Pass it on
Tacitus called Christianity a "mischievous superstition." Josephus was a Jewish general who served Rome. Pliny the Younger was annoyed by their stubbornness. None of them were converts. All of them confirm the same framework.
If the only sources for Jesus’ life were Christian, skeptics would have a point. But they are not. The Roman historian Tacitus, writing around 116 AD, confirms that "Christus" was executed by Pontius Pilate during the reign of Tiberius; and he does so with undisguised contempt, calling Christianity a "mischievous superstition" that spread from Judea to Rome. He was not trying to help the Christian case. He was recording facts for a history of Rome. And the facts he recorded align with the Gospel accounts on the essential points: a man named Christ was executed by Pilate, and his followers would not stop talking about it.
Josephus, a Jewish historian writing for a Roman audience, mentions Jesus twice; once in a passage that was likely edited by later Christians, and once in a passage that no serious scholar believes was interpolated, referring to "James, the brother of Jesus who was called Christ." Again: not a Christian source. Not trying to validate the faith. Just recording facts. And the facts confirm that Jesus existed, that He had a brother named James, that He was known as "the Christ," and that His movement continued after His death.
Pliny the Younger, a Roman governor writing to Emperor Trajan around 112 AD, describes Christians as people who "sing hymns to Christ as to a god" and who "bind themselves by oath not to commit fraud, theft, or adultery." He was asking for advice on how to prosecute them. He was not composing a testimony. And yet his letter confirms that within eighty years of the crucifixion, Christians in Asia Minor were worshiping Jesus as divine; a claim that would have been nonsensical if Jesus had been a myth or a failed revolutionary whose followers quietly dispersed after His death.
Hostile witnesses are more valuable than friendly ones. They have no motive to help your case. When they confirm your facts anyway, it is because the facts left them no choice.
These sources do not prove the resurrection. They were never intended to. What they prove is that the basic framework of the Gospel accounts; a historical Jesus executed under Pilate, whose followers worshiped Him as divine and spread His movement across the empire; is not a later legend. It was the established account within living memory of the events. The hostile witnesses confirm the framework. The question is what happened inside the framework. And for that, we need to look at the evidence more closely.
