The chapter is a parody of missals that contains short prayers and songs used during Mass. For every Sunday and feast day, the “movable” parts of the Mass include an Epistle, a Gospel, and a variable number of short prayers that are used
Charles Bowen, John's friend from Notre Dame, notes his old missal has a number of such occasional prayers with headings like “To Avert Storms” and “Against Cattle-plague.” As in John’s collection, there are prayers both for and against rain, “though the ones in my Missal bear little resemblance to his.”
Kepe in mind Saint Fidgeta was published shortly John's two-year teaching stint in Winona, Minnesota, and Bowen also is quick to point out John's tender regard for the state, the so-named Land of 10,000 Lakes, in the prayer:
"...dry up the mosquito-infested dank smelly lakes of which this damned state is so proud."
Officially Minnesota is proud of its 11,842 unique lakes, from Aaron to Zumbra.
