The patron saint of doctors is St. Luke the Evangelist, whom St. Paul calls "the beloved physician." Physicians and surgeons also claim Sts. Cosmas and Damian, twin doctors who treated the sick for free and died as martyrs, along with St. Pantaleon, St. José Gregorio Hernández, "the doctor of the poor," and St. Gianna Molla, a pediatrician and mother.

Patron saints of doctors, physicians and surgeons

"For all healing is from God," says the Book of Sirach, and the Church has always seen the doctor's work as a share in Christ's own. He went through Galilee healing every disease, and he told his disciples to do the same. The saints who are patrons of doctors were physicians themselves: an evangelist, twin brothers who would take no fee, a young court doctor, a Venezuelan professor who carried medicine to the poor on foot, and a mother who practiced pediatrics until weeks before she died.

St. Luke, the patron saint of doctors

St. Luke, the author of the third Gospel and the Acts of the Apostles, is the best-known patron of physicians and surgeons, and the reason is a single line of Scripture. Writing from prison, St. Paul sends greetings from his companion (Colossians 4:14, Douay-Rheims):

Luke, the most dear physician, saluteth you: and Demas.

Other translations render it "the beloved physician." Early writers built on that line. Eusebius, around 325, says Luke was of Antiochene family and "a physician by profession," and St. Jerome says the same. Scholars have long noticed that Luke's Gospel describes illnesses with a doctor's care. He alone tells us that Peter's mother-in-law had "a great fever," and he alone records Christ's proverb "Physician, heal thyself."

Luke is also the patron of artists, from the tradition that he painted the Virgin Mary. His feast is October 18, and many Catholic hospitals and medical guilds bear his name; the annual White Mass for health-care workers is often held near his feast.

Sts. Cosmas and Damian, the twin physicians

Sts. Cosmas and Damian were twin brothers and doctors in Roman Cilicia, on the coast of present-day Turkey. They treated the sick, and by tradition even animals, without charging anything, so Greek Christians called them the anargyroi, "the silverless" or "unmercenaries." Under Diocletian, probably around 287 or 303, they were arrested and beheaded. Their cult spread fast. In the 520s Pope Felix IV built a basilica in their honor in the Roman Forum, and their names stand in the Roman Canon of the Mass.

Their most famous miracle is traditional. The Golden Legend (about 1260) tells how, long after their deaths, they appeared to a man who served in their church in Rome, whose leg was eaten away by disease, and replaced it with the healthy leg of a man buried that day. Painters loved the scene, which is why surgeons in particular claim the twins. Their feast is September 26.

Other patron saints of doctors

St. Pantaleon

St. Pantaleon, called Panteleimon in the East, was a physician of Nicomedia martyred around 305. Tradition makes him a court doctor who, once converted, treated the poor without charge. The Orthodox venerate him as "Greatmartyr and Healer," and in the West he is one of the Fourteen Holy Helpers and a patron of physicians and midwives. His feast is July 27.

St. José Gregorio Hernández

St. José Gregorio Hernández (1864–1919) is the newest patron of doctors and one of the most loved. Born in the Andean village of Isnotú, he studied medicine in Caracas and then, sent by the Venezuelan government in 1889, studied microbiology and experimental physiology in Paris and Berlin. He came home to found modern laboratory teaching at the University of Caracas. He was a Secular Franciscan who went to Mass daily, treated the poor for nothing and often paid for their medicine. On June 29, 1919, while carrying medicine to a sick patient, he was struck by a car and killed. Pope Leo XIV canonized him on October 19, 2025, and Venezuelans call him simply "the doctor of the poor."

St. Gianna Beretta Molla

St. Gianna Molla earned her degree in medicine and surgery at the University of Pavia in 1949, specialized in pediatrics at Milan in 1952 and ran a clinic at Mesero, near Magenta. She married Pietro Molla in 1955 and had four children. During her last pregnancy a fibroma was found on her uterus, and she asked the doctors to save her baby whatever happened to her. She died in 1962, a week after her daughter was born, and was canonized in 2004. Catholic physicians' guilds, especially pro-life doctors, take her as patron.

St. Blaise, St. Raphael and St. Roch

St. Blaise was, by tradition, a physician before he became bishop of Sebaste, and St. Raphael the Archangel, whose name means "God heals," cured Tobit's blindness in the Book of Tobit. St. Roch, who by tradition nursed plague victims in Italy, appears on lists of patrons of surgeons. All three appear among the patrons of physicians in this encyclopedia.

A prayer for doctors

The Church's oldest prayer-word for physicians is Scripture itself (Sirach 38:1-4, Douay-Rheims):

Honour the physician for the need thou hast of him: for the most High hath created him. For all healing is from God, and he shall receive gifts of the king. The skill of the physician shall lift up his head, and in the sight of great men he shall be praised. The most High hath created medicines out of the earth, and a wise man will not abhor them.

The Orthodox troparion of Cosmas and Damian is short enough to say walking down a hospital corridor: "Holy unmercenaries and wonderworkers, Cosmas and Damian, heal our infirmities. Freely you have received; freely you give to us." More prayers are on the pages of St. Luke and Sts. Cosmas and Damian.

Let us ask St. Luke and Sts. Cosmas and Damian to pray for every doctor, surgeon and medical student, and for the patients in their care. See also our patron saint of nurses, patron saint of healing and patron saint of cancer pages, and all the patron saints.
