Of the Superintendence of Doctrine.
The sovereign is not the judge of the truth of doctrine; he may judge for himself, like all other men; but he ought to take cognizance of it in respect to everything which relates to civil order, whether in regard to purport or delivery.
This is the general rule from which magistrates ought never to depart. Nothing in a doctrine merits the attention of the police, except as it interests public order: it is the influence of doctrine upon manners that decides its importance. Doctrines which have a distant connection only with good conduct can never be fundamental. Truths which conduce to render mankind gentle, humane, obedient to the laws and to the government, interest the State, and proceed evidently from God.
