The novel follows him across the Atacama nitrate pampa in search of Magalena Mercado, a prostitute at a nitrate camp who is devoted to the Virgin, whom he wants as his Mary Magdalene. His messianic calling, his loneliness and his carnal longing drive the same journey, so the quest is both holy mission and courtship.
The novel treats the preacher's desire for a companion and his spiritual vocation as the same drive, not as temptation versus faith. He frames his search for a woman in scriptural terms, and his lust and his piety each borrow the other's language. The devout prostitute mirrors him, keeping her faith inside a trade the church condemns and suggesting that sanctity is lived through the body, not above it.
A self-appointed messiah's authority lasts only as long as the audience grants it. The pampa's workers, isolated and poor, supply the preacher with followers, food and attention in exchange for consolation, advice and spectacle.
The book tells a sincere man's spiritual quest through picaresque humor. It stages his sermons, sayings and failed miracles as comedy without mocking the faith behind them. This lets the reader laugh at the prophet's absurdity while still taking his suffering and the workers' need for hope seriously.
