   note: the term orthodox differs in its use among the various
         christian communions. the greek church styles itself
         the "holy orthodox apostolic church," regarding all
         other bodies of christians as more or less heterodox.
         the roman catholic church regards the protestant
         churches as heterodox in many points. in the united
         states the term orthodox is frequently used with
         reference to divergent views on the doctrine of the
         trinity. thus it has been common to speak of the
         trinitarian congregational churches in distinction from
         the unitarian, as orthodox.` the name is also applied
         to the conservative, in distinction from the "liberal",
         or hicksite, body in the society of friends.
