An excellent one volume dictionary with fairly succinct articles on many moral themes and questions related to Roman Catholic Moral Theology. Originally written in Italian, this is the Spanish version.
It is a must reference for moral theology and contemporary issues related to ethics. It needs to be updated
to the 2000 era, but its themes are treated in depth and with solid and helpful arguments. It needs to be translated into English simply because of its ecellent historical treatments of the topics.
