In February 2014 the Association of Christian Philosophers in Catholic Schools of Theology in German Speaking Countries dedicated its biannual conference to philosophical theology, which has become a recently vibrant and suspenseful area of research and interest. The specific contributions of various experts, who participated in the conference, revolved around the problems of standard and non-standard concepts of God. The main purpose of the conference was to bridge several gaps: between philosophy and systematic the- ology, between continental and analytic traditions, between German and English speaking philosophers and their preferred traditions. The present volume is dedicated to the question whether or not the concept of a personal God faces serious challenges and whether these challenges also include a serious modification of classical theism. Along these lines the complicated relations between classical theism and personal theism as well as the chances for the development of non-standard conceptions of the divine are discussed and presented.
