I wonder about this, because both the Social Justice mission and the Pro-Life mission are not directly about helping individual souls attain eternal life in Heaven. Both are about justice and decency in this world. Both concern the material conditions of human life in this world.
Pro-Life always a life or death situation. Yet, in poorer nations, Social Justice also sometimes a matter of life and death too (due to lack of food, lack of medical care, civil wars breaking out over government oppression, etc.)
Or, maybe the Catholic Church’s Social Justice mission is a sub-set of its Pro-Life mission?
It seems like liberal-bent Catholics focus on Social Justice, and conservative-bent Catholics focus on Pro-Life. Maybe if these two were merged, the liberal-conservative divide in the Church would be healed?
