When Martin Luther nailed his 95 theses to the door of the Castle Church in Wittenberg on October 31, 1517, no one suspected that he would fundamentally shake Christianity. Who was this man we remember today, 500 years later, as a great reformer? Maja Nielsen takes us into a dramatic time of religious upheaval. Her focus is not only on Luther's new teachings and their impact on the church, state, and society. She places the person of Martin Luther, with all his strengths and weaknesses, at the center, bringing to life a wise and courageous man whose story still captivates us today. Included are a chronicle of Luther's life, book and film recommendations, and museum addresses. Margot Kässmann, ambassador of the EKD for the Reformation anniversary in 2017, provides brief, concise comments explaining what shaped Luther's thoughts and beliefs.
