For British historian Robert Service, communism is a religion.

"British historian Robert Service, in Comrades: a world history of communism, goes further [than Hitchens]. For Service, communism is a religion, a "secular credo" complete with millenarian overtones (apocalypse followed by paradise), an emphasis on scriptural exegesis (each communist party "was a synod of hair-splitting political discussion") and a theory of historical inevitability that looks suspiciously like a doctrine of predestination. Marx and Engels, Service suggests, enthusiastically encouraged devotion, with the consequence that they were "treated as prophets whose every word had to be treasured"."
