Teaching the Faith, Forming the Faithful, a Biblical Vision for Education in the Church by Gary A. Parrett and S. Steve Kang, foreword by J.I. Packer. 
'Why does the church teach? And what should it teach?
In recent years, traditional Sunday school and education programs have declined in influence and effectiveness. Education in the church is often sidelined by other competing priorities, and our efforts become haphazard and random.
As a result, many Christians have not learned the fundamental doctrinal content of the faith. As a response, a growing number of church ministries have moved toward an emphasis on Christian spiritual formation. But churches must hold together education and formation, the teaching of the faith and the forming of the faithful.
In this comprehensive text, Gary Parrett and Steve Kang attend to both the content and process of educational and formational ministries. They set forth a thoroughly biblical vision for intentional teaching of the Christian faith, with a holistic concern for what and whom is taught as well as how and why.Fully apprised of developments in educational theory and pedagogy, Parrett and Kang propose a core curriculum for recovering the full scope of Christian proclamation and reinvigorating the teaching ministry of the church. Their vision has implications not merely for catechesis, but for preaching, worship, children's and youth ministry, and much more.
The body of Christ can become all that God intends it to be, through intentional practices that foster personal and corporate formation. Here is guidance for individuals and congregations on that journey.'
