The special section of this issue of AJPH (pp. 361–386) highlights the wide range of existing and potential partnerships between public health agencies and faith communities across domains of public health practice and religious traditions. The work of religious institutions serves as a determinant of population health in a key way by providing social capital to individuals and communities. Despite longstanding historic distrust and skepticism (in both directions) between people and institutions associated with the respective faith-based and public health sectors, partnerships have arisen in which the interests of both are aligned for the health of their communities.
