Charity is commendable; everyone should be charitable. But justice aims to create a social order in which if individuals choose not to be charitable, people will not go hungry, unschooled or sick without care. Charity depends on the vicissitudes of whim and personal wealth; justice depends on commitment instead of circumstance. Faith-based charity provides crumbs from the table; faith-based justice offers a place at the table.
