Eamon Duffy explores the first and longest section of the Catechism of the Catholic Church, its teaching on the basic framework of Catholic belief, as found in the Apostle's Creed. Drawing on material from a whole range of Christian tradition, from the scriptures and early fathers to the work of modern theologians like Hans Urs von Balthasar and Juan Luis Segundo, he traces the distinctive ideas at work in the Catechism, and assesses its faithfulness to the teachings of the council. His book provides catechists, priests, teachers and the general reader with a non-technical and fascinating guide to the Catechism, in the light of theological developments and debate in the Church since the Council. Illustrated with material from contemporary literature as well as theology and liturgy, it also provides an introduction in its own right to some of the most fundamental and urgent themes of Christian belief.
