When Martin Luther published his 95 Theses in October 1517, he had no intention of starting a revolution. But very quickly his criticism of indulgences became a rejection of the papacy and the Catholic Church emphasizing the Bible as the sole authority for Christian faith, radicalizing a continent, fracturing the Holy Roman Empire, and dividing Western civilization in ways Luther—a deeply devout professor and spiritually-anxious Augustinian friar—could have never foreseen, nor would he have ever endorsed. From Germany to England, Luther’s ideas inspired spontaneous but sustained uprisings and insurrections against civic and religious leaders alike, pitted Catholics against Protestants, and because the Reformation movement extended far beyond the man who inspired it, Protestants against Protestants. The ensuing disruptions prompted responses that gave shape to the modern world, and the unintended and unanticipated consequences of the Reformation continue to influence the very communities, religions, and beliefs that surround us today.

How Luther inadvertently fractured the Catholic Church and reconfigured Western civilization is at the heart of renowned historian Brad Gregory’s Rebel in the Ranks. While recasting the portrait of Luther as a deliberate revolutionary, Gregory describes the cultural, political, and intellectual trends that informed him and helped give rise to the Reformation, which led to conflicting interpretations of the Bible, as well as the rise of competing churches, political conflicts, and social upheavals across Europe. Over the next five hundred years, as Gregory’s account shows, these conflicts eventually contributed to further epochal changes—from the Enlightenment and self-determination to moral relativism, modern capitalism, and consumerism, and in a cruel twist to Luther’s legacy, the freedom of every man and woman to practice no religion at all.  

With the scholarship of a world-class historian and the keen eye of a biographer, Gregory offers readers an in-depth portrait of Martin Luther, a reluctant rebel in the ranks, and a detailed examination of the Reformation to explain how the events that transpired five centuries ago still resonate—and influence us—today.
