In Christianity, morally ambivalent daimōn were replaced by demons, forces of evil only striving for corruption. [7] Such demons are not the Greek intermediary spirits, but hostile entities, already known in Iranian beliefs. [8] While daimons were considered as both potentially benevolent or malevolent, Origen argued against Celsus that daimons are exclusively evil entities, supporting the later idea of (evil) demons. According to Origen's cosmology, increasing corruption and evil within the soul, the more estranged the soul gets from God. Therefore, Origen opined that the most evil demons are located underground. Besides the fallen angels known from Christian scriptures, Origen talks about Greek daemons, like nature spirits and giants. These creatures were thought to inhabit nature or air and nourish from pagan sacrifices roaming the earth. However, there is no functional difference between the spirits of the underworld and of earth, since both have fallen from perfection into the material world. Origen sums them up as fallen angels and thus equal to demons. [108] David S.

The Bundahishn offers an overview about the creation of demons. The text explains that Ahura Mazda and Ahriman existed before the material world, one in light and the other in the abyss of darkness. When Ahriman assaulted Ahura Mazda, Ahura Mazda created a world as a battle place and Ahriman could be defeated. The first beings created by Ahura Mazda were the six Amesha Spenta, whereupon Ahriman counters by creating six daevas. The demons are not tempted but directly created by the principle of evil. According to the Bundahishn, the demons revive Ahriman, whereby calling him their father: [68] Properly measuring and pouring liquid insecticides can be easy with these step-by-step instructions.
