This book attempts to investigate two strands in a single work: 'apocalyptic Paul' and 'intertextuality'. First, what does 'apocalyptic Paul' mean? Is it synonymous to eschatology as a theological notion, or the end-time mystery? Many seminal works have delved into the intriguing yet unorganized notion of the 'apocalyptic'. Instead of attempting to provide a universal definition of the 'apocalyptic', the author presents his understanding of the phenomenon, particularly in the cultural realm. The author contends that 'apocalyptic' is neither all about the end-time event nor merely a literary genre, but an interpretive lens to understand the world and social phenomena--one that is shaped and developed through culture and society. Accordingly, the term 'apocalyptic Paul' implies how Paul views and understands the world, history, and supernatural phenomena through interaction with his cultural texts and context. Second, the author also suggests that 'intertextuality' is not only about comparative literature study. Rather, intertextuality refers to cultural semiotics: a sign system to deliver the meaning of text. Based on this notion of intertextuality, the author interprets how Paul envisages multiple phenomena (heavenly ascent, resurrection, afterlife, the origins of sin, and two ages) within his cultural context.
