There is obviously a change happening in how people want to worship and how they want to form a worship community.  This is as true among Catholics as among other religious groups.  Judson is an example of a different ways some non-Catholics have responded.  There are lots of calls for change among Catholics - just look at recent articles here and in other sources.  

What has given momentum to the calls for change is how quickly Australian and Irish Catholicism have ...well...crash landed.  It doesn't help that bishops almost everywhere refuse to even admit a problem with declining participation and a declining priesthood until way too late.  They still totally ignore a declining acceptance of the patriarchal/authoritative nature of Church governance and the rejection of some teachings.  

So, since they won't deal with it, we all need to be thinking about what alternative structures would help us live out a faith in Jesus and pass on that faith to a new generation.
