As theologians across confessional divides try to say something significant about human dignity in our contemporary society, there is fresh interest in the ancient Christian doctrine that the human being is created in the 'imago Dei'. Robinson examines the 'imago Dei' debate through three giants of twentieth century theology - Karl Barth, Hans Urs von Balthasar, and Jürgen Moltmann. Fresh analysis of ecumenical contributions places the development of the doctrine in the context of the ongoing process of ecumenical dialogue on the dignity of the human person.
