This was fascinating:

Basically, he posits that the word "inn" as in "there was no room for them in the inn" could very likely (and he uses his knowlege of Hebrew to back this up) have meant they weren't given place in the guest rooms of Joseph's relatives in Bethlehem.  This is also very plausible, he continues, because Mary had conceived outside of wedlock.  They could have been defending their family's honor and showing their disapproval of her behavior. 

He then says, "And therein perhaps lies a lesson for us today. How often do we refuse to give place to our own prodigals, not only in our homes but in our lives? I’m sure Joseph’s relatives thought they were being righteous by shunning Mary. Do we do the same thing when we do not unconditionally welcome our own children or those with whom they are in relationships into our homes? What if your child were gay? What if he had a partner? Is the righteous response to bar them from the family home? Should we tell them there is no room for them in our kataluma?"

The things we do in the name of "raising our children!"  We must know when to stop the artificial imposition of punishments and trust them to live their lives how they think best.
