Shar-M, I am not even sure they know what to do, what to change.  Do they care?  The loss of trust is so massive in some places in Europe, Ireland, Canada, U.S., Australia that it undermines believability in what they say are truths in the faith itself.  It wasn't just the sex abuse scandal, but also issues like contraceptives, in vitro fertilization, sexual ethics, confession (most Catholics don't bother any more), even all the to-do over Mass translations - so many other things.  

I don't think we can restore trust in the relationship as it used to be.  I am not a child and a priest or bishop is not my father; nor am I a sheep and he is my shepherd.  What we need is a new relationship, one that is based on respect for the intelligence, knowledge, and adulthood of the laity.  One that respects women as equal to and as capable as men. And one that lets us inside their heads, inside the functioning and decision making of the Church.  

Probably not gonna happen - ever? for a long time?
