"There's a tendency nowadays to overlook the concept of "obligation," in things both religious and secular. An entitled generation thinks that when they attend Mass they're doing God a favor, when, in fact they have a sacred obligation to do so, and that it's offensive to God if they deliberately choose to ignore him!"

People should not go to mass because they are supposed to and are afraid of offending God.  I am sure that the all powerful God who is God and not some theologians abstraction is far beyond petty human notions of obligation and offense.  I think people go to mass because they hunger and thirst for an encounter with this transcendent God of unconditional love and acceptance.  They stop coming to mass because they are not finding it.
