For a long time, Trappist monks and nuns have been known for living a simple and silent life. As I am writing a book about Trappist culture, I have found that Trappist monks are actively engaged in commerce. Normally, we believe that Trappist monks and nuns build a culture of “service and selflessness” in their monasteries. So I wonder: why do Trappist monks and nuns participate in business activities? Is this in conflict with their religious faith? Do people like Trappist beer?
