This thesis explores the evolution of the biblical concept of imago Dei. Written from the perspective of Christian theology, the thesis engages select Jewish and Christian voices in analysis of the shared theological premise that the human person is created in the image of God The discussion will begin with the scriptural origins of the concept, drawing upon exegetical interpretations as well as the early perspectives of the Rabbinic and Patristic period. It will then offer a comparative account of the contributions of Maimonides and Aquinas, in their intellectualist conceptions of human distinctiveness. From there, the discussion will turn to the Christological appropriation of the concept in work of Karl Barth and then to the covenantal, dialogical interpretation of David Novak. In both of these thinkers, we will observe a rejection of the intellectualism of Aquinas and Maimonides in favour of relational interpretations which are, in their integrative understanding of the person as body and soul, more consistent with the biblical - and Rabbinic - view of the person. The desire for an integrated view of the person will also emerge as significant when the discussion turns to feminist engagements with the concept, which also emphasise the inclusive potential of imago Dei. The thesis will conclude with a consideration of the enduring relevance of the concept of imago Dei in the context of contemporary Jewish and Christian theology.
