If somebody can find that old thread and post a link to it that would be great, I can't track it down at the moment.
Steve, remember that on the cross Jesus instructed John to take care of his mother (John 19:17). If he were married, would it not have been an even higher priority for him to hand on his wives to the care of another man? Wouldn't he have asked disciples to take them on just like his mother? This suggests very strongly to me that he was not married.
It doesn't really matter theologically of course, but if he had children that would cause theological issues as pointed out by Paul.
Children were a vital part of the culture of the day, as they would provide for their mother in her old age. Our modern culture has embraced the idea of sex being primarily for pleasure and marriage not being about children, but this is a modern perversion in my view. God created marriage to fulfil His command to "go forth and multiply". A Godly marriage would therefore be aimed at least partly at fulfilling this command (notwithstanding that sometimes that is not physically possible). Christ's marriage would be perfect, and therefore would fulfil all aspects of marriage, including this one. Which would mean children, and therefore a theological mess.
And then he would have left at least one young widow, either barren or possibly with very young children, with the Romans chasing after her... I can't imagine this being something He would do.
So it is plausible that he could have married. But when you think of the wide range of issues around it, I believe it is highly unlikely.
