Icon Veneration

History

Causes

Christian art is older than any defence of it. Catacomb paintings, the third-century house church at Dura-Europos and early mosaics show that believers pictured Christ, Jonah and the shepherd long before anyone argued that they should. What forced an argument was the growth of devotion to particular images in the sixth and seventh centuries, and then the imperial attempt to stop it.

When Leo III ordered images destroyed in 726 and the council of Hieria condemned them in 754, the defenders had to produce a theology on short notice. John of Damascus, writing safely outside the empire under Muslim rule, supplied it in his Three Treatises on the Divine Images (c. 730). He made two moves that have carried the position ever since. The first distinguishes the worship owed to God alone from the reverence given to what is holy. The second answers the second commandment with the incarnation: the God who could not be pictured has taken flesh, and to refuse to picture him is to doubt that he did. He also borrowed Basil’s rule, framed originally for the Son’s relation to the Father, that “the honour paid to the image passes on to the prototype” (On the Holy Spirit 18; Exact Exposition 4.16).

Influence

The Second Council of Nicaea in 787 made the position the church’s official teaching. Its definition orders that images “should be given due salutation and honourable reverence, not indeed that true worship of faith which pertains alone to the divine nature,” and grounds the practice in the rule that “the honour which is paid to the image passes on to that which the image represents” (definition). Theodore the Studite carried the argument through the second iconoclast period, and the restoration of the icons in 843 is still kept as the Triumph of Orthodoxy on the first Sunday of Lent.

For the Eastern Orthodox churches the icon became more than permitted art. It is treated as a form of theology and a point of contact with the saint it shows, kissed on entering a church and carried in procession. The Roman Catholic Church holds the same principle with less liturgical weight, and the Catechism (§2129–2132) restates Nicaea almost word for word. Oriental Orthodox churches, outside the empire during the controversy, kept their own image traditions and were never iconoclast.

The Western reception was uneven from the start. Charlemagne’s court had the Libri Carolini (mid-790s, secondary) written to refute Nicaea II on sacred images, and the Frankish bishops held a middle position for generations. The Reformation revived the objection in earnest, and the Council of Trent answered it in its twenty-fifth session (1563): before images “we venerate the saints, whose similitude they bear: as, by the decrees of Councils, and especially of the second Synod of Nicaea, has been defined against the opponents of images.”

Key ideas and contributors

The incarnation changes what can be depicted. This is the heart of the case. The second commandment forbade images of a God who had shown no form; in Christ, God has shown one. John of Damascus argued that refusing to depict the incarnate Christ denies the reality of his flesh, which is why the dispute is classed with the christological controversies and settled by an ecumenical council rather than a local synod.

Veneration is not worship. Nicaea II made the distinction explicit in Greek: images receive proskynesis, salutation or reverence, while latreia, the worship of faith, “pertains alone to the divine nature” (definition). The council noted that Scripture tells us to serve God only, and reasoned that veneration is a word of wider meaning than service.

The honour passes to the prototype. Basil’s formula does the work. Reverence shown to an image is not directed at wood and paint but travels to the person imaged, as honour shown to a king’s portrait is honour to the king. Nicaea II quotes it, John of Damascus quotes it, and so does the Catechism (§2132).

The Old Testament already has images. God commanded the cherubim over the ark and the bronze serpent, and Israel honoured a tabernacle that bore “an image and type of heavenly things” (Exodus 25:18–20; Exact Exposition 4.16). The argument is that the commandment forbids idols, not images.

Tradition. The council presents itself as “holding fast the traditions which we have received,” and treats the practice of the churches as evidence of apostolic teaching (Holy Tradition). This is also where the disagreement with Sola Scriptura becomes unavoidable: the case for icons rests partly on what the church has long done.

Other contributors: Germanus of Constantinople, the patriarch who resisted Leo III and resigned; Theodore the Studite, whose Antirrhetics answered the second wave of iconoclasm; and the empress Irene and the patriarch Tarasius, who convened Nicaea II.

Key controversies

The second commandment. The plain reading of Exodus 20:4–5 forbids both making and bowing to images. Iconoclasts and after them the Reformed churches argue that no distinction between veneration and worship survives contact with actual practice. John Calvin answered the whole case in the Institutes 1.11, and the Heidelberg Catechism (Q96–98) made the denial confessional.

Can Christ be painted at all? The iconoclasts’ sharpest argument was christological: a painter depicting Christ must either separate his humanity from his divinity or claim to circumscribe the uncircumscribable. Nicaea II answered that an icon depicts a person, not a nature, and that the person depicted is the incarnate Word. Critics still ask whether the answer works, since the same person is God.

What the council actually decided. The Frankish bishops rejected Nicaea II in the Libri Carolini, and the Western reception of the council was partial for centuries. Protestant writers have argued that the council’s distinctions were a late rationalisation of a practice that had already outgrown them.

Silence of the early church. Iconoclasts quoted Eusebius of Caesarea and Epiphanius of Salamis against images, and defenders disputed the texts. The historical question is live in modern scholarship too, since iconoclast writings survive only as quotations inside the documents that refute them.

Statues and the West. Orthodox practice is restricted to two-dimensional images; Western Catholicism developed three-dimensional statuary. Some Orthodox writers treat this as a departure, and Protestant polemic has often aimed at statues rather than icons.

What remains unresolved

Everyone in the argument agrees that God alone may be worshipped. The open question is whether an act of reverence can be reliably aimed past the object at the person, or whether the attempt collapses in practice. That is a question about human beings as much as about theology, and it is why the dispute has outlived every council that has settled it.
