Did Jesus really exist?

The evidence

Tacitus, a Roman historian

Writing around AD 116 or 117, Tacitus explained who the Christians were:² “Christus, from whom the name had its origin, suffered the extreme penalty during the reign of Tiberius at the hands of one of our procurators, Pontius Pilatus.”³

Tacitus had no sympathy for Christians. In the same passage he calls them “a class hated for their abominations.”³ He still reports Jesus’s execution as a plain fact. Tacitus on Jesus looks at the passage closely.

Josephus, a Jewish historian

Josephus mentions Jesus twice in his Antiquities of the Jews. The shorter mention is about the stoning of “the brother of Jesus, who was called Christ, whose name was James.”⁴ Few scholars have ever doubted it. The Biblical Archaeology Society’s survey of the evidence says “the huge majority accepts it as genuine.”²

The longer passage, called the Testimonium Flavianum, describes Jesus as “a wise man” and “a doer of wonderful works.”⁵ Most scholars think Josephus wrote a version of it and that a Christian copyist later added lines, such as “He was [the] Christ.”² Others think too much was changed to recover what Josephus wrote.⁶

Pliny the Younger, a Roman governor

Around AD 110 to 113, Pliny wrote to the emperor Trajan asking how to handle Christians in his province. He reported that they “met on a stated day before it was light, and addressed a form of prayer to Christ, as to a divinity.”⁷ That shows what Christians believed about Jesus within a century of his death.

What historians conclude

A University of Cambridge summary puts it this way: “virtually every ancient historian and biblical scholar regards Jesus of Nazareth as a historical figure.”⁸ Simon Gathercole, a Cambridge New Testament scholar, writes that “we know of no one in the ancient world who questioned whether Jesus lived.”⁹

The strongest objection

None of these writers knew Jesus. The earliest of them wrote decades after he died, and they may only be repeating what Christians told them. As Ehrman himself notes, “Jesus is not mentioned in any Roman sources of his day.”¹

Some scholars press that point. E. P. Sanders, writing in Encyclopaedia Britannica, says that what Tacitus and Suetonius knew “was dependent on familiarity with early Christianity and does not provide independent evidence about Jesus.”⁶

Response

Josephus is the hardest source to explain away. He was a Jewish historian, not a Christian, and his note about James, “the brother of Jesus, who was called Christ,” is accepted as genuine by the “huge majority” of scholars.²⁴ It names Jesus in passing, to identify which James was meant.

Tacitus disliked Christians and had no reason to invent a founder for them. He reports the execution under Pilate as settled fact.³

And the doubt itself is modern. Gathercole’s point stands: no one in the ancient world, friend or enemy, questioned that Jesus lived.⁹ Today the scholars who argue he never existed are a handful. Richard Carrier, one of them, counts “at least six well-qualified experts” who share his doubt.¹⁰ Ehrman calls their view “unconvincing to 99.99 percent of the real experts.”¹

What these sources don’t show

They show that Jesus lived, taught, gathered followers, and was executed under Pilate. They don’t prove his miracles or his resurrection. The lines in Josephus that say so are exactly the ones most scholars think a Christian copyist added.² Pliny shows what Christians believed, which is a different thing from proof that they were right.²

The evidence for the resurrection is a separate question. Did Jesus rise from the dead? takes it up.

Questions people ask

Is there evidence outside the Bible that Jesus was crucified?

Yes. Tacitus says Christus “suffered the extreme penalty” under Pontius Pilate.³ He doesn’t name the method, but he confirms the execution and who ordered it. The Babylonian Talmud also says Jesus was “hanged” on the eve of Passover, though scholars doubt that tradition is independent of the Gospels.²

Did Josephus believe Jesus was the Messiah?

Probably not. The standard text says “He was [the] Christ,” but most scholars think a Christian copyist added that line.² An Arabic version of the passage, published by Shlomo Pines in 1971, reads “he was perhaps the Messiah,” though scholars debate how close that version is to what Josephus wrote.² Elsewhere Josephus calls him “Jesus, who was called Christ,” which sounds like a report of what others said.⁴

Did Suetonius mention Jesus?

Maybe. The Roman biographer Suetonius wrote that the emperor Claudius expelled Jews from Rome because they “constantly made disturbances at the instigation of Chrestus.”¹¹ Many scholars think “Chrestus” is a misspelling of Christus, but it isn’t certain.²

What percent of historians believe Jesus was real?

There’s no formal count. Scholars on every side describe near-total agreement, from Cambridge’s “virtually every ancient historian” to Ehrman’s “99.99 percent.”¹⁸

• Did Jesus Exist? by Bart Ehrman: an agnostic historian makes the case that Jesus lived. It’s under “Know the other side” on the Shelf.
