"Luther's Economic Ethics" is a scholarly book that examines economic ethics in the context of the teachings of Martin Luther. In light of the challenges posed by the 2008 economic and financial crisis, the necessity for a well-founded ethical orientation in economic actions becomes evident. The book highlights the often-overlooked aspects of Luther's economic ethics and offers an in-depth analysis of his writings on economic topics. It demonstrates how Luther's views on ethics in business are not only historically relevant but can also provide valuable insights for contemporary discussions on ethical behavior in the economic sphere. The author, Hans-Jörn Prien, offers a well-informed perspective that takes into account both the biblical roots and the theological developments that contributed to the formation of Luther's economic ethical beliefs. This book is a valuable resource for anyone interested in exploring the ethical dimensions of economics.
