In the first history of laywomen and the church in colonial Mexico, Jessica L. Delgado shows how laywomen participated in and shaped religious culture in significant ways by engaging creatively with gendered theology about women, sin, and guilt in their interactions with church sacraments, institutions, and authorities. Taking a thematic approach, using stories of individuals, institutions, and ideas, Delgado illuminates the diverse experiences of urban and rural women of Indigenous, Spanish, and African descent. By centering the choices these women made in their devotional lives and in their relationships to the aspects of the church they regularly encountered, this study expands and challenges our understandings of the church's role in colonial society, the role of religion in gendered and racialized power, and the role of ordinary women in the making of colonial religious culture.
