This project examines how the racial composition of congregations—Black, multiracial, or White—shapes party identification among Black adults across the lifecourse, and how racial centrality—the degree to which Black identity informs self-understanding—mediates this relationship. Using the Faith Among Black Americans Study (FABS), I test whether younger and middle-aged Black adults, who increasingly worship in multiracial or predominantly White congregations, display weaker racial centrality and looser Democratic attachments compared to older adults whose political commitments were forged in historically Black congregations. The project advances theory by integrating perspectives on racialized organizations and congregational identity to show how congregations either affirm or decenter the role of race. It extends my published work, demonstrating that worship context shapes inequality frames and partisan orientation. I am uniquely positioned to lead this study as both a scholar of religion and race—with publications in leading journals—and an ordained Baptist minister with deep partnerships across Black denominational networks. Findings will clarify how generational and congregational shifts influence Black political life and provide clergy with tools to sustain racial affirmation and civic engagement. Dissemination will include peer-reviewed publications, clergy-focused briefs, and outreach to denominations.
