Phizzy,
It has taken the NT world by storm. Prof. King acquired it more than one year ago. Most people in the field believed it was a forgery. Several items in the document are suspicious. Scholars have written journal articles about, if true, what "wife" might mean. It is hard to tell because it is a short fragment. NT scholars were curious as to why someone with King's reputation and Harvard would back such a document. The document was considered too short to conduct scientific tests. New technology allowed it.
MIT, Columbia, and other schools found it authentic. This was the big surprise. One school, WVU or VA, had strange results, dating it four or five centuries later than the others. Four or five independent schools agreed it was genuine. So about six samples were taken from a fragment.
It is a very big deal in the NT world. Where is the rest of the document? I skimmed about the Dead Sea Scrolls and the Gnostic gospel find at Nag Hammadi.The stories of how these items are found, the creation of international committees, the politics within the international committees, and the final research works are thrillers.
Dan Brown's Da Vinci Code and now this reference to a "wife" will lead to more popular books and academic articles. I never saw what was so alluring about Jesus not being fully human. The Roman Catholic crowd is not going to like this find. This is racy stuff. It will sell.
