This paper addresses the instructional challenges of teaching business ethics in a way shaped by Catholic Social Teaching (CST). Focusing on the concept of the Common Good in CST, I describe my use of a case narrative in classroom instruction to help students understand the concept of the Common Good and to perceive the variety of ways businesses can serve or undermine the Common Good in a small city. Through these pedagogical explorations, I illustrate the distinctive vision of business ethics that flows from CST.
