Christian dualism is largely based on Platonic Dualism (See: Neoplatonism and Christianity). There is also a personal dualism in Christianity with a soul-body distinction based on the idea of an immaterial Christian soul. Duotheism, bitheism, ditheism When used with regards to multiple gods, dualism may refer to duotheism, bitheism, or ditheism. Although ditheism/bitheism imply moral dualism, they are not equivalent: ditheism/bitheism implies (at least) two gods, while moral dualism does not necessarily imply theism (theos = god) at all. Both bitheism and ditheism imply a belief in two equally powerful gods with complementary or antonymous properties; however, while bitheism implies harmony, ditheism implies rivalry and opposition, such as between good and evil, bright and dark, or summer and winter. For example, a ditheistic system would be one in which one god is creative, the other is destructive (cf. theodicy). In the original conception of Zoroastrianism, for example, Ahura Mazda was the spirit of ultimate good, while Ahriman (Angra Mainyu) was the spirit of ultimate evil. In a bitheistic system, by contrast, where the two deities are not in conflict or opposition, one could be male and the other female (cf. duotheism). One well-known example of a bitheistic or duotheistic theology based on gender polarity is found in the neopagan religion of Wicca. In Wicca, dualism is represented in the belief of a god and a goddess as a dual partnership in ruling the universe. This is centered on the worship of a divine couple, the Moon Goddess and the Horned God, who are regarded as lovers. However, there is also a ditheistic theme within traditional Wicca, as the Horned God has dual aspects of bright and dark - relating to day/night, summer/winter - expressed as the Oak King and the Holly King, who in Wiccan myth and ritual are said to engage in battle twice a year for the hand of the Goddess, resulting in the changing seasons. (Within Wicca, bright and dark do not correspond to notions of "good" and "evil" but are aspects of the natural world, much like yin and yang in Taoism.) Radical and mitigated dualism Radical Dualism – or absolute Dualism which posits two co-equal divine forces. Manichaeism conceives of two previously coexistent realms of light and darkness which become embroiled in conflict, owing to the chaotic actions of the latter. Subsequently, certain elements of the light became entrapped within darkness; the purpose of material
