yes, it was idle banter.........however, IF it is true, don't you think she WOULD have been a lucky lady?
BTW...back in 'those days'....a 'wife' didn't necessarily have to refer to a 'married' or 'sexual' type of woman relationship....it could easily have also referred to a woman who came in a cleaned and cooked (like a housekeeper).
When they were talking about writings on a piece of papyrus that Jesus supposedly had written saying "my wife"
Brian said "lucky lady".
I realize it's supposed to be idle banter....but....
