The doctrine of the imago Dei, that human beings are created in the image and likeness of God, is an endlessly fascinating topic. Not only is it a central doctrine to Christian life and practice but also touches, perhaps even helps to form, every other doctrine of the Christian faith in one way or another. We do not think about God, in a Christian sense, as any other than the God who creates humanity in God’s image. However, many of the details of this claim and what it means for human beings are left undefined by Hebrew and Christian Scriptures and it is not even mentioned in the creeds. This space leaves room for exploration. So the quest for what it means for human beings to be made in the image and likeness of God has never ceased to occupy theologians, clerics, and the laity alike. In this Companion, Peppiatt charts the developments of the doctrine through the ages, summarizing each position and perspective up to the modern day. This volume offers a compact but rich overview of the various ways in which this doctrine has been and is understood as well as pointing readers to further questions for consideration.
