A Dissertation on the Books of Origen against Celsus

This thoughtful dissertation opens by introducing the clash between the fifth‑century critic Celsus and the early‑Christian scholar Origen, whose extensive reply was crafted at the request of Ambrose. The author sets the stage with a clear picture of Celsus’s hostile stance toward Christianity and Origen’s methodical, though sometimes unwieldy, defense, highlighting the historical significance of both works and their lasting influence on theological debate.

Focusing first on the Jewish foundations of the Christian faith, the essay examines Celsus’s attacks on the antiquity and reliability of Moses’s writings, then presents Origen’s counter‑arguments that draw on external sources such as Josephus and Tatian. By reorganizing the tangled exchange into a more coherent format, the author aims to make the ancient arguments accessible, showing how each side marshals evidence to support its view of truth.

Through careful analysis and clear exposition, listeners are invited to explore the early apologetic tradition and see how these foundational debates continue to shape discussions of faith, history, and reason.
