“The argument that follows [in the book] is that the mainstream churches, both liberal and evangelical, abandoned large pieces of their Christian heritage by working so hard to make their faith practical and relevant to everything from the personal lives of ordinary citizens to the affairs of one of the most powerful nations in modern history. In a word, by trying to make religion relevant, American Protestants ended up trivializing Christianity” (D.G. Hart, The Lost Soul of American Protestantism [Lanham, MD: Rowman and Littlefield Publishers, Inc., 2002], xvii-xviii).
