The book gives a comprehensive detail of the meaning and formation of Small Christian Communities and how they can help in grassroots evangelization. These basic communities also help in deepening the faith of Christians. The book gives in detail the benefits that can be derived by Christians' membership of these basic Christian communities and outlines structures for practical use of parishes that would want to form the communities. In driving home her points, the author has made use of the scriptures quoting the relevant references and also the views of the Fathers of the Church and the Hierarchy were well articulated on the subject matter.
According to the author a Small Christian Community (SCC) is a group of people, usually few Christians, who share their faith values. They meet on a regular basis to share the faith, support one another, socialize, or provide services to the parish, members of the group or the needy while deepening their faith through studying the Bible and the Church's teaching. By so doing evangelization would be effective in bearing its fruits in line with the view of Mother Teresa of Calcutta which is having Christ in one's heart and making him present in the heart of others.
