Well, yeah, faith and all. But that's why I personally believe that religion should be a very private and personal thing. No one will ever agree and nothing can be proved unless there's historical fact, so there's really no reason to try and put "faith" into law, schools, and force it on other people. Everyone has their own right to believe in something different, even if a book is telling you that you don't, you really do.
Which is why if Jesus had a wife, and it was proven historical fact, it wouldn't change much. Some people will still declare it a lie, others will add it in to their beliefs, others already thought it. So in the end, it's interesting, but it doesn't really matter.
Unless they find a living descendant of Jesus. Then that might be cool.
