elaborate dualistic cosmology describing the struggle between a good, spiritual world of light, and an evil, material world of darkness. Through an ongoing process that takes place in human history, light is gradually removed from the world of matter and returned to the world of light, whence it came. Its beliefs were based on local Mesopotamian religious movements and Gnosticism. and other Abrahamic religions The dualism between God and Creation has existed as a central belief in multiple historical sects and traditions of Christianity, including Marcionism, Catharism, Paulicianism, and other forms of Gnostic Christianity. Christian dualism refers to the belief that God and creation are distinct, but interrelated through an indivisible bond. However, Gnosticism is a diverse, syncretistic religious movement consisting of various belief systems generally united in a belief in a distinction between a supreme, transcendent God and a blind, evil demiurge responsible for creating the material universe, thereby trapping the divine spark within matter. Gnosticism is not limited to Christianity, and also incorporates beliefs from other Abrahamic traditions, such as early Jewish sects. In sects like the Cathars and the Paulicians, this is a dualism between the material world, created by an evil god, and a moral god. Historians divide Christian dualism into absolute dualism, which held that the good and evil gods were equally powerful, and mitigated dualism, which held that material evil was subordinate to the spiritual good. The belief, by Christian theologians who adhere to a libertarian or compatibilist view of free will, that free will separates humankind from God has also been characterized as a form of dualism. The theologian Leroy Stephens Rouner compares the dualism of Christianity with the dualism that exists in Zoroastrianism and the Samkhya tradition of Hinduism. The theological use of the word dualism dates back to 1700, in a book that describes the dualism between good and evil. The tolerance of dualism ranges widely among the different Christian traditions. As a monotheistic religion, the conflict between dualism and monism has existed in Christianity since its inception. The 1912 Catholic Encyclopedia describes that, in the Catholic Church, "the dualistic hypothesis of an eternal world existing side by side with God was of course rejected" by the thirteenth century, but mind–body dualism was not. The problem of evil is difficult to reconcile with absolute monism, and has prompted some Christian sects to veer towards dualism. Gnostic forms of Christianity were more
