The first church historian
Eusebius was bishop of Caesarea in Palestine and is the single most important source for the history of the church's first three centuries. His Ecclesiastical History preserves letters, martyr accounts, episcopal successions and quotations from second-century writers whose works are otherwise entirely lost — including Papias, Hegesippus and large portions of Origen.
He wrote as a participant, not a distant observer. He lived through the Diocletian persecution, saw friends executed, and then lived to see Constantine legalise the faith. That proximity is both his value and his limitation.
Read him as you would read any ancient historian: as a witness with commitments. Eusebius is demonstrably reliable when he quotes documents, and demonstrably partisan when he assesses Constantine. Modern scholarship uses him constantly while cross-checking him constantly.
House churches before dawn, shared meals, baptism in running water, care for widows and abandoned babies — what ordinary Christian life looked like in the first three centuries, and why Rome called them atheists.
From twelve frightened men to the official faith of the empire in three centuries — the roads, the martyrs, the plagues, the strategy and the emperors that made it happen.
The first Christian emperor is blamed for inventing the deity of Jesus, choosing the Bible and replacing the Sabbath. What Constantine actually did, what he did not do, and what imperial favour gave and cost the church.
Papias, Irenaeus and the Muratorian fragment; the anonymity question; pre-70 and post-70 dating; Markan priority, Q and the Farrer hypothesis; the beloved disciple; and Bauckham's eyewitness thesis — with the sceptical case stated fairly.
His failure and restoration, his ministry in Rome, his death under Nero, and what the historical record adds beyond the book of Acts.
From persecutor to apostle: the Damascus road, three missionary journeys, thirteen letters, the shipwrecks and floggings, and his execution in Rome.
The evidence for Thomas's mission to south India, the ancient Mar Thoma community that traces to him, and why "Doubting Thomas" is the wrong name for him.
From son of thunder to apostle of love: his Gospel, his letters, his exile on Patmos, and the only apostle who appears to have died of old age.
A source-by-source account of where each of the twelve went and how each died, distinguishing what is well attested from what is late tradition.
