Jesus lived in a particular time and particular place.  What we know about Jesus was written by people who were not present during His life.  
As has been said by many, his apostles are all said to have been fisherman, probably all went barefoot in sandals, did not wear underwear, did not use deodorant, did not bathe frequently, spoke Aramaic, all had beards, did not wear pants or clerical collars..... Few of our current priests (at least in the US) satisfy these criteria.  And, yet, the Church survives.  I think that it would survive women priests, despite any declarations or even "unchangeable" pronouncements -- which HAVE changed over time.
