The local news was talking about how he was into "social justice" otherwise know as socialism. Not sure were they got their information. If true, already I don't like him.
The true social justice mission of the church is inextricably tied to the concept of subsidiarity.
Subsidiarity insists that the smallest or most local organization that can address a problem should address a problem.
Therefore, an individual is obligated to help himself, his family, his neighbor. The church is organized throughout the world on a local level to serve the poor, educate children, build hospitals and provide ministry programs for all.
There is very little in terms of helping the poor that required a large federal government. That is Catholic teaching, although the concept is not properly promoted by many in the media and more unfortunately by many in the church.
