Pastor's
Page By Fr. George Welzbacher March 18, 2007 With respect to the Discovery Channel's pseudo-documentary "The Lost Tomb of Jesus" I should like to add a follow-up to the remarks I made in last week's Pastor's Page. In denying Christ's virginity and His bodily resurrection the team that produced the "documentary" relied heavily on the high degree of probability, as alleged by a mathematician from Toronto, that the names inscribed on the ossuaries (bone-boxes) designate the supposed "family" of Jesus and no other. Supported by a blackboard- filling cargo of equations, Professor Andrey Feuerverger was shown announcing his conclusion that the chance that these ossuaries belonged to a family other than the putative family of Jesus should be read as one in six hundred. Since the program's airing on March the fourth some prestigious mathematicians have publicly dismissed Professor Femerverger's calculations as an example of sloppy mathematics. One such mathematician, "The Numbers Guy" for the Wall Street Journal, Carl Bialik, whose column on mathematical questions appears in the Journal every two weeks, had this to say in the Journal's issue of March ninth. * * * * Questionable Odds Have Been Unearthed In the Lost Tomb. By Carl Bialik Until two weeks ago, University of Toronto statistician Andrey Feuerverger's body of research encompassed uncontroversial topics such as medical scanning and correcting for camera blurring. So he was unprepared for the reaction to his work for the Discovery Channel documentary "The Lost Tomb of Jesus," which aired on Sunday, March 4th. The tomb is a set of 10 limestone coffins, or ossuaries, found in Jersalem in 1980, bearing the names Yeshua bar Yosef (Jesus, son of Joseph), Maria (Mary), Matia (Matthew), Yose (a nickname for Joseph), Mariamene e Mara (a form of Mary) and Yehuda bar Yeshua (Judah, son of Jesus), Professor Fouerverger calculated there is just a one-in-600 chance that those same names would have come together in a family that didn't belong to Jesus of Nazareth. That calculation helped propel the already explosive story. "It was really the thing that began to convince us all to give this more attention," says James Tabor, chair of religious studies at the University of North Carolina, Charlotte, who advised the filmmakers and Professor Feuerverger, and appears in the two-hour documentary. But the one-in-600 calculation is based on many assumptions about the prevalence of the names and their biblical significance. For purposes of his calculations, Professor Feuerverger relied on new scholarly research [into fourth century Gnostic writings] that links the inscription "Mariamene e Mara" with a name for Mary Magdalene. (The filmmakers suggest that she was Christ's wife and that they are buried with a son, Judah-claims hotly denounced by traditional Christians.) Had the professor assumed the inscription could be for any Mary, a very common name then, it would be far less likely that Christ's family is in the tomb. The mathematical finding would become "statistically not significant," Professor Feuerverger tells me. Similarly, the name "Yose" -as one of Jesus' four brothers was called in the Gospel of Mark-is a derivative of Yosef, another common name. [The Aramaic and Hebrew word for brother/brethren ach/achim denotes both brothers in the strictest sense and more loosely cousins]. There, too, the finding would be less conclusive if the professor had considered "Yose" applicable to any Yosef. Even if there was consensus on the interpretation of the names, there are no comprehensive records showing how frequently they occurred in the population at that time. Professor Feuerverger relied on modern books about ossuaries and ancient texts to tally the occurrence of certain names in the area then. That falls short of a complete census. "As you pile on more assumptions, you're building a house of cards," says Keith Devlin, a Stanford mathematician and NPR's [National Public Radios] "Math Guy." (Scientific American also challenged the calculation on its Web site.) No one is questioning Professor Feuerverger's statistical credentials, or his calculation given the assumptions made. For each of the names believed to be appropriate for Jesus or an associate, Professor Feuerverger calculated the probability it would arise by chance, then adjusted for other factors, such as the number of tombs in Jerusalem. But his conclusion is only as reliable as the assumptions that went into it. "I wouldn't be comfortable coming up with a number like thiis,. because the general audience will not understand that it is very, very subjective," says Ivo Dinov, assistant professor of statistics at the University of California, Los Angeles. The case is far from closed on this tomb. Professor Feuerverger, who says he was paid a "nominal" sum for his work, had signed a non-disclosure agreement with Associated Producers, barring him from describing the project and so limiting his ability to run his work by his peers. He still hasn't provided full documentation of his calculation saying he'd wait until his paper, not yet completed, is accepted by a journal. "There is a mismatch between how the media works and how academia works," Professor Feuerverger says. "Obviously it would have been a whole lot better if I had completed the paper before the documentary aired. " Writer-director Simcha Jacobovici says he went to great lengths to find a responsible number. Initial, "ballpark" calculations based on the incidence of the names-including one made by Charles Pellegrino, co-author of the documentary's compaiuon book-found even smaller probabilities that the tomb wasn't that of Jesus' family. Mr. Jacobovici then turned to the University of Toronto, down the street from his production offices, and tapped Professor Feuerverger to do the calculations with greater rigor. "We told him Charlie came out with 2.4 million to 1," Mr. Jacobovici says. "He said, the numbers will come out where the numbers come out." All this has brought some measure of distress to Professor Feuerverger, who nevertheless says he thinks the experience will strengthen him as a human being, and as a statistician. "When I was doing the calculation, I was naively unaware of the extent to which the filmmakers might be depending on the ultimate result of it," he says. " I did carry out the calculation in every good faith. I hoped it would be interpreted in that light." |
