Faith-Based Community Organizing (FBCO) or Congregation-Based Community Organizing (CBCO) brings congregations of diverse religious backgrounds together to work within their local community on issues that are of concern to that community. Members of faith-based community organizations cross religious, racial, ethnic, class, and social lines come together for the good of the community. Often working with local unions and community organizations (as member organizations), faith-based community organizations determine from one-to-one conversations with community members and members of their own congregations and organizations what issues  are most important to address. Through voting by the membership, the faith-based community organization may take on one to three issues. A few of the issues that the Pioneer Valley Project, itself a faith-based organization, has take on over the years include: redevelopment of abandoned housing, helping residents become homeowners, and creating a teacher home-visit program to make schools more accessible to parents which in turn helps the students.

PVP works with individuals from its member organizations and the community who then become leaders through its ongoing training process. The leaders are identified because they are people who have passion and knowledge about the issue being addressed and they are able to bring others along with them to work on the area of concern. Working within the faith communities doesn't just bring powerful voices to communities; it also revitalizes congregations and makes them stronger through the relationships that develop between the congregations and within the congregations themselves.
