This essay explores the intersections of religious ethics and American religious history and advocates for a transdisciplinary approach to scholarship in both disciplines. Four books, each published within the last 4 years, form the foundation of this discussion by modeling distinctive elements of transdisciplinary scholarship: Heathen: Religion and Race in American History by Kathryn Gin Lum; Make Yourselves Gods: Mormons and the Unfinished Business of American Secularism by Peter Coviello; Peaceful Families: American Muslim Efforts Against Domestic Violence by Juliane Hammer; (...) and The Sex Obsession: Perversity and Possibility in American Politics by Janet R. Jakobsen. Each of these texts raises questions that hover at the intersections of religious ethics and American religious history, demonstrating how scholarship in both areas can be strengthened through a destabilization of the disciplines themselves.
