The recent Church Growth Research (see www.churchgrowthresearch.org.uk) identifies that the successful transmission of faith to children and young people is a key factor in stemming decline and promoting growth. This book explores the cultural and theological reasons as to why this is the case and makes research-based recommendations for the faith formation of children and young people. The central argument is that church communities need to engage in deliberate strategies that help foster 'intentional Christian Communities' within which children and young people can form and sustain Christian identity.
