This monograph on "John 9" makes extensive use of premodern Christian exegesis as a resource for New Testament studies. It draws on ancient Christian ways of reading Scripture in a 'more-than-literal' or 'figural' way to critique the modern trend to understand John's Gospel as recounting the history of the evangelist's community. This study also examines a variety of premodern interpretations of "John 9" for insight into the chapter's theological and rhetorical dimensions. Building upon the premoderns' observations, it argues that "John 9" resembles a mode of Greco-Roman rhetorical argumentation and expression to present Jesus as the Light of the World. This analysis illustrates the inseparability of form and content, rhetoric and theology, in the "Fourth Gospel".
