The recognition that divine life is expressing itself as all that there is, including humans, and thus rendering meaningless the concept of any "God" that is separate from, holding power over, or judging the human experience; embodying one's individual divinity so completely that one becomes a delivery system of infinite life energy, creativity and divine love intelligence.
As we learn more about the true nature of the universe, and explore and apply science, we evolve from superstitious beliefs in polytheism and monotheism and embrace omnitheism.
A religion that includes all possible deities (i.e. the flying spaghetti monster,thor, zeus, yahweh, ganesha) and the events that are influenced by them. It explains the universe's beginning as a quarrel between all of the gods because of ganesha's superior size. The great spirit mistakingly decreases his volume and creates a black hole. This focuses all of the particles that made up the deities into one point which causes the big bang.
P.S. Omnitheism is a religion created to display the fault in shunning all possible other gods. Mneurgh.
