# Jesus Family Tomb

# The Battle of the "Jesus Family Tomb"

**On the last Sunday**in February or 2007, I got an email from a friend of mine with a provocative subject line:

"Don't Go To Church Today"

**I opened the email**and found a link to a web page announcing the discovery of the tomb of Jesus. Complete with bone/boxes with the names of Jesus, his mother Mary, his brother Yosi, his disciple Matthew, his wife Mary Magdalene, and his son Judah.

**At first I thought it was a joke**. Then I saw that these people were serious.

**They were due to release a documentary**on the Discovery channel, and the producer//Simcha Jacobovici//was an Emmy award winning journalist. He had backing from James Cameron, director of the movie,

**The Titanic**.

**Furthermore, they had a well/known Biblical scholar**with a strong archaeological background on their team//James Tabor//chairman of the Department of Religious Studies at the University of North Carolina.

**And they had a statistician**on board, Andrey Feuerverger, from the University of Toronto. His calculations showed very high odds that this was the authentic tomb of Jesus. They were quoting odds of 600 to 1.

**At that point**, I began wondering if maybe I shouldn't skip church after all.

**Because if this tomb was legit**, then Jesus didn't rise from the dead and Christianity was a crock.

## But Was It Legit?

**I have many friends**who simply assumed right away that the whole thing was a scam. Yet another try by those pesky "secular humanists" to disprove Christianity. For these friends, that was the only possible conclusion. For them, Jesus obviously rose from the dead, and therefore this tomb must be a fake.

**That's not how my brain works**. In Myers/Briggs terminology, I'm an INTP, and that means I'm always open to new evidence.

**I decided**that I had to look into this. Evidence is evidence, and you don't ignore it just because it screws up your current theological position. You can change your theology. I've done that often enough in my life.

**The Jesus Family Tomb**might mean a massive change in theology for a lot of people.

**I read all the info**I could find online about this Jesus Family Tomb, but it was pretty thin. There was a documentary due to come out a week later//the next Sunday night//but I didn't figure a documentary would go very deep.

**Fortunately**, the producer of the documentary had a book coming out on the subject in just a few days//

**The Jesus Family Tomb**, by Simcha Jacobovici and Charles Pellegrino, with a foreword by James Cameron.

**On Wednesday morning**, the day the book came out, I bought a copy at my local Barnes & Noble. I went home and started reading.

## The Evidence

**As I read the book**, I quickly saw two things:

- Everything hinged on the math.
- The math as explained in the book was wrong.

**The book didn't actually explain**Andrey Feuerverger's calculations. Instead, it gave a hokey, lame, non/mathematician's version of the math. It was wrong, but it was unclear just how wrong. Sometimes you can do the math wrong and still come to a correct conclusion.

**I couldn't tell**if the errors in the math would change the result.

**I knew it was possible**that the book had done the math wrong and yet still got the right answer. It was possible that the Jesus Family Tomb was legit. It was possible that doing the math right would show that the tomb was likely to be the final resting place of Jesus of Nazareth.

**By Thursday night**, I had finished the book and now I had a clear picture of all the information. I knew I had to get to the bottom of this. The math was clearly wrong, but I felt confident I could redo it correctly. I'd worked on this kind of problem before when I looked into the alleged Bible code back in 1998.

## Doing the Math

**So I opened up a spreadsheet**and started entering numbers. I didn't have all the data I needed, but I did have another book about the famous James ossuary that filled in enough of the missing pieces to get a preliminary result.

**An hour later**, I had my answer.

**Not only was the math**in the book wrong, it was wildly wrong.

**The odds**were not 600 to 1 in favor of this being the tomb of Jesus.

**The simplest math**calculation showed that the odds were more than 10 to 1 AGAINST this being the tomb of Jesus. And if you added in one historical fact, the odds got even longer.

**For all I knew**, at that moment I was the only person in the world who had done the math even approximately right. Most mathematicians don't have a high interest in first/century Jewish archaeology as it relates to the New Testament. And most archaeologists and New Testament scholars don't know much about math.

**Whereas I know quite**a lot about both. I have a Ph.D. in theoretical physics from UC Berkeley and had some experience in tracking down wrong probability calculations. And I also had done more than twenty years of research for my series of historical novels set in first/century Jerusalem.

**I had exactly**the weird and diverse background needed for this mad science problem.

**That's when**I decided to go public.

## Getting The Word Out

**One of the first things**I did was to email a guy I knew, Mike Heiser, who has a Ph.D. in Biblical Hebrew from the University of Wisconsin. I had met him online years earlier when we both were writing books about the alleged Bible code. I didn't believe in the Bible code on scientific grounds. Mike didn't believe in it on linguistic grounds.

**I told Mike**what I'd done with my calculations on the Jesus Family Tomb and he got extremely excited. Turned out he had been interested in this tomb for some time (long before the announcement by the documentary maker). He already knew a lot about the archaeology of the tomb and was writing an article about it.

**Mike encouraged me**to get the word out. I spent a good part of Friday and Saturday writing up a preliminary report on my web site in an article titled

**Statistics And The Jesus Family Tomb**.

**By Sunday**, I had notified a bunch of my writer friends about this article. Like good writers everywhere, they blogged about it and linked to my site. And I started seeing traffic to the article.

**Sunday night, the infamous documentary**by Simcha Jacobovici finally aired. A lot of scholars in the New Testament Studies and archaeological worlds watched the documentary and blogged about it. Virtually all of them panned it. For various reasons, they weren't buying the claim that this was the tomb of Jesus of Nazareth.

**A lot of their blogs**questioned the math. But they weren't thinking like mathematicians. They felt in their gut that the math was wrong, but they couldn't explain why.

**I left comments**on a few of their blogs to say that I had worked out the math, and I gave a link back to my web site.

## The Aftermath of the Math

**Within days**, the bloggers had read my article and started blogging about me and my work. The consensus was that I'd hit the nail on the head. My own opinion was that I'd made a nice start, but it wasn't the final word. This first probability estimate was very simple and there was a lot of room for refinement.

**One of the bloggers**was Jay Cost, a political science Ph.D. student at the University of Chicago. Jay was heavily into probability as it applies to social sciences. He emailed me to ask why I hadn't used Bayes' Theorem in my article. He gave me a link to his blog article.

**I hadn't really thought**about Bayes' Theorem, but after reading Jay's article, he and I teamed up to look at the whole thing more carefully. Jay also put me in touch with James Tabor, the one academic who was publicly saying that he thought the tomb was authentic.

**For the next few weeks**, I spent a lot of time discussing the tomb with James Tabor. He had read my article and could see right away that I'm no fundie and that I was seriously open to all data. So he gave me any info I asked for.

**James and I**were on opposite sides of the argument, but we had a mutual respect from the get/go. Whoever invented the buzzword "thinking outside the box" might have been talking about James Tabor. He has a lot of unconventional ideas, and I find that interesting. Of course, unconventional ideas usually turn out to be wrong. That's okay, because when a way/out idea turns out to be right, you get a revolution. So I like James and enjoy hearing his ideas. Like most people in the religion department, he's not strong in math. Like most math geeks, I'm not strong in Hebrew or Greek. James formed an e/mail group with several interested scholars and stats guys, including Jay and me. We spent several weeks in intense discussion.

**At the end of that time**, Jay Cost and I jointly wrote an article,

**Bayes' Theorem And The Jesus Family Tomb**. We looked at a variety of different assumptions to see if any of them could lead to good odds for the authenticity of the tomb. We couldn't find any. In many cases, the odds got extremely long against the tomb.

**During all this time**, I was quite interested to hear the opinion of Andrey Feuerverger, the statistician from the University of Toronto hired by the documentary makers. The problem was that Simcha Jacobovici in his book and in his documentary never really explained what Dr. Feuerverger had actually done.

**I emailed Professor Feuerverger**, asking if I could see a preprint of his results. (When I was a grad student in theoretical physics, everybody sent out preprints long before the official publication of their articles in the academic journals.) Feuerverger emailed me back to apologize that he couldn't send me anything until his paper was published in the journal he'd submitted it to.

**I thought**that was that, but it wasn't.

Andrey Feuerverger's Work At Last

**Months passed**, and in October of 2007, Feuerverger's editor at

**The**

**Annals Of Applied Statistics**sent me an urgent email asking me to serve as a referee on Feuerverger's paper, which had been submitted months earlier.

**I agreed**to referee the article and immediately received a copy of Feuerverger's paper. The journal also offered me the chance to publish a response to Feuerverger's article. And they also offered me space on their web site to include any amount of other electronic material for download.

**I read through**Feuerverger's article and enjoyed reading it very much. It was clear that the documentary producer, Simcha Jacobovici, simply hadn't understood any of the math Feuerverger had done.

**This really irked me.**Feuerverger had taken a lot of heat from the scientific community when the whole foofah broke into the news. People had said a lot of things about him, based on what they thought he had done. I had said some things about his calculations. But what we all thought Feuerverger had done had been filtered through Simcha Jacobovici. So we got a very mistaken picture of his calculations.

**Feuerverger's math was fine**. It was very much more sophisticated than the math shown in Jacobovici's documentary and book. Feuerverger used a different approach in his analysis than I had used, but he did a very careful job analyzing the information that he was given.

**And that was the problem**. Some key pieces of information that Feuerverger was given were wrong. He couldn't have known that without having a lot more background in archaeology than most statisticians have.

**It looked to me**like a classic failure to communicate.

**I spent quite a lot of time**writing up a response to Feuerverger's paper. Part of this was for Feuerverger's eyes only, explaining why certain ideas he'd been given by Jacobovici were wrong. Part of my time went into a ten page response article for

**The**

**Annals Of Applied Statistics**, explaining the six faulty assumptions that his calculations were based on.

**I also took the opportunity**to do a new and more sophisticated set of Bayesian probability calculations analyzing the tomb in even more detail than before. Here, I added in some new ideas that I'd come up with after reading an article by Kevin Kilty and Mark Elliot // one of the very few articles anywhere that have argued that the Jesus Family Tomb hypothesis might be correct. (Working with two different sets of assumptions, they came up with odds of either 6% or 48% that the tomb is authentic.)

**I've summarized my final conclusions**in an article here on my site, Analysis of Andrey Feuerverger's Article on The Jesus Family Tomb.

## Did Jesus Rise From the Dead?

**I often hear from Christians**asking why I don't get a probability of zero. After all, they argue, Jesus rose from the dead and therefore the tomb can't be authentic. End of discussion // for them, anyway.

**My response**is that all probability calculations depend on your assumptions.

**If you take as an axiom**that Jesus rose from the dead, then the tomb can't be authentic. This is obvious, and nobody argues with this. But of course, not everybody accepts this claim as axiom, so this is a pretty weak result. (My own position is that the alleged resurrection of Jesus has to be treated as a hypothesis // a possibly true statement that must be tested by the known evidence.)

**The much harder question**is what happens if you take as an axiom that Jesus never rose from the dead? What if you assume that his mortal remains are somewhere in Jerusalem? In that case, what is the probability that the tomb in Talpiot that Simcha Jacobivici calls the "Jesus Family Tomb" was in fact his final resting place?

**That is the probability problem**we are all trying to solve. It's a hard problem, because there are several other assumptions you have to make in order to do a calculation. For example, precisely who would you expect to be buried in a "Jesus family tomb" if it existed? His mother? Which of his brothers? Who else? What are the legitimate spellings for these people? Before you do the calculation, you have to decide on each of these questions.

**Nobody knows**exactly who should be in a "Jesus family tomb." Nobody knows what the most probable spelling for the tomb occupants should be. You can study each set of assumptions. Most plausible sets lead to probabilities below about 2%. It is possible to make a set of assumptions that bump the probability up a bit higher than that, but my view is that it's hard to justify any of these. I can't see a way to legitimately get up above 6%, but even getting that high requires stretching. Assumptions that seem reasonable to me lead to a probability estimate of about 2%. If you push these to be a bit more conservative, you can get the probability very much lower than 2%.

**None of this should be considered a "proof"**that Jesus rose from the dead. (This ought to go without saying, but whenever something should go without saying, I've invariably found that it's necessary to say it.) With the historical data we have, it is impossible to prove that Jesus rose from the dead. It is also impossible to prove that he didn't, unless you make a metaphysical assumption along the lines of "God does not exist" or "It is not possible for God to raise anyone from the dead."

**The correct statement**is that the Jesus Family Tomb does not give us strong evidence that Jesus did not rise from the dead. The actual evidentiary worth of the Jesus Family Tomb is very low.

**Let's be clear**. It could have been different. If the tomb had presented different evidence, it could have made a very strong case against the alleged resurrection of Jesus.

**But it didn't**.

## The Story Isn't Over

**I should also be clear**that if new evidence comes out, it could change my opinion. In particular, if it turned out that the famous James ossuary were authentic and had been included in the Talpiot tomb, then that would have a very large effect on my probability estimate. I mention this because Simcha Jacobovici and James Tabor have argued that the James ossuary may have originally been in the Talpiot tomb.

**The James ossuary**bore the inscription "James son of Joseph brother of Jesus." The owner of the ossuary, Oded Golan, was eventually arrested on forgery charges. The forgery trial dragged on for years and finally ended in a verdict of not guilty. But opinion among scholars seems to be split on which parts of the inscription, if any, are authentic. I'm open to the authenticity of this inscription, but I can see no reason to think the ossuary was ever part of the Talpiot tomb.

**In my view**, most academics have been too quick to dismiss the Jesus Family Tomb. A group of them eventually made a joint public statement that the odds of authenticity for the tomb are "virtually nil." I believe the tomb is unlikely to be authentic, but I don't agree that the odds are "virtually nil."

**To me**, "virtually nil" means odds that are vanishingly small // less than one in a billion, say. I don't see that. I'd put the odds at less than 1 in 50. The case is not closed. Maybe it never will be.
