Pagan

Pagan  n :  a person who is not a Jew, Muslim or Christian.  it is someone who doesn't conform to mainstream religions but prefers to follow a more polytheistic religion.  Often the word is used in a derogative manner to describe someone who has no religion, a non-Christian, a hedonist, heathen or a Neo-Pagan.  The term is also used derogatively to describe idolaters and persons who worship false gods.

However, the term has assumed a new meaning among the practitioners of witchcraft and magic.  This is especially true of the New Pagans who dedicate themselves to the revival of the Old Religion (an expression used by contemporary Wiccan devotees to describe witchcraft); and to re-establish the worship of nature and the lunar godess.
