On Ecclesiastical Theology: περὶ τῆς ἐκκλησιαστικῆς θεολογίας

by Eusebius of Caesarea

On Ecclesiastical Theology offers a rare glimpse into the foundational theological conflicts that shaped the early church’s understanding of God, the Logos, and Christ’s divine nature. Written during a time of intense doctrinal struggle, Eusebius provides a systematic defense of Nicene orthodoxy, engaging with alternative teachings and heresies that threatened the unity of Christian belief.
