186 There is a kind of love that is “elicited”: its acts proceed directly from the virtue of charity and are directed to individuals and peoples. There is also a “commanded” love, expressed in those acts of charity that spur people to create more sound institutions, more just regulations, more supportive structures. It follows that “it is an equally indispensable act of love to strive to organize and structure society so that one’s neighbour will not find himself in poverty”. It is an act of charity to assist someone suffering, but it is also an act of charity, even if we do not know that person, to work to change the social conditions that caused his or her suffering. If someone helps an elderly person cross a river, that is a fine act of charity. The politician, on the other hand, builds a bridge, and that too is an act of charity. While one person can help another by providing something to eat, the politician creates a job for that other person, and thus practices a lofty form of charity that ennobles his or her political activity.
