Christian nationalism has emerged as an important component of the relationship between religious identities and political attitudes. While several studies have analyzed the constellation of Christian nationalist elites and the effects of Christian nationalist orientations on public opinion, to date no study has explored how Christian nationalist elites message to the public or what effects these messages have. Moreover, the current literature lacks comparisons of Christian nationalism to other similar orientations. This study uses content analysis to compare the content and use of emotion language of Facebook messages of Christian nationalist, Christian Christian nationalism (CN) opposition, and patriotic groups. I find that these groups focus posts on issues that are stereotypical to the group identity, and that the use of emotion language differs by topic and group type. Additionally, groups’ use of emotion language shifts the emotional responses of readers, especially in Christian nationalist groups. This study adds to our understanding of the role of emotion in social media communications and the effects of social media communications on readers.
