Let me say preemptivly that I don't know anything else about the document than what has been made public, nor am I the right person to discuss the ethics of deconstructing these masks in search of gospel fragments, but Prof. Evans is one of my doctoral supervisors and I know he's been trying to correct some misinformation that's been spreading so I am posting this statement he's released for those who are interested:
"Last summer I gave a presentation on the number, age, and reliability of New Testament manuscripts. In this lecture I described the effort under way in recent years to recover manuscript fragments, including biblical manuscripts, from ancient cartonnage, including mummy masks. All of these materials are from Egypt. Just over three years ago a fragment of Mark was recovered, which those studying it think dates to the 80s. If they are correct, this will be the first New Testament manuscript that dates to the first century. The fragment is to be published later this year (by E. J. Brill). Someone video-recorded my lecture and posted it on YouTube.
"Last week a reporter, Owen Jarus, from Live Science contacted me and I gave him an interview. What he wrote was posted on Sunday 18 January 2015 and is accurate. However, other journalists have made use of his story and/or the video on YouTube and have misunderstood some aspects of it, claiming incorrectly that I was myself the discoverer of the fragment of Mark or that research on the papyri recovered from the mummy masks is going on here in Nova Scotia. Some have also posted a photo of a mummy mask giving me credit for the photo. The photo is not mine. I have directed reporters who inquired to the person to whom the photo does belong. Unfortunately, not all reporters inquired. The Live Science link is http://www.livescience.com/49489-oldest-known-gospel-mummy-mask.html."
