Fifty years since Vatican II, thirty years since Pope John Paul II called for a new comprehensive summary of Catholic doctrine, twenty years since the document was completed, a significant number of people are unaware that it even exists, let alone being familiar with its contents. And yet, broadly speaking, the Catechism of the Catholic Church simply articulates and elaborates what we say every Sunday in the Creed, the way we strive to live morally and ethically, and the way we communicate with God in prayer. The Catholic Update Guide to the Catechism of the Catholic Church explores what it is and how it is different from previous catechisms and walks through its four pillars--creed, sacraments, morality, and prayer.
