Nestorian \Nes*to"ri*an\, prop. n. (Eccl. Hist.)
   An adherent of Nestorius, patriarch of Constantinople in the

   one nature in Christ (who was God in man), and, hence, that
   it was improper to call Mary the mother of God though she
   might be called the mother of Christ; also, one of the sect
   established by the followers of Nestorius in Persia, India,
   and other Oriental countries, and still in existence. Opposed
