Religion and mythology differ in scope but have overlapping aspects. Both are 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. There is a complex relationship between recital of myths and enactment of rituals. Introduction 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 the Book of Genesis) are myths; however, some religious stories that don't explain how things came to be in their present form (e.g., hagiographies of famous saints) are not myths. Generally, mythology is the main component of religion alongside ritual. For example, in the early modern period, distinguished Christian theologians developed elaborated witch mythologies which contributed to the intensification of witch trials. The Oxford Companion to World Mythology provides the following summary and examples:Religious stories are "holy scripture" to believers—narratives used to support, explain, or justify a particular system's rituals, theology, and ethics—and are myths to people of other cultures or belief systems. […] It is difficult to believe that the Buddha was conceived in a dream by a white elephant, so we call that story a myth as well. But, of course, stories such as the parting of the Sea of Reeds for the fleeing Hebrews, Muhammad's Night Journey, and the dead Jesus rising from the tomb are just as clearly irrational narratives to which a Hindu or a Buddhist might understandably apply the word "myth". All of these stories are definable as myths because they contain events that contradict both our intellectual and physical experience of reality. Most definitions
