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.

There’s more than one way to lose our humanity

How we treat immigrants and how AI might treat humans weighs on the mind of George Pitcher.

“The greatness of humanity,” said Mahatma Gandhi, “is not in being human, but in being humane.” At first glance, this is something of a truism. But actually Gandhi neatly elides the two meanings of humanity in this tight little phrase.

Humanity means both the created order that we know as the human race and its capacity for self-sacrificial love and compassion. In the Christian tradition, we celebrate at Christmas what we call the incarnation – the divine sharing of the human experience in the birth of the Christ child.

Our God shares our humanity and in doing so, shows his humanity in the form of a universal and unconditional love for his people. So, it’s an act both for humanity and of humanity.

This Christmas, there are two very public issues in which humanity has gone missing in both senses. And it’s as well to acknowledge them as we approach the feast. That’s in part a confessional act; where we identify a loss of humanity, in both its definitions, we can resolve to do something about it. Christmas is a good time to do that.

The first is our loss of humanity in the framing of legislation to end illegal immigration to the UK. The second is the absence of humanity in the development of artificial intelligence. The former is about political acts that are inhumane and the latter goes to the nature of what it is to be human.

We have literally lost a human to our inhumanity, hanged in a floating communal bathroom. It’s enough to make us look away from the crib, shamed rather than affirmed in our humanity.

There is a cynical political line that the principal intention of the government’s Safety of Rwanda (Asylum and Immigration) Bill, voted through the House of Commons this week, is humane, in that it’s aimed at stopping the loss of life among migrants exploited by criminal gangs. But it commodifies human beings, turning them into cargo to be exported elsewhere. That may not be a crime – the law has yet to be tested – but it is at least an offence against humanity.

Where humanity, meaning what it is to be human, is sapped, hope withers into despair. When a human being is treated as so much freight, its value not only diminishes objectively but so does its self-worth. The suicide of an asylum seeker on the detention barge Bibby Stockholm in Portland Harbour is a consequence of depreciated humanity. Not that we can expect to hear any official contrition for that.

To paraphrase Gandhi, when we cease to be humane we lose our humanity. And we have literally lost a human to our inhumanity, hanged in a floating communal bathroom. It’s enough to make us look away from the crib, shamed rather than affirmed in our humanity.

That’s inhumanity in the sense of being inhumane. Turning now to humanity in the sense of what it means to be human, we’re faced with the prospect of artificial intelligence which not only replicates but replaces human thought and function.

To be truly God-like, AI would need to allow itself to suffer and to die on humanity’s part.

The rumoured cause of the ousting of CEO Sam Altman last month from OpenAI (before his hasty reinstatement just five days later) was his involvement in a shadowy project called Q-star, GPT-5 technology that is said to push dangerously into the territory of human intelligence.

But AI’s central liability is that it lacks humanity. It is literally inhuman, rather than inhumane. We should take no comfort in that because that’s exactly where its peril lies. Consciousness is a defining factor of humanity. AI doesn’t have it and that’s what makes it so dangerous.

To “think” infinitely quicker across unlimited data and imitate the best of human creativity, all without knowing that it’s doing so, is a daunting technology. It begins to look like a future in which humanity becomes subservient to its technology – and that’s indeed dystopian.

But we risk missing a point when our technology meets our theology. It’s often said that AI has the potential to take on God-like qualities. This relates to the prospect of its supposed omniscience. Another way of putting that is that it has the potential to be all-powerful.

The trouble with that argument is that it takes no account of the divine quality of being all-loving too, which in its inhumanity AI cannot hope to replicate. In the Christmastide incarnation, God (as Emmanuel, or “God with us”) comes to serve, not to be served. If you’ll excuse the pun, you won’t find that mission on a computer server.

Furthermore, to be truly God-like, AI would need to allow itself to suffer and to die on humanity’s part, albeit to defeat its death in a salvific way. Sorry, but that isn’t going to happen. We must be careful with AI precisely because it’s inhuman, not because it’s too human.

Part of what we celebrate at Christmas is our humanity and, in doing so, we may re-locate it. We need to do that if we are to treat refugees with humanity and to re-affirm that humanity’s intelligence is anything but artificial. Merry Christmas.
