This contribution analyzes the role played by religion in today's EU party systems by adopting the concept of religiously oriented party, which rejects the binary notion of 'religious' versus 'secular' party identities, to try to understand how religion contributes to shape the preferences and policies of different types of parties. It will also adopt Ozzano's typology, including five different models of religiously oriented parties: conservative, nationalist, progressive, fundamentalist, and camp. The contribution will show the partial decline, in 21st-century Europe, of 'traditional' religiously oriented parties of the conservative type (mainly Christian Democratic ones) and the success of the new right-wing populist party family: which, although sharing an identity-driven, nationalist, and civilizational idea of Christianity, shows striking differences in the use of religious symbols and values made by the different parties.
