The article examines the peculiarities of state-church relations that are formed in the process of legitimizing civil society. It is substantiated that the 21st century, like the last 20th century, forces us to search for a new format of state-church relations in the context of international relations, modern globalization challenges, and the development of the latest communication and information space.
