The five lectures that make up this book were delivered at Boston College in 2019 as the Duffy Lectures in Global Christianity. In them the author begins from the assumption that if the Christian God is to have global significance, it will not merely be a matter of Christianity accepting cultural and religious diversity and retreating from its mission of converting the entire world to its own way of thinking about God. The conversion to tolerance and hospitality towards other modes of belief and practice marks a watershed for Christianity, but only as a transition to straighten out its past in the face of a graver, commoner concern: the care of an earth abused by human civilization and devalued by organized religion. The author approaches this question from a broader consideration of the origins and functions of gods in minds and from there suggests grounding metaphors of the divine and its relationship to the natural world in a nothingness beyond being and becoming.
