On Thursday, my local newspaper ran a quarter-page article on the translation of a newly translated approximately 3rd Century papyrus which quotes Jesus as referring to "my wife." Needless to say, if Jesus had a wife, that would be news to most of church history where there is almost nothing supporting such an idea other than a few heretical texts.
But, of course, that is the question regarding the Jesus Wife Gospel (which, given the fact that it is only a fragment of a work that may be very short, should not be called a Gospel at all). Is it an heretical text or is it something worth reading? In saying, "my wife", was Jesus (if he really did utter those words) referring to his bride, the church, or to an earthly wife?
Rob Bowman on his Religious Researcher blog, has published a page which he plans to keep updated with resources both in favor of and counter the authenticity of the Jesus Wife Gospel. You can find the resource here: Karen King's Jesus Wife Papyrus. There are a number of really good articles linked (and some of the articles linked also contain links to other resources.)
My favorite article of the ones I have read so far is No, People, a 4th Century Scrap Doesn’t Prove Jesus Had a Wife which concludes with this well-written non-conclusion:
Actually the only thing it shows is that one (potential) Christian writing in Coptic in a document that is incomplete may or may not have been referring to a tradition concerning Jesus that was held by only himself or perhaps a handful of others.
In short, what it shows is that even now, when people should know better, they still are more than willing to say more than can honestly and confidently be said.
Addendum: I found a follow-up article by Rob Bowman that makes the case against Jesus being married. It can be found here: Was Jesus Married? The Historical Evidence.
