One of the first things I saw pop up on Facebook that the press was saying about ABB is that he is a fundamentalist Christian. This struck me as highly unlikely when I first read it. Besides the obvious fact that a Christian wouldn’t randomly kill innocents, there are very few “fundamentalists” Christians in Norway. (This also indicates that the press doesn’t understand the terminology it uses.) Belief in Norway is low to begin with, and what belief there is is mostly found within the traditional denominations of Norway. While there are, I’m sure, orthodox (small o) Christians in Norway, they wouldn’t generally be described as “fundamentalist” unless someone is using that word to mean any orthodox (meaning something like creedal) Christian. But if they mean fundamentalist in the sense that word has come to mean (for better or for worse) in America, then I suspect most fundamentalist in Norway probably go to mission churches founded by fundamentalist mission organizations from America.
But it turns out ABB is not a Christian. At the most he is what you might call a cultural Christian. He is not a believing Christian himself, but he respects Europe’s Christian heritage. (This is a position you see commonly on the nationalist right, because there is a lot of unbelief on the nationalist right.)
