This monograph on John 9 makes extensive use of premodern Christian exegesis as a resource for New Testament studies. The study reframes the existing critique of the two-level reading of John 9 as allegory in terms of premodern exegetical practices. It offers a hermeneutical critique of the two-level reading strategy as a kind of figural exegesis, rather than historical reconstruction, through an extensive comparison with Augustine´s interpretation of John 9. A review of several premodern Christian readings of John 9 suggests an alternative way of understanding this account in terms of Greco-Roman rhetoric. John 9 resembles the rhetorical argumentation associated with chreia elaboration and the complete argument to display Jesus´ identity as the Light of the World. This analysis illustrates the inseparability of form and content, rhetoric and theology, in the Fourth Gospel.
