The introduction outlines three key concepts framing the book: faith, labor, and power. It explains the biblical foundation of the oneness Apostolic church in the study and places it within the context of Holiness-Pentecostalism. The analysis of faith takes place in a larger conversation with literature on twentieth-century Black American Christian women, which informs the study’s findings. At the same time, viewing churchwomen’s work as labor is a crucial departure from existing studies. Engaging late twentieth-century feminist labor theories enables analysis of material and immaterial labor. This, in turn, opens the way to understanding the work entailed in gender power negotiations, which has historically been central to Black women’s church work. The chapter continues with a description of the methodology and concludes with chapter overviews.
