Why do Catholics use images and statues?

The objection is found in the Decalogue. It must be taken in its full force before it is answered.

The text of the commandment

The book of Exodus is categorical:

“You shall not make for yourself a graven image, or any likeness of anything that is in heaven above, or that is on the earth beneath, or that is in the water under the earth. You shall not bow down to them or serve them.” — Exodus 20:4-5, Jerusalem Bible^[1]

At first sight, the verdict seems final: every image is forbidden, and the Catholic kneeling before a statue is caught red-handed. That is how the Byzantine iconoclasts read it, and then, at the Reformation, Karlstadt and Reformed iconoclasm, which emptied entire churches of their statues. But neither Luther nor Calvin holds every image to be illicit: Luther opposes this iconoclasm — sermons of the Invocavit at Wittenberg (March 1522), then Against the Heavenly Prophets (1524-1525) — and teaches that the Law forbids only the image of God that is worshiped, not a crucifix; Calvin, likewise, refuses to hold every representation to be illicit (Institutes, I, 11, 12)^[2]. The Reformed objection, in its strong form, stands and deserves an answer: no image of God, and no image in worship — for the image, it says, captures the worship due to God alone.

The Hebrew word points first to the statue

Precision matters here, because the word counts. The Hebrew term translated as “sculpted image” (RSV: “graven image”) is pesel (פֶּסֶל), which means very exactly a carved image, cut from wood or stone, cast in metal — in other words a statue^[3]. The commandment — the first in the Catholic numbering, the second among Jews and the Reformed — therefore targets in the first place sculpture, the three-dimensional object set up before which men bow down. And the verse immediately adds “any likeness” (kol temunah, every representation, including painted ones): the ban therefore also covers the painted image. This is precisely the apparently most embarrassing case for Catholicism, the plaster statue in the corner of a chapel.

So the objection carries its full weight. If the commandment forbids every pesel, then a statue of the Virgin falls under the ban. Everything depends on what the commandment really forbids: sculpture as such, or sculpture worshiped as a god?

What the commandment condemns: the idol, not representation

The key lies in the sentence that immediately follows: “You shall not bow down to them or serve them.” The commandment does not stop at the making of an image; it targets the image held to be a god and given worship. The context confirms it: the first commandment is directed entirely against the polytheism and idolatry of the nations, those peoples who worshiped statues of Baal, Astarte, or Moloch, believing that the divinity dwelt in the wood and the stone^[4].

The idol, in the biblical sense, is not a mere statue: it is a divinized creature, credited with a divine power and given a worship that belongs to God alone. The psalmist mocks them: “Their idols, silver and gold, a work of human hands! They have mouths and do not speak, they have eyes and do not see” (Ps 115:4-5, Jerusalem Bible). What God forbids is confusing the Creator with the work of our hands. An image that claims no divinity, receives no worship of adoration, and instead points back to the true God is not an idol: it is its opposite.

How can we be sure? By a proof the objection always forgets: God himself ordered statues.

If the first commandment forbade every representation, then God would contradict himself a few chapters later — which is impossible. Yet in the same book of Exodus, and by the same mouth, God orders figures to be sculpted for his own sanctuary. The Catechism notes this explicitly:

“Nevertheless, already in the Old Testament, God ordained or permitted the establishment of images that would symbolically point toward salvation by the incarnate Word: such as the bronze serpent, the ark of the covenant, and the cherubim.” — Catechism of the Catholic Church, § 2130^[5]

Three examples suffice, and they are unanswerable.

The golden cherubim of the Ark

At the very moment he gives the tables of the Law, God commands Moses to make two statues of angels in solid gold:

“You shall make two cherubim of beaten gold, you shall make them at the two ends of the mercy seat. [...] The cherubim shall spread out their wings above and shelter the mercy seat with their wings, facing each other.” — Exodus 25:18-20, Jerusalem Bible^[6]

These are three-dimensional images — statues — of heavenly creatures, placed at the heart of the Holy of Holies, the most sacred place in Israel, where God manifested his presence. The same God who has just forbidden “sculpted images” therefore orders sculptures for his own throne. The contradiction is only apparent: what he forbids is the idol; what he commands is the image placed at the service of the worship of the true God.

The bronze serpent, a statue that saves

The most striking example is the bronze serpent. The people, bitten by serpents in the desert, are saved by a statue that God himself orders Moses to set up:

“Fashion for yourself a Fiery One which you shall place on a standard. Whoever has been bitten and looks at it shall live.” — Numbers 21:8, Jerusalem Bible^[7]

A bronze statue becomes here the visible instrument of God's salvation — and Christ himself will take up the image to announce his Cross: “As Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up” (Jn 3:14, Jerusalem Bible)^[8]. But the story has a decisive sequel: centuries later, King Hezekiah destroys this same bronze serpent, because the people had begun burning incense to it as to a god (2 Kgs 18:4)^[9].

The contrast is luminous. The serpent was legitimate as long as it pointed back to God; it becomes an idol the day it is worshiped for itself. It is not the object that changes, but the heart of man. Here is the whole Catholic doctrine of the image, summed up by a single biblical object: a statue can be holy or idolatrous according to the use made of it.

The sculptures of Solomon's Temple

Finally, the Temple of Jerusalem, built on plans approved by God, was covered with sculptures: cherubim of gilded wood several meters high, palm trees, flowers, and twelve bronze oxen bearing the great basin of ablutions (1 Kgs 6:23-29; 7:25)^[10]. The holiest place of Judaism was a museum of sculptures — and no prophet saw idolatry in it, because none of it was worshiped.

The conclusion imposes itself: the Bible does not condemn sculpture, it condemns the idol. It remains to understand why Christianity, far from merely accepting this ancient permission, made the image a central element of its faith. The answer is one word: the Incarnation.

Under the Old Covenant, a certain caution surrounded the image of God, for a simple reason, stated by Deuteronomy: no one had seen God. “Take good heed to yourselves: since you saw no form on the day Yahweh spoke to you at Horeb out of the midst of the fire” (Dt 4:15, Jerusalem Bible). Depicting the invisible risked reducing him to an idol. But with the New Testament, everything changes.

“And the Word became flesh”

Saint John's prologue states the event on which all Christian imagery is founded:

“And the Word became flesh and dwelt among us, full of grace and truth; we have beheld his glory.” — John 1:14^[11]

The God whom no one had ever seen gave himself a face. In Jesus of Nazareth, the invisible became visible, tangible, depictable. Saint Paul calls Christ “the image (eikôn) of the invisible God” (Col 1:15)^[12] — and the Greek word eikôn is the very root of the word icon. Jesus himself says to Philip: “He who has seen me has seen the Father” (Jn 14:9)^[13]. From then on, painting or sculpting Christ is no longer an audacity: it is a consequence of faith in his real humanity.

Saint John Damascene: “I do not venerate the matter...”

This is what the great defender of images in the eighth century, Saint John Damascene, magnificently formulated when the Byzantine emperor sought to destroy all the icons:

“I do not venerate the matter, but the Creator of matter, who became matter for my sake, who deigned to dwell in matter and who, through matter, worked my salvation.” — Saint John Damascene, Discourse against those who reject the holy images, I, 16^[14]

The argument is formidably profound: refusing every sacred image is not merely a question of art, it is quietly denying the Incarnation. For if God truly became flesh, then matter is no longer unworthy of bearing him — and an absolute ban on depicting him would amount to saying he never truly became man. The Christian image is thus the visible seal of a central mystery of the faith, the Incarnation. It is found from the early third century, long before the councils: Christians were already painting the Good Shepherd and biblical scenes on the walls of the catacombs of Rome^[15].

So much for legitimacy. But the real question of the title lies elsewhere: why do Catholics use them so much? An image is not decorative; it does something. This contribution can be grouped into four functions — a grouping made by this article, informed by three sources of tradition^[16].

Teaching: catechesis for the eyes

The first function is pedagogical. For centuries when the vast majority of the faithful could not read, the images in churches were their Bible. Pope Saint Gregory the Great formulated it once and for all, in a famous letter to a bishop who had destroyed the images in his diocese:

“What writing offers to those who can read, painting supplies to the illiterate who look at it; for in it the ignorant see what they should follow, in it those who do not know letters read.” — Saint Gregory the Great, Letter to Serenus of Marseilles (c. 600)^[17]

A statue of the Nativity, a Way of the Cross, a stained-glass window of the Last Judgment teach in a single glance what a sermon takes an hour to say. Even today, a child understands the Passion by following the fourteen stations before he can even read the Gospel.

Keeping memory: making the mystery present

The image recalls. Just as we keep the photograph of a loved one, Christians surround their lives with the faces of Christ, the Virgin, and the saints so as not to forget them amid worldly affairs. The statue has no power in itself, but it tears us away from distraction: passing before a crucifix means remembering, in a second, the price of our salvation. This is the function already fulfilled for Israel by the memorial stones raised after crossing the Jordan (Jos 4:6-7).

Lifting up: from the statue to the model

Third function, the most delicate. The sacred image is a springboard: the gaze does not stop at it but passes through it to rise toward the one it depicts. This is the great principle defined by the Second Council of Nicaea in 787, taken up by the Catechism:

“The honor paid to an image passes to its prototype, and whoever venerates an image venerates in it the person portrayed in it.” — Catechism of the Catholic Church, § 2132, citing Nicaea II and Saint Basil^[18]

Saint Thomas Aquinas puts it in a limpid formula: “the movement toward the image as such does not stop at it, but tends toward the reality of which it is the image”^[19]. Before a statue of the Virgin, the believer does not think “here is God” nor even “here is sacred plaster”, but “here is she whom God has filled, and who prays for me.” The honor never stops at the object: it rises to the person, and through her to God.

Making us pray: the body prays too

Finally, the image moves us and helps the body pray. Man is not a pure spirit: he prays with his eyes, his knees, his hands. A beautiful statue, a sorrowful face of Christ on the cross, touch the heart where concepts cannot reach. That is why Catholics light a candle before a statue, carry a Madonna in procession, or kiss a crucifix: so many gestures of the body that sustain the prayer of the soul. On these concrete practices, see Why light candles? and Why go on pilgrimages?.

There remains the decisive objection: “Perhaps — but Catholics bow down before statues, kiss them, pray to them — is that not worship?” The answer lies in a distinction the whole tradition maintains with absolute rigor: we honor the image, we worship God alone.

The Council of Trent formulated it in direct reply to the Reformers:

“The images of Christ, of the Virgin Mother of God, and of the other saints are to be kept and honored, especially in churches [...] not because it is believed that there is any divinity or power in them [...], but because the honor shown to them is referred to the prototypes which they represent.” — Council of Trent, Session XXV (1563), free translation^[20]

No divinity dwells in the plaster; the statue neither hears, nor sees, nor can do anything. Catholics know this perfectly well. When they bow before an image, they attribute nothing to the object: they honor the person depicted, and that honor rises to God, the source of all holiness. The simplest proof that no statue is worshiped? The Church never offers sacrifice to an image.^[21] The one sacrifice, that of the Mass, is reserved for God alone — and sacrifice is the proper mark of worship.

The full distinction between worship (latria), veneration (dulia), and Marian hyperdulia is developed in What is the difference between worship and veneration? and Dulia, hyperdulia, and latria; it will not be repeated here. The essential can be said in one sentence: honoring a statue of the Virgin is not stealing something from God — it is honoring God in the most beautiful thing he has made.

The doctrine is no modern improvisation: it was fixed by the Magisterium at three great moments.

• The Second Council of Nicaea (787), the seventh ecumenical council, condemned iconoclasm and defined that images of Christ, the Virgin, and the saints are to be venerated, while clearly distinguishing “true worship (latreia), which befits the divine nature alone” from the “veneration of honor (timetike proskynesis)” given to images^[22]. The Catechism sums it up: “By becoming incarnate, the Son of God introduced a new ‘economy’ of images”^[23].
• The Council of Trent (1563) restated this doctrine against the Protestants, confirmed the honor due to images, while asking that popular abuses and superstitions be corrected^[24].
• The Second Vatican Council, in Sacrosanctum Concilium, maintained “the practice of displaying sacred images in churches for the veneration of the faithful,” asking that they be displayed “in restrained number and in fitting arrangement” — neither cluttered nor confusing^[25].

The Church has therefore never said that everything is permitted. It asks for images that are true, sober, and ordered toward God — and it condemns both idolatry and iconoclasm, those two symmetrical excesses.

“But some people pray before the statue!”

Praying before an image is not praying to the statue. The believer uses the image as a point of support to fix his attention — exactly as we look at a photograph while thinking of someone absent. His prayer is not addressed to the plaster, but to the person depicted, and through her to God — and nothing is asked of the image itself^[26]. The test is simple: ask this believer whether the statue itself answers him; he will reply no — it is God who answers; the statue only helps him pray.

“Some kiss the feet of statues!”

These gestures of affection — kissing, touching, decking a statue with flowers — belong to human tenderness, not divine worship. We kiss the photograph of a dead child without divinizing it; we kiss the foot of a crucifix to mark our love for the crucified Christ, not to worship wood. On Good Friday, the whole Church venerates the Cross by kissing it: it is not the wood she worships, but the Savior who died on it — “through the images we kiss, it is Christ whom we worship”^[27].

“What about statues that weep or work miracles?”

Here the Church is extremely cautious: it never obliges belief in such phenomena and subjects them to long investigations. But God truly gives such signs. At Akita (Japan), the statue of the Virgin wept on 101 occasions between 1975 and 1981; at the close of the diocesan inquiry, Bishop John Shojiro Ito, bishop of Niigata, recognized their supernatural character by a pastoral letter of 22 April 1984, authorizing veneration in his diocese pending the definitive judgment of the Holy See^[28]. Here as always, power never comes from the object but from God alone, who uses a sensible sign to touch hearts. When popular devotion slides toward superstition — attributing a power to the object itself — the Church corrects it, as Hezekiah broke the bronze serpent turned idol. And the Council of Trent requires that no new miracle be recognized without the examination and approval of the bishop^[29]. The rule remains: the image is a path toward God, never a destination.

Catholics use images and statues because the Bible never forbade representation, only the idol — and God himself had cherubim of gold sculpted and a bronze serpent raised for his own worship. Above all they do so because God became man: by becoming visible, Christ made it legitimate, and even fitting, to depict him. Refusing every image would amount to downplaying the Incarnation.

These images are neither idols nor decorations: they teach the faith, recall salvation, lift the gaze toward God, and help the body pray. The believer never worships them — he honors them, and that honor rises entirely to God and his saints. “The honor paid to an image passes to its prototype”: this formula of Saint Basil, taken up by Nicaea II more than twelve centuries ago, says it all. The statue is only a window — and no one has ever worshiped a window for the light it lets through.
