On the Incarnation of Christ
6 To explain the matter more fully, it will not appear absurd to make use of an illustration, although on a subject of so much difficulty it is not easy to obtain suitable illustrations. However, if we may speak without offense, the metal iron is capable of cold and heat. If, then, a mass of iron be kept constantly in the fire, receiving the heat through all its pores and veins, and the fire being continuous and the iron never removed from it, it become wholly converted into the latter; could we at all say of this, which is by nature a mass of iron, that when placed in the fire, and incessantly burning, it was at any time capable of admitting cold? On the contrary, because it is more consistent with truth, do we not rather say, what we often see happening in furnaces, that it has become wholly fire, seeing nothing but fire is visible in it? And if any one were to attempt to touch or handle it, he would experience the action not of iron, but of fire. In this way, then, that soul which, like an iron in the fire, has been perpetually placed in the Word, and perpetually in the Wisdom, and perpetually in God, is God in all that it does, feels, and understands, and therefore can be called neither convertible nor mutable, inasmuch as, being incessantly heated, it possessed immutability from its union with the Word of God. To all the saints, finally, some warmth from the Word of God must be supposed to have passed; and in this soul the divine fire itself must be believed to have rested, from which some warmth may have passed to others. Lastly, the expression, “God, your God, anointed you with the oil of gladness above your fellows,” shows that that soul is anointed in one way with the oil of gladness, i.e., with the word of God and wisdom; and his fellows, i.e., the holy prophets and apostles, in another. For they are said to have “run in the odour of his ointments;” and that soul was the vessel which contained that very ointment of whose fragrance all the worthy prophets and apostles were made partakers. As, then, the substance of an ointment is one thing and its odour another, so also Christ is one thing and His fellows another. And as the vessel itself, which contains the substance of the ointment, can by no means admit any foul smell; whereas it is possible that those who enjoy its odour may, if they remove a little way from its fragrance, receive any foul odour which comes upon them: so, in the same way, was it impossible that Christ, being as it were the vessel itself, in which was the substance of the ointment, should receive an odour of an opposite kind, while they who are His “fellows” will be partakers and receivers of His odour, in proportion to their nearness to the vessel.
7. I think, indeed, that Jeremiah the prophet, also, understanding what was the nature of the wisdom of God in him, which was the same also which he had assumed for the salvation of the world, said, “The breath of our countenance is Christ the Lord, to whom we said, that under His shadow we shall live among the nations.” And inasmuch as the shadow of our body is inseparable from the body, and unavoidably performs and repeats its movements and gestures, I think that he, wishing to point out the work of Christ's soul, and the movements inseparably belonging to it, and which accomplished everything according to His movements and will, called this the shadow of Christ the Lord, under which shadow we were to live among the nations. For in the mystery of this assumption the nations live, who, imitating it through faith, come to salvation. David also, when saying, “Be mindful of my reproach, O Lord, with which they reproached me in exchange for Your Christ,” seems to me to indicate the same. And what else does Paul mean when he says, “Your life is hid with Christ in God;” and again in another passage, “Do you seek a proof of Christ, who speaks in me?” And now he says that Christ was hid in God. The meaning of which expression, unless it be shown to be something such as we have pointed out above as intended by the prophet in the words “shadow of Christ,” exceeds, perhaps, the apprehension of the human mind. But we see also very many other statements in holy Scripture respecting the meaning of the word “shadow,” as that well-known one in the Gospel according to Luke, where Gabriel says to Mary, “The Spirit of the Lord shall come upon you, and the power of the Highest shall overshadow you.” And the apostle says with reference to the law, that they who have circumcision in the flesh, “serve for the similitude and shadow of heavenly things.” And elsewhere, “Is not our life upon the earth a shadow?” If, then, not only the law which is upon the earth is a shadow, but also all our life which is upon the earth is the same, and we live among the nations under the shadow of Christ, we must see whether the truth of all these shadows may not come to be known in that revelation, when no longer through a glass, and darkly, but face to face, all the saints shall deserve to behold the glory of God, and the causes and truth of things. And the pledge of this truth being already received through the Holy Spirit, the apostle said, “Yea, though we have known Christ after the flesh, yet now henceforth know we Him no more.”
The above, meanwhile, are the thoughts which have occurred to us, when treating of subjects of such difficulty as the incarnation and deity of Christ. If there be any one, indeed, who can discover something better, and who can establish his assertions by clearer proofs from holy Scriptures, let his opinion be received in preference to mine.
