A heathen, generally, is one whose belief system lies outside the boundaries of the Judeo-Christian religious view.

According to The Devil's Dictionary: "HEATHEN, n. A benighted creature who has the folly to worship something that he can see and feel. According to Professor Howison, of the California State University, Hebrews are heathens."

You wrote Heathen with the first letter in caps, thus I believe it is a name. If not a name and the caps is a typo, then: Christianity began as an urban religion; people in rural districts continued to worship older gods. The Latin word for countrymen was paganus—hence, of course, pagan; the Germanic tongues has a similar word, khaithanaz, "dwelling in the heath" (wilderness)—hence "heathen." Bye.

A Heathen is someone who follows the pre-Christian religion of one of the Germanic peoples, such as the Norse, Saxons or the English. A polytheistic religion, Heathenism focuses on "right action", rather than obscure concepts such as salvation. Heathens typically revere their ancestors and the Gods, as well as other spirits. The Gods revered by Heathens are best known by the names given them in the Norse Sagas: Odin, Thor, Frigga, Freya, Tyr, Heimdall, and many others. The ethical code follwed by many Heathens is summarized in the "Nine Noble Virtues", which are: Courage, Truth Honour, Fidelity, Hospitality, Discipline, Industriousness, Self-Reliance, and Perseverance. In contrast to many other styles of modern paganism, Heathens are not generally pacifistic in any way. There are many Heathens serving in the military or the police force, and are honoured for it within their religious communities. In addition, many civillian Heathens own weapons are well-versed in their use. Pacifism and turning the other cheek have no place in Heathenism, but standing up for one's community, friends and family and nation do. Heathens are in general the antithesis of typical "fluffy bunny" pagans, espousing the values of ancient Germanic warriors, rather than the values associated with pacifism and political correctness. It is for those reasons, and the attention to historical practice that some Heathens don't call themselves "pagans" at all, preferring to maintain a very distinct identity from other polytheistic faiths.

A heathen is someone who isn't christian and has never been baptised. More generally, it refers to atheists.

1) "Noun heathen (plural heathen or heathens) 1. A person who does not follow an Abrahamic religion; a pagan. 2. (by extension) An uncultured or uncivilized person, philistine. 3. Self-designation of some adherents of neo-paganism." Source and further information: http://en.wiktionary.org/wiki/heathen "Heathen or Heathenry may refer to: 1. A pagan 2. A modern adherent of Germanic neopaganism." Source and further information: http://en.wikipedia.org/wiki/Heathen_(disambiguation%29 2) "Paganism (from Latin paganus, meaning "country dweller", "rustic") is a word with several different meanings. In its broadest definition, it is a blanket term used to refer to various polytheistic religions. The group so defined includes most of the Eastern religions, Native American religions and mythologies, as well as non-Abrahamic folk religions in general. More narrow definitions do not include any of the current world religions and restrict the term to local or rural currents, particularly those not organized as civil religions. Other definitions focus on the ancient, largely extinct, polytheistic religious traditions of Greece, Rome, and other classical civilizations. Characteristic of pagan traditions is the absence of proselytism and the presence of a living mythology which explains religious practice. The term "pagan" is a Christian adaptation of the "gentile" of Judaism, and as such has an inherent Abrahamic bias, and pejorative connotations among Western monotheists, comparable to heathen, and infidel also known as kafir (كافر) and mushrik in Islam. For this reason, ethnologists avoid the term "paganism," with its uncertain and varied meanings, in referring to traditional or historic faiths, preferring more precise categories such as polytheism, shamanism, pantheism, or animism; however others[who?] criticise the use of these terms, claiming that these are only aspects that different faiths may share and do not denote the religions themselves. Since the later 20th century, "Pagan" or "Paganism" has become widely used as a self-designation by adherents of Neopaganism. As such, various modern scholars have begun to apply the term to three separate groups of faiths: Historical Polytheism (such as Celtic polytheism and Norse paganism), Folk/ethnic/Indigenous religions (such as Chinese folk religion and African traditional religion), and Neo-paganism (such as Wicca and Germanic Neopaganism)."

Precursor movements appeared in the early 20th century in Germany and Austria. A second wave of revival began in the early 1970s. Attitude and focus of adherents may vary considerably, from strictly historical polytheistic reconstructionism to syncretist (eclectic), pragmatic psychologist, occult or mysticist approaches. Germanic Neopagan organizations cover a wide spectrum of belief and ideals." Source and further information: http://en.wikipedia.org/wiki/Germanic_Neopaganism
