The article deals with the attitude to Protestantism in the post-soviet Russia. Formation of Protestantism in Russia can be considered in the present paper. Thus, the purposes of this research are to examine formation of Protestantism in Russia, to analyze attitude of Russians to Protestantism and to identify its reasons. The author’s periodization of Protestantism formation in Russia is proposed. This periodization is based on 3 criteria: types of Protestants activities at each stage; the government’s attitude to it; its functions. It is shown that the establishment of the Russian Protestantism version took five basic steps. In modern Russia, Protestantism has its own history, values it gained its traditions, and it has its own distinctive character. Protestant churches are ready to actively participate in solving the pressing issues facing the people of the country. The authors suggest that the most authoritative of them can and should acquire the status of social partners of state institutions and significantly contribute to the spiritual and moral education of young people, to overcoming child homelessness and neglect, to family strengthening, to improvement of moral atmosphere in society and to the formation of high standards of business, economic and work ethic. The positive development of this process and its dynamics are largely dependent on Russian Protestants consolidation and on their willingness and ability to develop and strengthen interfaith relations and cooperation. According to the article, the attitude of most Russians to Protestantism is largely negative, although most of them have friends or acquaintances among the followers of this religion. The reasons for this are stereotypes in the public opinion of Russians: about the church itself (simplification of ceremonies, of the Bible, of the decoration of the church), and about the personal qualities of the congregation (the rejection of community service and charity, lack of citizenship).
