This provocative collection of papers from an international array of theologians explores the Christian doctrine of the Trinity in the context of twentieth-century cultural and religious pluralism. How should Christians think about their faith in relation to other faiths and in relation to culture in general? Can the Trinity fit into a global religion? These essays - originally presented at the Fifth Edinburgh Dogmatic Conference - show how a full-orbed Trinitarian doctrine, with a proper emphasis on both the One and the Three, provides the necessary resources for successfully addressing the problems and the possibilities of contemporary pluralism.
