This paper discusses the history and current manifestations of white Christian nationalism, with a focus on the implications for religiously minoritized people and groups in the United States. Emphases within include: the problematic responses to this phenomenon--including claims that Christian nationalism is not "real" Christianity and promoting an idealized secular neutrality--which are harmful to religiously minoritized people, and the discourse around ethno-religious nationalist movements in other countries around the world. The paper ends with an outline of future research in this area that would help improve our understanding of how to best respond to white Christian nationalism in ways that consider the experiences of religiously minoritized people and groups.
