Public theology has emerged in the twentieth and twenty-first centuries as theologians have increasingly entered the public square to engage complex issues. This 'Companion to Public Theology' brings a much-needed resource to this relatively new field. The essays contained here bring a robust and relevant faith perspective to a wide range of issues as well as foundational biblical and theological perspectives which equip theologians to enter into public dialogue. Public theology has never been more needed in public discourse, whether local or global. In conversation across disciplines its contribution to the construction of just policies is apparent in this volume, as scholars examine the areas of political, social and economic spheres as well as issues of ethics and civil societies, and draw on contexts from six continents.
