 Jarrow 's script was " almost entirely based on Hubbard 's own writings and the church 's literature " , though Jarrow was also influenced by critical journalistic accounts . He also drew on the " awkward woodenness of Christmas pageants — the fact that children are often made to say large words that don 't sound natural coming out of their mouths . " Timbers said they chose to stick to Church of Scientology primary source material for background on the script because " We thought that the best way to satirize the Church of Scientology was to let the Church speak for itself . " During production , the creative team worked with cast members to educate them about the play 's background . " Kids shouldn 't just be saying things that they don 't understand . That 's what we 're criticizing ... people who just parrot behavior and language . We wanted to have an honest conversation with them , " Jarrow said . The published version of the script says that the musical should not be performed by adults ; Jarrow said adults are " too jaded " , and would not be able to portray the " unwinking satire " of the piece .
