After reading the article it doesn't seem an attempt to take down Christianity so much as an attempt to make money off of its more gullible adherents by selling them books and getting royalties from Discovery Channel specials. Nope, folks like these don't want to take down Christianity - to do so wouldn't be profitable for them.
What's ironic is that that Chrisitans who protest against this sort of junk archaeology seem not to be too bothered by junk archaeology by Christian apologists out to 'prove' the historiocity of biblical events.
That's actually what Simcha Jacobovici does most of the time.
Really, neither Jacobovici or Tabor are trying to take down Christianity. Tabor believes the earliest understanding of resurrection didn't preclude physical remnants. While I don't find it persuasive, he makes his case
here.
In College took a class on the Apocalypse, and Tabor came one time to speak as a guest lecturer about how the FBI's ignorance of the Book of Revelations and the Branch Davidians theology played a role in the tragedy at Waco. He seemed like a really bright fellow. Too bad he's succumbed to the sensationalism recently ubiquitous in NT studies.
