Polity.
Synonyms:
constitution, policy, form or system of government.
Polity is the permanent system of government of a state, a church, or a society; policy is the method of management with reference to the attainment of certain ends; the national polity of the United States is republican; each administration has a policy of its own. Policy is often used as equivalent to expediency; as, many think honesty to be good policy. Polity used in ecclesiastical use serves a valuable purpose in distinguishing that which relates to administration and government from that which relates to faith and doctrine; two churches identical in faith may differ in polity, or those agreeing in polity may differ in faith.
