Religious images in Christian theology
Religious images in Christian theology have a role within the liturgical and devotional life of adherents of certain Christian denominations. The use of religious images has often been a contentious issue in Christian history. Concern over idolatry is the driving force behind the various traditions of aniconism in Christianity. In the early Church, Christians used the Ichthys (fish) symbol to identify Christian places of worship and Christian homes. The Synod of Elvira (306 AD - 312 AD) "prohibited the exhibition of images in churches". However, since the 3rd century AD, images have been used within Christian  worship within parts of Christendom, although some ancient Churches, such as the Church of the East, have apparently long traditions of not using images. Certain periods of Christian history have seen supporters of aniconism in Christianity, first with the movement of Byzantine Iconoclasm, in which Eastern Orthodox and Byzantine Emperors Michael II, as well as Theophilos, "banned veneration of icons and actively persecuted supporters of icons." Later, during the Iconoclastic Fury, Calvinists removed statues and sacred art from churches that adopted the Reformed faith. Religious imagery today, in the form of statues, is most identified with the Roman Catholic and  Lutheran traditions. Icons are used extensively, and are most often associated with parts of Eastern Christianity, although they are also used by Roman Catholics, Lutherans, and, increasingly, Anglicans. Since the 1800s, devotional art has become very common in Christian homes, both Protestant and Catholic, often including wall crosses, embroidered verses from the Christian Bible, as well as imagery of Jesus. In Western Christianity, it is common for believers to have a home altar, while dwelling places belonging to communicants of the Eastern Christian Churches often have an icon corner. A cult image is a human-made object that is venerated  or worshipped for the deity, person or spirit that it embodies or represents. It is also controversially and pejoratively used by some Protestants to describe the Eastern Orthodox (and, to a lesser extent, Catholic) practice of worshipping the Christian God through the use of icons, a charge which these Christians reject. In a similarly controversial sense, it is also used by some Protestants to pejoratively describe various Catholic devotional practices such as scapulars and the veneration of statues and flat images of the Virgin Mary and other saints, which Catholics do not consider idolatry. Jewish origins. Idolatry is prohibited by  many verses in the Old Testament, but there is no one section that clearly defines idolatry. Rather there are a number of commandments on this subject spread through the books of the Hebrew Bible, some of which were written in different historical eras, in response to different issues. Idolatry in the Hebrew Bible is defined as the worship of idols (or images); the worship of polytheistic gods by use of idols (or images) and even the use of idols in the worship of Yahweh (God). The Israelites used various images in connection with their worship, including carved cherubim on the  Ark of the Covenant () which God instructed Moses to make, and the embroidered figures of cherubim on the curtain which separated the Holy of Holies in the Tabernacle tent (). Similarly, the Nehushtan, which God commanded Moses to make and lift high to cure any Israelites who looked at it of snakebites, is God-ordained use of an image. However, as part of a later religious reform Hezekiah destroyed the Serpent, which the Hebrew people had been burning incense to (). New Testament. Judaism's animosity towards what they perceived as idolatry was inherited by Jewish Christianity. Although Jesus discussed the Mosaic  Law in the Sermon on the Mount, he does not speak of issues regarding the meaning of the commandment against idolatry. His teachings, however, uphold that worship should be directed to God alone (Matthew 4:10 which is itself a quote of Deuteronomy 6:13, see also Shema in Christianity, Great Commandment, and Ministry of Jesus). The Pauline Epistles contain several admonitions to "flee from idolatry" (, , , , , , ) A major controversy among Early Christians concerned whether it was permissible to eat meat that had been offered in pagan worship. Paul of Tarsus, who agreed to the Apostolic Decree, also wrote that it was permitted  to do so, as long as a blessing was pronounced over it, and provided that scandal was not caused by it. However, he said that the gods worshiped in idolatry were in his belief demons, and that any act of direct participation in their worship remained forbidden (1 Corinthians 10:14-22). See also the Law of Christ. The New Testament also uses the term "idolatry" to refer to worship like passion for things such as wealth, as in Colossians 3:5, "Put to death, therefore, whatever belongs to your earthly nature: sexual immorality, impurity, lust, evil desires and greed which is  idolatry." Some Christian theologians see the absolutization of an idea as idolatrous. Therefore, undue focus on particular features of Christianity to the exclusion of others would constitute idolatry. The New Testament does contain the rudiments of an argument which provides a basis for religious images or icons. Jesus was visible, and orthodox Christian doctrine maintains that Jesus is YHWH incarnate. In the Gospel of John, Jesus stated that because his disciples had seen him, they had seen God the Father (Gospel of John 14:7-9 ). Paul of Tarsus referred to Jesus as the "image of the invisible God" (Colossians 1:15 ). Theologians such as John of Damascus argued that the connection between Jesus' incarnation and the use of images is so strong that to reject or prohibit the use of images is tantamount to denying the Incarnation of Jesus. Early Christianity grew in a society where religious images, usually in the form of statues, both large ones in temples and small ones such as lares and penates in the home, were a prominent feature of traditional pagan religions, such as traditional Ancient Roman religion, Ancient Greek religion and other forms of Eastern paganism. Many writings by Church fathers contain strong denunciations  of these practices, which seem to have included outright idol-worship. Statues on secular buildings, however, could serve as expression of secular power in various periods of Christianity, without implications of idol-worship. The use of icons and symbols in Christian worship. Early Christian art used symbolic and allegorical images mainly, partly no doubt to avoid drawing attention during the persecution of early Christians in the Roman Empire. In the Catacombs of Rome Jesus was represented indirectly by pictogram symbols such as the Ichthys ("fish"), peacock, Lamb of God, or an anchor (the Labarum or "Chi-Rho" was a later  development). Later, personified symbols were used, including Jonah, whose three days in the belly of the whale pre-figured the interval between Christ's death and Resurrection, Daniel in the lion's den, or Orpheus charming the animals. The image of "The Good Shepherd", a beardless youth in pastoral scenes collecting sheep, was the most common of these images, and was probably not understood as a portrait of the historical Jesus. The depiction of Jesus already from the 3rd century included images very similar to what became the traditional image of Jesus, with a longish face and long straight hair . As the Church increased in size and popularity, the need to educate illiterate converts led to the use of pictures which portrayed biblical stories, along with images of saints, angels, prophets, and the Cross (though only portrayed in a bejewelled, glorified state). After the end of persecution, and the adoption of Christianity by Constantine, large churches were built and from the start decorated with elaborate images of Jesus and saints in mosaic. Small carved reliefs were also found on sarcophagi like the Sarcophagus of Junius Bassus. However large monumental sculpture of religious subjects was not produced, and in Byzantine art  and Eastern Orthodox art it is avoided to the current day. It only reappeared in Carolingian art, among peoples who had no memory of pagan religious statues. Paintings of Old Testament scenes are found in Jewish catacombs of the same period, and the heavily painted walls of Dura Europos Synagogue in Syria. Catholic and Orthodox historians affirm, on the basis of these archeological finds in the Catacombs, that the veneration of icons and relics had begun well before Constantine I. Christian use of relics also dates to the catacombs, when Christians found themselves praying in the presence of the bodies  of martyrs, sometimes using their tombs as altars for sharing the Eucharist, which was, and in Catholicism, Lutheranism and Eastern Orthodoxy is, the central act of Christian worship. Many stories of the earliest martyrs end with an account of how Christians would gather up the martyr's remains, to the extent possible, in order to retain the martyr's relics. This is shown in the written record of the martyrdom of Saint Polycarp, a personal disciple of Saint John the Apostle. Significant periods of iconoclasm (deliberate destruction of icons) have occurred in the history of the Church, the first major  outbreak being the Byzantine iconoclasm (730-787), motivated by a strictly literal interpretation of the second commandment and interaction with Muslims who have a very strict teachings against the creation of images. Iconoclasm was officially condemned by the Western and Eastern Churches at the Second Council of Nicaea in 787 AD (the Western Church was not represented, but approved the decrees later). This decision was based on the arguments including that the biblical commandment forbidding images of God was because no-one had seen God. But, by the Incarnation of Jesus, who is God incarnate in visible matter, humankind has  now seen God. It was therefore argued that they were not depicting the invisible God, but God as He appeared in the flesh. The Libri Carolini are a response prepared in the court of Charlemagne, when under the mistaken impression that the Nicea Council had approved the worship as opposed to the veneration of images. Different understandings of the use of images. Catholics use images, such as the crucifix, the cross, in religious life and pray using depictions of saints. They also venerate images and liturgical objects by kissing, bowing, and making the sign of the cross. They point to  the Old Testament patterns of worship followed by the Hebrew people as examples of how certain places and things used in worship may be treated with reverence or venerated, without worshiping them. The Ark of the Covenant was treated with great reverence and included images of cherubim on top of it (), and certain miracles were associated with it, yet this was not condemned. Christianity interprets the commandment not to make "any graven image, or any likeness of any thing that is in heaven above" to mean to not "bow down and worship" the image in and of itself nor a  false god through the image. Christian theology offers the following explanations of liturgical practice that features images, icons, statues, and the like: A recent joint Lutheran-Orthodox statement made in the 7th Plenary of the Lutheran-Orthodox Joint Commission, in July 1993 in Helsinki, reaffirmed the Ecumenical Council decisions on the nature of Christ and the veneration of images: 7. As Lutherans and Orthodox we affirm that the teachings of the ecumenical councils are authoritative for our churches. The ecumenical councils maintain the integrity of the teaching of the undivided Church concerning the saving, illuminating/justifying and glorifying acts of  God and reject heresies which subvert the saving work of God in Christ. Orthodox and Lutherans, however, have different histories. Lutherans have received the Nicaeno?Constantinopolitan Creed with the addition of the filioque. The Seventh Ecumenical Council, the Second Council of Nicaea in 787, which rejected iconoclasm and restored the veneration of icons in the churches, was not part of the tradition received by the Reformation. Lutherans, however, rejected the iconoclasm of the 16th century, and affirmed the distinction between adoration due to the Triune God alone and all other forms of veneration (CA 21). Through historical research this council has  become better known. Nevertheless it does not have the same significance for Lutherans as it does for the Orthodox. Yet, Lutherans and Orthodox are in agreement that the Second Council of Nicaea confirms the christological teaching of the earlier councils and in setting forth the role of images (icons) in the lives of the faithful reaffirms the reality of the incarnation of the eternal Word of God, when it states: "The more frequently, Christ, Mary, the mother of God, and the saints are seen, the more are those who see them drawn to remember and long for those who serve  as models, and to pay these icons the tribute of salutation and respectful veneration. Certainly this is not the full adoration in accordance with our faith, which is properly paid only to the divine nature, but it resembles that given to the figure of the honored and life?giving cross, and also to the holy books of the gospels and to other sacred objects" (Definition of the Second Council of Nicaea). Martin Luther defended the use of "importance of images as tools for instruction and aids to devotion". He stated that "If it is not a sin but good to have  the image of Christ in my heart, why should it be a sin to have it in my eyes?" He permitted the commissioning of new Lutheran altarpieces, including those of the Last Supper. The "Schneeberg Altarpiece" was placed at the high altar of St. Wolfgang im Salzkammergut and as Lutheran sacred imagery, reflects "the devotional forms of fifteenth- and early sixteenth century northern art". Lutheran sacred art, however, gained a new function in addition to exciting one's mind to thoughts of the Divine by also serving a didactic purpose. Writing for the United Methodist Church, Tricia Brown discusses  the importance of sacred art: The Methodist Modern Art Collection is housed by the Methodist Church of Great Britain, and the Secretary of the Methodist Conference, the Revd Canon Gareth J Powell, writes that it features "vibrant expressions of God's love, and a whole range of conversations that are both missional and pastoral". Calvinist criticism. John Calvin, the progenitor of the Reformed tradition of Christianity that influenced the Continental Reformed, Congregational, Anglican and Presbyterian traditions, was always extremely hostile to all publicly displayed religious images, which were systematically destroyed by Calvinists, as in the Beeldenstorm in the Netherlands. Towards  the end of the 16th century there were disputes between Lutherans and Calvinists, with the Lutherans offering strong opposition to Calvinist iconoclasm. Though both groupings did not object to book illustrations or prints of biblical events, or portraits of reformers, production of large-scale religious art virtually ceased in Protestant regions after about 1540, and artists shifted to secular subjects, ironically often including revived classical mythology. The earliest catechisms of Reformed (Calvinist) Christianity, written in the 16th through 18th centuries, including the Heidelberg (1563), Westminster (1647) and Fisher's (1765), included discussions in a question and answer format detailing how  the creation of images of God (including Jesus) was counter to their understanding of the Second Commandment's prohibition against creating images of worship in any manner. 20th century Calvinist theologian J. I. Packer, in Chapter 4 of his book "Knowing God", writes that, "Imagining God in our heads can be just as real a breach of the second commandment as imagining Him by the work of our hands." His overall concern is that "The mind that takes up with images is a mind that has not yet learned to love and attend to God's Word." In other words , image making relies on human sources rather than on divine revelation. Another typical Christian argument for this position might be that God was incarnate as a human being, not as an object of wood, stone or canvas, and therefore the only God-directed service of images permitted is the service of other people. During the period of Archbishop William Laud's conflicts with Puritans within the Church of England, the use of ritual implements prescribed by the "Book of Common Prayer" was a frequent cause of conflict. (See vestments controversy) Non-use by Amish. The Amish are an Anabaptist Christian  group that forbids the use of images in secular life. In their critiques these groups argue that such practices are in effect little different from idolatry, and that they localize and particularize God, who, they argue, is beyond human depiction. Differentiation from idolatry. Idolatry is consistently prohibited in the Hebrew Bible, including as one of the Ten Commandments () and in the New Testament (for example , most significantly in the Apostolic Decree recorded in ). There is a great deal of controversy over the question of what constitutes idolatry and this has bearing on the visual arts and the use of icons  and symbols in worship, and other matters. As in other Abrahamic religions the meaning of the term has been extended very widely by theologians. The "Catechism of the Catholic Church" states: "Idolatry not only refers to false pagan worship...Man commits idolatry whenever he honours and reveres a creature in place of God, whether this be gods or demons (for example satanism), power, pleasure, race, ancestors, the state, money etc." Speaking of the effects of idolatry, Benedict XVI says, "Worship of an idol, instead of opening the human heart to Otherness, to a liberating relationship that permits the person to  emerge from the narrow space of his own selfishness to enter the dimensions of love and of reciprocal giving, shuts the person into the exclusive and desperate circle of self-seeking"
