Justice cannot be created in the world solely through good economic models, however necessary those are. Justice is created only where there are just people. There cannot be just people without a humble, daily work of conversion of hearts, or creating justice in hearts. Only thus does corrective justice spread itself. In this sense, the work of the pastor is fundamental, not only for the parish, but for humanity. As I’ve said, without just people, the concept of justice remains an abstraction. Good structures can’t be developed if they’re opposed by egoism, including that of competent people.
