Using an approach that involves great participation, this book admirably achieves its purpose. Not only does it impart adequate essential information on the communities, but also communicates the skills involved in their running. Although the work deals specifically with small Christian communities, it can enrich and open new horizons for groups of all kinds, not least those of youth. In addition, it sets the small communities in the context of the wider church. James O'Halloran is a Salesian who, following long years serving in schools, has worked with small Christian communities and groups on all continents for well nigh forty years as member, coordinator and promoter. This task he has carried out from the halls of academe to parishes and far-flung mission statements. His book Small Christian Communities, Vision and Practicalities is regarded as a seminal work on the subject.
