Attitudes toward immigrants and immigration policies are divisive issues in American politics. These attitudes are influenced by factors such as political orientation and religiousness, with religious and conservative individuals demonstrating higher prejudice toward immigrants and refugees, and endorsing stricter immigration policies. Christian nationalism, an ideology marked by the belief that America is a Christian nation, may help explain how religious nationalist identity influences negative attitudes toward immigrants. The current research addresses this through four studies among participants in the US. Across studies, our results showed that Christian nationalism was a significant and consistent predictor of anti-immigrant stereotypes, prejudice, dehumanization, and support for anti-immigrant policies. These effects were robust to inclusion of other sources of anti-immigrant attitudes, including religious fundamentalism, nationalism, and political ideology. Further, perceived threats from immigrants mediated the relationship between Christian nationalism and dehumanization of immigrants, and attitudes toward immigration policies. These findings have implications for our understanding of the relations between religious nationalism and attitudes toward immigrants and immigration policy in the US, as well as in other contexts.

对移民的态度和移民政策是美国政治中的分歧问题。这些态度受到政治取向和宗教信仰等因素的影响，宗教和保守派人士对移民和难民表现出更高的偏见，并认可更严格的移民政策。基督教民族主义是一种以美国为基督教国家为信念的意识形态，可以帮助解释宗教民族主义的身份如何影响对移民的消极态度。当前的研究通过美国参与者的四项研究解决了这一问题。在所有研究中，我们的结果表明，基督教民族主义是反移民刻板印象，偏见，非人性化和对反移民政策的支持的重要且一致的预测指标。这些影响对于包括反宗教态度，民族主义和政治意识形态在内的其他反移民态度来源具有鲁棒性。此外，来自移民的威胁被认为是基督教民族主义与移民非人性之间的关系，以及对移民政策的态度。这些发现对我们理解宗教民族主义与美国以及其他情况下对移民和移民政策的态度之间的关系具有影响。
