Between the abolition of the grotto system in 1975 and the establishment of the internet in the mid-1990s, "The Satanic Bible" remained the primary means of propagating Satanism. During this period, a decentralized, anarchistic movement of Satanists developed that was shaped by many of the central themes that had pervaded LaVey's thought and which was expressed in "The Satanic Bible". Lewis argued that in this community, "The Satanic Bible" served as a "quasi-scripture" because these independent Satanists were able to adopt certain ideas from the book while merging them with ideas and practices drawn from elsewhere.
