I reported on this story back in September 2012. See: Brief Reflections on the So-Called Jesus Wife Fragment. At that time, there was some debate concerning the authenticity of the fragment. On April 10, 2014 a new study was released, claiming that the papyrus fragment was ancient and not a modern forgery.
