Abstract
St. Vincent de Paul (1581–1660) is well known for his contribution to charitable and social works. Even though he left no detailed examination of his business practices, by examining his life and his commitment to the poor, it is possible to frame a Vincentian theology of business ethics. Such an understanding would include educating students in the social teaching of the Catholic Church, a preferential option for the poor, good organization, sound business theory, economizing, and a foundation in the liberal arts.
