The article deals with the interpretation of keywords as indicators of registering intertextual properties in English New Testament texts. The notion of “intertextuality” is represented in terms of three approaches: philosophical-poststructuralist, philological, and genre-textual is considered to be a complex interdisciplinary phenomenon and is characterised as a system-textual and prototypical category, with an emphasis on the typological properties of textuality. It has been proved that in order to register the intertextuality in English New Testament Texts, the notions of “keywords” and “life cycle” as indicators of actualization (active vocabulary) or deactualization (passive vocabulary) of tokens represented in a specific type and kind of discourse were introduced. AntConc corpus manager as an artificial intelligence programme, which is a free and multifunctional tool for statistical research of texts of different languages of various discourses (Dr Laurence Anthony), helped to establish the following most frequent keywords of intertextuality in English New Testament texts: God (1372), Jesus (989), Man (908), Lord (728), Christ (571), Will (555), Son (422), Father (370), Spirit (299), Heaven (256).
