The objective of this research is to put forward, systematically and interdisciplinary, the representative elements that facilitate the understanding of religion as a language, whereby a particular community elaborates and fully communicates its experience of God, as a significant contribution to the construction of the theological reflection of Latin American Religious Pluralism, through the use of its methods and tools of interpretation and analysis; since religion and language share a similar structure (or set of structures), whose objective is to help collectivities, and ultimately, people to become human, that is, they are indicators of humanity and humanization. It was carried out through the examination of some constitutive aspects of language, as a vehicle for communicating the tangible and intangible contents derived from the faith; Next, the Biblical and systematic foundations of Revelation are specified as message and reference; and at the end, it provides some contributions to the Theology of religious pluralism inferred from the functional relationship between language and religion. Throughout the text, doors open to new proposals both in spirituality and in various fields of theology, with a pluralist approach, in response to the search for meaning that religion will give in the future, beyond its assumptions and its limits, as well as for all the manifestations of the human response towards the always-active presence of God.
