Which political entities are “Friendly” to religion? The interplay of entity, identity congruence, and Christian nationalism

How do Americans perceive the orientation of political entities toward religion? Building on group identity theories and burgeoning Christian nationalism research, I theorize Americans' perceptions of friendliness, neutrality, or unfriendliness toward religion will be contingent on the interplay between the specific entity, “identity congruence” (how partisan and ideological identities correspond to the partisan character of the entity), and Christian nationalism. Analyses of data from a large, nationally representative sample of Americans support my expectations. Both Christian nationalism and congruence on political identities predict how Americans perceive the posture of the Democratic Party, Republican Party, and Supreme Court toward religion. Yet associations differ depending on whether friendliness to religion challenges the entity's legitimacy (e.g., the Supreme Court). Interactions also show the influence of Christian nationalism and political identities on perceptions of friendliness are contingent on one another and the entity. Findings reveal how religious evaluations reflect group interests in complex ways.
