It seems to me this is a very good way for priests, bishops, and theologians to get together to really discuss what is a change in practice - a new vision of how to deal pastorally with something that was, before, dealt with more by rules and legal (canonical) systems.  

I think the story Cupich told of his grandparents sending a child to an institution against the advice of a priest is very telling.  The priest was not living the situation - by-the-book answers do not deal with real life.  (That happened to my mother and grandmother over issues of sterilization.  Real life vs idealized situations makes rote answers unworkable.)  

I also had not thought of different ways AL may be known to, useful to, used by Latino and African American families.  Would have loved to be a fly-on-the-wall to just be educated about different cultural issues.  Sometimes I am so blind

Hope for the success of this conference.  This is an example the USCCB should follow.  Dialogue - imagine it.
