The phrase “social justice,” when invoked by members of the Catholic left, is a euphemism for the agenda of the Democratic Party. “Social justice” refers not to objective principles of justice but to specific policies of Democrats on health care, labor, welfare, and other matters.
That from George Neumayr of Catholic World Report. Substitute "Christian" for "Catholic" and you've got a more comprehensive statement, no less true.
We also enjoy this one:
Voters were in no mood to hear about “social justice” from Catholic Democrats whose party during its time in power has presided over increasing poverty and unemployment.
And this one:
The Catholic left’s monopolistic claims about the “common good” and “social justice” now meet with appropriate skepticism, and its equation of “Catholic concerns” with amnesty, carbon taxes, government-run health care, and so on, is seen as insultingly specious.
Let us not forget that economic growth, enabled by liberty and the rule of law, have lifted more people out of poverty than all redistributive and protectionist policies put together. If you want to help the poor, you can't do it with socialism. Cornel West is famous for distinguishing "justice" from "charity." How about distinguishing a specially pleaded definition of "justice" from "opportunity"?
