Of Idols or Images of God, Christ and The Saints
Images of God. Since God as Spirit is in essence invisible and immense, he cannot really be expressed by any art or image. For this reason we have no fear pronouncing with Scripture that images of God are mere lies. Therefore we reject not only the idols of the Gentiles, but also the images of Christians. Although Christ assumed human nature, yet he did not on that account assume it in order to provide a model for carvers and painters. He denied that he had come to abolish the law and the prophets (Matt. 5:17). But images are forbidden by the law and the prophets (Deut. 4:15; Isa. 44:9). He denied that his bodily presence would be profitable for the Church, and promised that he would be near us by his Spirit forever (John 16:7). Who, therefore, would believe that a shadow or likeness of his body would contribute any benefit to the pious? (II Cor. 5:5). Since he abides in us by his Spirit, we are therefore the temple of God (II Cor. 3:16). But what agreement has the temple of God with idols? (II Cor. 6:16).

"QUESTION 5: Is it not lawful to have images or pictures of God by us, so we do not worship them, nor God by them?
ANSWER: The images or pictures of God are an abomination, and utterly unlawful, because they debase God, and may be a cause of idolatrous worship.
QUESTION 6: Is it not lawful to have pictures of Jesus Christ, he being a man as well as God?
ANSWER: It is not lawful to have pictures of Jesus Christ, because his divine nature cannot be pictured at all; and because his body, as it is now glorified, cannot be pictured as it is; and because, if it do not stir up devotion, it is in vain; if it stir up devotion, it is a worshipping by an image or picture, and so a palpable breach of the second commandment." [Thomas Vincent, A Family Instructional Guide]
(1679) John Owen, The Glory of Christ
Many there are who, not comprehending, not being affected with, that divine, spiritual description of the person of Christ which is given us by the Holy Ghost in the Scripture, do feign unto themselves false representations of him by images and pictures, so as to excite carnal and corrupt affections in their minds. By the help of their outward senses, they reflect on their imaginations the shape of a human body, cast into postures and circumstances dolorous or triumphant; and so, by the working of their fancy, raise a commotion of mind in themselves, which they suppose to be love unto Christ. But all these idols are teaches of lies. The true beauty and amiableness of the person of Christ, which is the formal object and cause of divine love, is so far from being represented herein, as that the mind is thereby wholly diverted from the contemplation of it. For no more can be so pictured unto us but what may belong unto a mere man, and what is arbitrarily referred unto Christ, not by faith, but by corrupt imagination.
The beauty of the person of Christ, as represented in the Scripture, consists in things invisible unto the eyes of flesh. They are such as no hand of man can represent or shadow. It is the eye of faith alone that can see this King in his beauty. What else can contemplate on the untreated glories of his divine nature? Can the hand of man represent the union of his natures in the same person, wherein he is peculiarly amiable? What eye can discern the mutual communications of the properties of his different natures in the same person, which depends thereon, whence it is that God laid down his life for us, and purchased his church with his own blood? In these things, O vain man! does the loveliness of the person of Christ unto the souls of believers consist, and not in those strokes of art which fancy has guided a skilful hand and pencil unto. And what eye of flesh can discern the inhabitation of the Spirit in all fulness in the human nature? Can his condescension, his love, his grace, his power, his compassion, his offices, his fitness and ability to save sinners, be deciphered on a tablet, or engraven on wood or stone? However such pictures may be adorned, however beautified and enriched, they are not that Christ which the soul of the spouse does love;they are not any means of representing his love unto us, or of conveying our love unto him;they only divert the minds of superstitious persons from the Son of God, unto the embraces of a cloud, composed of fancy and imagination.
Others there are who abhor these idols, and when they have so done, commit sacrilege. As they reject images, so they seem to do all love unto the person of Christ, distinct from other acts of obedience, as a fond imagination. But the most superstitious love unto Christthat is, love acted in ways tainted with superstitionis better than none at all. But with what eyes do such persons read the Scriptures? With what hearts do they consider them? What do they conceive is the intention of the Holy Ghost in all those descriptions which he gives us of the person of Christ as amiable and desirable above all things, making wherewithal a proposal of him unto our affectionsinciting us to receive him by faith, and to cleave unto him in love? yea, to what end is our nature endued with this affectionunto what end is the power of it renewed in us by the sanctification of the Holy Spiritif it may not be fixed on this most proper and excellent object of it? This is the foundation of our love unto Christ namely, the revelation and proposal of him unto us in the Scripture as altogether lovely. The discovery that is made therein of the glorious excellencies and endowments of his personof his love, his goodness, and graceof his worth and workis that which engageth the affections of believers unto him. It may be said, that if there be such a proposal of him made unto all promiscuously, then all would equally discern his amiableness and be affected with it, who assent equally unto the truth of that revelation. But it has always fallen out otherwise. In the days of his flesh, some that looked on him could see neither “ form nor comeliness ” in him Therefore he should be desired; others saw his glory“ glory as of the only-begotten of the Father, full of grace and truth ”. To some he is precious; unto others he is disallowed and rejecteda stone which the builders refused, when others brought it forth, crying, “ Grace, grace unto it ” as the head of the corner. Some can see nothing but weakness in him; unto others the wisdom and power of God do evidently shine forth in him. Therefore it must be said, that notwithstanding that open, plain representation that is made of him in the Scripture, unless the holy Spirit gives us eyes to discern it, and circumcise our hearts by the cutting off corrupt prejudices and all effects of unbelief, implanting in them, by the efficacy of his grace, this blessed affection of love unto him, all these things will make no impression on our minds.
As it was with the people on the giving of the law, notwithstanding all the great and mighty works which God had wrought among them, yet having not given them “ a heart to perceive, and eyes to see, and ears to hear ”which he affirms that he had not done, Deut. 29: 4 ,they were not moved unto faith or obedience by them; so is it in the preaching of the gospel. Notwithstanding all the blessed revelation that is made of the excellencies of the person of Christ therein, yet those into whose hearts God does not shine to give the knowledge of his glory in his face, can discern nothing of it, nor are their hearts affected with it.
We do not, therefore, in these things, follow “ cunningly-devised fables. ” We do not indulge unto our own fancies and imaginations; they are not unaccountable raptures or ecstasies which are pretended unto, nor such an artificial conjoining of thoughts as some ignorant of these things do boast that they can give an account of.
Our love to Christ ariseth alone from the revelation that is made of him in the Scripture is ingenerated, regulated, measured, and is to be judged thereby.

Q. 9. May we not have a picture of Christ, who has a true body?
A. By no means; because, though he has a true body and a reasonable soul, John 1:14, yet his human nature subsists in his divine person, which no picture can represent, Psalm 45:2.
Q. 10. Why ought all pictures of Christ to be abominated by Christians?
A. Because they are downright lies, representing no more than the picture of a mere man: whereas, the true Christ is God-man; "Immanuel, God with us," 1 Tim. 3:16; Matt. 1:23.

2. Is it wrong to make paintings or pictures of our Savior Jesus Christ? According to the Larger Catechism, this is certainly wrong, for the catechism interprets the second commandment as forbidding the making of any representation of any of the three persons of the Trinity, which would certainly include Jesus Christ, the second person of the Trinity, God the Son. While pictures of Jesus are extremely common in the present day, we should realize that in Calvinistic circles this is a relatively modern development. Our forefathers at the time of the Reformation, and for perhaps 300 years afterward, scrupulously refrained, as a matter of principle, from sanctioning or making use of pictures of Jesus Christ. Such pictures are so common in the present day, and so few people have conscientious objections to them, that; it is practically impossible to obtain any Sabbath School helps or Bible story; material for children that is free of such pictures. The American Bible Society is to be commended for its decision that the figure of the Savior may not appear in Bible motion pictures issued by the Society.
3. What attitude should we adopt in view of the present popularity of pictures of Jesus Christ? The following considerations may be suggested as bearing on this question: (a) The Bible presents no information whatever about the personal appearance of Jesus Christ, but it does teach that we are not to think of him as he may have appeared "in the days of his flesh," but as he is today in heavenly glory, in his estate of exaltation (2 Cor. 5:46). (b) Inasmuch as the Bible presents no data about the personal appearance of our Savior, all artists' pictures of him are wholly imaginary and constitute only the artists' ideas of his character and appearance. (c) Unquestionably pictures of the Savior have been very greatly influenced by the theological viewpoint of the artist. The typical modem picture of Jesus is the product of nineteenth-century "Liberalism" and presents a "gentle Jesus" who emphasized only the love and Fatherhood of God and said little or nothing about sin, judgment, and eternal punishment. (d) Perhaps more people living today have derived their ideas of Jesus Christ from these typically "liberal" pictures of Jesus than have derived their ideas of Jesus from the Bible itself. Such people inevitably think of Jesus as a human person, rather than thinking of him according to the biblical teaching as a divine person with a human nature. The inevitable effect of the popular acceptance of pictures of Jesus is to overemphasize his humanity and to forget or neglect his deity (which of course no picture can portray). (e) In dealing with an evil so widespread and almost universally accepted, we should bear a clear testimony against what we believe to be wrong, but we should not expect any sudden change in Christian sentiment on this question. It will require many years of education in scriptural principles before the churches and their members can be brought back to the high position of the Westminster Assembly on this question. Patience will be required.
4. Are not pictures of Jesus legitimate provided they are not worshiped or used as "aids to worship"? As interpreted by the Westminster Assembly, the second commandment certainly forbids all representations of any of the persons of the Trinity, and this coupled with the truth taught in the Westminster Standards that Christ is a divine person with a human nature taken into union with himself, and not a human person, would imply that it is wrong to make pictures of Jesus Christ for any purpose whatever. Of course, there is a difference between using pictures of Jesus to illustrate children's Bible story books or lessons, and using pictures of Jesus in worship as Roman Catholics use them. Admittedly the former is not an evil in the same class with the latter. In spite of this distinction, however, there are good reasons for holding that our forefathers of the Reformation were right in opposing all pictorial representation of the Savior. We should realize that the popularity - even the almost unchallenged prevalence - of a particular practice does not prove that it is right. To prove that a practice is right we must show that it is in harmony with the commands and principles revealed in the Word of God. Merely showing that a practice is common, is useful, or seems to have good results does not prove it is right.
(1961) Pictures of Christ by Prof. John Murray
"Secondly, pictures of Christ are in principle a violation of the second commandment. A picture of Christ, if it serves any useful purpose, must evoke some thought or feeling respecting him and, in view of what he is, this thought or feeling will be worshipful. We cannot avoid making the picture a medium of worship. But since the materials for this medium of worship are not derived from the only revelation we possess respecting Jesus, namely, Scripture, the worship is constrained by a creation of the human mind that has no revelatory warrant. This is will-worship. For the principle of the second commandment is that we are to worship God only in ways prescribed and authorized by him. It is a grievous sin to have worship constrained by a human figment, and that is what a picture of the Saviour involves."
(1970) The Shorter Catechism For Study Classes by G.I. Williamson
The second commandment is broken when men attempt to make a graven image or a picture of the Lord Jesus Christ. The Bible teaches us that there is one God. It teaches us to worship the three persons, the father, the Son, and the Holy Spirit, as one God, the same in substance, equal in power and glory. But Paul tells us that we "ought not to think that the Godhead is like unto gold, or silver, or stone graven by art and man's device" (Acts 17:29)...
There was a time when the Protestants recognized this evil. They saw the images in the Roman Catholic Church and they understood that this was a violation of the second commandment. They realized that this was wrong - this making of images and likenesses of Christ - even though the Roman Catholic Church was careful to say that it did not want people to worship these images, but only to worship the Lord through these images. But now, it seems, many Protestants have accepted the Roman Catholic position. They may not realize this. And they may still think, in their minds, that there is an important difference between a statue (image) and a picture (likeness). But the commandment recognizes no such difference. It forbids us to make any likeness, just as it forbids us to make any image, of the Lord.
