Peace and the Sheathed Sword: Budō in a Christian School

Imagine a school shaped by a Christian ethos. Its mission speaks of peace, dignity, moral formation, and care for neighbour. It rejects violence not merely as imprudent but as contrary to human flourishing.

Now imagine a proposal that students might study budō — not as street self-defence, not as competitive fighting, but as a disciplined martial art rooted in restraint, hierarchy, repetition, and self-mastery.

Is there a contradiction?

At first glance, perhaps. Martial arts train the capacity to strike. Christian education seeks to form the conscience away from harm. The optics are uneasy. Yet beneath the surface lies a deeper question — not about bruises, but about anthropology.

Christianity has never spoken with one voice on violence. Across history, it has held at least two distinct moral trajectories. One tradition — most visible in pacifist movements such as the Religious Society of Friends — insists that participation in violence is incompatible with discipleship. Peace is preserved by refusal. One simply does not take up the sword.

Another tradition — articulated most clearly in Augustine and Aquinas — accepts that force may, under strict moral conditions, be used in defence of the innocent. Here, violence is never celebrated, but neither is it categorically excluded. It is morally tragic, tightly bound, and sometimes necessary.

I write from within the Roman Catholic tradition — a tradition that developed just war theory as a moral attempt to regulate the use of force, yet whose historical record reveals how often those limits were strained, ignored, or manipulated. Crusades, religious wars, political entanglements: the Church has not always embodied the restraint it theologised. That history matters. It cautions against moral triumphalism in either direction.

Most Christian schools today operate, whether consciously or not, within this Augustinian inheritance. They teach virtue, justice, courage, and self-control. They field rugby and hockey teams without perceiving contradiction. Physical contest is framed as discipline rather than aggression.

The difficulty with budō is not injury. Controlled dojo practice often produces fewer serious injuries than collision sports. The difficulty is symbolic. Budō carries an explicit lineage of combat. It trains techniques that, in another context, could cause harm. The question, therefore, becomes whether the cultivation of such capacity is already a moral compromise.
Here, the tension sharpens.

One regime of thought holds that peace is safeguarded through abstention. If one refuses the sword entirely, one cannot misuse it. Moral clarity lies in distance from force. To rehearse violence, even in ritualised form, risks normalising it.

Another regime holds that force, as a human capacity, does not vanish by being ignored. Strength exists. Anger exists. The potential for harm exists. The question is not whether these capacities are present, but whether they are disciplined. Peace, in this view, is secured not by denial but by mastery.

Budō belongs to this second logic.

At its philosophical best, it is not the celebration of aggression but the training of restraint. Repetition tempers impulse. Hierarchy humbles ego. Ritual slows reaction. One learns precisely how much force is possible — and therefore how grave its misuse would be. The highest expression of skill is often the refusal to strike.

Everything turns on telos — on the end toward which the practice is ordered. If the end is domination, spectacle, or personal superiority, then it stands in tension with Christian anthropology. If the end is the disciplined formation of character in service of peace, the contradiction is far less obvious.

This is not alien to Christianity. Monastic traditions cultivated bodily discipline through fasting, silence, obedience, and structured hardship. The aim was not punishment but purification of desire. The body became the site where will was trained. Budō functions analogously as a corporeal asceticism: through physical form, the self is governed.

The New Testament does not present a systematic theory of violence; it presents actions that later theology must interpret. Christ refuses retaliation at his arrest and commands Peter to put away the sword. Yet he also confronts injustice forcefully and disrupts the Temple in a dramatic prophetic gesture. The Gospels leave space for ethical development. Christian history filled that space in divergent ways.

It must also be admitted that the cultivation of force always carries danger. Discipline can slide into pride. Technical mastery can inflate ego. A martial framework without humility becomes caricature. But refusal carries danger as well. Moral abstention can drift into abstraction, detached from the embodied realities of conflict and responsibility.

The disagreement, then, is not between peace and violence. It is between two visions of how peace is secured.

Peace can be imagined as the refusal of power.

It can also be imagined as the disciplined governance of power.

Within a Christian educational setting, this becomes a question of formation. What kind of person is the school trying to produce?

A person who never touches the sword, believing that purity lies in abstention?

Or a person who understands the weight of the sword so thoroughly that it remains sheathed?
The Roman Catholic tradition, for all its historical failures, has long held that strength itself is not evil; it is its ordering that determines its morality. The tragedy of history is not that power existed, but that it was so often disordered.

Yet there remains a further question — perhaps the most uncomfortable one. Can one meaningfully guide others through the realities of conflict without ever having encountered its mechanics? Peace formed entirely in abstraction risks fragility. Restraint that has never wrestled, even in disciplined form, with the dynamics of force may prove thinner than it appears. There is a difference between refusing violence. After all, one cannot wield it and refuse it because one has learned its weight.

What appears at first to be a curricular question is in fact a theological one. It turns on the nature of the human person. Is strength inherently corrupting? Or is strength morally neutral until directed toward good or ill?

The sword, literal or metaphorical, is always dangerous. The Church’s own history testifies to that.

The question is whether peace is best preserved by refusing to touch it — or by learning to hold it without drawing it.

Optics cannot settle that question. It must be answered by anthropology.

And that, perhaps, is a conversation worthy of any Christian school — especially one mindful of its past.

「平和」と「鞘に収められた剣」― キリスト教的学校における武道の位置づけ（要約）本稿は、キリスト教的理念を持つ学校において武道を導入することが矛盾するのか、という思想的問いを扱っている。
キリスト教は歴史的に暴力について一枚岩ではなかった。一方には、すべての暴力参加を拒否する平和主義的伝統（例：クエーカー）がある。もう一方には、アウグスティヌスやトマス・アクィナスに代表される「正戦論」の伝統があり、一定の厳格な条件下でのみ武力行使を認めてきた。
筆者はローマ・カトリックの伝統に属しているが、その歴史は武力を神学的に制限しようとしながらも、必ずしも常にその理想を守ってきたわけではない。この歴史的自覚は、どちらの立場にも単純な道徳的優越を与えない。
武道の問題は、怪我の多寡ではなく「象徴性」にある。ラグビーなどの接触競技が容認される一方で、武道は「戦いの技術」を明示的に扱うため、倫理的緊張が生じる。
ここで二つの「真理の枠組み」が現れる。

1. 平和は「力の拒否」によって守られるとする立場
2. 平和は「力の統御」によって守られるとする立場

武道は後者に属する。武道の目的（テロス）は支配ではなく、自己制御と節度の形成にある。反復訓練、礼法、階層構造は、攻撃性を賛美するのではなく、むしろ抑制するための身体的修養である。
キリスト教の修道的伝統における断食や沈黙の修練と同様に、武道も身体を通して意志を鍛える「身体的禁欲」と理解できる。
しかし最後に、より根本的な問いが残る。
暴力の現実や力の構造を一度も経験したことがないまま、人に平和を教えることは可能なのか。
抽象的な平和は脆いかもしれない。力を知らずにそれを拒否することと、その重みを理解した上でそれを鞘に収めることは同じではない。
結局のところ、この問題は課外活動の可否ではなく、人間観の問題である。
力は本質的に腐敗的なのか。
それとも、方向づけられることで善にも悪にもなり得る中立的なものなのか。
平和とは、剣に触れないことなのか。
それとも、抜かずに持つことを学ぶことなのか。
この問いこそが、キリスト教教育の核心に触れている。
