Abstract This article considers the analytic categories scholars use to conceptualize religious difference in the Caribbean and addresses the relatively sparse theorizing of Christianity in the study of so-called syncretic or creole religions of the African diaspora. I take the Spiritual Baptists of Trinidad and Tobago as a case study to shed light on the significant divergences between vernacular definitions of Christianity and those designations scholars use to parse and make sense of Afro-Creole diversity. I am especially interested in what is at stake analytically. Spiritual Baptists challenge conventional articulations of Christian orthodoxy and Black Atlantic religiosity by reconciling a “fundamentalist” Christian identity with an especially fluid cosmopolitan eclecticism. Drawing on comprehensive ethnographic research, I show how the unique permutations of creole variation within Spiritual Baptist faith unsettle deterministic equations of race and religion and contest the often manufactured oppositions between Christianity and African religion.
