Athanasian \Ath`a*na"sian\ (?; 277), a.
   Of or pertaining to Athanasius, bishop of Alexandria in the
   4th century.

   {Athanasian creed}, a formulary, confession, or exposition of
      faith, formerly supposed to have been drawn up by
      Athanasius; but this opinion is now rejected, and the
      composition is ascribed by some to Hilary, bishop of Arles
      (5th century). It is a summary of what was called the
      orthodox faith.

      the articles of Christian faith; a confession of faith for
      public use; esp., one which is brief and comprehensive.

            co["o]rdinate with, but always subordinate to, the
            Bible.                                --Schaff-Herzog
