In a world where economic troubles and continuing wars preside, many people might search for spiritual guidance. But what does it mean to have faith in a world where politics rule and religion divides? That’s one of the questions addressed broadly in a new book by the archbishop of the archdiocese of Chicago Cardinal Francis George. The book is called The Difference God Makes: A Catholic Vision of Faith, Communion, and Culture. The Cardinal discusses the book, and his own role in the city’s culture.
