Theocracy
Theocracy or Ecclesiocracy, according to dictionary, is the "government of a state by immediate divine guidance or by officials who are regarded as divinely guided." The Oxford English Dictionary has this definition:
Synopsis
The word theocracy comes from the Greek words θεός (Theos), "God", and κρατία (kratia), "power, strength", and means "rule of God." A theocracy is a form in which the deity is considered immediate authority. In some religions, the king was regarded as the son of god and could not be even questioned; the attitude that the Quran declares should be taken towards the unique God:
Today, there is also a form of government where clerics have the power. From the perspective of the theocratic government, "God himself is recognized as the head" of the state, hence the term theocracy, from the Koine Greek θεοκρατία "rule of God", a term used by Josephus for the kingdoms of Israel and Judah.
Taken literally or strictly, theocracy means rule by God or gods and refers primarily to an internal "rule of the heart", especially in its biblical application. The common, generic use of the term, as defined above in terms of rule by a church or analogous religious leadership, would be more accurately described as an ecclesiocracy.
