The decrees made by the 338 bishops attending this council were quickly overturned by the second Council of Nicaea. However, they spoke some great truth that we should consider today. The sinful worship of Mary and the saints was accepted by this council, so we must be sure to discern their words carefully. The Council also condemns other art, which I disagree with. I do however agree with their position on images of Christ.
“The only admissible figure of the humanity of Christ, however, is bread and wine in the holy Supper.”
Moreover, we can prove our view by Holy Scripture and the Fathers. In the former it is said: “God is a Spirit: and they that worship him must worship him in spirit and in truth;” and: “Thou shalt not make thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath;” on which account God spoke to the Israelites on the Mount, from the midst of the fire, but showed them no image. Further: “They changed the glory of the incorruptible God into an image made like to corruptible man,…and served the creature more than the Creator.”
The Council explains their position well:
Wherefore we thought it right, to shew forth with all accuracy, in our present definition the error of such as make and venerate these, for it is the unanimous doctrine of all the holy Fathers and of the six Ecumenical Synods, that no one may imagine any kind of separation or mingling in opposition to the unsearchable, unspeakable, and incomprehensible union of the two natures in the one hypostasis or person. What avails, then, the folly of the painter, who from sinful love of gain depicts that which should not be depicted–that is, with his polluted hands he tries to fashion that which should only be believed in the heart and confessed with the mouth? He makes an image and calls it Christ. The name Christ signifies God and man. Consequently it is an image of God and man, and consequently he has in his foolish mind, in his representation of the created flesh, depicted the Godhead which cannot be represented, and thus mingled what should not be mingled. Thus he is guilty of a double blasphemy–the one in making an image of the Godhead, and the other by mingling the Godhead and manhood. Those fall into the same blasphemy who venerate the image, and the same woe rests upon both, because they err with Arius, Dioscorus, and Eutyches, and with the heresy of the Acephali. When, however, they are blamed for undertaking to depict the divine nature of Christ, which should not be depicted, they take refuge in the excuse: We represent only the flesh of Christ which we have seen and handled. But that is a Nestorian error. For it should be considered that that flesh was also the flesh of God the Word, without any separation, perfectly assumed by the divine nature and made wholly divine. How could it now be separated and represented apart? So is it with the human soul of Christ which mediates between the Godhead of the Son and the dulness of the flesh. As the human flesh is at the same time flesh of God the Word, so is the human soul also soul of God the Word, and both at the same time, the soul being deified as well as the body, and the Godhead remained undivided even in the separation of the soul from the body in his voluntary passion. For where the soul of Christ is, there is also his Godhead; and where the body of Christ is, there too is his Godhead. If then in his passion the divinity remained inseparable from these, how do the fools venture to separate the flesh from the Godhead, and represent it by itself as the image of a mere man? They fall into the abyss of impiety, since they separate the flesh from the Godhead, ascribe to it a subsistence of its own, a personality of its own, which they depict, and thus introduce a fourth person into the Trinity. Moreover, they represent as not being made divine, that which has been made divine by being assumed by the Godhead. Whoever, then, makes an image of Christ, either depicts the Godhead which cannot be depicted, and mingles it with the manhood (like the Monophysites), or he represents the body of Christ as not made divine and separate and as a person apart, like the Nestorians. [emphasis added]
The Council continues by anathematizing those who continue in sinful idol creation or worship:
(8) If anyone ventures to represent the divine image (χαρακτήρ) of the Word after the Incarnation with material colours, let him be anathema!
(9) If anyone ventures to represent in human figures, by means of material colours, by reason of the incarnation, the substance or person (ousia or hypostasis) of the Word, which cannot be depicted, and does not rather confess that even after the Incarnation he [i.e., the Word] cannot be depicted, let him be anathema!
(10) If anyone ventures to represent the hypostatic union of the two natures in a picture, and calls it Christ, and thus falsely represents a union of the two natures, etc.!
(11) If anyone separates the flesh united with the person of the Word from it, and endeavours to represent it separately in a picture, etc.!
(12) If anyone separates the one Christ into two persons, and endeavours to represent Him who was born of the Virgin separately, and thus accepts only a relative (σχετική) union of the natures, etc.
(13) If anyone represents in a picture the flesh deified by its union with the Word, and thus separates it from the Godhead, etc.
(14) If anyone endeavours to represent by material colours, God the Word as a mere man, who, although bearing the form of God, yet has assumed the form of a servant in his own person, and thus endeavours to separate him from his inseparable Godhead, so that he thereby introduces a quaternity into the Holy Trinity, etc.
