How Christianity Shaped Art

And how to paint the infinite

Early Christian artists faced an impossible challenge: how do you depict a God who exists beyond the limits of space, time, and material representation?

What does it mean to paint the infinite? To give form to the formless?

It was a task that required not only technical skill, but a theologically robust conceptual framework that invited contemplation while still preserving the mystery of faith.

Compared to other religious traditions, Christianity’s approach was unique. In Islamic culture, for example, depictions of divine figures are forbidden, and beauty is expressed through pattern, calligraphy, and architecture. The Jewish tradition maintained similar caution in its development, avoiding imagery that might blur the line between reverence and idolatry.

Early Christians were well aware of the risks involved in portraying divinity, and were hesitant to embrace religious imagery from the outset. But over time, the theological foundation of the faith invited a deeper exploration of what painting and sculpture could do.

In the process, Christianity transformed the very meaning of art itself — and set the path for all art (secular and religious) to this day…

The Art of the Incarnation

In the early centuries of the Church, depictions of Jesus were rare and often symbolic. Even the cross itself wasn’t commonly portrayed in the first few generations after Christ’s death, as his early followers were wary of visual representations that might be confused with the idols of pagan Rome.

Instead, they relied on discreet signs and images that carried meaning through suggestion — the fish, the vine, the shepherd, and the anchor all hinted at the Gospel, without revealing too much.

Gradually, this caution gave way to a new question. If Jesus was truly the Son of God, and if he truly took on human nature, then wasn’t it appropriate to portray him?

The idea of the Incarnation became central to this shift. According to the Gospel of John, “the Word became flesh and dwelt among us.” For early believers, this meant that God had literally — not metaphorically — entered into the physical world of dirt, food, and flesh. In other words, the invisible had become visible.

This concept opened the door for Christian artists to engage with the depiction of God the Son, the deity who had walked among men. But still, the challenge remained — how could images made by human hands express both the humanity and the divinity of Christ?

To answer this, artists first turned to symbolic forms. The mandorla, an almond-shaped frame, placed Christ at the intersection of heaven and earth.

Halos surrounded his head with golden light. Every detail from his hand gestures to his clothes was carefully chosen, and each aspect of his depiction was intended to convey theological truths (a practice maintained to this day in traditional iconography).

This intentionality and reverence extended to other saintly figures as well — the Virgin Mary, for example, was depicted alongside lilies or in enclosed gardens to reflect her purity and her role in salvation history.

But while symbolism was useful, it only carried artists so far.

Because while it’s one thing to depict God-become-man, it’s another thing to depict an eternal reality — what the Gloria Patri says was “in the beginning, is now, and ever shall be: world without end…”

Layering Time, Depicting Eternity

As Christian theology developed, artists expanded their vision beyond simply portraying divine figures to suggesting something about the nature of time itself.

The Christian understanding of history is not linear in the modern sense. Events from different centuries are linked by a common spiritual thread. Creation, the Incarnation, and the Passion are not just isolated moments in history, but spiritual realities being perpetually played out — God is always creating, always walking among us, and always being crucified.

Artists began to reflect this in their work, pairing figures from vastly different eras together in the same image. A painting of the Nativity, for example, might include saints who lived centuries later, whereas a scene from Christ’s Passion might be set against the architectural backdrop of medieval Europe.

The Sienese altarpiece known as the Maestà is one such example. In it, the artist Duccio di Buoninsegna depicts Old Testament prophets, angels, apostles, and early medieval saints together with the Virgin Mary and Christ. Though it might appear incongruous to many viewers today, it is in fact a deliberate choice to express the timeless unity of salvation history.

This kind of art encouraged those who engaged with it to step outside the ordinary flow of time. It offered a glimpse into sacred history as a living reality, and inspired people to consider how their life in the present would echo in eternity.

But all of this combined to prepare the viewer for a more ambitious possibility — that art might not only depict eternal truths, but direct the soul toward them. And this idea has shaped almost all art, both secular and religious, ever since.

Christian art was never meant to merely impress viewers, but to lead them beyond the frame.

It was meant to be looked through, not at…
