The term can be defined broadly, to encompass the faith traditions outside the Abrahamic monotheistic group of Judaism, Christianity, and Islam.Fact: date=September 2008 The group so defined includes many of the Eastern religions, Native American religions and mythologies, as well as non-Abrahamic ethnic religions in general. More narrow definitions will not include any of the world religions and restrict the term to local or rural currents not organized as civil religions. 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, mushrik and kafir (كافر) 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 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).

Pagan

The term pagan is from the Latin paganus, an adjective originally meaning "rural", "rustic" or "of the country." As a noun, paganus was used to mean "country dweller, villager." The semantic development of post-classical Latin paganus in the sense "non-Christian, heathen" is unclear. The dating of this sense is controversial, but the 4th century seems most plausible. An earlier example has been suggested in Tertullian De Corona Militis xi, "Apud hunc Christum tam miles est paganus fidelis quam paganus est miles infidelis," but here the word paganus may be interpreted in the sense "civilian" rather than "heathen". There are three main explanations of the development:

• (i) The older sense of classical Latin pāgānus is "of the country, rustic" (also as noun). It has been argued that the transferred use reflects the fact that the ancient idolatry lingered on in the rural villages and hamlets after Christianity had been generally accepted in the towns and cities of the Roman Empire; cf. Orosius Histories 1. Prol. "Ex locorum agrestium compitis et pagis pagani vocantur." From its earliest beginnings, Christianity spread much more quickly in major urban areas (like Antioch, Alexandria, Corinth, Rome) than in the countryside (in fact, the early church was almost entirely urban), and soon the word for "country dweller" became synonymous with someone who was "not a Christian," giving rise to the modern meaning of "Pagan." This may, in part, have had to do with the closeness to nature of rural people, who may have been more resistant to the new ideas of Christianity than those who lived in major urban centers and were cut off from the cycles of nature and the forms of spirituality associated with them. However, it may have also resulted from early Christian missionaries focusing their efforts within major population centers (e.g., St. Paul), rather than throughout an expansive, yet sparsely populated, countryside (hence, the Latin term suggesting "uneducated country folk") until a bit later on.
• (ii) The more common meaning of classical Latin pāgānus is "civilian, non-militant" (adjective and noun). Christians called themselves mīlitēs, "enrolled soldiers" of Christ, members of his militant church, and applied to non-Christians the term applied by soldiers to all who were "not enrolled in the army".
• (iii) The sense "heathen" arose from an interpretation of paganus as denoting a person who was outside a particular group or community, hence "not of the city" or "rural"; cf. Orosius Histories 1. Prol. "ui alieni a civitate dei..pagani vocantur." See C. Mohrmann, Vigiliae Christianae 6 (1952) 9ff.
