For all of its lewd jokes and potty-mouth banter, “The Book of Mormon” commingles the profane and the sacred, dramatizing the culture shock, the physical danger and the theological doubts that infuse what one might call the missionary narrative. That narrative has been lived out for centuries by Western missionaries in a range of denominations, and it has been expressed in recent decades in a spectrum of art and literature.
“The Book of Mormon” forms part ”” admittedly a loopy and idiosyncratic part ”” of that corpus of work. Both the musical’s respect for faith-based idealism and its criticism of fundamentalist certitude have informed such films as Roland Joffé’s “The Mission” and Bruce Beresford’s “Black Robe,” novels including “The Call” by John Hersey and “The Poisonwood Bible” by Barbara Kingsolver, as well as nonfiction accounts like “The Rebbe’s Army” by Sue Fishkoff, which is not even about Christians but the Hasidic Chabad movement’s emissaries to wayward, far-flung Jews.
