Structures of Virtue and Vice

The paper argues for new concepts in theological ethics: structures of virtue and structures of vice. The Catholic tradition's development of the ‘structures of sin’ in the 1970's and 80's was a significant contribution to magisterial teaching. However, this concept should be updated in light of the trajectory and concepts of post-Vatican II theological ethics. The article proceeds in two parts. Part one recapitulates the development of the concept of structures of sin in the Catholic tradition from the Second Vatican Council to Pope Benedict XVI's recent social encyclical, Caritas in veritate . Part two reflects on the findings of part one, and proceeds to define and defend the concepts structure of virtue and structures of vice. These related concepts more accurately capture the moral nature of social structures. Social structures have the capacity to produce just or unjust outcomes, and to play a significant role in the character formation of persons. Therefore, the structures of virtue and structures of vice are offered as insightful ways of discussing the moral status of social structures.
