57. That all things of the Creed are true in so far as its verbal expressions are concerned, provided that instead of a Trinity of Persons there is understood a Trinity of Person, will be seen if we transcribe it again, with this latter trinity substituted in it. A Trinity of Person is this: THAT THE LORD'S DIVINE IS THE FATHER, THE DIVINE HUMAN THE SON, AND THE PROCEEDING DIVINE THE HOLY SPIRIT. When this trinity is understood, the man can both think of and say One God; but who fails to see that otherwise he cannot but think of three Gods? Athanasius himself saw this, and this is why there were inserted these words:
As we are compelled by the Christian verity to acknowledge every person by himself to be God and Lord; so are we forbidden by the Catholic religion (or, by the Christian faith) to say (or name) three gods or three lords. This amounts to saying, Although it is allowable, by the Christian verity, to acknowledge, or think of, three Gods and Lords, yet it is not allowable, by the Christian faith, to say or name more than one God and one Lord. And yet it is acknowledgment and thought which conjoin man with the Lord and heaven, and not mere speech. Besides, no one can comprehend how the Divine, which is one, can be divided into three Persons, each of whom is God, for the Divine is not divisible. And to make the three one through the essence or substance does not take away the idea of three Gods, but merely conveys an idea of their unanimity.
