This paper explores the concept of orthodoxy. This has been one of the most intensely debated topics in Philosophy of Religion and also in the Theology of the main religions. Thus, starting from Raimon Panikkar's philosophical approaches, this paper intends to characterize synthetically orthodoxy within religious experience, its triple relationship with theophany, myth and rite, and from the philosophical approach. Finally, this paper reflects on how orthodoxy became religious populism and it forgot that the believer needs freedom and plurality of meanings to experience the divine and his own belief.
