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. Schaff-Herzog Encyc.
