Broad Church \Broad" Church`\ (Eccl.)
   A portion of the Church of England, consisting of persons who
   claim to hold a position, in respect to doctrine and
   fellowship, intermediate between the High Church party and
   the Low Church, or evangelical, party. The term has been
   applied to other bodies of men holding liberal or
   comprehensive views of Christian doctrine and fellowship.
   [1913 Webster]

         Side by side with these various shades of High and Low
         Church, another party of a different character has
         always existed in the Church of England. It is called
         by different names: Moderate, Catholic, or Broad
         Church, by its friends; Latitudinarian or Indifferent,
         by its enemies. Its distinctive character is the desire
         of comprehension. Its watch words are charity and
         toleration.                              --Conybeare.
