Pope Leo XIV praised the forthcoming U.S.–Iran Memorandum of Understanding, urging that dialogue replace conflict and hoping the pact will become a genuine end to hostilities, while also calling for broader peace efforts in the Middle East and an end to the war in Ukraine. His remarks, delivered to journalists and during a General Audience, linked the agreement to the Church’s call for mutual trust, security, and respect for human dignity, and he reiterated the need for continued prayer and negotiation on other global crises. 1 2 3
Pope Leo XIV said “thank God, there is at least this Memorandum that they will officially sign on Friday,” emphasizing that “it is always better to do so through dialogue, through negotiation, rather than returning to war.” He expressed hope that the agreement could be “truly a solution to the war” and that it would help eliminate nuclear weapons and address economic and social problems created by the conflict. 1
In a General Audience the Pope added that he “welcome[s] with satisfaction the reaching of an agreement … as an encouraging result of patient work of dialogue and negotiation,” and thanked third‑party nations that facilitated the talks. He said the pact could “strengthen mutual trust, security and stability in the Middle East, promoting paths of dialogue and cooperation among peoples.” 2
While praising the memorandum, the Pope noted that “there will still be several points to be established,” urging both sides to continue negotiations to resolve outstanding matters. He called for the agreement to be a lasting peace that moves beyond mere signatures. 1
During the same audience, Pope Leo XIV turned to the war in Ukraine, lamenting the growing civilian toll and destruction of cultural heritage. He invited everyone to pray for an end to that conflict, asking the Lord to “open pathways to dialogue, extinguish hatred, and make a just and lasting peace possible.” 2 3
In a separate press briefing, the Pope also spoke about his recent trip to Spain, migration concerns, and the Society of Saint Pius X’s planned episcopal consecrations, but these remarks were distinct from his comments on the U.S.–Iran agreement. 1*
How does the Catholic Church interpret diplomatic agreements as instruments of peace?
The Catholic Church treats diplomatic agreements as genuine instruments of peace—not as mere political tactics, but as moral and juridical means that help build a stable and just order, reduce the suffering caused by conflict, and keep open the “room for dialogue” that prevents disputes from escalating into violence.
Catholic social teaching and the Catechism connect peace with justice, respect for human dignity, and the “tranquillity of order.” Peace is therefore not simply “no fighting,” but requires safeguarding persons and fostering fraternity and rightful social arrangements.
From this perspective, diplomatic agreements matter because they aim to shape a just order that provides security for society through morally acceptable means. The common good requires peace as “the stability and security of a just order,” which authority must protect.
A key Church statement on the Church’s diplomatic activity explains that the good of peoples and communities is served by a structured dialogue between the Church and civil authorities, and that this dialogue “finds expression in the stipulation of mutual agreements.”
Those agreements are described as serving specific peace-oriented aims:
In the same line, Pope Paul VI emphasizes that diplomatic activity is patiently used to contain tensions and maintain room for dialogue, so that rational solutions can be found rather than tensions degenerating into open warfare.
Catholic teaching also presents dialogue and negotiation as the “best channels” for solving contentions between nations and peoples.
This matters because the Church sees conflict often arising from deeper moral failures—such as partial and distorted views of reality, unjust blame, and the atrophy of solidarity. Diplomacy and agreements are therefore not only procedural; they are meant to counter these dynamics by enabling negotiation and restoring a realistic, truthful understanding of the common human good.
Pope John Paul II calls diplomacy (and the legal ties formed through common, loyal agreements) an “art of peace,” aimed at preserving or restoring peace and promoting cooperation through peaceful legal relationships.
In Catholic thought, an agreement that is not honored undermines peace. The Church teaches that many states have subscribed to international agreements meant to make military activity less inhuman—especially conventions concerning the handling of wounded or captured soldiers and similar instruments—and that such agreements must be honoured.
Moreover, Pope Francis stresses that the Church supports greater international effort to defend and implement humanitarian law, explicitly citing the Council’s teaching that these agreements “must be honoured” and improved so as to curb war’s savagery more effectively.
So, for the Church, respecting diplomatic and humanitarian agreements is not optional—it is part of the moral architecture of peace because it protects the dignity and lives of persons even amid conflict.
The Church insists that agreements are peace instruments only within a larger moral framework.
Pope Leo XIV explains that building peaceful relationships requires:
He also lists justice and truth as essential: peaceful relationships cannot be built “apart from truth,” and working for peace requires acting justly.
This means diplomatic agreements are not merely technical documents; they must rest on truthful negotiation and justice, or they risk becoming instruments that stabilize injustice rather than peace.
Pope Leo XIV also links peace-building to halting the production of “instruments of destruction and death,” reflecting the conviction that “no peace is possible without true disarmament.”
Accordingly, the Church’s vision includes both:
The Catholic Church is realistic: it does not teach that peaceful agreements alone can always prevent immediate danger. The Catechism states that all citizens and governments are obliged to work for avoiding war, but also that governments cannot be denied the right of lawful self-defense when the danger of war persists and there is no international authority with sufficient competence and power—once all peace efforts have failed.
This highlights a balancing point in Catholic interpretation:
Catholic teaching interprets diplomatic agreements as peace instruments because they:
