Food for Thought

A Catholic university is called to become an evermore effective instrument of cultural progress for individuals as well as for society. Included among its research activities, therefore, will be a study of serious contemporary problems in areas such as the dignity of human life, the promotion of justice for all, the quality of personal and family life, the protection of nature, the search for peace and political stability, a more just sharing in the world’s resources and a new economic and political order that will better serve the human community at a national and international level.
