The political-ideological position favoring native-born inhabitants of a country over immigrants, generally accompanied by suspicion of specific immigrant groups perceived as cultural, economic, or political threats. Historically prominent in mid-nineteenth-century American politics (the American Party / Know-Nothing movement of the 1840s-1850s opposed primarily Irish-Catholic immigration); recurrent in the late nineteenth century (Chinese Exclusion Act, 1882), the early twentieth (Immigration Acts of 1921 and 1924), and the early twenty-first (post-9/11 immigration politics; the 2016-onward debates). The biblical assessment is, again, careful. Scripture commands kindness to the resident alien (Lev 19:33-34; Deut 10:18-19), founds Israel’s own identity in its memory of having been strangers in Egypt (Ex 22:21), and frames the eschatological people of God as drawn from every nation. It also affirms the legitimate prudential authority of the magistrate to regulate borders, set immigration policy, and prioritize the formation of the people God has placed in his charge. The Christian rejects the hard nativism that treats the alien as enemy AND the open-borders idealism that abdicates the magistrate’s duty to order the polity.
