What do you understand Matthew's divinely revealed dogmas from Christ? "Depart from me you evil doers". For when I was sick you did not visit me?
I wouldn't use the word 'social justice' because it has acquired a very political agenda. Many people who accept Christ's social teaching nevertheless reject the phrase 'social justice' because of how political it became. So yeah in terms of the Christian social teaching, we need to visit and help the sick, and aid the poor. One may be 'sick' and 'poor' in a number of different ways: -physically sick/poor, -emotionally sick/poor, -or spiritually sick/poor. One may be physically poor, which would mean that we give them alms and charity. Or one may be spiritually poor, and abuse the alms they receive to finance an addiction, or a life of laziness. So it has sometimes been a practice of Christian social teaching to be harsh on the paupers, even to put them into prison, to help to teach them that "those who do not work, do not eat." So Christian social teaching is varied, multi-faceted, and multi-dimensional, and it is a real privilege to be a part of its reach history.
