Meyerism , or the Meyerist Movement, is the fictional religion at the basis of the Hulu Original TV series The Path.
Meyerism is elaborated in the (fictional) book The Ladder by the cult's leader, Dr. Steven Meyer.
A Vanity Fair analysis of the show's first episode described Meyerism as "inspired by a grab bag of religious practices and cult beliefs". The show's creator, Jessica Goldberg, specifically refutes comparisons to Scientology although many scenes, doctrines, and elements of the show draw on Scientology, even down to scenes depicting a device resembling an e-meter being used. The show's name was changed early on in development from The Way due to its closeness to real-life ministry and alleged cult, The Way International to avoid legal fallout.
Hugh Dancy, who plays the group's acting leader, gives further detail: "Meyerism was founded by Dr. Steven Meyer in Cusco, Peru, after he saw a vision of a burning ladder at the top of a mountain. When he ascended the ladder, he saw two visions: a catastrophic world after a global disaster, and a beautiful garden."
