“False doctrine and heresy are even worse than schism. If people separate themselves from teaching which is positively false and unscriptural, they ought to be praised rather than reproved. In such cases separation is a virtue and not a sin… there is one thing which is even worse than controversy, and that is false doctrine, allowed, and permitted without protest or molestation.”
–Bishop J.C. Ryle
