Theism

(the'izm.) [From Gr. Theos, God. ] The belief or acknowledgment of the existence of a God, as opposed to Atheism. It has sometimes been defined to be Deism; but T. differs from Deism, for although Deism implies a belief in the existence of a God, yet it signifies in modern usage a denial of revelation, which T. does not. [s. 891]
