"In the customary Catholic attitudes, in the established Catholic institutions, in the received Catholic structures, in the traditional Catholic theology, and in the official Catholic teaching, little if any provision has been made for the possibility of undergoing, let alone initiating, evolutionary change."

Those words were written by Leslie Dewart nearly half a century ago to describe why he believed the term "crisis" applied to the state of Catholic belief at the time.  Not a lot has changed, though Pope Francis is arguably trying to move the mountain.  To paraphrase Gamaliel, if the Pope's efforts represent God's work, obstruction isn't smart.

The Presbyterian Church may also be in crisis - I don't know.  If it is, it won't be because people like Bill and Eugene haven't tried to achieve change, and it won't be because the Presbyterian Church lacks structures that allow change to happen.
