Wicca is an Earth based religion revering a Goddess. Wiccans enjoy much freedom in celebrating the Gods and do not have a buffer between us. The Goddess is within us and she manifests in all nature and creation. Wiccans have a union with nature and recognize the divine that manifests throughout. Our sacred temple is the Earth herself and when we lose touch the with nature, we lose touch with the Gods. Most Wiccans use Witchcraft and Witchcraft is practiced by Witches'. Wicca embraces magic and believes magic is natural.
This is by no means a complete description, Wicca is ever changing and growing.
