In 2012, during a debate with Dr. Bart Ehrman, Dr. Daniel Wallace proclaimed that there had been a discovery of a 1st century fragment of the Gospel attributed to Mark. Textual critics have been waiting for over 5 years to finally see a 1st century manuscript only to receive some bad news today. As covered on the Evangelical Textual Criticism blog, if the fragment published about in the The Oxyrhynchus Papyri Vol. LXXXIII, is the one Daniel Wallace claimed was from the 1st century (and this looks increasingly likely) then it should at least be known now that it actually dates from the late second to early third centuries CE:
The absolute silence from Wallace, Habermas, Evans and others who promoted a 1st century dating is palpable, they all seem to have gone silent with this recent news. Hopefully more information can be made available soon. Thanks to Peter Gurry for the scan of the journal’s page on the dating of the fragment.
and God knows best.
