Explanation:
The given poem "Church Matters" is a poem about a woman getting the Holy Communion and how the act is done so casually. The poem is written in short lines, though without the use of any punctuation.
The woman was praying and then got communion, which is a reference to the flesh and blood of Christ as His sacrifice for the sins of mankind. But aside from the ritualistic element of the actions done by the woman, the motions seemed to be done without much thought, as if it is done out of necessity rather than religious belief.
Grover tells Percy that, when the Furies found them on the bus, they were asking, "where is it?" rather than "where is he?" It seems they are looking for an object, rather than a human.
