PRIESTDOM — [Noun] Political rule or sweeping social control exercised by a class of priests, or priests collectively. From priest (from Old English prēost, ultimately from Greek presbyteros, "elder") + -dom (a suffix forming nouns denoting a state, condition, or domain, from Old English -dōm). Unlike "priesthood," which denotes office or collective body, or "priestcraft," which suggests the cunning arts of influence, priestdom is the sobering, institutional fact of sacred power made manifest in law, land, and ledger. It is the shadow of a spire falling across a tax ledger, the state edict recited as liturgy, and the profound quiet of a populace that has learned to police its own thoughts—the final triumph of the sacred over the merely human.
