The religion we see in Gilead isn't about sin, but sin sure does haunt the novel.
John Ames is a Christian preacher in a small-town church. You'd expect him to discuss sin, and he does, but it's not his focus. He's not a fire-and-brimstone kind of preacher. He's concerned with what's necessary in a sinful world: grace, forgiveness, solidarity, and love. He has no illusions about how destructive sin can be to lives and relationships, but he doesn't despair or wags his finger. Instead, he tries to help, and he does that partly by trying to see the sacredness within everyone.
