In a world that is more religiously diverse than ever before, our coworkers and neighbors may well be adherents of other faiths. But how many of us really grasp the similarities and differences between the major world religions? Comparative theology is one increasingly important way to bridge this gap, especially for Christian leaders and professors, but also for lay people and students. Veli-Matti Kärkkäinen introduces the nature and work of comparative theology, then delves into a detailed doctrine-by-doctrine comparison of Christian teachings with those of historical and contemporary Judaism, Islam, Buddhism, and Hinduism. With every doctrine, he first presents a summary of consensual Christian belief and then orients the reader to the distinctive teachings of other faith traditions, highlighting parallels and differences. Ideal for students, ministers, instructors, and lay people interested in interfaith dialogue, Doing the Work of Comparative Theology distills the comparative-theological rigor of Kärkkäinen's Constructive Christian Theology for the Pluralistic World series into an accessible and user-friendly textbook. Readers will not only learn basic methodology but also begin to undertake the actual work of comparative theology.
