Just War and Just Peace

As the Ukraine War passes another milestone, can any war be considered just? Christine Schliesser explores Just War theory and a possible path to Just Peace.

Will Germany deliver Leopard 2 tanks to Ukraine? No? Yes? When? Media discussion of the war that the Russian Federation started against Ukraine in 2014 and that entered a new stage one year ago, currently centres on questions of weaponry. Who else will send tanks? And what about fighter aircrafts? No? Yes? When?

In classical military ethics, which has long been dominated by the so called Just War Theory, these questions fall under ius in bello, the right conduct in war. This also includes discussions on proportionality, military necessity and the differentiation between combatants and non-combatants.

Just War Theory has a long tradition in Christian thought. Church Father Ambrose argued that whoever does not ward off injustice from his fellow man (or woman for that matter) when he can, is as guilty as he who commits it. Ambrose’s student, Augustine, then developed this thought in more detail as he laid the foundations for what could be called a bellum iustum, a just war.

Even before going to war, the criteria of the ius ad bellum, the right to go to war, must be satisfied. These include, for instance, a just cause, legitimate authority, prospect of success, right intention and last resort. We encounter these criteria again in slightly modified form in our modern international law. In view of these guidelines, of Russia’s breach of international law, and of Ukraine’s right to self-defence, the on-going war in Ukraine clearly seems to be a just war. Or is it?

Nothing holy or just

Two points need to be made in this discussion. Firstly, there are no just or holy wars. Period. Or as 150 churches, after the horrors of the Second World War, put it in Amsterdam in 1948: ‘War is contrary to the will of God.’ Wars are always an evil and an expression of the failure of human beings to strive for peace. This also holds true for the war in Ukraine. And this means that we need a new dimension in the debate, namely guilt.

Every action – and inaction – here involves guilt. As the German pastor Dietrich Bonhoeffer, who was killed by the Nazis for his engagement in a plot against Hitler, put it:

‘everyone who acts responsibly becomes guilty’.

And even if we become guilty for the sake of the other person, our guilt remains just the same. Yet, as Bonhoeffer concludes, we trust in the grace of God, who calls us to responsible action. , Bonhoeffer’s ideas have been considered dangerous and easily misused to justify any crime, as forgiveness is always available. Nevertheless, we must acknowledge the reality of guilt that pervades any war, including the war in Ukraine.

Just Peace

Secondly, recent years have seen a new kid on the block: Just Peace Theory. While Just War Theory looks at a conflict from the perspective of violence, Just Peace Theory puts the focus on peace. This includes adding a third set of criteria. Ius post bellum looks at justice after a war. We know that after a conflict is before a conflict. We therefore need to pay more attention to what happens after the weapons finally fall silent.

Here, the experiences of truth and reconciliation processes worldwide can help. Both dimensions belong inseparably together and both already begin during a conflict, not just after it. Truth, for example, requires the documentation of war crimes committed by all parties to ensure the prosecution of war criminals later on. And reconciliation is the conditio sine qua non for sustainable peace.

Russia’s war against Ukraine and its threats against NATO and Western countries demonstrate, not least that after the end of the Cold War, opportunities for genuine and sustainable reconciliation were missed as latent hatred, prejudices and stereotypes were allowed to linger.

Just Peace Theory emphasizes that building peace is an art and a craft. It requires specific skills, training and preparation. It also requires virtues of grace, persistence and forgiveness, Countless documented examples world-wide supply empirical proof that these methods actually work. Perhaps it is worth devoting some of the $2,113 billion (2021) of global annual military expenditure for training non-military approaches to address conflict resolution? To learn how to build peace as much as how to wage war? No? Yes? When?

Pathways to Peace

One such initiative is Pathways to Peace. Aiming at peace, justice and reconciliation in times of war, this initiative is currently being developed through the Conference of European Churches, a group of some 120 member churches in 38 countries. With their long-term involvement and intimate knowledge at the grassroot level, faith actors in civil society seem uniquely positioned to connect people, heal relationships, offer a new social imaginary and facilitate practical help.

The objectives of Pathways to Peace include among others to facilitate safe spaces for honest exchange between Ukrainian and Russian church leaders, to develop a network of church leaders and other civil society leaders for exchange on the preparation of peace or to bring together European youth, in particular Ukrainian and Russian young refugees.

The immense potential of faith actors in transforming conflict and building sustainable peace seems to have gone largely unnoticed in the public sphere. Given the prominence of faith in this conflict, it is about time that all relevant actors in our societies, including faith-based initiatives, joined forces to counter this major crisis of our time.

University turmoil makes the case for chaplains

Creating space, offering time, across cultures.

As the university sector convulses, what’s the point of their chaplains?

The university chaplains fulfil a role which calls for a unique set of skills, including pastoral imagination, flexibility, and creativity as they respond to various, often unpredicted, challenges. Chaplains occupy a place between highly professional Students Services colleagues at the university - think counsellors, experts on emigration and finances, and local parishes representing diverse theological viewpoints.

Every year, while meeting and greeting international students, one of the earliest tasks for the chaplains is to explain their role, as in non-European languages and cultures there is no equivalent of a “chaplain”. Are the chaplains sort of “spiritual gurus”, “life coaches”, “champions of wellbeing”? What is the real difference for the students and the staff in a secular academic institution, between approaching a chaplain and a professional counsellor?

In addition to all these initial questions that a student might ask, other observers question the role of chaplains in a secular academic institution, for being counterproductive. Why provide and finance a chaplain without any measurable outcomes of his or her work? Whether it is counting confirmations, ensuring Christian faith and values as clearly pronounced, or/and conducting regular acts of worship for the students and staff?

Looking at my daily engagement with the international, diverse community of the students and the staff, there are at least three areas of presence (rather being than doing, adapting famous Gabriel Marcel’s distinction), which illuminate this unique type of vocation.

First, currently British universities are going through a very painful, dramatic time of saving money and redundancies. Chaplaincy is becoming a visible space for emotional support to those who are worried about their immediate future. Students and staff are going through a period of uncertainly, if not confusion, so chaplaincy holds the unique space on the campus to show empathy to those who cry, and to offer time for those who need to speak about their pain.

Secondly, chaplaincy has the privilege of being very creative in the ways of engaging with the local academic community. The memorial services for the students and the staff who died recently are not the formal funerals: yet they allow the participants to speak, play the music, show videos about the departed. There is a real celebration of life, brings consolation to academic colleagues, families and relatives.

Thirdly, unlike other professional services, only chaplaincy is able to show the generosity of time to anyone who comes through the door. That’s because those individuals are welcome as the ‘image’ of God. The rest about that individual is accidental, he or she finds ‘home away of home’ in the space of chaplaincy, because through the eyes of Christian faith: he or she is precious and unique.

What about proclaiming the message about Jesus Christ? There is a story about St Francis of Assis who said to his brothers, while approaching an Italian city: “now we will proclaim the Gospel to all who live in this city”. After that he and his companion marched through the streets in silence. When they left the city, one of his brothers, rather surprised by lack of preaching, asked: “Francis, when did we proclaim the Good News?”. “Our way of walking was the proclamation of our faith”. The way how we greet, spend time with students, talk, joke and pray – reflects that proclamation.
