Dating tests performed on a controversial piece of papyrus which suggests that Jesus had a wife have found that, contrary to claims of a hoax, it is indeed an ancient document:
Since Harvard professor of divinity Karen L. King publicized the so-called “Gospel of Jesus’s Wife” in 2012, scientists and theologians have fiercely debated the authenticity of the fragment — the only known papyrus containing the words “Jesus said to them, my wife.” Biblical scholars have argued that the 1- by 3-inch chunk of papyrus is modern, “oddly written” and a “clumsy forgery.” But results from recent chemical and handwriting analyses say otherwise.
…Scientists used a technique called micro-Raman spectroscopy, which measures the way objects scatter photons from a laser, to determine the chemical composition of the ink used to write the “Gospel of Jesus’s Wife.” The chemical composition of the ink dated back to between the sixth and ninth centuries, or earlier, and matched other samples from the same time period.
A second study examined the fragment’s handwriting to verify its authenticity. King, at Harvard Divinity School, weighed all the evidence and concluded that the fragment is likely a product of early Christians, not a forgery. The findings were presented in a series of studies published Thursday in the Harvard Theological Review.
Note that this does not necessarily prove that Jesus was married, but it certainly provides additional evidence for those wanting to build such a case (though if you’re a fiction writer who think s novel based around that idea could be a bestseller, you’re about a decade late…).
