I follow a range of people on Twitter and on the issue of this small fragment of papyrus they fall into two camps:
1. The academics like Larry Hurtado, who sums it up in this article (worth reading in full as it mentions the problems with the Coptic in the fragment - for more on this see Mark Goodacre):
.... even if authentic, the fragment would have no bearing on (1) the marital status of Jesus of Nazareth, (2) the question of women’s role in churches, (3) the question of Catholic priestly celibacy, etc. None whatsoever. Nada.
2. Atheist critics, who seem to have seized on the fragment's recent early carbon dating by MIT and Harvard as evidence that it must be true and therefore the gospel accounts of Jesus life aren't.
The odd thing, of course, is that the carbon dating puts it at 700AD, far later than the canonical gospels. If any of the four canonical gospels were found to be from 700AD the same critics would be using that dating as evidence that those documents could not be accurate. I guess that a late date can be used to cut any way you want it to.
