The semiotics of religion is the study and interpretation of signs in religious practices and experiences. Signs are not understood as fixed equivalences or correspondences between signifier and signified; on the contrary, they imply more complex cultural relationships. The semiotics of religion is a semiotics of culture, because religion is culture, just as communication and signification are culture. This book is the study of the communication systems and sign structures that support religious experiences, cults, rites, beliefs and practices about transcendental entities. It is the application of semiotics to religion, to systems of signs and their uses and meanings within structures of signification, with cultural elements that define a religion, its beliefs, practices, expressions and productions of meaning and processes of semiosis or semiotic ideologies with implications for the meaning of life and ways of seeing, thinking, feeling, acting and representing reality. Religionis a semiotic phenomenon because it is based on signs, representations and processes of signification and cultural construction of the world, without which there could be no religion.
