The marriage cannot go on: I declare the existence of an impediment.
Chapter 26
Context
At the church altar, just as the clergyman is about to ask Rochester whether he will take Jane as his wife, a stranger's voice interrupts the ceremony.
Analysis
The formal, legal diction—'declare the existence of an impediment'—borrows the exact language of the marriage liturgy that has just been read aloud, turning the church's own ritual formula into a weapon against the ceremony. This echo gives the interruption an air of institutional authority, as if the law and church themselves are speaking, not just one man. By choosing these words the speaker claims moral and legal legitimacy before he has even explained what the impediment is.
Essay Tip
Use this to argue that Brontë stages the novel's central crisis not as melodrama but as a conflict between competing claims of authority—Rochester's personal will versus the institutional power of law and religion, both encoded in ritual language.
