"Guilt upon the conscience, like rust upon iron, both defiles and consumes it, gnawing and creeping into it, as that does which at last eats out the very heart and substance of the metal"
About this Quote
Souths intent is pastoral and prosecutorial at once. As a Restoration-era Anglican divine famed for his combative sermons, he was speaking to an England newly reacquainted with public vice and private compromise after civil war, regicide, and political whiplash. In that climate, conscience could be treated as a negotiable accessory. South refuses that luxury. He casts guilt as self-consuming: it "gnaws" and "creeps", verbs that make sin sound less like a single choice and more like an infestation you either halt or host.
The subtext is a warning against delay. Rust spreads in quiet conditions; so does moral rot when it is rationalized, hidden, or left "between you and God". South also subtly rejects cheap absolution. If guilt has eaten into the "heart and substance", repair is harder than a quick apology; it demands confession, restitution, and grace before the damage becomes structural. The metaphor makes conscience feel physical, and thats the point: you cant pretend youre fine when youre already flaking.
