Authoritative sacerdotal hierarchy controls for competitive holiness spirals which, unconstrained, are vicious positive feedback cycles that cannot but end in schism and war – in cultural disaster.
Holiness spirals are not first a search for social status, but rather for ontological safety. Nevertheless, once they have got going, they do result in an arms race to see who is holiest, thus of the highest moral and political rank, and thus least suitable as a scapegoat.
They are driven not by the nisus toward excellence, but by fear. Nor – apart from the minds of the spiritually ingenious – is the fear that drives them fundamentally supernatural – which is to say, in sane minds, sane and proper – but rather mundane, social, profane, and as such – not being ordered to the Truth himself, but to a Fallen social milieu – fundamentally disordered.
Holiness spirals are, first, a search for the proper constraints of true sanctity and righteousness upon conduct. When there is no established sacerdotal hierarchy that can authoritatively define the unquestionable constraints of holiness and righteousness, and then offer people a way to get back within those constraints when they have strayed beyond their pale – that can give them a way to know that they have reached safe harbor – people are going to push and push toward holiness however they can discern it according to their own best lights, without let or correction, and without possibility of any satisfactory completion of the search (because a forecondition of success for any search is a definition of success – such as can be authoritatively furnished to the searcher only by an incontrovertible authority). Anyone who disagrees with the notions of those who find that as a result of their quest for holiness they themselves are of the holiest sort then becomes a legitimate scapegoat in their eyes, and so a social enemy. There is then mutual repudiation and scapegoating of adversarial sectarians; mutual excommunication; schism; and, with the ensuing conflict of irreconcilable cults, civil war either hot or cold.
