Beyond doubt, the Bible for many Americans is, as Martin Marty phrases it, an “icon” as well as an object of study. With no American group is this more the case than with evangelicals… Evangelicals, by reputation and self-definition an antiliturgical folk, have nevertheless made a formulaic phrase, “the Bible says” (or its variants, like “my Bible says”), an all but essential part of the sermon. The iconic place of the Bible accounts for the fact that so many evangelicals profess belief in scriptural inerrancy, yet know little about the book’s actual content. It also helps explain why many different bodies of evangelicals continue to insist that they follow “the Bible alone” and are not influenced by historical or cultural conditioning, as they go their mutually exclusive ways in doctrine and practice.
