In the age of the Theodosian dynasty and the establishment of Christianity as the only legitimate religion of the Roman Empire, few figures are more pivotal in the power politics of the Christian church than archbishop Theophilus of Alexandria (385-412). This work examines the involvement of archbishop Theophilus in the so-called First Origenist Controversy when the famed third-century Greek theologian Origen received, a century and a half after his death, a formalcondemnation for heresy. Modern scholars have been successful in removing the majority of the charges which Theophilus laid on Origen as not giving a fair representation of his thought. Yet no sufficient explanation has been offered as to why what to us appears as an obvious miscarriage of justicecame to be accepted, or why it was needed in the first place. Kratsu Banev offers a sustained argument for the value of a rhetorically informed methodology with which to analyse Theophilus anti-Origenist Festal Letters. He highlights that the wide circulation and overt rhetorical composition of these letters allow for a new reading of these key documents as a form of mass-media unique for its time. The discussion is built on a detailed examination of two key ingredients in the pastoralpolemic of the archbishop - masterly use of late-antique rhetorical conventions, and in-depth knowledge of monastic spirituality - both of which were vital for securing the eventual acceptance of Origens condemnation. Dr Banevs fresh approach reveals that Theophilus campaign formed part of a consistentpolicy aimed at harnessing the intellectual energy of the ascetic movement to serve the wider needs of the church.
