Religion of the NRF
 

Are they Catholic? I see news reports that state they went to Mass, but I thought they were Lutheran.

Norwegian Royals are Lutheran, not Catholic. I don't think being Lutheran means not having any church services.

Oh sorry... I thought only Catholics called their services Mass.

I think so too, but I also think I misunderstood your question.

I saw that, too - I think the photos were just incorrectly captioned, or the captions were poorly translated. The NRF are Lutherans, and Lutherans don't call services masses.

well yes, I was confused about that too.
Several captions said the Royals were attending the "mass"; which is not correct...
...but actually many people nowadays say "mass" when they mean church services... no matter if they talk about catholic or protestant church services.
Maybe that's also why the caption says "mass". At Norwegian pages you don't find that expression. They only say "church service" - which is correct.

I'm not quite sure about the situation in the Lutheran Church of Norway (don't know if that's the right name) but in Finland the Lutheran church service has been called "mass" for a few years. Might be that way in Norway as well.
At the beginning it sounded a bit odd to me because I linked the word "mass" with the Catholic Church (no offence here on my part) but now I'm used to it.

The Norwegian royal family is Lutheran, as been mentioned above. In the Lutheran churches there are two different kinds of religious services, one is (in Norwegian) gudsteneste, the more common church service without communion/nattverd, the other is messe when there is a communion/nattverd.
