I Believe in a Strong Distinction Between Physiological and Psychiatric Diagnoses

I believe there must be a strong and principled distinction between physiological diagnoses and psychiatric diagnoses. This distinction is not a minor technical matter. It goes to the heart of how we understand man, suffering, sin, responsibility, medicine, and the authority of Scripture. The modern psychiatric framework often speaks as though emotional anguish, fear, despair, compulsive behavior, anger, rebellion, grief, guilt, and spiritual misery are diseases in the same basic sense as cancer, diabetes, epilepsy, infection, or organ failure. I reject that assumption.

A physiological diagnosis identifies an actual disorder of the body. It deals with disease, injury, infection, structural abnormality, organ dysfunction, measurable biochemical malfunction, or some other bodily condition that can ordinarily be tested, observed, imaged, cultured, biopsied, or otherwise medically verified. A broken bone is not merely a description of behavior. A tumor is not a metaphor. Diabetes is not simply a cluster of emotional complaints. These are bodily realities.

Psychiatric diagnoses are different in kind. They are generally descriptive categories assigned to patterns of thought, feeling, behavior, mood, perception, fear, desire, or distress. They do not usually identify a known bodily disease process. They are labels for experiences and behaviors, not proven medical explanations for them. To call depression, anxiety, or attention problems “illnesses” in the same sense as pneumonia or heart failure is to blur categories that ought to remain distinct.

This distinction matters because the psychiatric model has often borrowed the authority of medicine without providing the same kind of objective medical evidence. The popular “chemical imbalance” explanation is one of the clearest examples. For decades, countless people were told or led to believe that depression and other psychiatric struggles were caused by a chemical imbalance in the brain. Yet that explanation has not been empirically established. A major umbrella review on the serotonin theory of depression concluded that the research did not provide convincing evidence that depression is caused by low serotonin or reduced serotonin activity. Even University College London’s summary of that research stated that there was “no clear evidence” that serotonin levels or activity are responsible for depression.

This does not mean people do not suffer. They do. Deeply. It does not mean despair is fake, anxiety is imaginary, or anguish is insignificant. The issue is not whether people suffer; the issue is how we interpret that suffering. The Bible gives us a much richer and truer vocabulary than the psychiatric system. Scripture speaks of sin, guilt, shame, fear, sorrow, despair, grief, folly, rebellion, bitterness, idolatry, unbelief, weakness, oppression, temptation, conscience, repentance, faith, endurance, hope, and worship. These are not primitive categories waiting to be replaced by psychiatry. They are God-given categories for understanding human beings before Him.

I also believe psychiatric medication, regardless of its perceived therapeutic effects, is fundamentally harmful. This does not require denying that some people may feel relief, sedation, emotional blunting, stimulation, or temporary stabilization from psychiatric drugs. A drug can produce an effect without addressing a true disease. Alcohol can reduce social anxiety. Opiates can create euphoria. Stimulants can increase focus. Sedatives can quiet distress. But a therapeutic effect does not prove that the original problem was a medical disease, nor does it prove that the drug is healing the person.

Psychiatric medication often changes the person’s experience of himself without resolving the moral, spiritual, relational, and worship-related issues at the center of human life. It can numb sorrow without teaching lament. It can reduce anxiety without producing trust in God. It can mute guilt without leading to repentance. It can quiet the conscience without cleansing it through the blood of Christ. It can alter behavior without addressing the heart. In this way, psychiatric medication can become not merely medically questionable, but spiritually dangerous.

The Christian must be especially concerned about any system that redefines sin as sickness, guilt as pathology, fear as chemistry, and rebellion as disorder. Once man’s fundamental problem is relocated from the heart before God to the brain as a medical mechanism, the gospel is displaced. The sinner no longer primarily needs forgiveness, reconciliation, repentance, and renewal; he needs management, treatment, diagnosis, and medication. This shift is not neutral. It changes the entire framework of care.

A biblical view of man must begin with creation, fall, redemption, and restoration. Man is made in the image of God. He is embodied, but he is not merely biological. He is responsible, worshiping, covenantal, moral, and spiritual. His body matters, but his body does not exhaust the meaning of his life. His emotions matter, but they are not self-interpreting. His thoughts matter, but they must be brought captive to Christ. His suffering matters, but suffering must be interpreted under the lordship of God, not merely under the authority of psychiatric theory.

This is why I reject the integrationist tendency to place Scripture alongside psychiatry as though both speak with equal authority about the care of the soul. Medicine may treat the body. Physicians may diagnose bodily disease. But psychiatry frequently claims authority over matters that Scripture already addresses with divine clarity. The care of the soul belongs first to God, His Word, His Spirit, and His church.

At the same time, Christians should speak carefully when addressing those already taking psychiatric drugs. To say that psychiatric medication is harmful is not the same thing as telling people to stop suddenly or recklessly. Abrupt withdrawal can itself produce serious physical and emotional consequences. Even mainstream psychiatric sources acknowledge withdrawal symptoms and advise against sudden discontinuation. Therefore, someone who has been taking these drugs should not be urged into rash action, but should be helped with patience, wisdom, pastoral care, and appropriate medical supervision if they seek to come off them.

The church must recover courage and clarity. We must not mock the suffering. We must not despise the weak. We must not deny the reality of anguish. But neither may we surrender biblical anthropology to a psychiatric system built on unstable theories and descriptive labels. The suffering person needs more than a diagnosis. He needs truth. He needs Christ. He needs the Word of God. He needs the fellowship of the saints. He needs repentance where there is sin, comfort where there is sorrow, courage where there is fear, and hope where there is despair.

I believe the distinction between physiological and psychiatric diagnoses must be defended because without it the church will confuse the body with the soul, sickness with sin, medication with sanctification, and symptom relief with redemption. Christ did not come merely to manage symptoms. He came to redeem sinners, restore worshipers, comfort sufferers, renew minds, cleanse consciences, and reconcile alienated people to God.

A Final Word of Caution

If you or anyone you know is considering quitting psychiatric medication, please do not attempt to do so without a doctor’s assistance. Withdrawing from psychiatric medication can be a dangerous thing to undertake on your own. No one should stop taking their prescribed psychiatric medication suddenly, impulsively, or without wise oversight. Psychiatric medication will produce serious withdrawal effects, and the process of coming off them may need to be gradual, carefully monitored, and medically supervised. And always, if you or someone you know has a psychiatric crisis or is a danger to themselves or others, call 911 immediately. A call today can save a life allowed to live tomorrow. You won’t regret making the call.
