This brief introduction to Luther's theology connects Luther with the evangelical tradition. Paul Hinlicky, one of today's leading Lutheran theologians, explores six key areas of doctrine for which Luther is regarded as an authority, correcting common misconceptions of his thought in light of the whole of his theology. This work regrounds evangelical mission in a new evangelism and catechesis on the basis of Luther's doctrine of the atonement as "joyful exchange." In addition to its classroom utility, it will be of interest to evangelical pastors and church leaders.
