This has been a nonissue in the field of archeology for some time. The find itself is more than twenty years old, and the opinion throughout the realm of archeology is that although this is a significant find, the claim that the bones belong to Jesus and his family is not taken seriously. If archeologists really believed this claim, believe me, you would have heard of this before now.
What this story points out is how we view matters related to faith through our own particular world view. My initial reaction to the story - which continues to be my reaction - is to scoff at Cameron's claims because my belief is there are no bones of Jesus to be found. I believe in and affirm the historical Christian belief that Jesus was resurrected and that it was a bodily resurrection. Those who are skeptical or disbelieving of this claim will react to this news accordingly.
Will I watch the documentary on March 4th? I don't know. I may, depending on other plans, but I don't think I'll go to any great lengths to see it. I'm just not that interested in this program.
