This article examines the relationship between prayer practices and gendered subjectivity among a group of millennial-generation Catholic men and women. Drawing on ethnographic work, this case study illuminates the role of prayer in shaping how, why, and with what sorts of struggles young and culturally-savvy women and men embodied gender complementarity in the twenty-first century U.S. This article proposes gendering prayer as an analytic for understanding how prayer cultivated these Catholics in the habits of feminine genius and authentic masculinity. By comparing women’s and men’s practices, I argue that these young adults were flourishing in the modern world, even as they rejected egalitarian gender roles in favor of multiple modes of submission within gender essentialism. This work contributes to anthropological scholarship focused on gender performance in daily Catholic life.
