Immanuel Kant, Critique of Practical Reason (1788)
INTRODUCTION

Military work is, in essence, the use of force; or more explicitly, the capacity to kill and destroy.1 This is the singularity of military work, making it unique and demanding for military personnel who must comply with extremely strict rules of conduct and decision-making. This essay looks at the latter i.e. decision making, which essentially refers to soldiers’ inner lives, beliefs, and values. The Roman Catholic Church has developed ethics of war, which are characterised by a strong focus on each soldier’s capacity for judgement and on defining soldiers as peacebuilders. 2 Considering soldiers as enlightened men building peace during their military operations is, therefore, the proposal of the Church.3 This goes much beyond
peacekeeping, which is the maintenance of an acceptable level of security and an avoidance of escalation. The Church believes instead that soldiers have the power to replace the bonds of war with the bonds of charity, thereby being peacebuilders even in times of war.

The Kant quote in the epigraph captures the persistent belief that men can reconcile the complexities of life on earth with their ethical ideals. This is true even for soldiers, who can approach their martial functions by combining their military ethics and the ethics of the Church. The Church has elaborated its ethics of war based on the Gospels and the lessons of Jesus of Nazareth. Nevertheless, these ethics are not directed to Christians only but instead to all people of good will to whom the Christian vision can resonate — “Glory to God in the highest; and on earth peace to men of good will (Luke 2:14 NIV).” In that perspective, contemplating Catholic ethics should not be contradictory with secularity—most States are
now secular, often strictly separated from the Church, and so are their armed forces.

There is no single text or compendium containing all elements of the Church’s vision on warfare, which covers a wide range of practical topics such as decision-making, individual responsibility, conduct, right of self-defence, as well as larger ethical questions about the place of conflict within society. The Church’s vision on warfare is instead disseminated across several documents, notably the Catechism of the Catholic Church, the Compendium of the Social Doctrine of the Church, and several encyclical letters. The key ones being Pacem in Terris, Gaudium et Spes, and Fratelli Tutti.4 In addition, this is supplemented by Papal sermons, publications by conferences of bishops, and significant works by academic theologians. This article proposes to summarise and explain the contemporary vision of the Church, displaying its resonance with current ethical frameworks and practices within the European Union (EU) and the North Atlantic Treaty Organization (NATO). Western and EU countries are already much aligned with the commands of the Church, due to their Christian roots. Even though there is a ‘by-default’ alignment, the vision of the Church still departs in many aspects. Bluntly summarised, the Church thinks about war as part of its wider project: to reform humanity and create a new society based on love and charity that pursues the common good.5 No Western or EU nation has committed to such an absolute project, and secular nations have been instead directed to the cohesion and temporal welfare of their citizens, emphasising the role of individual rights in line with liberalism.

The first element to note addresses key concepts that underlie the commands and rules for warfare. Much of the difference between the ethics of the Church and armies originate here. The Church can be seen as idealistic and absolutist (ban of war, peaceful resolution of disputes) versus States and their armed forces
that grapple with violence, aggressions, and provocations. The second element considers the practical commands for combatants, who are ultimately called by the Church to work on their inner self to profoundly anchor values including, love and charity. In short, combatants, whatever their rank and responsibilities, are asked to be builders of peace even in wartime through their actions and convictions. Building pax in bello 6 is necessary for a stable and durable pax post bellum, thereby gradually replacing the bonds of war with the bonds of charity, with the hope of reaching perpetual peace.

VISION, COMMANDS AND EXIGENCIES OF THE CHURCH TO BUILD A PEACEFUL SOCIETY

Conceptions of life, society, men and peace have a somewhat different meaning in the view of the Church in comparison to the most commonly accepted definitions. These fundamental deviations lead the Church to enact more radical and difficult-to-implement commands. One of the purposes of the Church is to push humans to change,7 and this includes battling against some of the most profoundly anchored features of human nature and instinct (such as violence and hate), in order to become closer to God, i.e. perfection. The pursuit of saintliness, versus the pursuit of happiness often set as the objective in secular nations,8 is therefore at the core of Christian life, and demands constant radical efforts over oneself.
Consequently, the Church does not intend to be pragmatic and accommodate its commands. This however does not necessarily mean that the Church is completely disconnected from reality and ignores it – on the contrary, the Church as an institution accompanies its members drawn into matters of war e.g. chaplains in the armed forces.9

Ethics of war are built on the balance of the capacity to kill versus the risk of being killed.10 The use of force is the monopoly of the State and soldiers have the exceptional right to kill during conflicts or under specific mandates. The use of force, together with conduct at war, are strictly framed by law (law of armed
conflicts, international humanitarian law, national laws), rules (rules of engagement), and customs. In essence, soldiers are authorised to kill, injure and destroy designated military targets. Thus the force is always constrained and limited to military necessity. Hence, the prohibition of killing is the normal rule (under civilian criminal law), and the right to kill is highly constrained and exceptionally granted to soldiers by the State. While States have clearly defined legal frameworks, rules, procedures and ethics for the use of force, the position of the Church is instead radical (no use of violence) and somewhat contradictory (still including indications for combatants when fighting).

The radicalism of the Church lies in the absolute biblical prohibition of killing — “[t]hou shalt not murder (Exodus 20:13 NIV),” and in the effective Papal ban of war enshrined by Pope Francis. He practically ends the centennial just war theory,11 which still applies theoretically, but simply no wars can now meet its criteria. Just war theory was, in short, a long-standing development that framed war as an exception,
always wrong, but capable of being conducted with tragic integrity.12 This tradition set out criteria and conditions allowing wars and limiting the use of force.13 Although just war theory is now in the process of being decommissioned, it has durably influenced the Western conceptions on war and the use of force, and most of its principles are replicated in existing laws, rules and customs (e.g., necessity to justify war,
necessity to find a peaceful resolution before entering into war). The prohibition of killing is corollary to the fundamental principle of the sanctity of life,14 that is to say, men cannot destroy life because it is a divine creation and project. Hence, the entire vision of the Church for society and men’s conduct is built on the protection and defence of life.

Alongside life, peace is fundamental in Christianity. It is an attribute of God—“the Prince of peace (Isaiah 9:5 NIV)”— and a legacy of Jesus of Nazareth—“[p]eace I leave with you, my peace I give to you (John 14:27 NIV).” This leads the Church to give an absolute definition of peace, which is “the fullness of life,”15 as well as the divine plan for humanity.16

Furthermore, peace denotes a state in which a society can live not only in moral and physical security but also in which it can develop strong and fair social bonds, i.e. “safeguarding the goods of persons, free communication among men, respect for the dignity of persons and peoples, and the assiduous practice of fraternity.”17 In the Christian perspective, society is the common place of living for human persons to contemplate the development of moral virtues—justice, equality, mutual respect, sincerity, honesty, fidelity”18 which differs from the liberal view where the society is an aggregate of individuals
linked by a social contract to pursue common well-being and interests.19 Put bluntly, the Church
(and Jesus of Nazareth in the first place) deliberately sets the bar higher so, rather than gathering humanity around some synchronised and negotiated interests, it asks humans to build a society articulated around the same profound understanding and practice of values and ideals. To do so, the Church urges for a change of perspective, which should ultimately lead to more peaceful and fairer societies, “we need to think of ourselves more and more as a single family dwelling in a common home.”20 This society as defined by the Church does not exist yet, but the Church asks to work for its
advent and this goes through the deep change of individual and collective mentalities and behaviours, i.e. “a new vision of the world and a new way of approaching others”.21 Whereas the Church, as an institution, has had essentially conservative and reactionary positions, the recent return, impelled by Pope Francis, to the core concepts and commands restores Christianity in its original revolutionary approach
(“the music of the Gospel”).22

“Christian peace”, seen by the Church as genuine or just peace,23 is more exacting than peace being the mere absence of war,24 and requires the full functioning and practice of institutions that guarantee liberty, democracy, and solidarity.25 “Peace is the work of justice and the effect of charity.”26 This absolute
definition of peace leads the Church to pay a lot of attention to post bellum considerations. It is to be understood within the wider Christian project to free humanity from the bonds of war (“the Divine Providence urgently demands of us that we free ourselves from the age-old slavery of war”),27 and to instead settle and stretch the bonds of charity.28 When war ends, the restoration of peace must be built to definitely end war and eradicate its roots. John Paul II declared that “[t]rue peace is never simply the
result of military victory, but rather implies both the removal of the causes of war and genuine reconciliation between peoples.”29 History tells that, indeed, inauthentic and incomplete peace
has failed to stop the spiral of competition and war.30 Therefore, armed forces have been involved in post bellum conflict contexts to ensure, among others, peace maintenance, the rebuilding of infrastructure, and settlement or restoration of democratic institutions.31

As noted earlier, the Church intends to reform people and urges them to overcome their most profound instincts. Therefore, the Church recognises that competition, violence, vengeance, and so war are inherent to human nature: “insofar as men are sinners, the threat of war hangs over them and will so continue
until Christ comes again.”32 Peace is eventually seen as the inherent objective of men—“[the] Creation, which is a reflection of the divine glory, aspires to peace.”33 which effectively suggests that the end of war is achievable here and now, i.e. without waiting for the supernatural advent of a hypothetical Second Coming.

In the Church’s view, the eradication of war can be attained by the practice of mercy, forgiveness, and reconciliation—which are pillar values taught by Jesus of Nazareth to “[l]ove your enemies and pray for those who persecute you (Matthew 5:44 NIV)”, “forgive us our trespasses as we forgive those who trespass against us […] but deliver us from evil (Matthew 6:9-13 NIV)”—as well as by the strength of faith
and prayer.34 Although the Magisterium does not mention it, the right to forget can be added
to the notion of forgiveness, as a way to end the spiral of violence.35 From that perspective, forgetfulness can be constructed as a form of enlightened remembering, i.e. “a deliberate choice to think differently about the past, an attempt to remember it in a more positive or constructive way.”36 Forgetfulness can also be temporary to allow peace, thereby restoring peace and stability immediately after conflict,
and waiting for Courts37 to conduct their investigations and to rule the cases.38

Hence, the combination of action (behaviour, undertakings, collective achievements) and prayer (practices, beliefs, convictions) is the motor of profound change—“the Church insistently urges everyone to prayer and to action so that the divine Goodness may free us from the ancient bondage of war.”39 Although the Church phrases this, understandably, in its technical language, this is still valid as a ‘secular
takeaway,’ meaning that pacifism and the resilience of societies to violence and war happen in actions and mindset—the latter being even more critical with the current development of strategies around cognitive warfare.40

The Church recognises that societies are entitled to “the right to peace,”41 which is going much
further than what secular nations commonly recognise (security, access to elementary care and services). Peacebuilding and peacekeeping are therefore two processes promoted by the Church as “[b]lessed are the peacemakers, for they will be called children of God (Matthew 5:9 NIV)”, which in that perspective supports military staff acting in the safeguarding of peace and the rescue of threatened populations.42

GUIDANCE AND INSTRUCTIONS FOR SOLDIERS TO ACT AS ENLIGHTENED PEACEKEEPERS

The responsibility for the ethical conduct of war lies with military staff. They train soldiers. They interpret doctrines, establish procedures, and maintain chains of command. They take the crucial decisions in the field, receiving and responding to information, define targets, select weapons, and ultimately fire the shots. They are the ones engaging with civilians. They are the ones responsible for prisoners. Even if the Church stands against war, there is still the recognition that the military is essential to protect a nation or a population, and to ensure peacekeeping. Consequently, the Church supports military staff and provides them with guidance to perform their tasks in peace, deterrence, competition, (d)escalation, and war.

Most importantly, the Church traditionally does not speak only to its believers, but instead to all people of good will. Founded on the message of Pentecost (Acts 2:1-11), the approach of the Church has been to talk to people in their own language, regardless of where they stand in their inner life (beliefs, faith, values) and in their life in action (work, social environment, family). This approach is exemplified in the slogan of St. Paul,43 who adapted his speech to various cultural and political audiences.44

Subsidiarity and Inner Leadership

In the Church’s view, military personnel have two key duties: the duty to serve their country and to act in favour of common good and peace45; and the duty of disobedience to unlawful, inhumane or immoral orders.46 For the latter, the Church targets the capacity of assessment of each personnel, thereby giving them an autonomy of decision as well as an individual responsibility, by being “fully responsible for the acts they commit in violation of the rights of individuals and peoples, or of the norms of international humanitarian law.”47 Military personnel are consequently seen before all as reasoning humans able to give meaning to their actions and to conduct moral or ethical assessment of their actions. This is close to the German vision, which considers soldiers above all as educated citizens (Staatsbürger in Uniform). In that perspective, German military staff are trained and educated to have the necessary knowledge and awareness to act at the best of their conscience, so called “inner leadership” (inner Führung).48 Delegating assessment to military staff refers also to the principle of subsidiarity, which finds its origins in church teaching, receiving its most influential modern treatment in Rerum Novarum.49 For now and in most Western armed forces, delegation to subordinates generally concerns a limited range of actions leaving little leeway for initiative.50 The Church and the Bundeswehr are here a step ahead by granting autonomy and anchoring a system of values in each personnel regardless of their rank (i.e. not only officers).51

Education and training of all soldiers on laws, morality, and ethics are critical and should be at a sufficient level to allow critical assessment. This is especially the case under stressful situations, during which reasoning is typically altered and instincts gain the upper hand because there is nonetheless “the permanent validity of the moral law during armed conflict.”52 Making the objectives of the military—“to defend good, truth and justice in the world”53 practical as well as instilling the reflex of critical assessment (on top of all fight reflexes) should therefore be the challenge of military academies and instructors.

Common good and peace

While serving the country is commonly agreed (often referred to as ensuring national security and sovereignty), common good and peace are rarely phrased in this way. Instead, “peacekeeping” is more often used. While the task of defining missions and their objectives sits at the political level (national governments, North Atlantic Council), the military is in charge of their implementation (strategies, operations, tactics).54 Therefore, common good and peace must be defined in concrete actions on the field by the military, considering inter alia the quality of communication with the population, attention
to the perception of legitimacy of their actions, and humane treatment of the population.55 More than restoring a certain level of security and stability, military personnel are considered by the Church as active builders of peace and good, so the seeds of peace must be sowed during their operations and during the war.

The Church defines the duty of protection (“the duty to protect and help innocent victims who are not able to defend themselves from acts of aggression”),56 with particular attention to civilians, refugees, and populations threatened of genocide.57 This duty can legitimise the use of force (“those […] [who] make use of [the] means of defence available to the weakest, bear witness to evangelical charity”)58, and must have priority over military objectives (“the good of the human person must take precedence over the interests of the parties to the conflict”)59 The duty of protection somewhat differs from the principles of humanity and discrimination, because it demands to actively engage the military in the protection of populations, and not only to avoid or bypass them during operations. Active protection of a population
also involves a complex conduct of operations, because civilians enjoy a protected status under the Geneva Conventions60 and other laws of war,61 and because the relationship with the local population can be difficult or even hostile, thereby adding social and psychological parameters.

The duty of protection is effectively a third-party support in self-defence. The right to self-defence
in treaties, laws, rules and customs is the only legitimate reason to enter into war.62 The Church
concurs with this approach (“the right and the duty to organize a defence even using the force of arms”),63 but warns against “an overly broad interpretation”.64 The Church states that all measures and efforts must be undertaken to avoid conflict,65 and self-defence should apply only “once all peace efforts have failed”.66

Furthermore, the Church lists conditions for self-defence, 67 which originate from just war theory and do not substantially differ from the commonly agreed approaches (although nations have different doctrines). In addition, the Church sees the right to self-defence, combined with the duty of protection, as the only legitimate reason for having armed forces (“the requirements of legitimate defence justify the existence in States of armed forces, the activity of which should be at the service of peace”).68 Similarly,
the right to self-defence is the only legitimate reason for building armament stocks, which should cover self-defence needs only and cannot exceed them.69 When it comes to armaments, the Magisterium prohibits possession and use of indiscriminate weapons,70 and more particularly chemical, biological, radiological and nuclear weapons,71 because they are “far beyond the bounds of legitimate defence”.72

Consequently, the Magisterium has strong moral reservations on deterrence, because it leads to infringements to the principle of sufficiency,73 and thereby increasing the likelihood of escalation of conflicts.74 The Church does not consider deterrence as a permanent and sustainable solution for ensuring peace, as the latter should instead emanate from the “mutual trust between nations and not be
imposed on them through a fear of the available weapons”.75

In summary, the Church’s commands and guidance are insightful, insofar as their focus is on intelligent and meaningful military decision-making and action to allow a swift return to peace. Put simply, based on the Church’s statements, the moral values of each military personnel should be sincerity, honesty, trustworthiness, respect, openness, fairness and charity.76 These values translate into concrete actions towards oneself, comrades, civilians, and even enemies: protect, communicate, listen, care and take care, educate and integrate. Points of attention are the defence of human dignity,77 and empathy 78“I have indeed seen the misery of my people in Egypt. I have heard them crying out […], and I am concerned about their suffering. So I have come down to rescue them […]” (Exodus 3:7-8 NIV). These values and behaviours should be developed and trained at the inception of a soldier’s career, during training, when stationed, and when on mission, so that they become anchored in mindset and habit. Quality of work is eventually the most critical issue, and this is achieved by continual training of body, mind, and professional tasks (drilling of procedures etc.). All this should lead to the maintenance of values on which fair societies are built, even in wartime, and thereby limiting the disruption of order caused by wars as
well as facilitating the restoration of peace.

CONCLUSION

Through its commands, the Church seeks to effectively translate the peace of God (Pax Dei) in actions and convictions for people so that they can frame and build peace (Pax Nostra) by extending and improving their own capacities and resources. By operating this translation, the Church delivers a universal message, that is to say, all people of good will (and not only believers) can follow the commands to build a steadfast peace. This also means that building peace is a mission for all humans. It is not a task narrowly charged to Christians, although believers may find in their faith and prayer strength and inspiration to conduct the mission of pacification.79

Thus, the contribution of the Church to the ethics of war is insightful, primarily because it addresses all personnel—regardless of their ranks—with a challenge to focus on inner leadership, i.e. the most profoundly anchored values and beliefs that guide actions. In addition, the Church believes in the capacity of humans to create, impact, and change themselves and their environment by means of individual and
collective actions. Therefore, although it is ancient, war is not an inevitability, and people are able to build peaceful societies. Believers may see in this the advent of the divine project for humanity as “[a] voice of one calling in the wilderness, ‘Prepare the way for the Lord, make straight paths for him’(Matthew 3:1-12
NIV)”, whereas people of good will may simply see the human aspiration to live in security and solidarity.

Ultimately, the Church calls on people to seek to surpass oneself, daring us to translate ideals into concrete actions, even if ideals – such as the end of wars – seem unachievable and fanciful. Therefore, military personnel must not renounce and cease to believe, but instead they must live and act in “a world where action is […] the sister of dreams.”80
