Divine Boundaries: How Religion Shapes Citizens’ Attitudes Toward Immigrants

Abstract

How does religion affect one’s attitudes toward immigrants? Scholars have shown that members of minor religious groups are less anti-immigrant than members of majority affiliations and that Evangelical Protestants are particularly hostile. Other scholars have demonstrated that increased religiosity reduces immigrant animus. Here, we argue that religion affects immigration attitudes via a distinct religiously informed interpretation of America’s national identity, which we call Christian nationalism. Christian nationalists believe that America has a divinely inspired mission and link its success to God’s favor. Using social identity complexity theory, we argue that citizens who ascribe to this worldview should be least tolerant of those they perceive as symbolic threats to American national identity. We assess this claim using the 2006 Pew Immigration Attitudes Survey and the 2008 Cooperative Congressional Election Survey. Christian nationalism is a robust determinant of immigrant animus, whereas religious affiliation only affects immigrant animus when Christian nationalism is excluded.
