The Christian texts discussed here offer different accounts of the mind. What they left is a long, lively argument. Paul, writing letters in Greek from around 50 CE, spoke of “spirit, soul, and body” and of “the renewing of your mind.” Later writers fought over whether the soul was made of stuff, whether it existed before birth, and where new souls came from. A monk named Evagrius mapped eight troubling “thoughts,” including one he called acedia. Augustine marveled at his own memory. One Egyptian monastic rule paired care for sick monks with limits on where they could go and who could visit them. And the texts we checked don’t picture death as only light and joy. They expect bodies to be raised and people to be judged.
What words did the first Christians use for the mind?
The oldest Christian writings we have are Paul’s letters. The earliest, 1 Thessalonians, probably dates to around 50 CE; the Gospels came 20 to 30 years later (Martin, Yale lecture 2, ch. 1).
Paul prays that his readers’ “whole spirit, soul, and body be preserved blameless” (1 Thessalonians 5:23). In Greek: pneuma, psychē, sōma (SBL Greek New Testament). He urges Christians in Rome to “be transformed by the renewing of your mind” (Romans 12:2), and the word there is nous (SBLGNT).
Here’s the twist. The dead body, Paul writes, “is sown a natural body; it is raised a spiritual body” (1 Corinthians 15:44). “Spiritual” sounds weightless to us. Yale religious-studies scholar Dale Martin explains that ancient pneuma was a kind of stuff, like air or breath (Martin, Yale lecture 15, ch. 1). Analogy: think less “ghost,” more “the air inside a balloon.” Exactly what Paul pictured is a reading of his words (Plausible). Martin adds that early Christians disagreed about what kind of body would rise.
Where did the dead go?
Not to a paradise with no judgment. In Matthew’s Gospel, a judgment scene ends with some going “into eternal punishment, but the righteous into eternal life” (Matthew 25:46). Paul hopes for resurrection, yet also writes of his “desire to depart and be with Christ” (Philippians 1:23). Neither passage explains how the two hopes fit together.
Later writers kept building. Tertullian said souls wait in Hades until judgment day (On the Soul, ch. 58), with one exception: martyrs, he wrote, go straight to paradise (ch. 55). Origen, scholar Mark Edwards writes, expected most souls to pass through a “fiery purification” after death (Edwards, SEP, opening summary).
Christians argued about rituals, too. The Life of Antony says Egyptians honored the bodies of good people, especially martyrs, by wrapping them in linen and keeping them at home instead of burying them. Antony called this wrong and asked for a secret grave, expecting his body back “at the resurrection of the dead” (chs. 90–91). In Milan, Augustine reports, his mother, Monica, brought cakes, bread, and wine to martyrs’ shrines, as was her custom back in Africa. She stopped when Bishop Ambrose banned it, partly because such feasts resembled non-Christian practice (Confessions VI.2). Dying at Ostia, Augustine reports, Monica asked her sons only to remember her “at the Lord’s altar” (IX.11).
Was the soul made of something?
Christian writers borrowed tools from Greek philosophy, then argued with each other.
- Tertullian, a North African writer who died around 220 CE (Tornau, SEP, §6.1), defined the soul as “sprung from the breath of God, immortal, possessing body, having form” (On the Soul, ch. 22). He cited Stoic philosophers for support (ch. 5).
- Origen (c. 185–c. 253), from Alexandria, wrote On First Principles. It survives complete only in Rufinus’s Latin translation (Edwards, §1). Critics later said Origen taught that souls existed before bodies and fell into them. Scholars disagree about whether he held that as doctrine or floated it as a tentative idea (Disputed; §5). He was condemned in or around 553 (§1).
- Augustine weighed where each new soul comes from: made fresh by God for each newborn, passed on by parents, or existing beforehand. He ruled out only one idea: that souls enter bodies as punishment for earlier sins. On the rest, he never took a stand (Tornau, §6.1).
“What is the soul?” wasn’t a mystery they left for us. It was a fight they were already having.
What did Augustine notice about his own mind?
Augustine (354–430) was born in Thagaste, in today’s Algeria, and became bishop of Hippo (Tornau, §1). His Confessions, written around 396–400 (§2), is a prayer that doubles as a life story.
In Book X he explores “the fields and roomy chambers of memory.” Some memories come when called; others “hurry forth in crowds” while he’s hunting for something else (Confessions X.8.12). People travel to marvel at mountains, oceans, and stars, he writes, “and omit to wonder at themselves” (X.8.15).
In City of God, he answered skeptics: “if I am deceived, I am.” You can’t be fooled unless you exist (XI.26). The Stanford Encyclopedia of Philosophy calls this similar to, and probably an inspiration for, Descartes’ famous “I think, therefore I am” (Tornau, §5.1). That influence is Plausible, not proven.
He also left a rare first-person account of grief. When Monica died, he forced back his tears. While the household sang a psalm and friends kept him company, he hid his pain, and he grieved at his own grief. Later, alone, he wept (IX.12). It’s one man’s story, written years later inside a prayer, not a model for everyone.
What was the “noonday demon”?
In the late 300s, Evagrius, a monk teaching monks in Egypt, listed eight tempting thoughts: gluttony, sexual immorality, love of money, sadness, anger, acedia, vainglory, and pride (Praktikos, ch. 6, trans. Dysinger).
The demon of acedia, he writes, is the noonday demon, which he presents as especially burdensome, striking from about 10 a.m. to 2 p.m. (ch. 12). It makes the day feel endless. The monk keeps glancing out the window, sick of his cell and his work, stirring up recent hurts and thoughts of family, dreaming of an easier place. Evagrius tells the monk to remain in his cell despite the temptation to leave (ch. 28).
Was acedia just depression by another name? The evidence we checked can’t show that. Evagrius’s category has its own cause (a demon), setting (a monk’s cell), and remedy (stay put). Whether it matches any modern diagnosis is Unknown.
What can saints’ stories tell us about suffering?
Athanasius says why he wrote the Life of Antony: “for monks the life of Antony is a sufficient pattern of discipline” (prologue). It’s a model to imitate, not a medical file.
The Life blames Antony’s suffering on demons. One night they leave him on the ground, speechless with pain. Then help comes from an ordinary person. The acquaintance who brings his bread carries him to the village church, where relatives and villagers gather. At midnight, only that friend is still awake, watching (ch. 8). In old age, two companions look after him (ch. 91).
Demons and healings run through the book. They show how its author explained suffering. They can’t tell us what condition anyone had, or whether prayer changed it (Unknown).
Did early Christians invent the mental hospital?
The sources we checked don’t show that.
A monastic rule credited to Pachomius, known through Jerome’s Latin, has the superior bring sick monks clothing and food, keeps wine and soup for the infirmary, and says a monk taken ill while traveling should eat apart but be fed abundantly, “so that that sick brother is not saddened” (Rules 42, 45, 46). A sick table-servant may not take food from the kitchen or pantry himself (Rule 41). Sick monks need permission to enter the dining room; they may not carry even fruit back to their rooms or receive visitors, even relatives, without permission (Rules 42–43, 47). Care and control come in one package. Rules show what leaders required, not what sick monks lived through.
In a funeral speech for Basil, bishop of Caesarea in Cappadocia, Gregory of Nazianzus praised a “new city,” a charitable complex just outside town, where pooled wealth supported Basil’s care for the sick, including people with leprosy. Gregory says such people had been driven from cities, homes, fountains, and their own families (Oration 43.63). A funeral speech is praise. It can’t tell us who lived or worked there, or what residents thought. This passage alone does not settle how to classify the institution.
Myth check. “Basil built the first psychiatric hospital.” No source we checked describes an early Christian place set up for what we’d now call mental illness. That’s a limit of the evidence, not proof no such place existed (Unknown).
How we know
What survives: letters and Gospels copied by hand for centuries; treatises, sermons, a saint’s life, a monk’s manual, monastic rules, a funeral speech. Most quotations here come from 19th-century public-domain translations or openly posted modern ones, not current critical editions.
Whose voices are missing: Sick monks, people with leprosy, and people said to be troubled by demons speak only through bishops, monks, and rule-makers. Monica’s last words reach us through her son. These selected passages do not give residents of the charitable complex or sick monks their own account of care. Christians writing in Syriac, Coptic, Armenian, and Ethiopic aren’t covered here yet.
How power shaped the record: After Origen’s condemnation, more of his writing may have been lost. On First Principles survives complete only in Rufinus’s Latin, translated “not always with fidelity” (Edwards, §1). So some of what we read as Origen may be Rufinus’s wording.
Living tradition: Many Christians read these texts today within living traditions. This page describes historical texts, not present-day belief or practice.
The modern bookshelf: E. B. Pusey (1800–1882) translated the Confessions (Gutenberg #3296). Frederick Crombie’s translation of On First Principles appeared in 1869 in The Writings of Origen (Gutenberg #70561). They were translators, not founders of the study of the mind.
Then vs. now
| What texts said or people did then | How that compares with current evidence |
|---|---|
| Mind-talk was spread across spirit, soul, body, and nous. Some writers said the soul was made of fine stuff. | Neuroscience calls the brain “the seat of intelligence, interpreter of the senses, initiator of body movement, and controller of behavior” (NINDS). Whether people have a soul is a religious and philosophical question this page doesn’t settle. |
| Augustine explored memory from the inside. | Researchers also study memory in the brain; NINDS calls the hippocampus a “memory indexer.” Augustine’s account is self-observation, not anatomy. |
| Acedia was a demon-driven temptation, to be fought by staying in your cell. | It isn’t a diagnosis. Any match to a modern condition is Unknown. |
| Saints’ lives blamed suffering on demons and told of healings. | These stories can’t identify an illness or show a cure worked. This page doesn’t evaluate prayer as treatment. |
| Monastic rules paired food and attendants with limits on movement and visits. | Rules show what leaders required, not what sick monks experienced. |
