XIX. But to my mind, he says, those things are said to be connumerated and of the same essence of which the names also correspond, as Three Men, or Three gods, but not Three this and that. What does this concession amount to? It is suitable to one laying down the law as to names, not to one who is asserting the truth. For I also will assert that Peter and James and John are not three or consubstantial, so long as I cannot say Three Peters, or Three Jameses, or Three Johns; for what you have reserved for common names we demand also for proper names, in accordance with your arrangement; or else you will be unfair in not conceding to others what you assume for yourself. What about John then, when in his Catholic Epistle he says that there are Three that bear witness, the Spirit and the Water and the Blood? Do you think he is talking nonsense? First, because he has ventured to reckon under one numeral things which are not consubstantial, though you say this ought to be done only in the case of things which are consubstantial. For who would assert that these are consubstantial? Secondly, because he has not been consistent in the way he has happened upon his terms; for after using Three in the masculine gender he adds three words which are neuter, contrary to the definitions and laws which you and your grammarians have laid down. For what is the difference between putting a masculine Three first, and then adding One and One and One in the neuter, or after a masculine One and One and One to use the Three not in the masculine but in the neuter, which you yourself disclaim in the case of Deity? What have you to say about the Crab, which may mean either an animal, or an instrument, or a constellation? And what about the Dog, now terrestrial, now aquatic, now celestial? Do you not see that three crabs or dogs are spoken of? Why of course it is so. Well then, are they therefore of one substance? None but a fool would say that. So you see how completely your argument from connumeration has broken down, and is refuted by all these instances. For if things that are of one substance are not always counted under one numeral, and things not of one substance are thus counted, and the pronunciation of the name once for all is used in both cases, what advantage do you gain towards your doctrine?
XX. I will look also at this further point, which is not without its bearing on the subject. One and One added together make Two; and Two resolved again becomes One and One, as is perfectly evident. If, however, elements which are added together must, as your theory requires, be consubstantial, and those which are separate be heterogeneous, then it will follow that the same things must be both consubstantial and heterogeneous. No: I laugh at your Counting Before and your Counting After, of which you are so proud, as if the facts themselves depended upon the order of their names. If this were so, according to the same law, since the same things are in consequence of the equality of their nature counted in Holy Scripture, sometimes in an earlier, sometimes in a later place, what prevents them from being at once more honourable and less honourable than themselves? I say the same of the names God and Lord, and of the prepositions Of Whom, and By Whom, and In Whom, by which you describe the Deity according to the rules of art for us, attributing the first to the Father, the second to the Son, and the third to the Holy Ghost. For what would you have done, if each of these expressions were constantly allotted to Each Person, when, the fact being that they are used of all the Persons, as is evident to those who have studied the question, you even so make them the ground of such inequality both of nature and dignity. This is sufficient for all who are not altogether wanting in sense. But since it is a matter of difficulty for you after you have once made an assault upon the Spirit, to check your rush, and not rather like a furious boar to push your quarrel to the bitter end, and to thrust yourself upon the knife until you have received the whole wound in your own breast; let us go on to see what further argument remains to you.
XXI. Over and over again you turn upon us the silence of Scripture. But that it is not a strange doctrine, nor an afterthought, but acknowledged and plainly set forth both by the ancients and many of our own day, is already demonstrated by many persons who have treated of this subject, and who have handled the Holy Scriptures, not with indifference or as a mere pastime, but have gone beneath the letter and looked into the inner meaning, and have been deemed worthy to see the hidden beauty, and have been irradiated by the light of knowledge. We, however in our turn will briefly prove it as far as may be, in order not to seem to be over-curious or improperly ambitious, building on another's foundation. But since the fact, that Scripture does not very clearly or very often write Him God in express words (as it does first the Father and afterwards the Son), becomes to you an occasion of blasphemy and of this excessive wordiness and impiety, we will release you from this inconvenience by a short discussion of things and names, and especially of their use in Holy Scripture.
XXII. Some things have no existence, but are spoken of; others which do exist are not spoken of; some neither exist nor are spoken of, and some both exist and are spoken of. Do you ask me for proof of this? I am ready to give it. According to Scripture God sleeps and is awake, is angry, walks, has the Cherubim for His Throne. And yet when did He become liable to passion, and have you ever heard that God has a body? This then is, though not really fact, a figure of speech. For we have given names according to our own comprehension from our own attributes to those of God. His remaining silent apart from us, and as it were not caring for us, for reasons known to Himself, is what we call His sleeping; for our own sleep is such a state of inactivity. And again, His sudden turning to do us good is the waking up; for waking is the dissolution of sleep, as visitation is of turning away. And when He punishes, we say He is angry; for so it is with us, punishment is the result of anger. And His working, now here now there, we call walking; for walking is change from one place to another. His resting among the Holy Hosts, and as it were loving to dwell among them, is His sitting and being enthroned; this, too, from ourselves, for God rests nowhere as He does upon the Saints. His swiftness of moving is called flying, and His watchful care is called His Face, and his giving and bestowing is His hand; and, in a word, every other of the powers or activities of God has depicted for us some other corporeal one.
