Catholic teaching connects artistic witness, peace, and nuclear disarmament through a common conviction: peace begins when people learn to see one another truthfully—as members of one human family, not as enemies to be controlled by fear. Art can help make suffering visible, give voice to those whose experience is ignored, and awaken moral imagination. It cannot replace political action or disarmament agreements, but it can help form the conscience and mutual trust without which lasting peace is difficult to build.

Art as a form of witness

The Church does not treat art as merely decorative or as a tool for making religious ideas attractive. Pope Leo XIV describes authentic art as a way of attending to the questions and wounds of human life, and of making what people long for or suffer “audible, visible and shareable.” In his account, art cultivates listening: it can disclose aspirations for beauty, justice, and peace that may otherwise be drowned out by noise or reduced to slogans. 1

The “restlessness” here is the human search for truth and meaning. Art’s witness is therefore not limited to depicting events. It can invite people to look again, to notice persons and consequences that political or military language can obscure, and to resist a culture that makes human suffering easy to ignore. Leo also says artists are called not only to create beauty but to reveal truth and goodness within history, give voice to the voiceless, and transform pain into hope. 2

That is especially pertinent to nuclear weapons. Artistic work can preserve the memory of victims and survivors, communicate the lasting human and environmental consequences of nuclear use and testing, and help later generations confront what such weapons mean in human terms. The Holy See has recognized the witness of the Hibakusha—survivors of the atomic bombings and nuclear testing—as keeping alive collective memory of the horror and suffering involved. 3 Such witness is not simply an argument about weapons policy: it asks viewers and listeners to attend to lives affected, and to the responsibilities owed to victims and future generations.

Peace is more than the absence of war

Catholic teaching does not identify peace with a calm maintained by fear, military balance, or the threat of mutual destruction. Pope Francis argues that peace and international stability cannot be built on the prospect of annihilation; they require solidarity, cooperation, and shared responsibility among peoples. He also stresses that nuclear arms divert resources from human development and damage the natural environment. 4

The Holy See’s statements likewise connect peace with mutual trust, dialogue, and fraternity. Archbishop Gabriele Caccia’s 2022 address recalled St John XXIII’s insistence that lasting peace rests not on equal armaments but on trust, and called for an “integral disarmament” that includes a change of heart as well as agreements between states. 5 “Integral” here means that disarmament is not only a technical process—reducing weapons or verifying compliance—but also an ethical effort to replace fear and mistrust with habits and institutions that support cooperation.

This is one way artistic witness can contribute: art can challenge the imagination that makes an enemy seem less than human, expose the human costs hidden behind abstract language, and invite attention to shared grief and vulnerability. That is a contribution to the moral conditions of peace, not a substitute for diplomacy, verification, or political decision-making.

The Church’s call for nuclear disarmament

The Church’s opposition to the arms race and its pursuit of disarmament have been consistent, though the language and practical emphasis have developed. In 1982, St John Paul II said the Church deplored the arms race and called for mutual, progressive, and verifiable reductions in armaments, while also insisting that every nation’s independence, freedom, and legitimate security be respected. He envisioned security arrangements that would make vast arsenals of fear unnecessary. 6 This combines a clear direction—away from armament and toward disarmament—with attention to the genuine security concerns of peoples.

More recent Holy See statements express the moral urgency of eliminating nuclear weapons in especially direct terms. In 2019, Pope Francis argued that possessing nuclear weapons does not provide a sound basis for security and called for continued work supporting international instruments for disarmament and non-proliferation, including the Treaty on the Prohibition of Nuclear Weapons. 4 In 2023, the Holy See’s representative at the United Nations said that rejecting nuclear deterrence entails eliminating nuclear weapons and called on states to join the prohibition treaty. The address also emphasized dialogue, verification, assistance to people harmed by nuclear weapons, and restoration of contaminated environments. 7

The underlying moral concern is not only that nuclear weapons could be used, but that a security system based on threatening mass destruction places human life and the future of communities at grave risk. The Holy See has explicitly condemned threats to use nuclear weapons as immoral and dangerous. 8 Its statements also argue that a treaty alone cannot accomplish the deeper task: disarmament needs an ethic that forms people and nations to pursue security through fraternity and solidarity rather than an unstable balance of terror. 3

Bringing artistic witness and disarmament together

The connection is therefore practical as well as symbolic. Artistic witness can keep the human reality of nuclear weapons present in public consciousness, where discussion might otherwise remain confined to strategy, deterrence, and national interest. It can honour victims, preserve testimony, and help audiences recognize the responsibilities involved in preventing further harm. The Church’s emphasis on listening and on giving voice to the voiceless provides a basis for understanding such work as a service to human dignity. 1 3

But Catholic teaching also cautions against treating art as a complete solution. Art may awaken attention, memory, and compassion; disarmament still requires responsible political action, dialogue, agreements, and credible verification. St John Paul II urged serious proposals to be considered prudently and objectively, without inflammatory rhetoric that aggravates an already dangerous situation. 9 Artistic witness is most faithful to peace when it tells the truth without dehumanizing, bears witness without exploiting suffering, and moves people toward responsibility rather than despair or hatred.

Taken together, these teachings suggest that artistic witness is one way of serving peace: it helps people see what fear and abstraction can conceal. Nuclear disarmament is the corresponding public and political task—building security through trust, cooperation, and protection of human life rather than through the threat of mutual annihilation.
