Karen King of Harvard Divinity School made the announcement today.
From the New York Times:
The faded papyrus fragment is smaller than a business card, with eight lines on one side, in black ink legible under a magnifying glass. Just below the line about Jesus having a wife, the papyrus includes a second provocative clause that purportedly says, “she will be able to be my disciple.”
The press release from HDS might be available here. (h/t David Brakke)
Of course, as the Times piece points out, the fragment is hardly reliable historical evidence for the claim that Jesus was married. Written in Coptic, it dates from several centuries after Jesus’ death and its provenance is uncertain.
