108. To spirits who were saying that they believed in three persons but only one God, because one essence or substance pertains to the three, I said "What need is there of the metaphysical term essence and substance?" So as to persuade them by this [I said] "Consult your thoughts. Consider whether you can think of three Gods, and so believe in three Gods and whether you can think metaphysically." It was found that it was so, for if there are three persons there are three Gods. That term admits no other result than that they are of one mind, or that one wills as the other, and what one does, the other wills, while yet their properties differ. Is not the Father petitioned for the sake of the Son and the Holy Spirit approached on account of enlightenment, the Father being adored for creation, the Son for redemption and the Holy Spirit for enlightenment Could this be admitted if God were three persons, and all of them the one or the other according to His works.
