The Immortal Regiment marching through Moscow (pobedarf.ru)

The idea of civil religion isn’t new. It’s origins go back to the 18 century France when it was first used by Jean-Jacques Rousseau in his theory of social contract. He coined this term to describe the moral and spiritual foundation essential for any modern society. According to Rousseau, civil religion was supposed to serve as a glue to keep the unity of the state and the increasingly secularising society by providing them with a common set of values.
