This chapter begins with defining the key terms of religion and discourse, presenting how different approaches to language have influenced the understanding of religious experience and vice versa. A definition of discourse is provided whichfocuses on functions, embodied cognition, and emergence. Religion and spiritual experience have been described from a variety ofperspectives with attempts to understand language with various perspectives (functional, embodied cognition, and emergence) applied to religious language and talk about religious experience. Finally, the emergence and influence of mediatisation and secularisation are discussed in terms of their effects on religious believers.
