In Spirituality and Reform, Calvin Lane has accomplished two goals. Lane has synthesized and explained dozens of theological movements stretching from the Gregorian reforms of the eleventh century to the Moravians and Pietists of the 1700's and he has challenged the artificial boundaries that scholars use to separate historical periods. His book unites the waves of theological reform rocking Latin Christendom. Lane has written a solid book to explain and emphasize the constantly evolving and consistent nature of Christian theology in pre-modern Europe.
