The book tells about the largest Protestant religious organization in modern Russia - Jehovah's Witnesses. The author, a religious scholar with 25 years of experience who is not a Jehovah's Witness, successfully defended his doctoral dissertation in 2002 on the evolution of the ideology and activities of Jehovah's Witnesses in Russia and seeks to objectively answer the questions: are Jehovah's Witnesses a sect, can they be considered a traditional religious organization for Russia, what are the prospects for improving relations between Jehovah's Witnesses and the state. Based on the results of sociological studies conducted among believers in Moscow, the author analyzes the influence of the religious views of Jehovah's Witnesses on their family relationships. The publication is designed for civil servants, including those involved in relations with religious associations, students and teachers, as well as everyone interested in the religious situation in Russia.
