Cardinals back Pope’s “outdated” verdict on just war
The terminology is shifting toward proportionate defense, as the means and scope of war is so vastly different than in the times of St. Augustine.

The cardinals have publicly supported Pope Leo XIV’s recent judgment on the doctrine of just war, a stance that some observers have described as “outdated.” 1
Pope Leo XIV issued a verdict concerning the Catholic teaching on just war, reaffirming or redefining its criteria. The content of the verdict is characterized by critics as reflecting an older perspective. 1
A group of cardinals issued statements backing the Pope’s position on the just war issue, indicating alignment with the Holy See’s interpretation despite the criticism of the verdict’s antiquated nature. 1*
Do Catholic doctrines still justify war under contemporary circumstances?
Catholic doctrine does not treat war as an automatic or easily “justifiable” option in contemporary circumstances. It teaches that peace is a serious obligation and that armed force is only morally permissible under very strict conditions—conditions that must be judged prudently by those responsible for the common good, and that become harder to satisfy precisely because modern war can cause catastrophic evils.
The Church teaches that because of the evils and injustices war brings, “we must do everything reasonably possible to avoid it,” and she prays for deliverance from war.
This “avoid war” orientation is not merely sentimental; it is built into the moral logic of Christian charity. Pope Leo XIV similarly frames peace as something that must be pursued actively, stating that it is possible to “build peace” and stressing that prayer for peace is not an escape from responsibility but a transformative response.
Catholic teaching holds that even though war is gravely harmful, it is still possible that governments may have a right to lawful self-defense—but only after peace efforts fail and only where certain conditions apply.
The Catechism summarizes the traditional “just war” doctrine and emphasizes the rigorous conditions of moral legitimacy for the use of military force:
It also highlights that “the power of modern means of destruction weighs very heavily” in judging whether these conditions can truly be met.
Finally, the Catechism is explicit about responsibility for judgment: the evaluation belongs to the prudential judgment of those who have responsibility for the common good.
It means contemporary conditions do not remove Catholic doctrine; they often make the doctrine’s conditions harder to satisfy:
Even where defense might be contemplated, the Church warns against an overly expansive reading of the right to use force. Pope Leo XIV, quoting and drawing on Fratelli Tutti, notes that in recent decades wars have often been “ostensibly ‘justified’” and that while the Catechism acknowledges legitimate defense under “rigorous conditions,” it is easy to fall into an overly broad interpretation—including wrongly justifying even “preventive” attacks or wars whose harms cannot be avoided.
So Catholic doctrine can justify some uses of force, but it does not permit treating “just war” criteria as a rhetorical label that can cover almost anything.
Catholic teaching insists that once war begins, morality does not disappear. The Catechism states: “The mere fact that war has regrettably broken out does not mean that everything becomes licit between the warring parties.”
It also teaches that the Church urges action so that divine goodness frees humanity from “the ancient bondage of war,” reinforcing that violence is never morally weightless.
