The ideas of modern man about the sacred are considered, which today is understood not only as metaphysical, religious, but increasingly characterizes everyday aspects of life that are of particular importance for the individual and society. The purpose of the article is to study the idea of the sacred in modern man, society in the conditions of secularization. The tasks are to analyze the views of researchers regarding the transformation of the concept of the sacred; find out the influence of the modern cultural situation on this process; to consider the peculiarities of experiencing the sacred as secular. The transformation of the idea of the sacred means spreading the understanding of it, which expresses the significant values of a person, society, phenomena, objects, ideas, symbols, relations of a secular nature. This expanded understanding of the sacred, initiated by E. Durkheim, is shared and developed by a part of modern researchers. The views of scientists regarding the change in the idea of the sacred are analyzed. It is proved that such beliefs are established in connection with the deepening of secularization, which means the reduction of the social influence of religion and the related understanding of the sacred, the spread of the values of individualism, consumerism, hedonism, the priority of the material over the spiritual, the immanent over the transcendent, value relativism. It turns out that the modern economic and cultural situation leads to a decrease in the distance between the sacred and the profane, the sacralization of everyday things, and the finding of meaning in everyday life. It is noted that the transformation of the idea of the sacred from a metaphysical, religious to a broad interpretation that assigns an increasingly significant role to secular values, practices, and things leads to an increase in human dependence on the social, material world, psychological experiences and the deprivation of life of a deeper meaning, mystery, and completeness. In modern society, there are various ideas about the sacred. There are preserved views on it as something that relates to the metaphysical, divine dimension of being and is synonymous with the holy, inherent primarily to people who associate themselves with a religious tradition. Although various spiritual trends, practices, and their adherents have their own characteristics, this metaphysical sacred appears to be the complete opposite of the profane, giving a person a sense of something greater than himself, forming a holistic picture of the world, directing his activities, giving meaning to life in a qualitatively different dimension and perspective. With the development of secularization, there is a decrease in the influence of religion in society and the idea of the sacred formed by it, there is a demarcation of the concepts of the sacred and religion, which were previously considered identical. An expanded understanding of the sacred strengthens - that which means objects, symbols, things, and practices that are important for man and society, reflects everyday interests, ideas, and practices, is more dependent on the individual than on the influence of tradition and the church.
