Series co-creators Trey Parker and Matt Stone described the production of "Go God Go" and "Go God Go XII" as "painful", mainly because of how it deals with atheism. They spoke about how difficult it is to make such a subject humorous without seeming "preachy". For a time, the episode actually did end up feeling "preachy" because too many ideas and statements were present. To rectify this, large portions of the episodes that more reflected Parker and Stone's personal opinions were removed and replaced with less serious material.
