    • manichean Of or pertaining to the Manicheans.
    • n manichean One of a religious body, adherents of Mani, Manes, or Manichæus, a native of Persia or some neighboring country, in the third century. Its doctrines and features were derived from Gnostic, Buddhistic, Zoroastrian, and various other sources. These it attempted to combine with Christianity, and it is generally classed among Gnostic sects. Its theology was dualistic, representing the conflict between light and darkness, and including belief in the inherent evil of matter. Its morality was professedly ascetic, but profligacy of life and cruel or immoral ceremonial were generally attributed to it in both its earlier and its later forms. It had an organized priesthood, and recognized a distinction between its esoteric class (the “elect” or “perfect”) and the “hearers.” It originated in Persia, but soon extended into the Roman empire, and existed as late as the seventh century. The Paulicians, Albigenses. Catharists, etc., developed it into new forms, retaining many of its features, and hence were styled “New Manicheans.” The title Manichean, or New Manichean, was an epithet used opprobriously in the controversies of the middle ages.
