You've probably heard of a lot of other "isms" when it comes to beliefs. There's agnosticism (not sure if there is a God), #theism (belief in one or more Gods), monotheism (one God), polytheism (many gods), deism (belief that there is a God, but he's not personally involved), and even atheism (belief in no God). Get ready to add a new ism to your vocabulary: #omnism.
