It looks like the so-called Gospel of Jesus’ Wife papyrus fragment has been shown to be authentic–meaning that it comes from a legitimately ancient document, and may represent a tradition going back to a fairly early point in Christian history:
A wide range of scientific testing indicates that a papyrus fragment containing the words, “Jesus said to them, my wife” is an ancient document, dating between the sixth to ninth centuries CE. Its contents may originally have been composed as early as the second to fourth centuries.
The fragment does not in any way provide evidence that the historical Jesus was married, as Karen L. King, the Hollis Professor of Divinity at Harvard Divinity School, has stressed since she announced the existence of the fragment in the fall of 2012. Rather, the fragment belongs to early Christian debates over whether it was better for Christians to be celibate virgins or to marry and have children. The fragment is weighing in on this issue, according to King.
“The main topic of the fragment is to affirm that women who are mothers and wives can be disciples of Jesus—a topic that was hotly debated in early Christianity as celibate virginity increasingly became highly valued,” King explained.
I blogged about the theological implications of this back when the fragment’s existence was announced. (Short version: there aren’t many.) There are ample resources in canonical Christianity to support the value of married and family life and the equality of the sexes. If anything, the existence of women disciples who were not linked romantically to Jesus seems to make a stronger case for equality.
