Abstract
American Catholicism today struggles to sustain its longtime character as a truly “public religion”—that is, a religious tradition with a vital presence within the public sphere in the US. Reinvigorating Catholicism in the US will require both internal renewal and new approaches to public life, both of which will require continuity with the deep tradition and significant reorientation of ecclesial dynamics. This paper argues that specific, faith-based community organizing practices can help renew the public voice of Catholicism. In adopting such practices and inflecting them through Catholic commitment to theologically coherent processes of leadership formation, American Catholicism can reinvigorate parish life and play a crucial role in reconstructing democracy in the US for a multiracial and multifaith society in the twenty-first century and beyond.
