An important mark of a systematic theology is that it be distinct from the rest; owning one does not preclude the need for others. What distinguishes Pannenberg's (systematic theology, Univ. of Munich) is his insistent attention to "the truth of Christian doctrine." How to arrive at this truth and how it informs understanding of God and humanity is the subject of this first of three volumes. His argument is painstakingly arranged and rightfully builds on centuries of Christian discourse. At times Pannenberg seems to make divine truth contingent upon human understanding, which nearly undermines his case. Still, he is unapologetically straightforward where others might beg the question. Recommended for seminary libraries; university libraries should wait for all three volumes to assess need. Most public libraries will find scant call for this.
