Rudolf Steiner, who founded the esoteric spiritual movement anthroposophy, used the concept of Ahriman to name one of two extreme forces which pull humanity away from the centering influence of Christ. Steiner associated Ahriman, the lower spirit, with materialism, science, heredity, objectivity, and soul-hardening. He thought that contemporary Christianity was subject to Ahrimanic influence, since it tended towards materialistic interpretations. Steiner predicted that Ahriman, as a supersensible Being, would incarnate into an earthly form, some little time after our present earthly existence, in fact in the third post-Christian millennium.[20]

The Opus Sanctorum Angelorum, a debated group inside the Roman Catholic Church, defines Ahriman as a “demon in the Rank of Fallen Powers”. It says his duty is to obscure human brains from the Truth of God.
