The claim that the family tomb of Jesus has been found with his ossuary or bone-box identified in it as Yeshua bar Yosef (Jesus, son of Joseph) dances along the delicate interface between history and faith.
I do not presume that one can ever make an act of religious faith in the veracity — or mendacity — of an historical fact but only in the meaning, interpretation, or understanding of an historical fact.
I try, therefore, for my own integrity, to distinguish but not separate historical from theological judgment.
It is a first-century tomb with six inscribed ossuaries of secure provenance and closed chain of control. The inscribed names are all common first-century ones but this is the question: is this cluster of names so similar to those closely associated with Jesus that it must be his family tomb beyond a reasonable doubt?
Further question: how, why, when, and by whom was this tomb disturbed in antiquity?
Conclusion: go excavate it properly and professionally.
Next, theology. I myself am not convinced — but could be persuaded — that this is the family tomb of Jesus. Were I convinced, it would neither destroy my Christianity nor destroy my faith in the resurrection of Jesus.
I have always believed that resurrection is a metaphor but a metaphor about the body of Jesus, a belief that he was crucified by Rome and raised by God so that, in other words, God is — as always — on a collision course with Empire.
Finding the bones of Jesus would not disturb my faith but finding they bore no wounds — ah, that would be another matter.
