For years, critics of the Cass Review have pointed to opposition from the British Medical Association as proof that the review had already been “debunked” or rejected by serious medicine.
That talking point just took a major hit.
According to reporting in The Guardian, the BMA has now dropped its opposition to the Cass Review after conducting its own examination of the evidence.
That is no small development.
For several years, the review led by Hilary Cass has occupied the center of the international debate over pediatric gender medicine. Commissioned by England’s National Health Service, the Cass Review examined the scientific evidence behind puberty blockers, cross-sex hormones, and the broader “gender-affirming” treatment model being used on minors.
Its conclusions were deeply concerning.
The review found that:
the evidence base for puberty blockers and cross-sex hormones in children was weak,
many studies cited in support of these interventions were of low quality,
long-term outcome data were insufficient,
and many children presenting with gender distress also suffered from significant psychological comorbidities requiring more comprehensive assessment.
In response, the UK sharply restricted the use of puberty blockers for minors outside formal clinical research settings.
That alone should have forced a serious and sober public conversation.
Instead, much of the response from activists and ideological allies was not scientific engagement, but moral denunciation.
Doctors, therapists, journalists, parents, and researchers who raised concerns about pediatric transition medicine were frequently branded “transphobic,” accused of hatred, or treated as though they were participating in some kind of moral panic. Public pressure campaigns attempted to frame the debate as already settled:
“The science is settled.”
But the science was not settled.
And increasingly, institutions are being forced to admit it.
The significance of the BMA’s shift is not merely political. It reflects something deeper: the growing inability to sustain the claim that meaningful scientific disagreement never existed.
The Cass Review did not deny that gender-distressed children are suffering. Quite the opposite. It acknowledged profound distress and vulnerability among these young people. But it also recognized that many of them were dealing with overlapping conditions and influences — autism spectrum disorders, depression, anxiety, trauma histories, social contagion dynamics, family dysfunction, and other mental health struggles.
For years, the debate was framed emotionally:
“Do you support transgender youth, or not?”
But that framing obscured the real question:
“What treatment model genuinely helps vulnerable children in the long term?”
That is the question serious medicine must answer.
Not ideological slogans. Not online intimidation campaigns. Not institutional fear.
Evidence.
A Deeper Truth
One of the deeper issues underneath this entire debate is philosophical — even theological. Modern gender ideology often treats the body itself as secondary to the inner self, reducing biological sex to something psychologically negotiable rather than something meaningful and given.
The Cass Review did not address theology. But in practice, it forced medicine back toward reality:
Bodies matter. Puberty matters. Development matters. Biology matters.
The tragedy is that this debate should have happened years earlier.
Instead, legitimate scientific concerns were too often suppressed by institutional fear, activist pressure, and ideological conformity. Many clinicians stayed silent. Some lost jobs or reputations for speaking carefully and cautiously. Parents who hesitated were sometimes treated as obstacles rather than protectors.
Meanwhile, vulnerable children were placed on pathways involving irreversible physical changes whose long-term consequences remain poorly understood.
The ground is shifting now.
Slowly. Unevenly. Quietly in some places.
But it is shifting.
And perhaps one of the lessons of this entire controversy is that medicine becomes dangerous when it confuses compassion with unquestioning affirmation — or when political ideology is allowed to outrun scientific evidence.
Children deserve better than slogans. They deserve truth, compassion, humility, and genuine care.
If you walked into a hospital and asked, “What is medicine for?”—most people would offer some version of the same answer: to heal what’s broken.
But what if medicine stopped healing and started interrupting?
What if a medical intervention didn’t restore nature, but halted it?
And what if the patients were children?
That’s the debate surroundingKing’s College London’s new trial on puberty blockers for 226 kids under sixteen—a trial whose central question is not whether puberty blockers should be used, but when they should be administered.
And that, right there, reveals everything.
Today, we need to talk about why puberty blockers are not just risky, not just poorly evidenced, and not just morally incoherent—but why they are, in the deepest Christian sense, bad medicine.
1. Medicine that heals—which restores a natural process that’s gone wrong.
2. Medicine that disrupts—which interrupts a natural process on purpose.
Restorative medicine is Christian through and through. Jesus heals. The Church heals. Doctors heal. And we are thankful for all of that.
But the trial at King’s College isn’t trying to heal anything.
Puberty isn’t a disease. It’s not a malfunction. It’s not an affliction. It’s the God-designed process by which a child becomes an adult in body, mind, and soul.
Harrington notes that puberty is a “complex set of naturally occurring changes intrinsic to the human genetic template.” But the King’s College trial doesn’t ask whether halting these changes is moral or wise. It only asks:
Should we delay puberty blockers—or give them earlier?
And there’s the problem: the worldview underneath the trial has already decided that human nature is raw material—neutral matter that exists for us to re-engineer.
But Christians don’t believe in engineering the human being.
We believe in receiving what God has made.
NOTICERS VS. ENGINEERS
Harrington describes two kinds of people in this debate: Noticers and Engineers.
Engineers
Engineers look at the world the way Francis Bacon did in the 17th century:
The world is stuff. Stuff can be rearranged. And the job of science is to overpower nature “for the relief of man’s estate.”
There’s no form.
No telos. (The Greek word for ‘goal’ or ‘end’.)
No given meaning.
Puberty, therefore, isn’t a stage of creaturely development—it’s an expressive option. Something you can modify according to your inner sense of self.
Noticers
Noticers, on the other hand, see the world as Christians have always seen it:
Creation has shape.
Creation has direction.
Creation has purpose.
This is Aristotelian1 Based on the teachings of Greek philosopher Aristotle. It’s Thomistic2Based on the teachings of St. Thomas Aquinas. It’s also John Paul II. (Saint John Paul the Second.3Pope from 1978 to 2005)
It’s Genesis. It’s Jesus. (Gen 1:26-284Then God said, “Let us make man in our image, after our likeness. And let them have dominion over the fish of the sea and over the birds of the heavens and over the livestock and over all the earth and over every creeping thing that creeps on the earth.” So God created man in his own image, in the image of God he created him; male and female he created them. And God blessed them. And God said to them, “Be fruitful and multiply and fill the earth and subdue it, and have dominion over the fish of the sea and over the birds of the heavens and over every living thing that moves on the earth.” ; Matt 19:4-65[Jesus] answered, “Have you not read that he who created them from the beginning made them male and female, and said, ‘Therefore a man shall leave his father and his mother and hold fast to his wife, and the two shall become one flesh’? So they are no longer two but one flesh. What therefore God has joined together, let not man separate.”)
Our bodies are not blank canvases. They are icons—physical revelations of invisible truths. Male and female are not costumes. They are modes of being human.
And as Harrington puts it, even in the most secular scientific contexts:
“Form and ends (telos) never really go away.”
You can deny nature only so long before it comes roaring back.
THE LIMITS OF CONSENT
One of the most powerful parts of Harrington’s argument is her explanation of how our culture replaced metaphysical limits with the single moral requirement of consent.
After the horrors of the 20th century—eugenics, forced sterilizations, and the experiments of Josef Mengele6Josef Mengele was a Nazi physician notorious for brutal experiments at Auschwitz—Western ethics focused intensely on coercion. The logic became:
As long as a subject consents, the action is morally permissible.
But this missed the deeper problem.
The Nazi doctors weren’t evil only because they coerced people. They were evil because they treated human beings as manipulable material—as lab rats.
Here’s the uncomfortable truth:
If your worldview treats the human body as raw material to be reshaped for psychological comfort, you’ve accepted the same metaphysical mistake that drove eugenics.
Harrington writes:
“Never mind consent, it’s an offense not just against that child, but against reality itself: an atrocity only distinguishable from those of Dr Mengele in its having manipulated the victims into seeing it as ‘medicine.’”
That sentence should shake us.
It isn’t hyperbole.
It’s moral clarity:
If children are persuaded to view the disruption of healthy development as “care,” the wrongness isn’t lessened. It is compounded.
Children cannot meaningfully consent to the permanent interruption of their own maturation. You can’t sign a permission slip for your future self.
Consent cannot sanctify what violates nature.
THE CASS REVIEW: WHAT IT REVEALED (AND WHERE IT STOPPED SHORT)
In 2024, the Cass Review shook the UK medical establishment by revealing that the evidence base for “gender-affirming care” in minors was astonishingly weak.
It found:
• No robust evidence that puberty blockers improve mental health.
• No convincing data that blockers reduce suicide risk. (The primary concern)
• Significant concerns about bone density, cognitive development, and fertility.
• A clinical model driven more by ideology than by science.
As a result, puberty blockers were banned in the UK—but only until better data could be gathered. And there’s the rub!
King’s College London intends to gather that data.
But here’s the problem:
Cass framed the issue as uncertainty. Christian anthropology frames it as impossibility.
You don’t need “more data” to know that interrupting a child’s sexual maturation is a violation of creaturely design.
The Cass Review was a step in the right direction, but from a Christian point of view, it didn’t go nearly far enough. It never asked the foundational question:
Should we be medicalizing gender distress at all—especially through interventions that halt the very process by which a child becomes an adult?
THE METAPHYSICAL FAULT LINE
Here is Harrington’s most important passage, which I’ll read in full:
“The nub of the King’s College debate, then, isn’t over trial design, or consent. It’s a metaphysical disagreement so deep as to be irreconcilable. Is there any difference between using a drug to restore normal health in a child with cancer or premature puberty, and using the same drug to induce abnormal puberty-less-ness in a child who simply believes themselves to be the opposite sex?”
Mary Harrington
That is a razor-sharp question.
Now to the Engineer, perhaps, there is no difference.
To the Christian—noticer, realist, creature—the difference is everything.
A cancer drug given to correct disease is medicine. A cancer drug given to abolish normal development is harm.
And Harrington continues:
“The engineers… say it’s all just ‘healthcare.’ But noticers of human nature respond: no, puberty is not an illness… It’s an aspect of our form and telos.”
Form. Telos. Purpose.
Puberty is the God-given road by which childhood becomes adulthood.
It is ordered toward future vocation, future parenthood, future communion between male and female.
To interrupt it is not compassion.
It is, quite literally, a denial of human nature.
WHAT THE CHURCH MUST SAY
So what do we do with all of this?
First: We tell the truth.
We tell the truth about the body. We tell the truth about creation. We tell the truth about the limits of consent. We tell the truth about the dangers of engineering the human being.
Second: We care for hurting children with compassion—not affirmation of falsehood. A child in distress deserves love, stability, patient listening, and the promise that their body is not their enemy.
Third: We reject the false choice between cruelty and “affirmation.”
There is a third way: truthful love.
Love that does not lie about creation. Love that does not cooperate with gender ideology. Love that sees the child not as an identity project, but as a creature of God.
Finally: We remember that the body is an icon, a revelation.
Your body is not a problem to solve.
It is a gift to receive.
It is a form that speaks.
It is a telos that unfolds.
Puberty is one of God’s good words spoken into creation.
It is not ours to erase.
+++
Psalm 139 says,
“You knit me together in my mother’s womb. I praise you, for I am fearfully and wonderfully made.”
To receive the body is to receive God’s work.
To reject the body is to reject His wisdom.
And to interrupt a child’s development is to tamper with what God Himself has ordained.
May the Church be a place of clarity, courage, and compassion—a place where children are protected, where truth is spoken, and where the human body is honored as the handiwork of the Creator.
Thanks for listening.
If this episode was helpful, please share it—and join me next time as we continue forming a distinctly Christian imagination for the world God made.
As a Christian I would argue that it is impossible to change sex or gender. I would never support puberty blockers or surgery for someone who wishes to change what they were given, a normal functional body.
The UK is finally coming around. David Bell, former president of the British Psychoanalytic Society has written a piece in The Guardian (hardly a right-wing rag). He finishes by saying:
“In years to come we will look back at the damage done to children with incredulity and horror.”
But will we hold people accountable for that horror?
