St. Agnes is the name of the church where Adam Parrish lives and where Ronan Lynch attends Sunday mass with his brothers Declan and Matthew. Adam moved into the small apartment above St. Agnes after moving out of his parents' trailer.
The sanctuary contains a large statue of the Virgin Mary, which frequently is surrounded by candles, and the narthex has a basin of holy water. The church smells of incense.
The church also contains an organ, which Matthew used for his lessons when the building was otherwise empty.
Adam's room in the church attic has a slanted ceiling and no air conditioning.
- The priest of St. Agnes performs double duty, also servicing the church in Woodville.
