I don't have a copy of it near at hand, so I can't tell you exactly which chapter it is, but in Vikram Seth's The Golden Gate there is a chapter in which one of the main characters >!attends an anti-nuke protest, and at the protest a priest gets up and makes an impassioned speech that just takes my breath away every time I read it.!< (You said no spoilers, although the chapter I'm talking about here is not key to moving the book's plot forward so there's no harm in peeking).
