Fr. James Martin, SJ, says it wouldn't bother him to learn that Jesus had a wife, but he doesn't think it's likely. From the NY Times:
It wouldn’t upset me if it turned out that Jesus was married. His life, death and, most important, resurrection would still be valid. Nor would I abandon my life of chastity, which is the way I’ve found to love many people freely and deeply. If I make it to heaven and Jesus introduces me to his wife, I’ll be happy for him (and her). But then I’ll track down Matthew, Mark, Luke and John, who wrote so soon after the time of Jesus, and ask them why they left out something so important.
