The Woman Who Refused to Be Silent: Hildegard of Bingen

In 1148, a cloistered Benedictine nun sat down and wrote a letter to Bernard of Clairvaux – the most powerful churchman in Europe, a man who had launched crusades and toppled popes with his words. She told him she had been receiving divine visions since childhood and that God had commanded her to write them down. She asked for his endorsement.

Bernard gave it. Pope Eugenius III personally authorised her to continue. And just like that, a woman who was not permitted to preach, teach theology, or claim religious authority had official Church permission to do all three.

Her name was Hildegard of Bingen. She was forty-seven years old. She was just getting started.

The isolation of those early years is easy to underestimate from a modern vantage point. This was not simply a quiet religious upbringing. It was deliberate, structural confinement.

She had been experiencing visions from early childhood – vivid, luminous phenomena she described as a "living light" or a "reflection of the living light." Modern medical historians have proposed, with reasonable plausibility though without certainty, that her experiences were consistent with migraines accompanied by visual aura phenomena. Hildegard herself offers no such clinical framing. To her, and to everyone around her, the visions were divine.

She grew up under Jutta's tutelage, took her vows, and when Jutta died in 1136, Hildegard was elected magistra – leader – of the small community of women that had formed around them. She was thirty-eight years old and had spent thirty years enclosed in a cell and its modest expansions. By the standards of her world, she had lived an entirely unremarkable religious life.

Then, in 1141, came the vision she described as transformative: a command to "say and write" what she saw. She had been recording her visions privately for years, with the help of a monk named Volmar who acted as her secretary and editor. Now she was being instructed, she believed, to go public.

The strategy Hildegard employed to gain that permission is, in itself, a masterclass in working within a system while fundamentally subverting it. She didn't claim personal authority – she claimed divine mandate. She wasn't teaching her own theology; she was transcribing God's words. The distinction was crucial. A woman asserting her own religious insight was transgression. A woman acting as God's vessel was an entirely different proposition, and one medieval theology had to take seriously.

The letter to Bernard was the key move. His endorsement did not just open doors – it provided cover. When Eugenius III read excerpts of her visions aloud at the Synod of Trier in 1147 or 1148 and gave his approval, Hildegard acquired something extraordinary: papal authorisation for a woman to write and publish theology. It was, by the standards of the twelfth century, almost without precedent.

The resulting work, Scivias – Know the Ways – took ten years to complete. It comprises twenty-six visions exploring the relationship between God, humanity, and salvation, accompanied by vivid illuminated illustrations that Hildegard directed and may have partially executed herself. The manuscript that survives in copies is visually unlike anything else from the period: dense with imagery, theological ambition, and a voice that is unmistakably personal even through layers of Latin formality.

What makes Hildegard genuinely difficult to categorise is the sheer breadth of what she produced – and that papal mandate, once granted, seems to have unlocked something. With the Church's formal permission to transcribe the voice of God, she moved through music, science, and linguistics with a confidence that very few women of the era were afforded. The divine authority wasn't just cover for theology. It was a key that opened everything.

Her musical output alone is astonishing. Around seventy-seven compositions survive – one of the largest repertoires attributed to any named composer from the medieval period, and compositions that pushed well beyond the conventions of their era. Where Gregorian chant typically operated within a modest melodic range, Hildegard's music reached across two and a half octaves, using dramatic leaps and long, soaring melodic lines that feel almost Romantic in their emotional ambition. The Ordo Virtutum – the Play of the Virtues – is a liturgical drama in which personified virtues battle for a human soul against the Devil. It is one of the earliest surviving examples of what we might now recognise as music drama, predating the development of opera by four centuries.

She wrote two major scientific and medical works: Physica and Causae et Curae, cataloguing hundreds of plants, stones, animals, and treatments, drawing on classical sources but also on her own practical observation. Historians still argue over how much of it reflects actual clinical practice versus theological theory, but make no mistake: these were substantive, highly detailed documents, not just a few marginal notes on herbal tea.

Then there is the Lingua Ignota – the Unknown Language. Hildegard created a constructed language of around nine hundred words, accompanied by a novel alphabet she called the Litterae Ignotae. Its purpose remains genuinely uncertain. Scholars have proposed various explanations: a mystical or devotional tool, a means of private communication among her community, an expression of the restless creative energy that ran through everything she did. No text of any length survives in it, which makes interpretation difficult. What is clear is that inventing a language with its own script is not something most people do, in any century.

Perhaps the most audacious thing Hildegard did – more audacious, in some ways, than the theological writing, because it happened in public and in person – were her preaching tours. Between roughly 1158 and 1163, she undertook at least four documented journeys through Germany, speaking at monasteries, churches, and cathedrals. She addressed clergy. She addressed mixed audiences. She told them to reform their corrupt institutions. She named specific failures and demanded specific changes.

This was not permitted. Women did not preach to mixed or clerical audiences in the twelfth century. Hildegard's justification, consistently maintained, was that God was speaking through her because the men who should have been speaking had failed. She was, in her own framing, a feather carried on divine breath – the agency was not hers but God's. The Church tolerated it. No one moved to silence her.

Her correspondence was similarly unintimidated. She wrote to Frederick Barbarossa, Holy Roman Emperor, warning him against a path she considered destructive. She wrote to multiple popes with frank assessments of their failings. These letters survive. They are not deferential.

In the last year of her life, Hildegard picked one more battle – and it was a serious one.

She had permitted the burial in her convent's cemetery of a young nobleman who had previously been excommunicated but who, she maintained, had sincerely repented before his death and received last rites. The local bishops disagreed with her assessment. They ordered the body exhumed. Hildegard refused. She went further: she personally walked through the cemetery and erased the grave markings with her staff so that the bishops' representatives would not be able to locate the body.

The bishops responded by placing her entire convent under interdict – one of the most severe sanctions the Church could impose, forbidding the community from receiving communion and, devastatingly for a composer and musician, from singing the Divine Office. For Hildegard, the silencing of her community's music was not merely a legal punishment. It was a direct assault on something she considered sacred.

She fought back with a long, passionate letter to the bishops arguing her case on theological grounds, insisting that the man had died in a state of grace and that the interdict was unjust. She won. The interdict was lifted just months before her death in September 1179. She was around eighty-one years old.

Even at the end, the Church blinked first.

Hildegard died on 17 September 1179. Attempts to canonise her began shortly after her death and continued, intermittently, for centuries. The formal process stalled repeatedly, for reasons that are not entirely clear from the surviving record. It was not until 7 October 2012 that Pope Benedict XVI officially declared her a saint and, simultaneously, a Doctor of the Church – the highest theological honour the Catholic Church can bestow, and one that only thirty-seven people have ever received. She was the fourth woman to be named a Doctor of the Church, after Teresa of Ávila, Catherine of Siena, and Thérèse of Lisieux.

Eight hundred and thirty-three years is a long time to wait for institutional recognition. Hildegard spent most of that time being studied, performed, and discussed regardless.

I find this story difficult to summarise neatly, which is probably appropriate. The temptation with figures like Hildegard is to reach for the "ahead of her time" framing – the woman who should have lived in a more enlightened era. But I'm not sure that quite captures it. She was extraordinarily of her time, in the sense that she used every tool her specific moment offered – the theology, the mystical tradition, the patronage structures, the Benedictine intellectual culture – and pushed each of them further than anyone expected.

She didn't transcend the medieval world. She worked inside it with such extraordinary capability that the medieval world had very little choice but to accommodate her. Right up until the very end, when she stood in a graveyard erasing grave markers with her staff rather than submit to an order she considered unjust.

The official documentation eventually caught up. It just took a while.
