Published on the occasion of the quincentenary of the Reformation, this encyclopedia extends beyond the Reformation to include the Reformed tradition, more radical movements (e.g., Anabaptists), the Counter-Reformation, and the history and present state of Lutheranism. In addition to the alphabetical entries—most brief but informative, each concluding with a brief bibliography—there is substantial scholarly apparatus, including appendixes that outline Luther’s paradoxical doctrine of the Two Kingdoms and details about Lutheran bodies in North America. The 475 entries include doctrines and controversial topics (e.g., Sabbatarianism), religious phenomena (e.g., Marian piety), events (Marburg Colloquy), places (Slovakia, Wittenberg), and persons (Hieronymus Emser, Huldrych Zwingli). Also covered are subjects like printing, hymns, music, and family life. Luther’s teachings are examined in articles ranging from "Views of Women" to "Self-Love." A series of articles address why the Reformation mattered, in its time and in various religious traditions since. Among the most interesting entries are "Legends Regarding Luther" and "Postcolonial Luther."…. [T]his is a worthwhile set. Summing Up: Recommended. Lower-division undergraduates through faculty and professionals; general readers.
