Some things in the name of social justice has been abused of course. However that does not mean that the concept of Social Justice is that a reality that is grounded in the reality of Christ
"However that does not mean that the concept of Social Justice is that a reality that is grounded in the reality of Christ"
I'm not sure what you are trying to say here (maybe a typo), but here is my take:
"Social Justice" is a Marxist concept, not a Christian concept. Everytime I hear or see it used, I cringe.
For the *Christian* concept, go to Saint Thomas Aquinas and look at *Justice*. There is no need to qualify "Justice", it is both a virtue and a societal good all on its own.
We should have justice in society and in our personal behavior. Now, inequality in social orders or society are not necessarily unjust, but on the contrary are a needed part of any social order (think popes and deacons).
But the "Social Justice" crowd pursue marxist views on what justice is, focussing on economic equality (and the undermining of social order) as their prism for 'social justice'. It is wrong, bad for people (socialism is the #1 cause of poverty in the world today), and un-Christian.
Take the socialism out of "social justice" and you might be left with the real christian 'justice' concept.
