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.

Here’s what Pope Leo really needs, and it’s not our speculation

What the media analysis misses when projecting on to the new pope.

Jack Chisnall

Jack Chisnall is a former gag teller and Oxford Theology graduate, combining the two at Holy Fooling.

Vatican Media.

If memory serves, there was a very positive feeling about Pope Francis when he was elected in 2013. Mind you, I had just started my first year at university and was passionately atheistic - I had flunked my ‘General Studies’ A-Level essay purely because I had nothing to say in favour of the proposal that heaven exists. It was plain enough to me that it was all unscientific wish-fulfilment - so a requirement to give balance had to be jettisoned.

But the late Pope was so adept at doing things that sent a message, that even in my sphere it became commonly agreed that he was a breath of fresh air. Anyone would tell you that he was very down-to-earth. PR types can only dream of that kind of cache among those who have zero interest in what the company is selling.

The less ostentatious popemobile!

The refusal to live in the official papal apartments!

Here was a man clearly wanting to step back from pomp, and the wealth (all that Vatican gold!).

It is only now that, as a Catholic, I have an inside track perspective on how more complicated this all actually was. Some in the Church found some of the public piety unsettling. All churches have a trade-off to make between the gospel directive to not value treasure on earth, as well as a gospel directive to give honour to God using all of our humanity, which might involve using our sense of beauty.

But I am not saying I agree or disagree with any of this. Francis was making a point, and it was well made. I am rather saying that there is a tendency sometimes to think of a pontiff in ill-fitting terms - often political ones. As an atheist, I crammed things into a binary of ‘good, stripped-down rationalisation’ versus ‘bad, mythological and weird’. Especially in secular media, there is a tendency to make popes answers to questions that the media have asked, and not the ones of the Church. The story is always more intricate than ‘liberal’ versus ‘conservative’. Francis was not, in the end, the moderniser some commentariat hoped for, but only because he demonstrated what should have already been obvious: that that the Pope is not ‘in charge of’ the Catholic Faith like that.

At any rate, speculation of a similar kind is already booming around the new Pope, Leo XIV. Everyone is trying to read into every micro-detail we have. What is the significance of his being an American? Is this the conclave’s attempt to create a counter-Trump? Why did Leo come out in traditional garb (which Francis made a point of eschewing)? Why ‘Leo’?

Rumours have already abounded that this new Pope likes to do his private masses in the old Latin; others have pointed out that he ran with Francis’ crowd - and even his opening speech touched on the late Pope’s theme of ‘synodality.’ Synodality, depending on who you ask, is either a noble attempt at decentralisation and listening to the full range of voices in the Church - or an attempt to sneak doctrinal change under the guise of being pastoral.

My advice is to stay well away from it all. Perhaps I’m bringing my own personal journey in too much here - but people change their minds all the time. I wouldn’t want someone to judge me on that General Studies essay now, let me tell you. People especially change when given such a task as Robert Prevost has been given. Even on a purely natural view, being handed responsibility for over a billion Catholics is likely to have a sobering effect, and make one hyper-aware of every move one is about to make.

But, more importantly, on a supernatural lens, Catholics will want to say that this Pope has been, at the very least, permitted by the Holy Spirit. Benedict XVI put it as dismally as this, in 1997:

"Probably the only assurance [the Holy Spirit] offers is that the thing cannot be totally ruined.”

Pope Leo’s ability to shepherd the Church is not a power he enjoys on his own - it comes, as the official teaching has it, “by virtue of his office.” He gets it purely from God, and by existing in relationship to a bigger thing, the Church. It is a difficult thing to make sense of, but the Catholic view of the Pope is not really a statement about human power. It is the belief that, at some very foundational level of analysis, Jesus has agreed not to abandon those who follow him; agreed not to “leave us as orphans." The Pope has come to be seen, in time, as that foundation; as that ‘rock’. But he should always be seen within the bigger picture of God’s promises to us.

For the meantime, the Pope needs not analysis, second-guessing, or projections. He needs prayers.
