Common questions about Eusebius

Short answers, pulled from the story.

Who was Eusebius of Caesarea and what was his role in early Christianity?

Eusebius of Caesarea was a Greek Christian bishop and scholar born around the year 260 who saved the history of early Christianity from total oblivion. He served as a librarian of the faith and a historian who preserved fragments of texts that would otherwise have vanished forever. His work spanned the turbulent decades of the Roman Empire including the Great Persecution under Diocletian and the rise of the first Christian emperor Constantine.

What library did Eusebius inherit and what did it contain?

Eusebius inherited a library established by the wealthy deacon Pamphilus in Caesarea that rivaled the great centers of Alexandria and Antioch. This library contained biblical manuscripts including Origen's massive Hexapla and the original Aramaic version of the Gospel of Matthew. It also housed the works of Origen and served as a sanctuary for Christian learning during the persecutions.

When did Eusebius become the Bishop of Caesarea and what controversies did he face?

Eusebius succeeded Agapius as the Bishop of Caesarea in the year 313 following the Edict of Milan which granted religious tolerance to Christians. His tenure was marked by his involvement in the Arian controversy and his role in the condemnation and exile of Athanasius at the Council of Tyre in 335. These actions secured his favor with Emperor Constantine but alienated him from many orthodox Christians.

What is the Life of Constantine and why is it controversial?

The Life of Constantine is a eulogy written by Eusebius that recounts the vision Constantine experienced before the Battle of the Milvian Bridge in 312. It is controversial because historians criticize its rhetorical style and apparent bias in favor of the emperor while noting that the Arch of Constantine built in 315 makes no mention of the vision. The work remains invaluable for its inclusion of primary documents and eyewitness accounts that would otherwise be lost.

What major works did Eusebius create to structure the Bible and history?

Eusebius developed the Eusebian Canons a system of cross-references that allowed readers to easily compare the four Gospels and his Chronicle a universal history from the Creation to his own time. He also wrote the Onomasticon a geographical lexicon of places mentioned in the Bible and works on biblical criticism including the Demonstrations of the Gospel and the Preparation for the Gospel. These writings preserved the thoughts of Pyrrho Sanchuniathon and Euhemerus among others.

When is the feast day of Eusebius and where are his relics preserved?

Eusebius was venerated as a saint in the early church with his feast day celebrated on the 30th of May in the Syrian Martyrology of 411. His relics including a bone fragment are still preserved in the Shrine of All Saints in Morton Grove Illinois. He was honored in the Roman Catholic Church for centuries until his name was mistakenly replaced by that of Eusebius of Samosata during the time of Pope Gregory XIII.
