7 Saints Who Struggled with Lust (and the Practice That Saved Each One)
Seven canonized saints fought lust — and nearly lost. St. Augustine, St. Mary of Egypt, St. Thomas Aquinas, St. Benedict of Nursia, St. Moses the Black, St. Margaret of Cortona, and St. Jerome all battled sexual temptation. But here is what matters for you: each of these saints who struggled with lust won not through a single dramatic moment, but through a specific daily practice they kept for years. Their habits still work today.
St. Augustine: The Man Who Asked God to Wait
Before he became a Doctor of the Church, Augustine spent nearly two decades enslaved to lust. He kept a concubine, fathered a son outside marriage, and prayed the prayer every man fighting this battle recognizes: “Grant me chastity and continence — but not yet” (Confessions, Book VIII). He knew exactly what he was doing and could not stop.
What broke the cycle was not willpower. It was community. His mother Monica prayed for him for seventeen years. His friend Alypius walked with him through conversion. When he finally surrendered in the garden in Milan — hearing “Tolle, lege” (take up and read) — he was not alone. He picked up Romans 13:13–14: “Not in orgies and drunkenness, not in sexual immorality… but put on the Lord Jesus Christ.”
The Practice That Saved Him
Radical honesty with at least one other person. Augustine did not fight in secret. Monica knew. Alypius knew. Ambrose knew. His Confessions is a public reckoning — he wrote his sins for the entire Church to read. The habit: tell one trusted person exactly where you are. Not “I struggle with impurity.” The real version. Secrecy is the fuel of lust; honesty starves it.
St. Mary of Egypt: Forty-Seven Years of Daily Combat
Mary of Egypt was not a quiet sinner. From age twelve, she lived in Alexandria driven by what she described as “an insatiable desire” (Life of St. Mary of Egypt, by St. Sophronius). For seventeen years she pursued sexual pleasure without restraint. Her conversion came during a pilgrimage to Jerusalem, when an invisible force prevented her from entering the Church of the Holy Sepulchre. She heard the Blessed Virgin’s voice and collapsed in repentance.
But conversion was not the end of the battle — it was the beginning. Mary fled into the desert beyond the Jordan River, and for the next forty-seven years she fought against the desires that followed her. She told the monk Zosimas about those early desert years: the cravings for wine, for the songs she used to sing, for the physical pleasures she had known. She fought them with fasting and prayer, sometimes lying face-down in the dust until the temptation passed.
The Practice That Saved Her
Immediate prayer at the moment of temptation — not after. Mary did not wait until evening to examine her conscience. When desire hit, she dropped to the ground and prayed until it left. The habit: when temptation rises, stop and pray one specific prayer — the Hail Mary, the St. Michael Prayer, whatever anchors you. Not later. Now. Temptation loses its grip when you refuse to let even thirty seconds pass in silence.
St. Thomas Aquinas: The Firebrand and the Angels' Cord
Thomas Aquinas is remembered as the greatest theologian in Catholic history. What gets less attention is that his own family tried to destroy his vocation through sexual temptation. When Aquinas was a young Dominican novice, his noble family disapproved of his choice to enter a mendicant order. They imprisoned him for over a year, and as a final measure, sent a woman to seduce him.
Aquinas grabbed a burning log from the fireplace and chased her out. Then he used the brand to sear the sign of the cross into the wall. Tradition records that two angels appeared and girded his waist with a cord of purity. From that day forward, Aquinas was never again seriously troubled by lust.
The Practice That Saved Him
A pre-decided response, executed without deliberation. Aquinas did not debate. He did not weigh options. He acted instantly because the decision had already been made: I will not consent. The habit: decide before the moment exactly what you will do. Delete the app. Leave the room. Put the phone in another room before bed. When the decision is already made, the moment of temptation finds no gap to exploit. Prudence directs us to “avoid occasions of sin” (CCC 1806) — and the best avoidance is a plan made when your mind was clear.
St. Benedict of Nursia: Thorns That Healed
The father of Western monasticism nearly abandoned his vocation because of one woman. As a young hermit living in a cave at Subiaco, Benedict was suddenly seized by the memory of a woman he had once seen. Pope St. Gregory the Great describes the moment in the Dialogues: the memory “mightily inflamed” him with desire, and he came close to leaving his solitary life altogether.
What Benedict did next has shocked readers for fifteen centuries. He threw himself into a thicket of thorns and nettles until his body was torn and bleeding. Gregory writes that “by the wounds of his body, he cured the wounds of his soul.” According to tradition, Benedict was never again troubled by lust in the same way.
The Practice That Saved Him
Redirecting the body’s energy through physical action. You do not need thorn bushes. But Benedict’s insight is real: lust is a physical craving, and physical action can break its hold. The habit: when temptation strikes, move your body. Do pushups. Take a cold shower. Go for a run. Walk to another room. Lust feeds on passivity — on lying in bed, on sitting alone with a screen. Physical movement interrupts the loop. Benedict understood this fifteen hundred years before neuroscience confirmed it.
St. Moses the Black: From Bandit to Desert Father
Moses was a fourth-century Ethiopian who led a gang of bandits in the Egyptian desert. He was known for violence, theft, and sexual excess. After a dramatic conversion, he entered a monastery — but his old desires did not disappear. For years, Moses was tormented by lustful thoughts and violent impulses from his former life.
What set Moses apart was his willingness to be humiliated for the sake of healing. He went repeatedly to his spiritual father, Abbot Isidore, and confessed everything — every thought, every craving, every near-fall. Isidore did not condemn him. He taught Moses to keep vigil through the night in prayer, standing upright, to train his body and soul in vigilance.
The Practice That Saved Him
Nightly examination of conscience, shared with a spiritual director. Moses did not keep a private scoreboard. He laid every struggle before someone wiser. The habit: every night, spend five minutes reviewing where temptation arose — what triggered it, when you were weakest. The Ignatian Examen is built for exactly this (CCC 1454). At least once a week, share what you found with a confessor or director. Patterns you cannot see alone become obvious when spoken aloud.

St. Margaret of Cortona: The Mistress Who Became a Mystic
Margaret spent nine years as the mistress of a young nobleman in Tuscany. She bore his son and was known throughout the region for her beauty and her sin. When her lover was murdered and his dog led her to the body, Margaret’s world collapsed. She returned to her father’s house and was turned away. She walked to the Franciscan friars in Cortona and begged for help.
Her conversion was immediate, but her healing was not. For years, Margaret was tormented by memories of her former life and the fear that God had not truly forgiven her. She submitted to severe penances and went to confession with extraordinary frequency. Her confessor, Fra Giunta Bevegnati, recorded that she returned to the sacrament multiple times each week — not from scrupulosity, but from a deep need to hear God’s mercy spoken aloud.
The Practice That Saved Her
Frequent, specific confession — weekly at minimum. Margaret did not settle for monthly confession or vague accusations. She named her sins precisely and returned to the sacrament often. The habit: go to confession weekly. Not “when you fall” but every week, as a rhythm. Name the specific temptation, the specific failure, the specific circumstance. The sacrament of Reconciliation does not merely forgive — it heals (CCC 1468). Frequency builds transparency, and transparency makes secrecy harder to maintain.
St. Jerome: The Scholar Who Fought Phantoms in the Desert
Jerome is famous for translating the Bible into Latin — the Vulgate, which served the Church for over a thousand years. Less famous is the fact that he fled Rome for the Syrian desert partly because he could not escape sexual fantasies. In Letter 22 to Eustochium, he wrote: “How often, when I was living in the desert… I imagined myself among the pleasures of Rome… My face was pale with fasting, yet my mind was burning with desires.”
Even extreme fasting did not fully resolve the problem. What finally helped was Jerome’s immersion in the study of Scripture — specifically, he began learning Hebrew, an endeavor so demanding that it consumed his mental energy entirely. He replaced idle mental space with rigorous work directed toward God.
The Practice That Saved Him
Replacing idle time with Scripture, not merely adding prayer to an empty schedule. Jerome discovered that lust thrives in mental vacancy. The habit: identify your most vulnerable hours — for most people, late at night — and fill them with something that demands active mental engagement. Scripture reading. A Bible study. The Liturgy of the Hours or Lectio Divina. Not passive scrolling. Active engagement. An occupied mind in conversation with God leaves no room for the enemy.
What These Seven Saints Teach You
Notice what none of these saints did: none of them simply “prayed harder” in the abstract. Every one developed a specific, repeatable practice — accountability, immediate prayer, pre-decided action, physical movement, nightly examen, frequent confession, or Scripture immersion. Their holiness was not the absence of temptation. It was the presence of habits.
Aquinas taught that virtue is a habit — a stable disposition acquired by repeated acts (Summa Theologiae I-II, Q. 55, Art. 1). These saints prove it. They became pure by doing the same small thing, day after day, until grace had ground to work in.
You do not need to roll in thorns or flee to the desert. But you do need a practice — one concrete thing you will do today and tomorrow and the day after. Pick the saint whose struggle most resembles yours. Adopt their habit. Track it. And when you fail, remember: every saint on this list fell before they stood. The difference is they did the practice again.
