"This book probes the beating theological heart of Luther's evangelical theology." — Michael J. Chan, Ph.D., Concordia College In his Galatians commentary of 1535, Martin Luther insists that "our theology" relies on the proper distinction of two kinds of righteousness: Alien and Proper. In relation to our Creator, we freely receive our "alien" righteousness from Christ who has obtained it for us through his death and resurrection. In relation to humanity and God's created order, we practice a "proper" righteousness by actively fulfilling God's commands that set down the form and pattern for good human living. The Alien and the Proper “ helps us to appropriate Luther’ s theology as our theology as well.” — Mark Mattes, Lutheran Bible Institute Chair of Theology, Grand View University Luther posited that this distinction was the key to understanding our humanity. His regular use of this anthropological principle, particularly when applied to justification by faith, the nature of sin, and the proper practice of God's gift of humanity, demonstrates its centrality and importance. In The Alien and the Proper, five authors examine the historical development of Luther's Twofold Righteousness and propose ways in which it can continue to serve Christians today. Through these essays you will learn about Luther's radical divergence from medieval theological formulations, and you will discover what it means to be human. Essays by: David A. Lumpp Charles P.
