This book argues that a primary purpose of theological discourses is to construct piety or spirituality. If this is the case, theologians need to constantly inquire into the kind of piety or spirituality which their work may construct. Drawing from some important moments in the development of Christian theology, such as the development of the Christian doctrine of God in the early church, the role of material things in the Christianity of medieval Europe, some elements of contemporary postliberal theology, and the theology of inculturation in Africa, the book argues that theological discourses that appear to be orthodox and innocuous may actually construct forms of piety that may diminish human flourishing. The book therefore calls for an ethics of theology intended to ensure that the theologies we construct help in developing a piety that is conducive to human flourishing in the modern world, especially for Africans, who have suffered and continue to suffer unspeakable dehumanization. The book proposes that a theology that may contribute to the flourishing of Africans in the modern world is one that constructs an interdisciplinary spirituality that takes both the spiritual and the scientific seriously.
