The question of realism - that is, whether God exists independently of human beings - is central to much contemporary theology and church life. It is also an important topic in the philosophy of religion. This book discusses the relationship between realism and Christian faith in a thorough and systematic way and uses the resources of both philosophy and theology to argue for a Christocentric narrative realism. Many previous defences of realism have attempted to model Christian belief on scientific theory but Moore argues that this comparison is misleading and inadequate on both theological and philosophical grounds. In dialogue with speech act theory and critiques of realism by both non-realists and Wittgensteinians, a new account of the meaningfulness of Christian language is proposed. Moore uses this to develop a regulative conception of realism according to which God's independent reality is shown principally in Christ and then through Christian practices and the lives of Christians.
