Denmark, Iceland, Norway, and Finland have state churches (Lutheran). And of course there is also the Church of England (Anglican).
But I have read that England is losing the Aanglican Churches as they go with the ordinariate and become Catholic.
I wasn’t aware of the others since I believe there are also other churches (Catholic) in those countries, but perhaps I am mistaken.
Of course, we have the Saudi and Mid East area too where both Catholic and Christian churches are being destroyed and the people killed.
