108. To spirits who were saying that they believed in three Persons and still one God, because there is one essence or substance to the three, I said "What need is there of the metaphysical term essence, and substance?" that I might by this means persuade them. "Consult your thoughts; do you not think of three Gods? And so do you not believe in three Gods? Can you by any means think metaphysically?" And it was found that it was so; for if there are three Persons there are three Gods. That term involves nothing else than that they are of one mind; or that what one wills another wills; and what one does another wills; and then their properties differ; and then the Father is implored for the sake of the Son, and the Holy Spirit is approached for the sake of enlightenment; the Father is adored on account of creation, the Son on account of redemption, and the Holy Spirit for the sake of enlightenment. Would not this be allowable if God were three Persons? And each is one and another, as to works.
