 One may wonder if there could be two omnipotent beings; there have been arguments from theism (at least one god) to monotheism (exactly one god) based on the idea that it’d be impossible for there to be more than one who is omnipotent. (See the Monotheism entry, section  5.)  Suppose that one omnipotent being willed a certain object to move and simultaneously another omnipotent being willed that it should remain in place. It would seem that whether the object moves or stays in place, one of the being’s wills is thwarted, so that, contrary to our stipulation, one of them fails to be omnipotent. Swinburne argues that such conflicts of will are impossible given the omniscience, perfect goodness, and causal relations of the omnipotent beings. In his view, in causing the Son and Spirit, the Father must “lay down the rules determining who has the right to do which actions; and the other members of the Trinity would recognize his right, as the source of their being to lay them down” (428).
