Eusebius’s “Fall Narrative” in Demonstratio Evangelica 4.6–10: Demonic Removal of the National Angelic Boundaries and the Watchers Tradition

Eusebius’s protological “fall narrative” in Demonstratio Evangelica 4.6–10 provides important context for understanding his theology of Christ as cosmic mediator. Eusebius uses Isa 10.13–14 to describe how God’s chief demonic antagonist disrupted the divinely sanctioned cosmic order of national patron angels (Deut 32.8–9), thereby corrupting the human race. Uniquely developing Origen’s account, Eusebius furnishes this theological history with motifs from a strand of the Watchers tradition that assigned a positive guardianship role to the Watchers before their rebellion. The Logos becomes incarnate and issues forth his divine instruction as an immediate response to this cosmic plight.
