In the five hundred years since the publication of Martin Luther's Ninety-Five Theses, a rich set of traditions has grown up around that action and the events that followed, and a reader trying to find his way among them needs a map.

This dictionary, edited by Mark Granquist with contributions from leading theologians and church historians, covers Luther's life and thought, the key figures of his time, and the various traditions he continues to influence. Entries are current and the scholarship is recent, which matters in a field that has moved considerably. A reference volume.
