The History of the Church: Historia Ecclesiastica
Eusebius of Caesarea’s History of the Church (Historia Ecclesiastica) is the earliest surviving account of Christianity’s growth from a persecuted sect to an empire-wide faith. Written in the early fourth century, this monumental work draws from scripture, state records, personal letters, and now-lost sources to capture the church’s first three hundred years.

The Proof of the Gospel: Demonstratio Evangelica
The Proof of the Gospel (Demonstratio Evangelica) is Eusebius’s theological masterwork: a thorough and systematic presentation of Christianity as the fulfillment of both Jewish prophecy and Greek philosophical longing. Writing from his position as bishop of Caesarea, Eusebius argues that the life, death, and resurrection of Jesus were not an innovation, but the long-anticipated climax of divine revelation.
-
The Preparation for the Gospel: Praeperatio Evangelica
In this monumental early church apologetic, Eusebius systematically dismantles the contradictions and moral failings of Greco-Roman polytheism. Drawing deeply on the Hebrew Scriptures, he demonstrates how divine wisdom and providence have been unfolding throughout history to prepare humanity for the revelation of Jesus Christ. Rather than rejecting classical philosophy outright, Eusebius engages with it critically, highlighting its highest ideals as pointers toward the fullness of Christian truth. This work stands as a bridge between pagan philosophy and Christian theology, showing how early Christians used reason, history, and prophecy to defend and explain their faith.
