"Abingdon Pillars of Theology" is a series for the college and seminary classroom designed to help students grasp the basic and necessary facts, influence, and significance of major theologians. Written by noted scholars, these books will outline the context, methodology, organizing principles, primary contributions, and key writings of people who have shaped theology as we know it today. "Martin Luther would be shocked to hear that he is appearing in a series called pillars of theology. To be sure, the professor of biblical interpretation with a doctorate in theology was a theologian. In fact, teaching theology for thirty-four years at the University of Wittenberg brought into Luther's large household, managed by his wife Katharina von Bora, the only salary he ever earned. Still, like most theologians, Luther never thought of himself as having a theology. A theologian becomes a pillar of the discipline in the estimation of admiring readers, but they are not the focus of this book. My purpose is to lay the groundwork and identify the pieces that were later used to construct what is now called Luther's theology." From the book
