Myth of Mental Illness: What MacArthur, Medical Experts, and the Bible Reveal
1. What John MacArthur Said About Mental Illness
A “Noble Lie” to Medicate People
About 15 months before he died in 2025, Pastor John MacArthur issued a controversial but vital critique of the global rise in depression and suicide that everyone suffering depression needs to hear. He called mental illness a “noble lie,” reviving Dr. Thomas Szasz‘s claim that psychology replaced sin and moral responsibility with diagnoses and drugs.
Genuine brain disease vs psychological conditions
MacArthur distinguished genuine brain disease—such as tumors, dementia, or brain injury—from problems of the mind, which cannot be healed with drugs. He said (psychological) conditions like PTSD, ADHD, and OCD are real struggles, but not brain disorders; they arise from the heart and mind, not chemical imbalance. Guilt, fear, and despair come from separation from God, not biology.
Chemical Imbalance: A Profitable Lie
Mental illness justified by the “chemical imbalance” theory is now discredited and was only a “useful lie,” MacArthur said. He taught that true healing comes through spiritual renewal in Christ, producing the fruit of the Spirit (Galatians 5:22–23).
The Big Business of Drugs
MacArthur also noted that psychiatry has become a profit engine, turning emotional pain into drug markets. The global antidepressant industry made $18 billion in 2024 and is projected to double by 2034 (GMI Insights, 2024). During COVID-19, vaccine and psychiatric drug profits surged—showing the system is profit-driven, not patient-driven (SOMO Report, 2023). [Antidepressants do not work]

2. What Medical Experts Say About Mental Illness
Genetic Heritability for Neuroticism
Evidence shows that vulnerability to mental illness—including a proclivity to anxiety, impulsivity, or depression—is partly heritable (≈30–50%; Behavior Genetics, 2016). Yet research also confirms that mental and emotional patterns can change through behavioral discipline and spiritual renewal (Roberts et al., Psychological Bulletin, 2018; Koenig, Handbook of Religion and Health, 2012).
In short, genes may predispose but do not predetermine. Rather, human weakness reflects the fall, but those in Christ are “a new creation” (2 Corinthians 5:17)—renewed and transformed through faith and obedience.
Szasz Rejected Genetic Link
Dr. Thomas Szasz, psychiatrist and professor at SUNY Upstate Medical University, argued in The Myth of Mental Illness (1961) that only verified biological defects—such as brain tumors or neurological damage—constitute real disease. He rejected the idea that emotions or behavior could be inherited like physical traits, insisting that the mind, being non-physical, cannot be genetically diseased. [List of experts who agree.]
Peterson: It’s Mindset & Personal Responsibility
Psychologist and 12 Rules for Life author Dr. Jordan Peterson does not deny clinical mental illness, but he rejects labeling normal emotional struggles (anger, sadness, insecurity, lack of discipline) as a medical disease.
He teaches that emotional struggle is rarely genetic unless there is clear biological damage, and that psychological suffering comes from “patterns of thought and behavior”—how a person interprets reality and chooses to act (UT lectures, 2017–2019). Therefore, many emotional or “mental” struggles stem from mindset and personal responsibility, not brain defects.
Moncrieff: No consistent evidence on serotonin
In 2022, Dr. Joanna Moncrieff, professor of psychiatry at University College London, led a landmark review published in Molecular Psychiatry, concluding there is no consistent evidence that depression results from low serotonin levels or chemical imbalance (University College London, 2022). Jay E. Adams, founder of the biblical counseling movement, taught that most emotional and behavioral struggles are not biological but spiritual, rooted in the mind and soul (Competent to Counsel, 1970).
Szasz: Not brain diseases but problems in living
Psychiatrist Thomas Szasz argued in The Myth of Mental Illness 1961 that psychiatry often medicalizes moral and existential struggles, framing them as diseases. He contended that many so-called mental illnesses are not literal brain diseases but “problems in living.” [Upstate]
Neurologist and psychiatrist Richard Saul and pediatric neurologist Fred Baughman Jr. have disputed the existence of clear biological markers for certain psychiatric labels, arguing that many diagnoses reflect contextual, behavioral, or environmental factors rather than proven brain disease.
Experts Expanding the “Mental Illness Myth” Perspective
- Dr. Allen Frances (b. 1942) – Former DSM-IV Task Force chair; admitted that psychiatry over-medicalizes behavior: “We have turned temper tantrums and childhood exuberance into psychiatric illness.”
- Dr. Bruce E. Levine (b. 1956) – A Profession Without Reason (2022); said psychiatry sustains control by pathologizing nonconformity and promoting the chemical-imbalance myth.
- Dr. David Healy – Bangor University psychiatrist; Pharmageddon (2012); argued the serotonin-deficiency model was industry-driven, not scientific.
- Dr. David Powlison (1949–2019) – Theologian and editor of the Journal of Biblical Counseling – said that psychological problems reveal spiritual and theological roots.
- Dr. Fred Baughman Jr., a Pediatric neurologist, declared, “There is no scientific evidence that ADHD is a disease—no brain abnormality has ever been found.”
- Dr. Jay E. Adams (1929–2020) – Founder of Christian nouthetic counseling; Competent to Counsel (1970); taught that “mental illness” stems from sin or unbelief, healed through repentance and faith.
- Dr. Jeffrey A. Schaler (b. 1951) – Szasz Under Fire (2004); said the mind can be sick only metaphorically, and psychiatry medicalizes moral conflict.
- Dr. Joanna Moncrieff (b. 1960) – UCL psychiatrist; 2022 Molecular Psychiatry review found no consistent link between serotonin and depression.
- Dr. Peter Breggin (b. 1936) – Toxic Psychiatry (1991); warned that psychiatric drugs cause neurological harm, dependency, and spiritual dullness.
- Dr. R. D. Laing (1927–1989) – The Divided Self (1960); viewed psychosis as a rational response to an irrational society.
- Dr. Richard Saul (1938–2018) – ADHD Does Not Exist (2014); said ADHD symptoms arise from sleep loss, stress, poor diet, or poor teaching, not a brain defect.
- Dr. Sami Timimi (b. 1960) – Naughty Boys (2005); described ADHD as a cultural construct that pathologizes normal childhood behavior.
- Dr. Thomas Armstrong (b. 1951) – The Myth of the ADHD Child (1995); argued behavioral differences reflect developmental and spiritual diversity, not pathology.
- Dr. Thomas Szasz (1920–2012) – The Myth of Mental Illness (1961); said “mental illnesses are metaphorical diseases,” not biological ones.
ROOT CAUSE OF DEPRESSION IN THE BIBLE.
3. What the Bible Says About Mental Illness
Job, David, Elijah, Jonah, Jeremiah, and Paul
Scripture treats anxiety and despair not as biological disorders but as conditions of the soul rooted in separation from God, doubts and fear, unbelief, or sin. Job, David, Elijah, Jonah, Jeremiah, and Paul each faced deep anguish, yet found restoration only by trusting and turning back to God.
Also, those who suffered the most also practiced gratitude. Entitlement and chronic dissatisfaction are associated with poorer well-being (Journal of Positive Psychology, 2017). Scripture explains the root: “They did not honor Him as God or give thanks.” (Romans 1:21). The issue is not hardship—it is a heart without gratitude.
- Job cursed the day of his birth (Job 3:1), yet declared, “I know that my Redeemer lives” (Job 19:25).
- David wept through the night (Psalm 6:6) but found peace when he repented and put his hope in God (Psalm 42:5).
- Elijah, exhausted and hopeless, said, “It is enough; take my life” (1 Kings 19:4), but was renewed by God’s voice and provision.
- Jonah fled in rebellion and begged for death (Jonah 4:3), yet found mercy when he repented.
- Jeremiah, the “weeping prophet,” cried, “Why is my pain unending?” (Jeremiah 15:18), but was strengthened when he recalled God’s steadfast love (Lamentations 3:22–23).
- Apostle Paul confessed being “utterly burdened beyond strength” (2 Corinthians 1:8), yet his suffering deepened his trust in God, “who raises the dead” (2 Corinthians 1:9).
Generational Curse: Ancestral sins do not bind Christians. Christ has already broken every curse (Galatians 3:13). Mental or emotional struggles are not curses passed down. If patterns continue, the issue is ongoing sin or disobedience.
WHAT PAUL SAID ABOUT DEPRESSION.
What Faith-Based Studies Show
Repentance, Confession, and Renewing
Mental illness in Scripture is addressed through spiritual warfare and repentance—a change of mind along with confession and renewed faith. Remember that our struggle is from within (James 1:14-15), but we can overcome by renewing the mind (Romans 12:2), which comes when we ask God to transform our hearts and seal them with humility and a thankful heart. [Mindset of Jesus]
Daily Renewing of the Mind
Faith-based studies document lasting recovery through repentance, forgiveness, and renewal in moral purpose (Koenig, 2012). The mind—spiritual, ethical, and behavioral is the true battleground, where lasting healing comes not through medication but through the daily renewing of the mind.
Therefore, if Christian faith practices produce measurable biological effects that aid mental recovery without medication, the nature of mental struggles is spiritual, not neurological.
- Faith communities build resilience, reduce isolation, and provide emotional support.
- Worship and prayer lower cortisol, improve sleep and mood, and strengthen immune function.
- Healing occurs through spiritual renewal rather than through drugs.
