There is a lot of confusion surrounding the term ‘evangelical.’ Who are they and what exactly do they believe? If you have questions about evangelicals, there is no one better to ask than Mark Noll, a world-renowned scholar specializing in the history of Christianity in the United States and one of the foremost experts on the evangelical movement in America. Mark’s most recent book, entitled “Evangelicals: Who They Have Been, Are Now, and Could Be,” was co-written with leading historians David Bebbington and George Marsden. Together they explore the past, present, and future of a movement in crisis. In this first part of our conversation, we discuss the history of the evangelical movements, critical inflection points such as the Fundamentalist-Modernist Controversy of the early 1900s and the Lausanne Congress on World Evangelization which was spearheaded by leading figures such as Billy Graham and John Stott.
