Catholic peace group to honor victims of nuclear weapons with lantern ceremonies
Pax Christi International is partnering with the Hiroshima Coventry Club to launch the “Lanterns for Peace: from Hiroshima to the World” campaign, encouraging communities globally to hold lantern floating ceremonies. The ceremonies will commemorate the 1945 atomic bombings of Hiroshima (Aug. 6) and Nagasaki (Aug. 9), using lanterns as symbols of remembrance, hope, and a call for nuclear disarmament. Local groups are invited to adapt the event to their context, with guidelines provided in a booklet that includes instructions on building lanterns, moments of silence, and survivor testimonies. The initiative seeks to foster collective conscience and promote peace amid growing nuclear threats worldwide. The campaign underscores that the lanterns represent remembrance of lost lives, hope for reconciliation, and commitment to abolishing nuclear weapons.

The Catholic peace movement Pax Christi International has launched the “Lanterns for Peace: from Hiroshima to the World” campaign, inviting communities worldwide to hold lantern‑floating ceremonies that commemorate the victims of the atomic bombings of Hiroshima and Nagasaki and call for nuclear disarmament. 1
Pax Christi International is partnering with the Hiroshima Coventry Club (Touro Project) to coordinate the lantern‑floating events during the summer of 2026. The campaign draws inspiration from the annual lantern ceremonies held in Hiroshima and aims to spread the practice to other cities and towns. 1
The lanterns serve as symbols of remembrance for those who perished, hope for reconciliation and peace, and a collective commitment to abolish nuclear weapons. Each ceremony includes the floating of lanterns (where safe and permitted), a moment of silence or prayer, and the reading of survivors’ testimonies. A booklet released by the group provides instructions for building lanterns and adapting the ceremony to local contexts. 1
Communities worldwide are encouraged to organize their own events while maintaining shared symbols, messages, and commitments outlined in the campaign’s booklet. The initiative marks the anniversaries of the Hiroshima bombing on August 6 and the Nagasaki bombing on August 9, 1945, fostering a unified yet locally tailored observance. 1
The campaign emerges amid renewed concerns about nuclear threats, positioning the lantern ceremonies as both a moment of mourning and a “genuine call to conscience” for peace and nuclear disarmament. By linking the memory of past devastation with contemporary advocacy, the effort seeks to keep the moral imperative for a nuclear‑free world alive across diverse cultural settings. 1*
How does the Catholic Church’s doctrine of peace inform nuclear disarmament?
The Catholic Church teaches that peace is not merely the absence of war; it is a positive, ordered reality rooted in justice and charity. From that doctrine, the Church draws concrete implications for nuclear disarmament: nuclear weapons cannot be a legitimate instrument of peace, and the pursuit of peace therefore calls for verified, patient, multilateral steps toward eliminating nuclear arms and reducing their operational risks.
Catholic teaching defines peace in a deep way: it is “the tranquility of order,” and it is “the work of justice and the effect of charity.” This matters for nuclear policy because a “balance of terror” is not the tranquility of order; it is a stability constructed on fear, mistrust, and the threat of catastrophic destruction.
The Church links peace to safeguarding “the goods of persons,” “free communication,” and “the assiduous practice of fraternity.” Peace, therefore, cannot be reduced to deterrence arrangements that treat human life as an acceptable casualty for “security.”
A further principle is that peace is indivisible: “the security and peace of some” cannot be disconnected from “the collective security and peace of others.” Nuclear weapons, by their nature, contradict this universality because their use or even accident would reach beyond any “protected” group.
The Church’s reasoning is not only about outcomes; it is moral. The teaching reiterated by Pope Francis states:
“the use of nuclear weapons, as well as their mere possession, is immoral.”
This is a decisive pivot: if possession itself is morally problematic, then “deterrence” cannot be treated as a morally sufficient substitute for disarmament.
The Holy See teaches that trying to defend stability through terror “inevitably ends up poisoning relationships between peoples and obstructing any possible form of real dialogue.” The doctrine of peace therefore supplies a critique internal to the Church’s own concept of peace: peace is dialogue-oriented and fraternity-building, not fear-imposed.
The Church highlights both the catastrophic humanitarian and environmental consequences of any use and the precariousness from mere maintenance (accidents, involuntary or otherwise). Peace doctrine is concerned with safeguarding persons and protecting the common good; these risks show nuclear weapons are structurally incompatible with that demand.
U.S. Catholic teaching summarizes the Church’s longstanding position: “The United States and other nuclear powers must move away from reliance on nuclear weapons for security.” The Church further urges that “nuclear deterrence be replaced with concrete measures of disarmament based on dialogue and multilateral negotiations.”
This is direct application of the Church’s peace framework: peace is built through justice, charity, fraternity, and patient diplomacy, not force alone.
The Church does not treat arms control as merely technical bureaucracy. It urges viewing arms control “not as ends in themselves but as steps along the way to achieving a mutual, verifiable global ban on nuclear weapons.”
That aligns with a peace doctrine that rejects fear-based “order” and instead aims at genuine, trustable order founded on justice and mutual security.
Peace is not only a moral aspiration; it must be practicable in ways that protect persons. The Church therefore emphasizes “mutual, verifiable” disarmament and the reduction of acute risks—e.g., taking weapons off “launch on warning” status to prevent a catastrophic accident.
The emphasis on verification and inspections appears in the Church-supported discussion of New START: verification and transparency are presented as foundations that make even modest reductions possible as part of a broader disarmament path.
From the Church’s policy presentation, nuclear disarmament informed by the doctrine of peace includes:
Catholic doctrine allows defense of the innocent and the common good, but it insists that authority must ensure security “by morally acceptable means.”
Accordingly, the Church’s approach is not pacifism in the sense of ignoring threats; it is a judgment that nuclear weapons are not a morally acceptable means of securing peace. The Church even acknowledges the claim that minimal nuclear capability might deter—but then rejects deterrence as the final answer, urging replacement by concrete disarmament measures grounded in dialogue and multilateral negotiations.
Pope Leo XIV’s peace teaching frames the alternative sharply: fear-based “force and deterrence” cannot build true peace. Instead, true peace requires trust—linking peace to a disarming peace and the renewal of heart and mind toward disarmament.
From this standpoint, nuclear disarmament is not only a strategic policy preference; it is a moral and civilizational response to the Church’s own definition of peace.
In sum: Catholic doctrine of peace—peace as an ordered gift of justice and charity, universal in scope, built through dialogue rather than fear—directly informs nuclear disarmament by teaching that nuclear weapons (including their possession) are immoral and that genuine peace requires verified, multilateral, gradual (but real) steps toward elimination, paired with concrete measures that reduce catastrophe risk and rebuild trust.
