So this is basically Scientology...
The similarities are striking. Scientology has a shadowy founder who disappeared for several years, before it was announced that he left his earthly body in order to move forward on what they call "the bridge" (not the ladder). His second in command takes over and moves quickly to increase the profile and wealth of the organization.
And that contraption we see Eddie and Sarah wearing in the 2nd episode looks an awful lot like an e-meter, which is used heavily in Scientology.
The one thing Meyerism doesn't yet have is the celebrity aspect of Scientology. No Tom Cruises yet, but I expect Cal will begin to recruit them to spread his message.
Scientologists are notoriously touchy about how their "religion" is portrayed. I'm guessing they're not too happy about how close Meyerism is to some of their core beliefs.
