The Man Who Didn't Ruin Sex (But Got Blamed For It Anyway)

For fifteen hundred years, Augustine of Hippo has been held responsible for Western Christianity's discomfort with sexuality. The actual story is stranger — and more useful.

Augustine of Hippo died in 430 CE, and he has been blamed for a great many things since. The guilt Catholics carry into confession. The evangelical teenager who has memorised a list of things her body is not allowed to want. The long cultural afterlife of the idea that sex is something the flesh does despite the spirit, rather than something a whole person chooses. The summary verdict, delivered with varying degrees of sophistication across two centuries of intellectual history, is that Augustine made the West afraid of its body. The historians have a more complicated finding, and it matters more than you might think.

Start with what Augustine actually argued, as opposed to what people say he argued. His position, stated plainly, was that sexuality is good but disordered. Not evil. Not condemned. Not a stain on the soul. What the Fall introduced — the doctrine that has shaped Western sexual theology more than anything else — was not the existence of sex but a disruption to its proper function. Before the Fall, in Augustine's telling, Adam and Eve could have had sex without the involuntary character of sexual arousal, without the loss of rational control that desire involves. After the Fall, that control was lost. The problem was not pleasure; it was the body's unwillingness to fully obey the will. This is a strange doctrine, and it has caused enormous harm. But it is not a condemnation of sexuality, and the popular version — that Augustine was a prude, a woman-hater, a Platonic dualist who thought matter was corrupt and sex was dirty — is a later invention. "This is news for many people today," writes one of his recent biographers, "who imagine Augustine as being behind many of our problems with sexuality." The caricature is doing work that the original cannot fully justify. How did this happen? Partly through the process that the historians call post-Augustinian elaboration — medieval canon lawyers, scholastic theologians, Counter-Reformation confessors who took Augustine's contextual polemical arguments and systematised them into a sexual doctrine far more restrictive than anything he wrote. The man who said sexuality was good but disordered became the authority for positions he never held. And partly through the nature of controversy itself: Augustine developed his harshest positions on concupiscence and original sin in the heat of a polemical battle with a theologian named Pelagius and his followers, who argued for a more optimistic view of human moral capacity. He was led, as one historian notes, "to extremes of statement" — arguments shaped by the fight more than by calm reflection. The distortion then became the tradition. Later generations read the extreme statements and missed the context.

Meanwhile, fifteen hundred years later, researchers have started measuring what this tradition actually does to people. The finding that most surprised me, reading through the empirical psychology literature, concerns what they call moral incongruence. The hypothesis, developed by a psychologist named Joshua Grubbs, is this: the distress religious people experience around sexual behaviour is driven not primarily by the behaviour itself but by the gap between the behaviour and the person's sense of who they are morally. In other words: it is not what you do that produces the shame. It is the mismatch between what you do and what you believe you should be. Grubbs tested this with pornography use, because it is relatively easy to measure and because religious populations report disproportionate distress about it. What he found was that the single strongest predictor of feeling addicted to pornography — of experiencing it as compulsive, out of control, a source of genuine suffering — was not how much pornography a person actually used. It was how strongly they morally disapproved of it. High religiosity, high moral disapproval, and self-reports of addiction all clustered together even in people whose actual use was moderate or infrequent. The shame is coming from inside the house. The theology has been internalised as a standard against which all behaviour is measured and found wanting. A pre-registered study — the most rigorous kind, where researchers commit to their methods before seeing the data, preventing them from cherry-picking results — confirmed this finding at the highest level of confidence the field currently offers. Moral disapproval predicts perceived compulsivity more reliably than actual behaviour. The doctrine is doing more causal work than the sex.

The researcher who found the mechanism explaining how this gets into the body is named Jessica Woo, and her finding is the kind of thing that seems obvious once you see it. Higher religiosity predicts lower sexual desire. That relationship, in her data, is statistically explained by a single variable: sex guilt. The internalised belief that sexual pleasure is wrong suppresses desire. The suppression is experienced as a moral achievement by people who cannot easily distinguish between theological virtue and psychological inhibition. What feels like purity is, at the biological level, an inhibitory mechanism doing exactly what it was trained to do. This is the Augustinian heritage made physiological. A doctrine about the will's inability to govern the body has produced, in its descendants fifteen centuries later, a population whose bodies have learned to govern themselves.

Now here is where it gets complicated, and where the simple story — Christianity makes people ashamed of sex — turns out to be only half of what the data show. The same researchers who documented the shame and inhibition pathways have also documented something they call the sanctification of sexuality — the effect of approaching sexual experience within a committed relationship as something sacred rather than threatening. When religiosity operates through this pathway — when the theological message is not "your body is disordered" but "your intimacy is participated in something holy" — the data show the opposite of shame. Higher satisfaction. Lower distress. More integrated sexual experience. The summary of this finding, from a 2020 study that tracked both pathways simultaneously, is that religion is a double-edged instrument. The same tradition can activate either the sex-guilt pathway (which suppresses desire and amplifies shame) or the sanctification pathway (which deepens satisfaction and reduces shame), and which one a given person experiences appears to depend almost entirely on which aspect of the theology they were taught to emphasise. This is not a comfortable finding for either critics or defenders of religious sexual ethics. It says that "Christianity produces sexual shame" is true, and that "Christianity can deepen sexual wellbeing" is also true, and that what determines which one you get is more about pastoral formation than doctrine. The Augustine who said sexuality is good but disordered could, in principle, support either pathway. The question is what his interpreters told you to do with the disorder.

The contemporary expression of this history is what researchers have started calling purity culture — the specific socialisation regime of American evangelical Christianity from roughly the 1990s onward, with its purity pledges, its modesty rules, its "I Kissed Dating Goodbye" and "True Love Waits" campaigns and its frank equation of sexual desire with spiritual danger. The research on purity culture has now moved from qualitative interviews — women describing, movingly and specifically, what it did to them — to measurable outcomes. The findings are unambiguous. Purity culture internalisation predicts lower marital satisfaction and lower sexual satisfaction in adult women. It predicts greater experience of sexual pain. It predicts higher rates of rape myth acceptance — the tendency to misattribute responsibility for sexual assault to victims — among Christian respondents. For sexual and gender minority people raised in evangelical contexts, purity culture's effects are documented as "particularly severe," producing shame and conflict over embodiment that does not resolve with the passage of time. The one finding from this literature that has penetrated public consciousness — from research conducted in the early 2000s — is that teenagers who took virginity pledges had similar rates of sexual behaviour to those who didn't, but significantly lower rates of contraceptive use when they had sex, producing worse sexual health outcomes than if they had never pledged. The purity formation did not produce the behaviour change it promised. It produced shame, ignorance, and the health consequences of both.

What nobody has yet been able to study is whether any of this can be undone. The reclamation literature — feminist theology, queer theology, sex-positive Christian writing, the clinical pastoral models that have sprung up to treat what their authors call religious sexual shame — makes a compelling case for what should work. Rosemary Radford Ruether argued in 1983 that body-soul dualism is a Platonic contamination of authentic Christianity, and that recovering the goodness of the body is theological recovery, not innovation. Nadia Bolz-Weber, writing for a popular audience in 2019, called sexual shame a heresy — not the tradition but a distortion of it. A clinical researcher named Tina Schermer Sellers developed a treatment model for conservative Christian couples built on theological reframing. But no controlled study has yet shown that any of this works. The closest evidence is a finding that gay men who have successfully integrated their religious and sexual identities — who have found some way to hold both — show lower shame than those for whom the identities remain in conflict. Integration is protective. The question is how to achieve it, and for that question, the peer-reviewed literature has almost nothing to say. This is the gap the historical and empirical literatures leave open: we know how the shame was installed, we know the mechanisms by which it operates on desire and behaviour, we know the doctrines that could in principle support either shame or its opposite. What we do not know is whether telling people the true history of how it all happened — that Augustine was more complicated than the caricature, that the caricature caused more damage than the original, that the tradition contains the resources for its own correction — actually changes anything. That is an empirical question. It has not been asked.

Augustine himself, reading the body of scholarship about him, would likely be puzzled by his own legacy. A man who wrote extensively about grace — about the human inability to save oneself, the gift of something freely given — ended up bequeathing to Western Christianity a sexual theology whose central message is that the human body is a problem requiring management. He was writing about something else. The management got added later. Whether that is a consolation depends on how you feel about legacy. The shame arrived from somewhere. It was made by human decisions, theological and institutional, over centuries. What is made can, in principle, be unmade. The research says: probably. The research also says: we haven't tested it yet.

The historical scholarship reviewed here includes Peter Brown's The Body and Society, Kyle Harper's From Shame to Sin, and Diarmaid MacCulloch's Lower than the Angels. The empirical research includes published studies in the Archives of Sexual Behavior, the Journal of Sex Research, and Psychology of Religion and Spirituality.
