Who is Where I Live: Father Nicholson from Welcome to the Monkey House and what is their importance?

Father Nicholson is the tender of the Church garden and a Barnstable resident. He seems like a moral center in the town. Though only mentioned twice, his words close the story. His description of the Barnstable residents ("We're Druids.") is the last image of the story. His church garden is also highly praised. He seems like the narrator's ideal sort of Barnstable inhabitant.
