The belief that there is only one God, who is the Creator of the universe. It is first of all theism, because it recognizes the existence of a personal God, with mind and will, who is really distinct from the world he created. It is therefore not monism, which identifies God and the universe. Moreover it affirms that this personal and transcendent God is uniquely one and not plural, hence it is opposed to polytheism and dualism. (Etym. Greek monos, single + theos, god.)
