 ::I would say spirituality/religion is most certainly a subsection of Society/Culture, given that a person's level of spirituality and what religion they follow are almost exclusively a product of the society/culture to which they are exposed (either by themselves or others); and the religion and spirituality of a group is often a defining feature of their culture or society. It would be fairly difficult for a person who has never been exposed to Catholicism to be a Catholic.
