Despite predictions that urbanization, economic development and globalization would lead to the recession of religion from public life, populations around the world continue to be highly religious. This pattern holds in most parts of the Global South and also in some advanced industrial democracies in the North, including in the United States. In grappling with the influence (or lack thereof) of religion on political life, a growing body of literature pays attention to how clergy–congregant communication might shape listeners’ political attitudes and behaviors. Considerable debate remains as to whether clergy–congregant communication is likely to change political attitudes and behavior, but there is a greater consensus around the idea that exposure to religious communication can at the very least prime (that is, increase the salience of) certain considerations that in turn affect how people evaluate political issues and whether they participate in politics. Religious communication is more likely to exert a persuasive and a priming influence among those already inclined to select into the communication and when the source of the communication is credible. More research is needed on the duration of religious primes and on the effects of religious communication in different political and social contexts around the world.
