Religion and mythology differ in scope but have overlapping aspects. Both terms refer to systems of concepts that are of high importance to a certain community, making statements concerning the supernatural or sacred. Generally, mythology is considered one component or aspect of religion. Religion is the broader term: besides mythological aspects, it includes aspects of ritual, morality, theology, and mystical experience. A given mythology is almost always associated with a certain religion such as Greek mythology with Ancient Greek religion. Disconnected from its religious system, a myth may lose its immediate relevance to the community and evolve—away from sacred importance—into a legend or folktale.
Religion is a belief concerning the supernatural, sacred, or divine, and the moral codes, practices, values, and institutions associated with such belief, although some scholars, such as Durkheim, would argue that the supernatural and the divine are not aspects of all religions Religious beliefs and practices may include the following:
Some religions do not include all these features. For instance, belief in a deity is not essential to Buddhism.
The term mythology usually refers either to a system of myths or to the study of myths. However, the word "myth" itself has multiple (and some contradictory) definitions:
In regards to the study of culture and religion, these are some of the definitions scholars have used:
The relationship between religion and myth depends on what definition of "myth" one uses. By Robert Graves's definition, a religion's traditional stories are "myths" if and only if one does not belong to the religion in question. By Segal's definition, all religious stories are myths—but simply because nearly all stories are myths. By the folklorists' definition, all myths are religious (or "sacred") stories, but not all religious stories are myths: religious stories that involve the creation of the world (e.g., the stories in Genesis) are myths; however, religious stories that don't explain how things came to be in their present form (e.g., hagiographies of famous saints) are not myths.
