Probably of last week, actually — I am reading it from my subscription copy of The Spectator, issue dated Aug. 27. Anyway, the article is “Why America is not a Christian Country,” by Tom Fleming (editor of Chronicles).
Closing sentence: “If there really were a ‘Christian America,’ Hollywood would be broke, and the ashes of both political parties would be reposing quietly in the dustbin of history.” (I suspect Tom wrote “trashcan,” but the editors Britishized it.)
Sorry, can’t find the whole thing on the web. If you can, send me a link & I’ll post it.
