The review is a response to the publication of T. V. Itskovich’s monograph “Genre system of the religious style”. The author of the book presents an original view on the functional religious style as a system of genres and gives its multidimensional description. The relevance of the research is justified by the need for a comprehensive linguistic study of the religious style as part of the paradigm of functional varieties of the modern Russian literary language and the classification of genres of the religious style on a single basis. In the monograph, its author, basing on an integrated approach which combines communicative-pragmatic and categorical-textual aspects of the study of religious texts, taking into account the cultural-historical and textual genesis of religious genres, establishes the constructive principle of the religious style, gives a scientific description of the system of religious genres and its proto-genre basis, reveals the compositional-thematic and speech originality of religious genre types and their varieties as well as the core and periphery of the genre field of religious style. The study is based on the texts of the liturgical and non-liturgical spheres of Orthodox religious communication in Russian and Church Slavonic, selected by the author on the basis of the tradition of their use in the religious activities of the Church and the individual as well as the frequency of their use in modern religious communication.
