What did non-Christian authors say about Jesus?
As far as we know, the first author outside the church to mention Jesus is the Jewish historian Flavius Josephus, who wrote a history of Judaism around AD93. He has two references to Jesus. One of these is controversial because it is thought to be corrupted by Christian scribes (probably turning Josephus’s negative account into a more positive one), but the other is not suspicious – a reference to James, the brother of “Jesus, the so-called Christ”.
About 20 years after Josephus we have the Roman politicians Pliny and Tacitus, who held some of the highest offices of state at the beginning of the second century AD. From Tacitus we learn that Jesus was executed while Pontius Pilate was the Roman prefect in charge of Judaea (AD26-36) and Tiberius was emperor (AD14-37) – reports that fit with the timeframe of the gospels. Pliny contributes the information that, where he was governor in northern Turkey, Christians worshipped Christ as a god. Neither of them liked Christians – Pliny writes of their “pig-headed obstinacy” and Tacitus calls their religion a destructive superstition.
Did ancient writers discuss the existence of Jesus?
Strikingly, there was never any debate in the ancient world about whether Jesus of Nazareth was a historical figure. In the earliest literature of the Jewish Rabbis, Jesus was denounced as the illegitimate child of Mary and a sorcerer. Among pagans, the satirist Lucian and philosopher Celsus dismissed Jesus as a scoundrel, but we know of no one in the ancient world who questioned whether Jesus lived.
