The distinction between mental illness and demonic possession has been a subject of intense debate throughout history. In ancient times, civilizations such as the Neolithic Peruvians and various African and Oceanic tribes turned to trepanation—a surgical procedure involving the drilling of holes into the skull—to address mental disturbances. This practice was rooted in the belief that such openings could release the malevolent spirits believed to be tormenting the individual. For centuries, this idea shaped both religious rituals and medical approaches, leaving a profound mark on the intersection of spirituality and early medicine.
In today's era of neuroscience and psychology, the idea that spiritual struggles might manifest as mental disorders has largely been set aside. Instead, we place our trust in medication and clinical treatments alone. But in doing so, have we overlooked an essential truth?

Biblical Insights on Possession and Healing
The Bible recounts numerous instances of individuals experiencing afflictions that, in modern times, would likely be recognized as mental illnesses. However, in the context of that era, such conditions were often interpreted as cases of demonic possession.
In Mark 5:1-20, we encounter the story of a man tormented by a legion of demons. His behavior mirrors symptoms often associated with severe psychosis: self-harm, social isolation, and uncontrollable outbursts. So severe was his condition that he was frequently restrained with chains and shackles, treated much like a prisoner by today’s standards. Yet, it was Christ’s divine intervention alone that brought him true healing and restoration.
In Mark 9:17-18, we read about a boy tormented by a spirit that repeatedly seized him, even throwing him into fire. Jesus, through the power of God, cast out the demon, delivering the boy from his suffering. I believe the power within Jesus was the eternal Christ—the Christ who has worked miracles since the beginning of creation. These verses remind us that mental and emotional struggles often go beyond physical causes, revealing a profound spiritual dimension at their core.
Nevertheless, the advancement of medical science has led society to increasingly dismiss scriptural interpretations of human health and behavior. The Industrial and Scientific Revolutions emphasized observable, testable phenomena, gradually pushing spiritual explanations to the margins. In the 19th century, groundbreaking discoveries by figures like Paul Broca advanced our understanding of neuroscience, solidifying the idea that conditions such as mental illness stem from brain dysfunctions with scientific explanations, rather than divine causes. Although practices like trepanation have faded into obscurity, they leave behind a lingering question: Were ancient peoples entirely misguided, or did they possess profound insights that we have since overlooked?
The Shift from Spiritual to Secular Explanations
Trepanation, though primitive, likely aimed to address both the spiritual and physical aspects of human suffering. The contrasting views of Broca and his colleague P. Barthelemy Prunieres—one attributing the practice to superstition, the other to practical medicine—reflect the enduring tension between faith and science that persists even today.
There was a time when the church led the charge in healing, providing prayers and deliverance for those suffering from unseen forces. Today, that responsibility has shifted to psychiatrists and pharmaceutical companies. Yet, despite significant advancements in medicine and therapy, the mental health crisis continues to escalate. Rates of depression, schizophrenia, and suicide have reached unprecedented levels. This begs the question: have we overlooked the spiritual dimensions that may underlie many of these struggles?
Ephesians 6:12 For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms.
The Call to Reevaluate
Christians should revisit the idea that modern mental health disorders may not stem from chemical imbalances but could be manifestations of spiritual oppression. Medical treatment should not take precedence over spiritual discernment and deliverance. The early Church understood this dynamic, as illustrated in Acts 8:7, where people were healed and delivered from unclean spirits.
James 5:14-15 reminds us: "Is anyone among you sick? Let them call the elders of the church to pray over them and anoint them with oil in the name of the Lord. And the prayer offered in faith will make the sick person well; the Lord will raise them up." This passage emphasizes that healing extends beyond the physical or medical realm, highlighting its deep spiritual significance.
Conclusion: Returning to Truth
In our modern world, the role of demonic forces in human suffering has largely been overlooked. While ancient cultures lacked the scientific language of neuroscience, they possessed a deep awareness of the spiritual battles that continue to this day—battles that often go unacknowledged in contemporary society. We have strayed far from this truth.
In a time when mental health challenges are increasingly prevalent, we must not overlook the timeless wisdom of our ancestors. The Church is called to reclaim its role in healing and deliverance, standing steadfast in the authority and truth of Christ. Only He holds the ultimate power to bring healing to those burdened by what is now understood as mental health struggles, which stem from deeper spiritual afflictions.
