.org/wiki/Religion_in_Germany
Germany has (or had, when I worked there long ago) a church tax (as part of what you're required to pay when you work). If you didn't assign it to another church, it went to the Lutheran church.
@SomeMichGuy 75.5 per cent or around three quarters of the Bavarian population are Christian. 54.8 per cent of them belong to the Roman Catholic Church and 20.7 per cent to the Evangelical Lutheran Church. A quarter of the Bavarian population belong to a different religion or do not identify with any religion at all.
So I was right. I believe the rest of Germany is primarily Evangelical/Lutheran
