In arguing that Jesus was interred in the Talpiot tomb, the team behind the new James Cameron documentary note that the tomb did not include the remains of Jesus' father Joseph, who judging from the biblical narratives seems to have died before the family relocated to Jerusalem. 

Not that the filmmakers necessarily think that Joseph is Jesus' father.

In The Jesus Dynasty, James Tabor--a scholar who helped shape the documentary in question--explores the ancient rumor that Jesus was actually the son of a Roman soldier named Pantera.  Tabor recounts key points from his argument in this blog post.  But there's more to the story than Hebrew and Latin texts.  As Tabor notes, we actually know the location of the grave of a first-century CE soldier named Tiberius Julius Abedes Pantera. 

And so it seems that the future of Christianity may rest with Maury Povich.
