explain the nature of God, but accommodate the knowledge of him to our narrow capacity; to accomplish which, the Scripture must necessarily descend far below the height of his majesty.
II. But he also designates himself by another peculiar character, by which he may be yet more clearly distinguished; for, while he declares himself to be but One, he proposes himself to be distinctly considered in Three Persons, without apprehending which, we have only a bare and empty name of God floating in our brains, without any idea of the true God. Now, that no one may vainly dream of three gods, or suppose that the simple essence of God is divided among the three Persons, we must seek for a short and easy definition, which will preserve us from all error. But since some violently object to the word Person, as of human invention, we must first examine the reasonableness of this objection. When the Apostle denominates the Son the express image of the hypostasis of the Father, he undoubtedly ascribes to the Father some subsistence, in which he differs from the Son. For to understand this word as synonymous with Essence, (as some interpreters have done, as though Christ, like wax impressed with a seal, represented in himself the substance of the Father,) were not only harsh, but also absurd. For the essence of God being simple and indivisible, he who contains all in himself, not in part, or by derivation, but in complete perfection, could not, without impropriety, and even absurdity, be called the express image of it. But since the Father, although distinguished by his own peculiar property, hath expressed himself entirely in his Son, it is with the greatest reason asserted that he hath made his hypostasis conspicuous in him; with which the other appellation, given him in the same passage, of “the brightness of his glory,” exactly corresponds. From the words of the Apostle, we certainly conclude, that there is in the Father a proper hypostasis, which is conspicuous in the Son. And thence also we easily infer the hypostasis of the Son, which distinguishes him from the Father. The same reasoning is applicable to the Holy Spirit; for we shall soon prove him also to be God; and yet he must, of necessity, be considered as distinct from the Father. But this is not a distinction of the essence, which it is unlawful to represent as any other than simple and undivided. It follows, therefore, if the testimony of the Apostle be credited, that there are in God three hypostases. And, as the Latins have expressed the same thing by the word person, it is too fastidious and obstinate to contend about so clear a matter. If we wish to translate word for word, we may call it subsistence. Many, in the same sense, have called it substance. Nor has the word person been used by the Latins only; but the Greeks also, for the sake of testifying their consent to this doctrine, taught the existence of three προσωπα (persons) in God. But both Greeks and Latins, notwithstanding any verbal difference, are in perfect harmony respecting the doctrine itself.
