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.

From transferring footballers to AI talent, we over-value each other

Building our value on cashflow crumbles our self-esteem

Premier League footballers not only have millions of pounds, but millions of accountants. Yes, that's right: I've had my morning coffee and the editor didn't miss that sentence. There are millions of armchair accountants. You know, the bean counters many of us effortlessly transform into when it's transfer season.

Pick your channel - everyone seems to be asking 'is Rasmus Højlund really worth that much?' Your heart mightn't bleed for him - as he is handsomely compensated - but at least spare a thought for him and the crushing weight of critics and their expectations of his performance.

Footballers aren't alone. Whether it's bankers' bonuses, the excesses of the offers to top AI engineers… OpenAI CEO Sam Altman claims that Meta have offered his employees bonuses of $100 million to recruit them. Other recent valuations of companies have raised $1 and $2 billion. The Economist says that AI valuations are 'verging on the unhinged’.

Armchair accountants actually look a lot like jurors. But who are we to judge? The figures might seem silly money, but the stakes are higher than fantasy football or Monopoly. In Build the Life You Want, Arthur Brooks and Oprah Winfrey call out the way we objectify people at work over performance or pay:

'It’s pretty easy to see why we shouldn’t objectify others. Less obvious but equally troubling is when the objectifier and the person being objectified are one and the same—when you objectify yourself.'

Building our value on cashflow, Instagram likes and the like crumbles our self-esteem and all the health and social issues that come with that. In the arena of our own workplace, they write that self-objectification 'is a tyranny. We become a terrible boss to ourselves, with little mercy or love.’

You only have to peer into the comments section any any online article (not just sport) to see how callous and unforgiving apparently polite, middle-class society has become. It's hard not to have the sneaking suspicion that our devaluing of others thinly veils the way we've devalued ourselves.

The way out of this is to detach our value from our pay and work. So, take Rasmus Højlund, transferred to Manchester United in 2023 for £64million. I would argue his worth is a lot more than £64 million. But that is because his performance, for this exercise, is irrelevant. This is not a new notion. For millennia, the Christian notion of grace is not only the entry-point of faith, but the operating system, with perfect performance already having been achieved by a saviour. The 'ultimate price', paid by God, is of such immeasurable worth and value that Rasmus, or any of us, are worth significantly more than £64million.

But then the problem arises that Christians can still struggle with feeling like an expensive disappointment, unable to live up to the spiritual 'transfer fee'. Is it really worth me accepting the biblical claims of the price paid by Jesus on the cross if I just pile on guilt? Well, if you feel like a star signing, you've probably missed the point. But equally, if you feel like a flop, there's the need to recognise that value and worth was never rooted in your performance in the first place. There's a very different set of rules. It's not a zero-sum game of competition where players and managers are ruthlessly eliminated. The Bible paints the picture of a God not so much ruthless as he is reckless.

When Jesus tells the parable of the prodigal son, squandering his father's wealth, only to be welcomed, restored and celebrated with open arms, the word 'prodigal' that's been attached to this parable even more appropriately describes the father: 'recklessly extravagant' and 'having spent everything'. Whatever our own estimations – or those of others – actually don't matter. £64million might feel like an absurd and unreal amount of money – but it isn't Monopoly money. Those figures have actually been transferred. And just because we can't see or feel the price that has been paid, doesn't make it any less real or consequential. Not only is your guilt traded away from you, but your rights to self-judge.
