To what extent and to what purposes did John Chrysostom engage previous models of Biblical exegesis? In this systematic study of his Homilies on Genesis, new light is shed on the precision of his adaption of works by Basil, Origen, Eusebius of Emesa, and Eusebius of Caesarea, findings set against a wider ‘web’ of parallels with various other exegetes (e.g. Ephrem, Diodore, Didymus). The cumulative picture is a network of shared knowledge across geographical and ecclesial boundaries which served as creative cache for Chrysostom’s discourses. With the metaphors of textual obscurity and word-depth, he prioritized name and word interpretations as a means of producing multiple layers of ethical evaluation.
