evolution, modern cosmology, and physics. Mythological sources of the Goddess movement are often often considered modern reconstructions of ancient myths that predated a "patriarchal period," the Great Goddess hypothesis, influenced by the Kurgan hypothesis, and therefore very little would have been written about them. Aside from the reflection of ancient understanding of these, there are adherents who also turn to contemporary scholarship and literature such as Robert Graves' The White Goddess. Some of this work's interpretation of the Greek mythology (based mainly on James Frazer's The Golden Bough, such as the annual sacrifice of a king that represents a god) were adopted as the basis to describe the goddess' aging and rejuvenation with the seasons. The myth of Demeter and Persephone is one that has often been reinterpreted. A common claim within the Goddess movement is that myths from supposed ancient matriarchal societies were behind key elements in Christianity, particularly in the beliefs that "matriarchies fostering goddess worship influenced the attitudes of early Christians toward Mary" and that "the Catholic Church was originally matriarchal with Mary Magdalene, not Peter, as its head." The Goddess movement views devotion to female Christian figures such as the female saints as a continuation of ancient Goddess worship.

There is also the emerging agreement that the Goddess fulfills the basic functions of empowering women and fostering ethical and harmonious relationships among different peoples as well as between humans, animals, and nature. One or many? One question often asked is whether Goddess adherents believe in one Goddess or many goddesses: Is Goddess spirituality monotheistic or polytheistic? This is not an issue for many of those in the Goddess movement, whose conceptualization of divinity is more all-encompassing. The terms "the Goddess", or "Great Goddess" may appear monotheistic because the singular noun is used. However, these terms are most commonly used as code or shorthand for one or all of the following: to refer to certain types of prehistoric goddesses; to encompass all goddesses (a form of henotheism); to refer to a modern metaphoric concept of female deity; to describe a form of energy, or a process.
