To understand how the Reformation changed the world, you have to understand Martin Luther. Which is why the new biography by Eric Metaxas is a must read. October 31st marks the 500th anniversary of the event regarded to have started the Protestant Reformation: Martin Luther nailing his 95 Theses on the door of the Castle Church in Wittenberg. Now, as my BreakPoint co-host Eric Metaxas writes in his outstanding new book, Martin Luther: The Man Who Rediscovered God and Changed the World, Luther’s theses probably weren’t posted on the church door until two weeks later, and even then, it may not have been that defiant act it’s often portrayed to be. Still, what did happen on that date was that Luther sent to the Archbishop of Mainz a letter expressing his concern about the selling of indulgences. As Eric relates, Luther had no idea how that letter and the events that would follow in its wake would change the world. Even today, most people, apart from some historians, fail to fully appreciate the impact of Luther’s ideas and actions. Protestantism is, as the title of Durham University’s Alec Ryrie’s book puts it, “The Faith that Made the Modern World,” and without Luther there’s no Protestant Reformation. The problem is that history is too often told in dry and inaccessible ways, at least to non-academic readers. What’s been needed to appreciate Luther and his legacy more is a book that takes the history seriously by situating Luther in his historical and theological context while still being enjoyable, even fun, to read. And that’s where Eric’s book succeeds. In many ways, “Luther” is a kind of sequel to Eric’s “Bonhoeffer: Pastor, Martyr, Prophet, Spy.” Both books are about world-shaping historical Christian figures who, motivated by their conscience and conviction, took enormous risks against the most powerful institutions of their time. And not coincidentally, both Luther and Bonhoeffer were from eastern Germany, as is Eric’s mother. I note this fact not in any way to detract from his accomplishment. On the contrary, Eric’s personal connection is one of the book’s strengths. As is, of course, Eric’s trademark engaging style, full of clever turns of phrase and humor that makes the incredible story of Luther all the more accessible. Often, biographical subjects don’t feel human. They are, as was famously said of Robert E. Lee, “marble men.” But not Eric’s Luther. He’s quite human, for better and for worse. Early on, you practically feel Luther’s anxiety and dread over his own sinfulness. Which helps to make sense of the terror he felt during that fateful thunderstorm that ultimately led him to become a monk, abandoning the legal career his father had mapped out for him. All of this is important backdrop to understand why Luther’s study of Romans and the idea of justification by faith was more than an academic exercise for him. For Luther, it was more like getting water from a rock in the middle of a desert. And yet throughout Eric’s book, we learn that Luther was far from being an angel, or for that matter, even pleasant a lot of the time. He was someone who, as a church historian once put it, never knew a moderate moment in his life. Eric writes of Luther’s “execrable fireworks” that were not only directed at his enemies, which included Protestants as well as Catholic prelates, but also at innocent parties, in particular Germany’s Jewish population. As he did telling the story of Bonhoeffer, Eric depicts Luther’s humanity while simultaneously putting it in its proper historical context, one in which there was a perfect storm of church corruption, political instability, and technological change. Eric gives us a feel for both Luther the man and his world. Both are necessary to understand if we are to see how Luther changed the world. Obviously, Eric’s a personal friend and a BreakPoint colleague. But I promise it’s nowhere in my contract to promote his latest book! This recommendation is driven only by the simple facts that Luther is too important a historical figure and Eric tells the story too well not to recommend this book.
