Think ''Calvin'' and you think ''reformer.'' But a major---often neglected---role of Calvin as a reformer was ''preacher.'' Weaving together historical detail and theological substance, Parker describes the theological considerations that moved Calvin to preach the way he did, considers Calvin's view of the preacher's office and the congregation's duty, and chronicles Calvin's distinctive expository method. ''A solid presentation of material not currently available in English,'' says Donald McKim. 240 pages, paper from Westminster.
