German sociologist Hartmut Rosa has developed an integral resonance theory, which is a theory of our relationship to the world. This theory has aroused much interest in recent years not only among sociologists but also among representatives of other humanities and social sciences, including representatives of the science of religion. Therefore, the author considers it worth discussing. The article deals with religion and nature in light of Rosa’s theory. Rosa understands religion and nature as two of the main axes and areas of man’s search for vertical resonance in modernity. In the section devoted to religion, the author presents Rosa’s view that the essence of religion is man’s need for a response. In light of resonance theory, the author examines phenomena such as prayer, worship, religious rites, certain holidays (Christmas), and sin. Schleiermacher, Buber, Gerhardt, Luther and Camus are singled out as particularly relevant thinkers and creators. On this basis, he discusses existential violence, which stems from the need for resonance and the rejection of alienation as its opposite. The section devoted to nature is mainly focused on the problems that hinder modern man in their quest to fulfil their longing for resonance with nature. The author explains Rosa’s thesis that the ecological crisis is, at its core and origin, an existential and cultural crisis and not a crisis of resources. The author draws conclusions concerning the importance of religion and modern man’s fear of the loss of resonance.
