I think the title character is the arsonist who is burning to cleanse. Heat is a source to sterelize, and he sees evil in the world around him. He burns the town to cleanse it of the evils he perceives. Fire is also often associated with hell, so it has double meaning here. The second verse it the character reeling in his own guilt both at his actions and just in general seeing evil in everything, especially himself.
Ultimately it may be a theme about people riding the fire and brimstone mantra too much, thus the emphasis on churches. I have noticed a lot of pro spiritual/christian themes throughout JJ's lyrics (I am not a religious type myself, but I respect and appreciate those who are), and much anti organized religious themes too. This may be one that explores the damage done in the FnB routine and creates an unintended monster.
