"I often say that there is no problem that would not be made better is given the leaven of Catholic social doctrine."
Those are probably the most profound words of this heavy and profound editorial comment.
One might ask: where was/is it?
The "social" dimension has been so absorbed into institutional ideology and warped that it has become   in fact divisive, impotent, abused.  The institutional church has shown that it cares more about itself and its ideological and political intransigence - elevated to "doctrine" - than the "social", the community of persons.
By "Catholic" I also mean that we have coopted what is human, human values, responsibility, accountability, and virtue into pseudo-religious ideology rather than giving the redeeming Christ His rightful place as a civilizational leader. 
"Catholic social doctrine" is first civility - THE natural law of community, of nation. Jesus came to it, of it, He furthered it and as a profound intellect He furthered it AND then elevated it.
