So I went back to my notes from the All Nations courses: anthropology, sociology of religion, folk religion, and it became clear to me. You’re not going to like this, but I’ve come to believe it’s true: The situation only makes sense if you consider a separate entity called “American Christianity” which is an entirely separate religion to Christianity. Not a branch of Christianity, not a form of Christianity, but something with absolutely no connection to Christianity at all. It’s a separate religion. And what is the goal of this religion?
Go for it; look at it phenomenologically, look at it sociologically, and what do you see? Basically a syncretic folk religion, based primarily on American nationalism, an expression of the “pervasive religious dimension of American political life”. (Bellah; see also “Civil Religion in America”) Its purposes are basically civil and political. Its morality is taken from a highly selective and individualistic reading of the Old Testament, and it mixes in bits of consumerism, Zionism, Republican political values, and corporatism for good measure. Add to this an almost romantic sentimentality concerning the person of Jesus, much like the contribution of Catholicism to Vodou religions, and suddenly it all makes sense.
