First, it is important to understand the purpose of NCC—its goal is to introduce the almost-lost pedagogical method of catechesis to a new generation, and to direct and motivate far more people to study and learn the longer and historic catechisms than are doing so now. There are three features of NCC that we hope will accomplish this. One is its form as a free app. It means that people will be able to study and memorize the catechism within the fabric of their current, overly busy daily lives. It means that pastors and leaders who want to take a group or class or church through it will not need to make any purchases at all, but will only need to work out ways to use the catechism within their church's pathways of discipleship and training. A second feature is the language. We carefully sought to use modern but not colloquial language, seeking to be accessible but also graceful in style, but also harking back and using the style and language of the historic catechisms where possible.

In my previous post on this subject, I outlined how crucial the practice of catechesis is for the church, particularly when it is surrounded by a culture antagonistic to Christian teaching and truth. But, we may ask, “Why write new catechisms? What’s wrong with the older ones?”

After the high tide of the early centuries, the ministry of catechism diminished until the Reformation, when there was literally an explosion of catechism writing. T.F. Torrance edited a book that contains only catechisms that were used widely in the Reformed Churches of Scotland in the 16th and 17th centuries, and he provides ten. (See The School of Faith: The Catechisms of the Reformed Church, James Clarke, 1959.) A first thought of a reader of this volume may be, “They all agree on basic doctrine—then why so many?” The answer is in the first lines of Torrance’s introduction: “The Catechisms set forth Christian doctrine at its closest to the mission, life, and growth of the Church from age to age, for they aim to give a comprehensive exposition of the Gospel of Jesus Christ in the context of the whole Counsel of God and the whole life of the people of God.”

On October 15, The Gospel Coalition in partnership with Redeemer Presbyterian Church will launch New City Catechism—a joint adult and children's catechism consisting of 52 questions and answers adapted from the Reformation catechisms, available on iPad and online.

The church in western culture today is experiencing a crisis of holiness. To be holy is to be set apart, different, living life according to God’s Word and story, not according to the stories that the world tells us are the meaning of life. The more the culture around us becomes post- and anti-Christian, the more we discover church members in our midst, sitting under sound preaching, yet nonetheless holding half-pagan views of God, truth, and human nature, and in their daily lives using sex, money, and power in very worldly ways. It’s hard to deny what Gary Parrett and J.I. Packer write:
