A new text recently discovered seems to indicate that Jesus referred to himself as having a wife. From a Harvard Divinity School press release:
Four words on a previously unknown papyrus fragment provide the first evidence that some early Christians believed Jesus had been married, Harvard Professor Karen King told the 10th International Congress of Coptic Studies today.
King, the Hollis Professor of Divinity at Harvard Divinity School, announced the existence of the ancient text at the Congress's meeting, held every four years and hosted this year by the Vatican's Institutum Patristicum Augustinianum in Rome. The four words that appear on the fragment translate to, "Jesus said to them, my wife." The words, written in Coptic, a language of ancient Egyptian Christians, are on a papyrus fragment of about one and a half inches by three inches.
"Christian tradition has long held that Jesus was not married, even though no reliable historical evidence exists to support that claim," King said. "This new gospel doesn't prove that Jesus was married, but it tells us that the whole question only came up as part of vociferous debates about sexuality and marriage. From the very beginning, Christians disagreed about whether it was better not to marry, but it was over a century after Jesus's death before they began appealing to Jesus's marital status to support their positions."
