Book excerpt: From the Introduction This book is about passing on the faith from generation to generation, throughout the milestones of a person's life. Faith is created and nurtured by the Holy Spirit through the Gospels. The vision underlying the RADICAL model was developed in light of the theological principle that faith is formed by the Holy Spirit through personal, trusted relationships, often, but not always, in our own homes. A youth and family ministry for the 21st century connects all the generations in the total ministry of the congregation and, through the cross of Christ, recognizes the work of the Holy Spirit shaping faith in all the circles of relationships. This revised edition expands on the authors' original model in an all-new chapter on the circle of creation. This edition has also been updated throughout in light of new ideas and research that have emerged during the past decade.
