Religious cognition is considered as one of the types of cognition that coexist in the overall cognitive process. The author identifies the qualitative and defining properties of religious cognition: the admissibility and priority of extra-logical means of cognition, traditionalism, authoritarianism, symbolism, and polyvariant determinism. On this basis, an extended interpretation of the title concept of the work is proposed. Religious knowledge in a narrow sense is the understanding of sacred objects and sacred history, with the obligatory reliance on the idea of supernatural reality. Religious cognition in a broad sense is the comprehension of other realities, which is carried out using the same set of logical means, through the procedures of sacralization, canonization, and giving symbolic meaning to objects. This interpretation also significantly expands the scope of cognitive processes that can be attributed to religious cognition. The paper presents examples of manifestations of religious knowledge in a broad sense.
