Can Pauline soteriology be categorized as a form of deification? This book attempts to answer this question by keen attention to the Greco-Roman world. It provides the first full-scale history of research on the topic. It is also the first work to fully treat the basic historical questions relating to deification. Namely, what is deity in the Greco-Roman world? What are the types of deification in the Greco-Roman world? Are there Jewish antecedents to deification? Does Paul consider Christ to be a divine being? If so, according to what logic? How is Pauline deification possible in light of ancient Jewish "monotheism"? How is deification possible with a strong notion of creation? Although a rigorously historical study, no attempt is made to avoid theological issues in their historical context. Deification, it is argued, provides a new historical category of perception with which to deepen our knowledge of the Apostle's religious thought in its own time. This book is intended for an academic audience. The range of topics discussed here should interest a wide-array of scholars in the fields of Hebrew Bible, New Testament, Classics, and Patristics.
