Spiritual Charity is the real motor of social change. Lovingkindness - unselfish, not proud, not greedy, based on pure natural supernatural affection & devotion - the spiritual force adumbrated most eloquently in Paul's epistle - this is the force behind the betterment of life everywhere on earth, in all its facets and modes.
Because spiritual Charity lends meaning to this familiar Gospel comment : "The greatest among you shall be your servant." That explains everything about both mercy and social justice.
