The Bible underneath it
Did Jesus Exist?
The calendar does not prove he did. The missing eyewitness does not prove he did not. What the evidence actually supports.
The argument
Two arguments about Jesus come up constantly. One says we count our years from his birth, so he must have been real. The other says no one who ever saw him wrote anything down, so he probably never existed.
Both arguments fail, for the same reason: each one claims more than its evidence can carry. What the evidence does support is narrower than either side wants. A Jewish preacher named Jesus almost certainly lived and was crucified. Nothing about that tells you whether he rose.
1. The calendar proves a belief, not a person
The year numbers we use were worked out around AD 525 by a monk named Dionysius Exiguus, who was building tables to calculate the date of Easter. He chose to count years from what he reckoned was the year of Jesus’s incarnation (his birth, or by some readings his conception). That was about five hundred years after the fact.
A calendar shows what the people who made it believed. Look at the rest of ours.
| Name | Named after | Do we think this god exists? |
|---|---|---|
| Thursday | Thor, the Norse thunder god | No |
| Saturday | Saturn, a Roman god | No |
| January | Janus, the Roman god of doorways | No |
| March | Mars, the Roman god of war | No |
| AD 2026 | Jesus, “the year of our Lord” | The calendar cannot say |
And the calendar does not even get his birth year right. Matthew 2 puts Jesus’s birth under King Herod, and most historians date Herod’s death to 4 BC. If Matthew is right, Jesus was born no later than 4 BC, four years “before Christ,” so by Matthew’s own account the calendar is off.
A calendar records what people believed when they made it. Thursday does not prove Thor.
2. The strongest point against him, stated fairly
Here is the mythicist case at its best. No surviving text can be shown to come from anyone who met Jesus during his lifetime. The Gospels were written decades later by authors who do not sign their names. Only John’s Gospel says an eyewitness stands behind it (John 19:35 and 21:24), and most scholars doubt that claim. The Roman writers who mention him were born after he died.
All of that is true. The question is what it proves.
Almost nothing survives that was written by or about ordinary rural Galileans of his time. Jesus was a rural preacher with no money, no office, and no army, executed as a troublemaker in a small province. People like him almost never left a record of any kind. If “no eyewitness account” means “did not exist,” nearly the whole population of the ancient world disappears with him.
He is also not the only famous teacher who left nothing in his own hand. Socrates wrote nothing. Almost everything we know about him comes from people who knew or followed him, mostly Plato and Xenophon, plus a comedy by Aristophanes, and they do not always agree. Historians argue about what Socrates taught, not about whether he lived.
So historians ask a different question: how close do the sources get, and do they come from people who had no reason to invent him?
3. Paul met his brother
Paul’s letters are among the earliest Christian writings that survive, written roughly AD 50 to 60, about twenty years after the crucifixion. Galatians is one of the letters nearly every scholar, believing or not, agrees Paul really wrote. In it, Paul describes his first trip to Jerusalem after he converted.
Galatians 1:18–19, King James Version
Then after three years I went up to Jerusalem to see Peter, and abode with him fifteen days. But other of the apostles saw I none, save James the Lord’s brother.
In plain English: Paul stayed two weeks with Peter, and met James, the brother of Jesus. Paul is a firsthand witness to the people who knew Jesus best.
Read Galatians 1A man invented as a story does not usually have a brother you can go visit in Jerusalem.
4. Two historians outside the Bible
Josephus, Jewish historian, Antiquities of the Jews 20.9.1
Written around AD 93
What it establishes: Josephus mentions Jesus in passing, to identify James, who was stoned to death around AD 62. A Christian inserting Jesus would be unlikely to do it this briefly. Scholars widely accept this line as Josephus’s own.
Read Book 20Tacitus, Roman historian, Annals 15.44
Written around AD 116
What it establishes: A Roman senator describing the founder of a group he despised, in the same passage that calls their faith “a most mischievous superstition,” as a man executed by a Roman governor.
Read Annals 15.44Josephus has a second, longer passage about Jesus in Book 18, called the Testimonium Flavianum, which calls him the Messiah and says he rose. Most scholars agree Christians added to it, because a Jewish writer would not have said those things. But the majority view is that later Christians edited a real passage, not that someone made it up whole. The theory that Eusebius forged it is a minority position. And the James line in Book 20, quoted above, is a separate passage that stands on its own.
The mythicist argument dismisses each of these writers because they were born too late. But that is how ancient history works for nearly everyone. Historians do not need an eyewitness. They need sources close in time, independent of each other, with no reason to make the thing up. Paul, Josephus, and Tacitus are three different kinds of writer, a Christian, a Jew, and a Roman who disliked Christians, and all three treat Jesus as a real man. Paul and Tacitus both say he was executed.
5. What a real Jesus does and does not give you
This is why the consensus is not a win for the Church, or for anyone’s church. Bart Ehrman, an agnostic and one of the best-known Bible scholars alive, wrote a whole book against the mythicists. His conclusion: “Whether we like it or not, Jesus certainly existed.” He does not believe Jesus rose.
This is an old position, not a new one. In 1820 Thomas Jefferson took a razor to several copies of the New Testament and pasted together the teachings of Jesus with every miracle cut out, including the resurrection. He called it The Life and Morals of Jesus of Nazareth, and the Smithsonian has held it since 1895. Jefferson kept the man and the morals, and cut the rest.
- A Jewish preacher named Jesus lived in Galilee
- He had a brother named James
- He was crucified under Pontius Pilate
- His followers came to believe he had risen
- That he was born of a virgin
- That he worked miracles
- That he rose from the dead
- That he appeared in the Americas, or in a grove in New York
Existing is the easy part. A real crucifixion is evidence for a man. It is not evidence for a resurrection.
What is true on the other side
- There really is no eyewitness account. Mythicists are right about that, and Christians who call the Gospels eyewitness testimony are claiming more than most scholars, including many believing ones, accept.
- A few credentialed scholars are mythicists. Richard Carrier and Robert M. Price, both with doctorates in relevant fields, have argued it in print. It is not a position only amateurs hold. It is a position almost no working historian of the period finds convincing.
- The Book 18 passage really was tampered with. Anyone who quotes it in full as proof is quoting Christian additions.
The common rebuttals
“Historians mentioned Hercules too. Does that mean Hercules was real?”
Ancient writers mention Hercules as a hero of myth, a son of Zeus, never tied to a datable ruler, governor, or event. Tacitus mentions Jesus as a man executed under a named governor, during a named emperor’s reign. Paul names his brother. Those are not the same kind of mention.
“If you’ve left the Church, why defend the idea that Jesus existed at all?”
Because the reason to leave a claim is that the evidence does not support it. The same rule applies on the way out. A person who rejects the First Vision because the record does not hold up, and then accepts a claim the record also does not support, has not changed how they decide what is true. They have only changed sides.
“The Gospels are just stories, so the whole thing is a story.”
The Gospels contain a great deal historians doubt, from the census to the miracles. But a story built around a real person is still built around a real person. Legends grow around real people all the time. There is no evidence George Washington chopped down a cherry tree. His biographer Mason Weems added that story in 1806, and there was still a George Washington.
What this means
The calendar argument and the missing-eyewitness argument make the same mistake from opposite sides. One treats a calendar as proof Jesus existed. The other treats a missing eyewitness as proof he did not. Neither is how anyone checks anything else.
Leaving a belief because the evidence does not hold it up only means something if you hold your new beliefs to the same standard.
The historical Jesus is a real man about whom very little can be known. The rest of the story, the virgin birth, the miracles, the empty tomb, is where the evidence actually runs out, and that is the next page.
