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.

More marches might just make the point about peace

Protest marches highlight conflict close to home, as commentators cast around for agents of peace. George Pitcher thinks he might just know who they are.

The Home Front of the Gaza war opened up in Britain last weekend. There had been pro-Palestinian marches since the conflict began on 7th October, but for many here it remained the equivalent of a “phoney war”, waged thousands of miles away.

What brought it home were the threats to civil order presented to us over the Remembrance weekend. We now know that the end was drawing nigh for home secretary Suella Braverman when she wrote in The Times last week that the police response to self-styled peace marchers was inadequate.

Whether or not her words inflamed far-right yobs to attack police at the Cenotaph is a matter of conjecture, but that and the massive pro-Palestine protest last Saturday leave no doubt that Israel’s military response to the Hamas atrocities on its people is now a very live issue on British soil.

Many of us have consequently spent this week wondering about the right and proper way to respond to these events. We are, in a way, spoilt for commentary. Paul Goodman wrote presciently in The Times at the start of the week that there had always been a policy fault line between prime minister Rishi Sunak and his home secretary, just ahead of their political tectonic plates shifting, precipitating Braverman’s condemnatory earthquake of her former boss’s alleged betrayal and weakness.

No one can be left in any doubt that there is now support for Hamas terrorism and racist intimidation of Jews on British streets. As a people, we can’t sit idly by and witness this development. The big question is what we do to protect the peace and who does it. Goodman concluded his piece by writing this:

"We are waiting for someone, somehow, to help bring people of all kinds, ordinary Muslims not least, into a great political alliance of moderation, decency, sense and, yes, Britishness. Who is this saviour? Your guess is as good as mine."

In an otherwise excellent piece, I’m tempted to respond to this pay-off thus: Well, duh! It’s almost like someone saying wistfully, in response to the challenges of illegal immigration which the UK faces, that if only there was some kind of pan-European federation of which we could be a member in order to sort the problem out collectively. The answer to that is staring us in the face, as is the answer to the question Goodman raises.

I’d hope I don’t have to spell it out. It is the duty, even the obligation, of a state that has the Christian Church established in law as its moral arbiter to deploy those who witness to its faith as peacemakers between the potentially warring factions in our midst. If that means getting between Hamas sympathisers, racist yobs and frightened Jews who may or may not be Zionists, then so be it.

We should confront in peace, though firmly, those who chant racist and hateful slogans. We should be visible in our demand for peace; that demand made to our polity, to our people and the United Nations.

Though we should not rejoice in it, this is our moment. So is this nation visible in its Christian witness to peace and reconciliation, to the defence of the helpless and innocent at the hands of those who would do them harm and would kill them? I’m afraid not.

True, the House of Bishops of the Church of England has issued an unequivocal statement on the last day of October, calling for a kind of peace. It calls for the release of Israeli prisoners held by Hamas; for “humanitarian pauses” in the conflict to allow for the evacuation of suffering civilians; for safe areas for them and for the observance of “international humanitarian law”.

But it stops short of calling for ceasefire. Why? Is there not a gospel imperative that the killing has to stop? But, anyway, the truth is that these are just words. We are called to action too.

The organisers of the pro-Palestinian protests in the UK to date have called them peace marches. From what I’ve witnessed so far, I’ve no doubt that the vast majority of participants are doing just that – marching for peace.

The Church should either join them, or organise its own peace marches, led by the cross, alongside people of all faiths and none. We should confront in peace, though firmly, those who chant racist and hateful slogans. We should be visible in our demand for peace; that demand made to our polity, to our people and the United Nations.

Perhaps it is too much to hope that this leadership comes from our bishops. It may need to be a movement from the base up, the way Christian witness has been most effective throughout its history. Last weekend, a friend of mine visited a town-wide church celebration, “flags of all nations on the walls, 500 folk… a mix of elderly 1980s Charismatics, trendy Anglicans, plain Baptists and independents, African diaspora Pentecostals, young hipsters of all ethnicities”.

This is where the hope will come from, (in every sense) the peaceful mass. So, when the estimable Mr Goodman asks rhetorically “who is this saviour?”, our answer should be clear: It’s ours.
