Joshua Graham is a walking quote engine. I've also seen the ones about light in the darkness and following the path floating around.

What's great about his character is he's clearly a violent maniac who had some kind of ego-death after getting tossed in the Grand Canyon and despite hating Caesar, he's doing the same thing Caesar did. He's uniting these tribal people together against common enemies through militancy and a united cultural framework. Caesar did it through Roman cosplaying and Graham's doing it through scifi Mormonism.
