BU professor Stephen Prothero on our fighting words

Boston University religion professor Stephen Prothero talks about his latest book, “The American Bible: How Our Words Unite, Divide, and Define a Nation.” “I’ve always been fascinated by the rabbinic tradition in Judaism, that to be a Jew is to argue about what it is to be a Jew,” he says. “It seemed the same--to be an American is to argue about what it is to be an American.”
