A new take on the Christmas story

You must listen to Greg Koukl's podcast from December 20 (found on str.org or my redirect page).  He discusses the historical account of the Christmas story, and suggests that instead of the traditional village inn, Mary and Joseph stayed at a relative's house.  The Greek word that has been translated as 'inn' is actually the same term used for 'the upper room'.  Bethlehem was a tiny village and likely didn't even have an 'inn'.  Most guests would stay in the upper room of a relative's house, and the animals were kept in the lower area.  However, if Mary and Joseph were late in coming to Bethlehem, and their relative did not have room left in the upper room, they would have had to stay in the lower room of the house, not necessarily a cave.  The idea that they stayed in a stable cave didn't come up until the 3rd century, probably shortly after such caves came into existence.
