My dissertation, an exploration of the American Catholic feminist movement in its first seventeen years (1963-1980), analyzes the conjunction of feminism and faith in the lives of Catholic women, and the implications of this integration for both American Catholicism and feminism. In the 1960s and 1970s, thousands of women identified themselves as Catholic feminists, belying the persistent idea present in both Catholicism and feminism that the two are mutually exclusive. My project explores how these believers adapted the practice of their faith, and their understanding of church as institution, as they integrated the tenets of a reform movement into their worldview. Similarly, how did these reformers define their place as believers in a struggle often hostile to organized religion? For Catholic feminists, the conjunction of the two was not static; feminism profoundly changed women’s relationship to Catholicism as institution, community, and foundation of belief, while the lens of faith helped women devise creative and practical approaches to feminism that fit their understanding and experience. At a time when both Catholicism and feminism were simultaneously rooted in tradition and yet newborn, this diverse group of women used their writing, activism, liturgy, and prayer to redefine the parameters of belief and reform, and express their melded approaches to living both ideologies.
