I have seen, and so have many more, two waters, one of the river, the other a mineral water, so like that no man could discern the one from the other by his sight; yet when they have been both put together, the whole substance could not by the eye be distinguished from milk. Yet we know that the one was not mixed with the other, so as every part of the one to be in every part of the other, for that is impossible, unless two bodies can be in the same place. How then could the change be made in every part, but only by the activity of the mineral water, changing it every where to the sense, and yet not being every where, and in every part of the water? If then such gross bodies have so great activity, what shall we think of spirits, whose kinds be as many as there be kinds of liquor, and activity greater? Can it then be doubted, but that God, who is an infinitely fine Spirit, and withal intelligent, can make and change all species and kinds of body as he pleaseth? But I dare not say, that this is the way by which God Almighty worketh, because it is past my apprehension: yet it serves very well to demonstrate, that the omnipotence of God implieth no contradiction; and is better than by pretence of magnifying the fineness of the Divine substance, to reduce it to a spright or phantasm, which is nothing. A _person_ (Latin, _persona_) signifies an intelligent substance, that acteth any thing in his own or another’s name, or by his own or another’s authority. Of this definition there can be no other proof than from the use of that word, in such Latin authors as were esteemed the most skilful in their own language, of which number was Cicero. But Cicero, in an epistle to Atticus, saith thus: _Unus sustineo tres personas, mei, adversarii, et judicis_: that is, “I that am but one man, sustain three persons; mine own person, the person of my adversary, and the person of the judge.” Cicero was here the substance intelligent, one man; and because he pleaded for himself, he calls himself his own person: and again, because he pleaded for his adversary, he says, he sustained the person of his adversary: and lastly, because he himself gave the sentence, he says, he sustained the person of the judge. In the same sense we use the word in English vulgarly, calling him that acteth by his own authority, his own person, and him that acteth by the authority of another, the person of that other. And thus we have the exact meaning of the word _person_. The Greek tongue cannot render it; for πρὸσωπον is properly a face, and, metaphorically, a vizard of an actor upon the stage. How then did the Greek Fathers render the word _person_, as it is in the blessed Trinity? Not well. Instead of the word _person_ they put _hypostasis_, which signifies substance; from whence it might be inferred, that the three persons in the Trinity are three Divine substances, that is, three Gods. The word πρὸσωπον they could not use, because face and vizard are neither of them
