A fragment in Coptic seems to mention Jesus' wife: http://www.nytimes.com/2012/09/19/us/historian-says-piece-of-papyrus-refers-to-jesus-wife.html?_r=1. Everyone else in my blog circles is mentioning it, so I thought I would too.
How does this affect me as a Christian? Not at all for pretty much every reason. First, it dates from the 300s, so it does not likely shed any light at all on the historical Jesus. All it tells us is that some Egyptian Christians in the 300s thought Jesus had a wife, which is interesting in its own right.
But more interesting to you is probably the fact that, while there is no evidence that Jesus was ever married, I don't think it would matter one iota to Christian faith if he had been. Jesus was fully human, so I think it's fair to assume that he had sexual desires. I can't think of a single theological issue with Jesus being married, except that children would have been really theologically complicated.
Surely the knee jerk offense some take at this suggestion is some latent sense that sex is dirty. Since it isn't--and since the Bible seems silent on the issue--I can't see any biblical or theological problem with this thought experiment that, alas, is forever a thought experiment.
