Book excerpt: Paul Helm breaks fertile ground in this survey of theological anthropology in the Reformed tradition. Acknowledging the rich patristic and medieval heritage available to Reformed theologians, Helm works through a representative range of authors and materials during the period 1550 to 1750 in order to identify certain ways of thinking as well as elements of development and change. Addressing topics like the relation of body and soul, faculty psychology, and moral agency, Helm develops a compelling picture of Reformed thought on human nature that is sure to encourage more studies on this topic for years to come.
