Theology of icons
The foes of images explicitly deny that the New Testament, in relation to the Old Testament, contains any new attitude toward images. Their basic theological outlook is that the divine is beyond all earthly form in its transcendence and spirituality; representation in earthly substances and forms of the divine already indicate its profanation. The relationship to God, who is Spirit, can only be a purely spiritual one; the worship of the individual as well as the community can happen only “in spirit and in truth” (John 4:24). Similarly, the divine archetype can also be realized only spiritually and morally in life. The religious path of the action of God upon humans is not the path of external influence upon the senses but rather that of spiritual action upon the mind and the will. Such an effect does not come about through the art of painting. Opponents of icons thus claim that the only way to reach an understanding of the truth is by studying the writings of the Old and New Testaments, which are filled with the Spirit of God.
The decisive contrast between the iconodules (image lovers) and the iconoclasts (image destroyers) is found in their understanding of Christology. The iconodules based their theology upon the view of Athanasius—who reflected Alexandrian Christology—that Christ, the God become human, is the visible, earthly, and corporeal icon of the heavenly Father, created by God himself. The iconoclasts, on the other hand, explain, in terms of ancient Antiochene Christology, that the image conflicts with the ecclesiastical dogma of the Person of the Redeemer. It is unseemly, according to their views, to desire to portray a personality such as Christ, who is himself divine, because that would mean pulling the divine down into the materialistic realm.
The history of iconoclasm began in the early church with an emphatic (and, from the viewpoint of lovers of Greek and Roman culture, catastrophic) iconoclastic movement that led to the annihilation of nearly all of the sacred art of the pagan religions of the Roman Empire. In Western Christendom, an iconoclastic attitude was again expressed in various medieval lay movements and sects. Iconoclasm underwent a revolutionary outbreak in the 16th-century Reformation in Germany, France, and England. Despite the different historical types of iconoclasm, a surprising uniformity in regard to their affective structure and theological argumentation exists. The Iconoclastic Controversy of the 8th and 9th centuries also became a point of contention in the Western Church. To be sure, the latter had recognized the seventh ecumenical council at Nicaea (787), in which iconoclasm was condemned. Nevertheless, an entirely different situation existed in the West. The Frankish–Germanic Church was a young church in which images were much more infrequent than in the old Byzantine Church, in which holy icons had accumulated over the centuries. In the West there was still no Christian pictorial art as highly developed as in the East. Also, Christianity there did not have to struggle against a highly developed pagan pictorial art. Donar, a Germanic god, reputedly whispered in a holy oak, and Boniface merely had to fell the Donar oak in order to demonstrate the superiority of Christ over the pagan god. Among the Germanic tribes in the West, there was no guild of sculptors or goldsmiths, as in Ephesus (Acts 19:24 ff.), who would have been able to protest in the name of their gods against the Christian iconoclasts.
The Western viewpoint is revealed most clearly in the formulations of the synodal decisions on the question of images, as they were promulgated in the Frankish kingdom in the Libri Carolini, a theological treatise composed primarily by Theodulf of Orléans at Charlemagne’s request. In this work it is emphasized that images have only a representative character. Thus, they are understood not as an appearance of the saint but only as a visualization of the holy persons for the support of recollecting spiritual meanings that have been expounded intellectually through sermons. Hence, this led to an essentially instructional and aesthetic concept of images. The Western Church also viewed images as the Holy Scriptures’ substitute for the illiterate—i.e., for the overwhelming majority of church people in this period. Images thus became the Bible for the laity. Pope Adrian I, who encouraged Western recognition of the iconodulic Council of Nicaea, also referred to the perspicuity of the icons. This idea of perspicuity—i.e., the appeal to one’s imagination to picture the biblical persons and events to oneself—enabled him to recognize the Greek high esteem for the image without completely accepting the complicated theological foundation for icon veneration. The ideas articulated in the Libri Carolini remained decisive for the Western tradition. According to Thomas Aquinas, one of the greatest medieval theologians of the West, images in the church serve a threefold purpose: (1) for the instruction of the uneducated in place of books; (2) for illustrating and remembering the mystery of the incarnation; and (3) for awakening the passion of devotion, which is kindled more effectively on the basis of viewing than through hearing.
In the Western theology of icons, the omnipotence of the two-dimensionality of church art also was abandoned. Alongside church pictorial painting, ecclesiastical plastic arts developed; even painting in the three-dimensional form was introduced through the means of perspective. Art, furthermore, became embedded in the entire life of personal religiosity. The holy image became the devotional image; the worshiper placed himself before an image and became engrossed in his meditation of the mysteries of the Christian revelation. As devotional images, the images became the focal points for contemplation and mystical representation. Conversely, the mystical vision itself worked its way back again into pictorial art, in that what was beheld in the vision was reproduced in church art. The burden of ecclesiastical tradition, which weighs heavily upon Byzantine art, has been gradually abolished in the Western Church. In the Eastern Church the art form is just as fixed as ecclesiastical dogma; nothing may be changed in the heavenly prototypes. This idea plays little or no role in the West. There, religious art adjusts itself at any given time to the total religious disposition of the church, to the general religious mental posture, and also to religious needs. Religious art in the West also has been shaped by the imaginative fantasy of the individual artist. Thus, from the outset, a much more individual church art developed in the West. Thus, it became possible to dissociate sacred history from its dogmatic milieu and to transpose it from the past into the actual present, thereby allowing for an adaptable development of ecclesiastical art.
