Martin Chemnitz (Lutheran theologian) argues for the propriety of pictorial representation of God in light of Daniel 7 and the Father being depicted as an enthroned figure in the "Ancient of Days."

11 Finally, there are those who argue that other images can in a way be tolerated, but that no images of God and of Christ are to be made or tolerated. And indeed, if anyone should think that the essence of God can be expressed either with drawn lines or with various colors, or that the nature of the Godhead is such as the anthropomorphites imagine, he is deservedly condemned, as is written, Is. 40:18: “To whom will you liken God, or what likeness compare with Him?” If, however, not indeed the Godhead, but only those visible forms in which God in ancient time revealed His presence (as in Dan. 7:9 the Ancient of Days appears, and in Luke 3:22 the Holy Spirit descends in the bodily shape of a dove) are without any wrong opinion and without superstition painted historically, or if Christ is pictured in the form of a servant, in which God was manifested, as a reminder of the Gospel accounts, I do not dare simply to condemn this, even as it cannot be condemned when the figures of the divine visions in the Apocalypse are expressed in colors. Nevertheless, I gladly confess that it is dangerous to want to make any image of the Godhead, no matter under what pretext. For it is easy to run up against the law of God (Deut. 4:15 ff.; Is. 40:18 ff.; Acts 17:16-29). I confess that the best, surest, and most useful image of God and of Christ is the one which the understanding of our minds forms and conceives from the Word of God.
