For this reason, they are sometimes referred to as the "Great Goddess" and the "Great Horned God", with the adjective "great" connoting a deity that contains many other deities within their own nature.
These two deities are sometimes viewed as facets of a greater pantheistic divinity, which is regarded as an impersonal force or process rather than a personal deity.
In the 1970s, Dianic Wiccan groups developed which were devoted to a singular, monotheistic Goddess; this approach was often criticised by members of British Traditional Wiccan groups, who lambasted such Goddess monotheism as an inverted imitation of Christian theology.
As well as pantheism and duotheism, many Wiccans accept the concept of polytheism, thereby believing that there are many different deities.
An unattributed statement known as the Wiccan Rede is a popular expression of Wiccan morality, although it is not universally accepted by Wiccans.
Wicca often involves the ritual practice of magic, though it is not always necessary.
It was developed in England during the first half of the 20th century and was introduced to the public in 1954 by Gerald Gardner, a retired British civil servant.A more strictly polytheistic approach holds the various goddesses and gods to be separate and distinct entities in their own right.The Wiccan writers Janet Farrar and Gavin Bone have postulated that Wicca is becoming more polytheistic as it matures, tending to embrace a more traditionally pagan worldview.The Goddess is often portrayed as a Triple Goddess, thereby being a triadic deity comprising a Maiden goddess, a Mother goddess, and a Crone goddess, each of whom has different associations, namely virginity, fertility and wisdom.The Gods are real, not as persons, but as vehicles of power.These are traditionally viewed as the Moon Goddess and the Horned God, respectively.These deities may be regarded in a henotheistic way, as having many different divine aspects which can in turn be identified with many diverse pagan deities from different historical pantheons.Most early Wiccan groups adhered to the duotheistic worship of a Horned God of fertility and a Mother Goddess, with practitioners typically believing that these had been the ancient deities worshipped by the hunter-gatherers of the Old Stone Age, whose veneration had been passed down in secret right to the present.This theology derived from Margaret Murray's claims about the witch-cult; she claimed that whereas the cult as recorded in the Early Modern witch trials had venerated a Horned God, centuries before it had also worshipped a Mother Goddess.Gardner claimed that the names of these deities were to be kept secret within the tradition, although in 1964 they were publicly revealed to be Cernunnos and Aradia; the secret Gardnerian deity names were subsequently changed.Although different Wiccans attribute different traits to the Horned God, he is most often associated with animals and the natural world, but also with the afterlife, and he is furthermore often viewed as an ideal role model for men.
