However, the Church also teaches that in extreme circumstances – when diplomacy and all other peaceful means have been exhausted – war is not only necessary, but a moral obligation.
A thread on Just War Theory.
In his Summa Theologiae, St Thomas Aquinas presents a compelling argument concerning the three essential conditions that must be fulfilled in order for a war to be considered just.
These conditions form the foundation of the principles of jus ad bellum (justice to war).
The first condition St Thomas Aquinas stipulates is that war must be declared by a legitimate authority.
He explains that "the natural order conducive to peace among mortals demands that the power to declare and counsel war should be in the hands of those who hold the supreme authority".
This requirement ensures that private individuals or groups cannot initiate wars based on personal grievances, but rather that the decision to go to war rests with those entrusted with the care of the citizens and the common good.
Secondly, St Thomas Aquinas insists that a war can only be declared for a just cause.
He states, "a just cause is required, namely that those who are attacked, should be attacked because they deserve it on account of some fault".
This condition emphasises that war should not be waged for immoral or arbitrary reasons, but must be in response to a significant evil or injustice.
St Thomas Aquinas elaborates on the importance of a just cause, stating "a just war is wont to be described as one that avenges wrongs, when a nation or state has to be punished, for refusing to make amends for the wrongs inflicted by its subjects, or to restore what it has seized unjustly".
As a result, war is an extreme but necessary means to restore order and justice.
The third and final condition St Thomas Aquinas presents for a just war is right intention.
He asserts that combatants must always "intend the advancement of good, or the avoidance of evil" even during battle.
This condition excludes wars waged out of vengeance, personal hatred, the desire for financial gain, or other immoral motives as these render the war unjust.
St Thomas Aquinas emphasises the fact that "true religion looks upon as peaceful those wars that are waged not for motives of aggrandisement, or cruelty, but with the object of securing peace, of punishing evil-doers, and of uplifting the good".
This guides the principles of jus in bellum (justice in war), which stipulates that combatants are not permitted to attack civilians, plunder innocent targets, or mistreat prisoners of war.
It is important to note that St Thomas Aquinas' Just War Theory also incorporates elements of proportionality and emphasises that war must be a last resort, though these are not explicitly stated as separate conditions.
He suggests that one cannot wage war over slight causes and that there must be a reasonable hope of success on behalf of those fighting, and that the war can't generate greater injustices than those of the current state.
These considerations further refine the application of Just War Theory, ensuring that the decision to go to war is made with careful deliberation and with due consideration of its consequences.
St Thomas Aquinas' Just War Theory remains relevant in the modern world as a moral framework for evaluating the justification and conduct of warfare, providing principles such as just cause, right intention, and legitimate authority that can be applied to contemporary conflicts.
Ultimately, war is necessary in extreme circumstances as a means of restoring order, as the Philosopher states, "we make war that we may live in peace".

In an age marked by growing spiritual uncertainty and social fragmentation, the Roman concept of religio offers a powerful lens through which we can examine the cause of our societal malaise.
A mega-thread.
To the Romans, religio was far more than a matter of private belief or personal devotion, it was a binding force that united individuals within a framework of collective ritual, tradition, and civic responsibility – one of the integral pillars of the Mos Maiorum.
The Roman experience reveals how the dissolution of a common religious fabric can precipitate moral decline, social fragmentation, and, ultimately, the weakening of civilisation itself.
However, the Church also teaches that in extreme circumstances – when diplomacy and all other peaceful means have been exhausted – war is not only necessary, but a moral obligation.

The Seven Deadly Sins are vices that are the most destructive to one's spiritual growth.
Discover what these seven deadly sins are, and how to conquer them.
A thread.
Pride is considered the most dangerous of the Seven Deadly Sins.
It is an unwillingness to live in accordance with the truth, an inordinate desire for excellence or glory beyond one's state in life, and judging oneself greater than one is.
Greed (or avarice) is an inordinate desire for material possessions, wealth, or power. It is characterised by an insatiable desire beyond what is necessary in accordance with one's state in life, and often at the expense of the common good.
Apart from their military training, the real secret behind the Spartan hoplite was Spartan women.
Discover the role of women in shaping one of the most legendary societies in Western history, and why this still matters today.
Spartan women were fundamentally important in maintaining the Spartan city-state's military ethos.
Unlike women in neighbouring city-states, Spartan women enjoyed a level of freedom and respect that was almost unparalleled in the ancient world.
Spartan women were educated and trained to be almost as formidable as their men, which reinforced the city-state's martial ethos.
According to Xenophon, Spartan girls were expected to "exercise no less than the male" as "healthier children will be born if both parents are strong".
Have you every wondered why so many elements of the Catholic liturgy are missing from the earliest centuries of Christianity?
The answer lies in the dramatic history and hidden struggles of the early Church.
A mini-thread.
During the first centuries of Christianity, the Apostles and their followers were forcibly excluded from their synagogues and faced systematic persecution by the Roman Empire.
This made any public display of faith extremely dangerous, often leading to mass public executions.
As a result, Christians were forced to worship in extreme secrecy – often in catacombs or private homes.
They had neither the freedom nor the resources to practice and develop elaborate liturgical ceremonies, vestments, or public rituals.
But it is not a war for wealth or resources – it is a war for your immortal soul.
Discover the origins of evil, the principles of demonology, and the nature of spiritual warfare.
A mega-thread.
Demons are fallen angels with angelic powers.
Like human beings, demons were created with free will, and their fall during the first instances of creation was a result of their individual choice to either serve or rebel against God.
Theologians and exorcists suggest that each demon fell in relation to a particular aspect of salvation history that was revealed to them in these first instances of creation.
Some fell because they rejected God's mercy, some because they rejected the incarnation, and the aspect of their particular rebellion or non serviam animates the vice or domain for which they are responsible.
