When heretics are excommunicated from the fold of the holy catholic and apostolic Church, when are things right again? The answer of ‘when they hold the correct beliefs again’ is probably very common (if people believe in excommunication at all), but this is distinctly unchurchly: the Church isn’t optional, and the only way normally for healing to take place is through reconciliation and restoration to the Church. This idea also inevitably leaves people hanging with an unclear reattachment, whereas the break was manifest.
But this is probably why we think it’s enough to be right without being legitimately connected to the Body of the Church except by the futility of our own thoughts. Whose solipsistic idea was it that one’s thought, unconnected to the world, could connect people? Is this all that matters to salvation? For if it is, no wonder there’s the crypto-Pelagian idea floating around that intentions alone matter. But if so, then why would we excommunicate people for heresy in the first place?
Perhaps one may suggest that visible Church actions do make things happen and that we don’t have to be all hush-hush, mysterious and Gnostic about it.
