It is very exciting news that the scientific tests have come back with a thumbs up for the antiquity of the papyrus fragment that mentions Jesus' wife and her discipleship.
The fragment is now dated between the 4th and 8th centuries according to the latest reports.
When it first came out, I suggested that it was a fragment indicative of Valentinian Gnostic theology where Jesus and Mary Magdalene were spouses, and she was his disciple. I see no reason to alter this opinion now that the reports have come back on the document's antiquity.
There is more to read about this in the New York Times HERE. Now that its antiquity has been authenticated, Karen King's article on the Gospel of Jesus' Wife is finally being released in the Harvard Theological Review HERE.
This whole "event" has impressed upon me again the problems that we have with our traditional forms of biblical analysis which rely on outdated concepts of "sources" and "redaction" and "dependence." It brings home that we should be cautious and humble about what we can really know and what we can't. Sometimes history can surprise us.
