Austin,

I disagree with your take.  Parables are in different places in the three synoptic gospels.  They are arranges such that they fit the message the gospel writer(s) wished to send to their intended audience.  And there is something quite interesting about the parable of the ten bridesmaids.  It is the only parable in which the judgement of the characters is announced at the beginning of the tale.  Curious, no?  Thanks for your take on it, Dave Henson.
