The archbishop seems very myopic.  In democracies, numbers matter.  If our numbers shrink, our ability to resist evil in society will also shrink.  
What is the archbishop doing to bring fallen away Catholics home?  I never hear any creative ideas from him on that front.  
If I was an archbishop, I'd be out there talking to ex-Catholics about why they should give the Church another chance even after the abuse scandals.  Sadly, I suspect our bishops won't go near that kind of work because they are afraid of what they might hear from people.  
Archbishop Chaput wishes a smaller, more "loyal" Church.  What he will probably get is a Church where most Catholics care about the Pope and their parish -- and nothing in between.
