In an article for The Catholic Worker, Dorothy Day articulated this well: “Can I talk about the people living off usury . . . not knowing the way that their infertile money has bred more money by wise investment in God knows what devilish nerve gas, drugs, napalm, missiles, or vanities, when housing and employment . . . for the poor were needed, and money could have been invested there?” Her thoughts were a precursor to what Pope Francis now calls an “economy that kills.” To sin is to say “no” to God and God’s presence by harming others, ourselves, or all of creation.
