Worship Modern Controversy

Iconodulism (Icon Veneration)

Religious images are legitimate aids to worship, affirmed at the Second Council of Nicaea in 787.

The Story

For most of Christian history, the painted face of Christ has been an ordinary feature of the room in which Christians pray. Catacomb frescoes from the third century already show Christ as the Good Shepherd; by late antiquity, portable panel icons of Christ, the Virgin, and the saints were kissed, bowed before, and carried in procession across the Byzantine world. To their defenders, these images were not decoration but a form of access — a window through which honor passed to the holy person depicted.

In the eighth century this practice met a fierce reaction. Beginning under the emperor Leo III and intensifying under his son Constantine V, the Byzantine state launched a campaign to remove and destroy religious images, the movement we now call iconoclasm. Icons were whitewashed, defenders were exiled or maimed, and the matter was framed as nothing less than whether Christians had been committing idolatry for centuries.

The decisive answer came at the Second Council of Nicaea in 787, convened under the empress Irene. The council restored the images and, crucially, drew a distinction it claimed had always been implicit: icons were to receive veneration or honorable reverence (in Greek, proskynesis), but never the true worship or adoration (latreia) that belongs to God alone. The theology that won the day owed much to John of Damascus, who had argued a generation earlier that the Incarnation itself licensed the image: God, once invisible, had taken visible flesh.

Nicaea II is counted by the Eastern Orthodox and the Catholic Church as the seventh ecumenical council, and its restoration of the icons is still celebrated annually in Orthodoxy as the “Triumph of Orthodoxy.” Yet its reception was never universal. The Frankish church, working from a flawed Latin translation of the acts, pushed back in the Libri Carolini, and the question of images would erupt again, with new ferocity, in the Protestant Reformation.

Today iconodulism remains the settled practice of the Eastern and Oriental Orthodox churches and of Catholicism, and images are retained and used devotionally in much of Lutheranism and Anglicanism. But to a large swath of Reformed, Baptist, and other Protestant Christians — and to Biblical Unitarians who read the second commandment strictly — the bowing Christian still looks uncomfortably like the idolater the prophets denounced.

Who Draws the Line

There is no council that condemns icon veneration as such; the conciliar weight runs the other way, with Nicaea II affirming it. The contest, rather, is between traditions that received that council and those that did not.

The Eastern Orthodox and Catholic churches hold that Nicaea II is binding and that veneration is not merely permitted but proper. They lean on the proskynesis–latreia distinction: the council taught that “the honor paid to the image passes to the prototype,” so that one who venerates an icon honors the person depicted, not the wood and paint. Reverence, on this account, is no more idolatrous than kissing a photograph of an absent friend.

The Reformed tradition draws the line in the opposite place, and does so on the authority of Scripture read through the second commandment (Exodus 20:4–5, on the traditional Reformed numbering). The Heidelberg Catechism (1563) treats images of God as forbidden and is wary even of images used to teach the laity. The Westminster Confession (1646) lists worship “by images” among things contrary to the regulative principle that worship must be positively commanded by God. For these churches the proskynesis–latreia distinction is a fine line that ordinary devotion cannot reliably hold.

The Lutheran and Anglican positions sit in between and resist easy summary. Lutherans, following Luther’s quarrel with the iconoclast Andreas Karlstadt, retained crucifixes and images as adiaphora — things neither commanded nor forbidden, useful for memory and teaching. The Church of England retained images in its architecture but, in Article XXII of the Thirty-Nine Articles, named “worshipping and adoration as well of images as of relics” a “fond thing vainly invented.” So even among the traditions that keep their images, formal veneration of them is something many explicitly refuse. Biblical Unitarians, for their part, tend to side with the strict reading, seeing in the whole apparatus a drift away from the unmediated worship of the one God.

Why You Might Accidentally Believe This

The most natural route runs straight through the Incarnation. If you confess that the invisible God became visible in a particular Galilean man — that he had a face, a height, a color, a shape — then depicting that face can seem not only permissible but almost required by the logic of the gospel. To refuse the image, John of Damascus argued, is to flinch at the very flesh-taking that the gospel proclaims. Many Christians arrive here without ever hearing the word “iconodulism”: they simply find a crucifix or a painting of Christ helps them pray, and cannot see what the harm could be.

A second route is the ordinariness of honoring through objects. We salute flags, kiss photographs, lay flowers at graves, and treasure a parent’s wedding ring — and in none of these do we imagine we are worshipping cloth, paper, stone, or metal. If reverence directed at an object can pass through it to a person, then bowing before an icon of Christ feels continuous with how human love and memory already work. The leap from “I honor this picture of my grandmother” to idolatry seems, from the inside, like no leap at all.

The Strongest Case For This View

The strongest argument is christological. Colossians 1:15 calls Christ “the image (Greek eikon) of the invisible God.” Defenders press the irony — the New Testament itself names the Son an eikon, the very word from which “icon” descends. The God whom no one has seen (John 1:18) has now been “made known” in the visible Son. If God himself supplied the definitive image of the invisible, the argument runs, then the prohibition on images cannot be absolute; it must concern false gods and idols, not the depiction of the God who chose to be seen.

From here the patristic case builds. John of Damascus, writing around 730, conceded that under the old covenant images of the unseen God were rightly forbidden — precisely because God had no form to depict. But “now,” he wrote, “when God is seen clothed in flesh,” the situation has changed: “I do not worship matter, I worship the God of matter, who became matter for my sake.” On this reading, iconoclasm is not merely a liturgical mistake but a christological one, an embarrassed retreat from the reality of the enfleshment.

The honor-and-prototype principle does real work too. Nicaea II insisted that veneration terminates not on the image but on the one imaged — “the honor paid to the image passes to the prototype,” a line the council drew from Basil of Caesarea’s reflection (in On the Holy Spirit) on how an emperor’s portrait is honored without doubling the number of emperors. Defenders add that Scripture itself records divinely commanded religious imagery: the cherubim made for the ark and the mercy seat (Exodus 25:18–22), and the bronze serpent Moses was told to make and lift up (Numbers 21:8–9). A flat prohibition on all sacred images, they argue, cannot be squared with a God who commanded some.

The Strongest Case Against

The case against starts with the plain words of the second commandment: “You shall not make for yourself a carved image … you shall not bow down to them or serve them” (Exodus 20:4–5). The prohibition couples making with bowing, and bowing is exactly what veneration involves. Critics argue that the proskynesis–latreia distinction, however precise on paper, is not a distinction that the kneeling worshipper or the kissing pilgrim actually feels — and that the commandment was given precisely because the human heart slides so easily from honor to worship.

Deuteronomy 4 sharpens the point in a way defenders find hardest to answer. Israel is reminded that at Horeb “you saw no form of any kind” — therefore they must make no image, lest they corrupt themselves (Deuteronomy 4:15–16). The argument is not that God could not be depicted but that the absence of a seen form was itself the warning. Critics contend the Incarnation does not cancel this: what was seen in Christ was his humanity, and an icon of that humanity risks presuming to circumscribe what remains uncircumscribable. This was, in fact, the iconoclasts’ own christological charge — that any image of Christ either divides his two natures or confounds them.

There is also the brute historical anxiety. The prophets did not condemn idolatry as a crude theological error made by people who thought the wood was a god; they condemned a sophisticated cult whose practitioners would also have insisted the honor passed through the image to the deity. If the very thing the prophets attacked can be redescribed as legitimate veneration, the Reformed and Unitarian worry goes, then the second commandment has been defined down to nothing. Better, they argue, to keep worship imageless and let the God who is spirit be worshipped “in spirit and truth” (John 4:24).

What the New Testament Actually Says

The honest answer is that the New Testament neither commands nor forbids religious images, and never addresses the practice of venerating them at all. There were no Christian icons to argue about in the first century; the entire debate is an inference from texts written before the question arose. This silence is itself a datum, and both sides claim it. Defenders note that the New Testament never repeats the second commandment’s image-prohibition as binding on Gentile believers, even where it does warn, repeatedly, against “idols” (1 John 5:21; 1 Corinthians 10:14). Critics reply that those same warnings against idolatry are frequent and severe, and that the apostolic world was thoroughly Jewish in its instinctive horror of cult images.

The christological texts the defenders prize do real but limited work. Colossians 1:15 and 2 Corinthians 4:4 call Christ the eikon of God, and John 1:18 and 14:9 press the theme that to see Jesus is to see the Father. These passages establish that God has, in Christ, given himself to be known visibly — but they say nothing about whether painted representations of that visible Son may be made, still less venerated. The leap from “Christ is the image of God” to “therefore images of Christ may be honored” is a theological construction, not an exegetical given.

So the New Testament underdetermines the question almost completely. It supplies the raw material — a God now made visible, and a standing horror of idolatry — without telling us how to weigh them once Christians began to paint. Where you come down depends less on a verse than on which danger you think more pressing: the gnostic-tinged refusal of the flesh that defenders fear, or the slide into idolatry that critics fear. The text leaves both fears standing.
