Deist \De"ist\ (d[=e]"[i^]st), n. [L. deus god: cf. F.
   d['e]iste. See {Deity}.]
   One who believes in the existence of a God, but denies
   revealed religion; a freethinker.

   Note: A deist, as denying a revelation, is opposed to a
         Christian; as, opposed to the denier of a God, whether
         atheist or pantheist, a deist is generally denominated
         theist. --Latham.

   Syn: See {Infidel}.
