When used to refer to Wicca, it is indicitive of the fact that parts of Wicca may have come from pre-christian times. It would be more correct to say that Witchcraft is the Old Religion, even if one does not count Witchcraft as a religion.
A term used by some to refer to non-Wiccan Witchcraft. A somewhat problematic generality, as there are many "Old Religions," as well as many forms of witchcraft from various cultures.
Another name for Wicca. Also, Old Path or Old Ways.
