In this significant book Mark C. Mattes critically evaluates the role of justification in the theologies of five leading Protestant thinkers -- Eberhard Jungel, Wolfhart Pannenberg, Jurgen Moltmann, Robert W. Jenson, and Oswald Bayer -- pointing out their respective strengths and weaknesses and showing how each matches up with Luther's own views. Offering both an excellent review of recent trends in Christian theology and a powerful analysis of these trends, Mattes points readers to the various ways in which the doctrine of justification has been applied today.
