It used to be that the State had an established Religion that worked with the state to establish Truth and its boundaries. Therefore the Spanish Inquisition was not merely a religious event but a State event, where heretics were considered seditious or treasonous, and thus handed over to the State to be dealt with before it could be destabilized by dangerous thoughts, words, and actions.

Now what do we do about Truth in this age of disestablishmentarianism? There is no one Religion of the State, and therefore there is no one Truth, there is a Plurality of Truths. That seems to present an existential problem for arbiters of Truth within the borders of the State, doesn't it.
