Some involved in the movement avoid calling their belief system either "paganism" or "religion". Many Rodnovers refer to their belief system as an "ethnic religion", and Rodnover groups were involved in establishing the European Congress of Ethnic Religions. The usage of this term suggests that the religion is restricted to a particular ethnic group. Some practitioners regard "ethnic religion" as a term synonymous with "Native Faith", but others perceive there as being a distinction between the two terms. Laruelle has emphasised that Rodnovery "cannot necessarily be defined as a religion in the strict sense"; some adherents prefer to define it as a "spirituality" ("dukhovnost"), "wisdom" ("mudrost"), or a "philosophy" or "worldview" ("mirovozzrenie").
