Yes, reason has been a part of organized religion, ever since two nudists took dietary advice from a talking snake.

Stewart’s line is a satirical jab at claims that religion is fundamentally grounded in “reason.” By reducing the Genesis creation-and-fall narrative to blunt, modern terms—“two nudists” and “dietary advice from a talking snake”—he highlights how many religious traditions begin with miraculous or mythic premises that do not conform to ordinary standards of rational evidence. The humor comes from the contrast between the lofty rhetoric of rational theology and the story’s fantastical elements. The broader point is less about disproving faith than about puncturing self-serious arguments that portray religious belief as straightforwardly rational in the same way as empirical inquiry.
