I appreciated this WV article — What does “social justice” really mean? Two excerpts:
The Bible makes social justice a mandate of faith and a fundamental expression of Christian discipleship. Social justice has its biblical roots in a triune God who time and time again shows His love and compassion for the weak, the vulnerable, the marginalized, the disenfranchised, the disinherited — you get my point. “For Christians, the pursuit of social justice for the poor and oppressed is the decisive mark of being people who submit to the will and way of God,” writes Tim Dearborn in “Reflections on Advocacy and Justice.”
Social justice is about creating kingdom space in the here and now, giving witness to the ultimate just society yet to come. So every time we use our voice and influence to get in the way of injustice — whether it’s human trafficking, economic exploitation, human rights abuses, or infants dying needlessly from disease and malnutrition — we provide a foretaste of God’s kingdom to come.
