(From the Greek pan, all + theos, God)
The idea that God is everything and everything is God.
1. The OED defines the term as: "The religious belief or philosophical theory that God and the universe are identical (implying a denial of the personality and transcendence of God)" - OED
2. "Pantheism holds that God and the world are not distinct, and everything in the world is part of God."
(Bertrand Russell, History of Philosophy, 353)
