This text on the theological and cardinal virtues of the Christian life asks the question: how can believers decide the moral good and live accordingly? It reflects on basic questions of Christian morality, offering a commentary on the corresponding sections of the Catechism of the Catholic Church. "C.'s discussion of justice is the most brilliant and helpful in this work...As we read his [Cessario's] rigorous analysis and observe his devotion of Mary, we see that C. himself is demonstrating the virtues of knowledge and piety in his theological reflection." -Theological Studies, 6/04
