When I attended a course in Detroit in 2008, we meet with representatives from various groups that are trying to change the life of individuals and communities for the better. An example of that:
The mission of Gamaliel Foundation is to assist local community leaders to create, maintain and expand independent, grassroots, and powerful faith-based community organizations so that ordinary people can impact the political, social, economic, and environmental decisions that affect their lives; to provide these organizations with leadership training programs, consultation, research and analysis on social justice issues; to be a network for mutual learning environments and working coalitions.
