If the Catholic community in the US is to survive as a coherent community ....
It's not clear here what is the definition of this "Catholic community" of what "coherent" is supposed to mean.  It seems to me that if the institution does not establish that it is meaningful, ever more people will drift away.  In time, the term "Catholic" will become a historical artifact, not a contemporary term.  
As it is, despite the cosmetic changes, the institution seems bent on becoming irrelevant in the daily lives of most people.
