This definitive analysis of the theology of Martin Luther surveys its development during the crises of Luthers life, then offers a systematic survey by topics. Containing a wealth of quotations from less-known writings by Luther and written in a way that will interest both scholar and novice, Lohses magisterial volume is the first to evaluate Luthers theology in both ways. Lohses historical analysis takes up Luthers early exegetical works and then his debates with traditions important to him in the context of the various controversies leading up to his dispute with the Antinomians. The systematic treatment shows how the meaning of ancient Christian doctrines took their place within the central teaching of justification by faith.
