Throughout the Old Testament, persons fast and wear sackcloth to appease God. Furthermore, the
nazirites were persons who took special vows to, among other things, abstain from alcohol. In the New Testament, Saint
John the Baptist is the most clear example of a person practising corporal mortification. According to Mark 1:6, "John was clothed with a garment of camel’s hair, and had a leather girdle about his loins, and he ate locusts and wild honey" (
DRC). The rule of St.
Augustine of Hippo says: "Subdue your flesh by fasting from meat and drink, so far as your health permits. But if anyone is not able to fast, at least let him take no food out of meal time, unless he is sick."
St. Dominic Loricatus (995–1060) is said to have performed "one hundred years penance" by chanting 20
psalters accompanied by 300,000
lashes over six days. Later,
Saint Francis of Assisi, who is said to have received
stigmata, painful wounds like those of Jesus Christ, is said to have asked pardon to his body, whom he called "Brother Ass", for the severe self-afflicted penances he has done: vigils, fasts, frequent flagellations and the use of a
hairshirt. A
Doctor of the Church, St.
Catherine of Siena (died 1380), was a
Dominican tertiary who lived in the way of a
consecrated virgin and practiced austerities which a prioress would probably not have permitted. She is notable for fasting and subsisting for long periods of time on nothing but the
Blessed Sacrament. St. Catherine of Siena wore sackcloth and scourged herself three times daily in imitation of St. Dominic. In the sixteenth century, Saint
Thomas More, the Lord Chancellor of England, wore a
hairshirt, deliberately mortifying his body. He also used the
discipline.
Saint Ignatius of Loyola while in
Manresa in 1522 is known to have practiced severe mortifications. In the Litany prayers to Saint Ignatius he is praised as being "constant in the practice of corporal penance." He was in the habit of wearing a cord tied below the knee. : her motto was "Lord, either let me suffer or let me die". Saint
Teresa of Ávila, (1515–1582) a Doctor of the Church, undertook severe mortification once it was suggested by friends that her supernatural ecstasies were of diabolical origin. She continued until
Francis Borgia, a
Jesuit, reassured her. She believed she was goaded by angels and had a passion to conform her life to the sufferings of Jesus, with a motto associated with her: "Lord, either let me suffer or let me die." St.
Marguerite Marie Alacoque (22 July 1647 October – 17 October 1690), the promoter of the devotion to the Sacred Heart, practised in secret severe corporal mortification after her First Communion at the age of nine, until becoming paralyzed, which confined her to bed for four years. She was eventually cured and she attributed it to the intercession of the Virgin Mary. Afterwards, in honor of her worshiped heavenly host, she changed her name to Mary and vowed to be devoted lifelong to her. St.
Junípero Serra (November 24, 1713 – August 28, 1784), a Franciscan friar who founded the mission chain in Alta California, was known for his love for mortification, self-denial and absolute trust in God. A notable saint in the nineteenth century was St.
Jean Vianney who converted hundreds of people in
laicist France.
Pope John XXIII said of him: "You cannot begin to speak of St. John Mary Vianney without automatically calling to mind the picture of a priest who was outstanding in a unique way in voluntary affliction of his body; his only motives were the love of God and the desire for the salvation of the souls of his neighbors, and this led him to abstain almost completely from food and from sleep, to carry out the harshest kinds of penances, and to deny himself with great strength of soul... [T]his way of life is particularly successful in bringing many men who have been drawn away by the allurement of error and vice back to the path of good living." During the later part of the nineteenth century, Saint
Therese of the Child Jesus, another Doctor of the Church, at three years of age was described by her mother: "Even Thérèse is anxious to practice mortification." Therese later wrote: "My God, I will not be a saint by halves. I am not afraid of suffering for Thee." In the early twentieth century, the child seers of
Fatima said they had initially seen an angel, who said: "In every way you can offer sacrifice to God in
reparation for the sins by which He is offended, and in supplication for sinners. In this way you will bring peace to our country, for I am its guardian angel, the Angel of Portugal. Above all,
bear and accept with patience the sufferings God will send you."
Lucia Santos later reported that the idea of making sacrifices was repeated several times by the Virgin Mary and that she had shown them a vision of
hell which prompted them to ever more stringent self-mortifications to save souls. Among many other practices, Lucia wrote that she and her cousins wore tight cords around their waists, flogged themselves with stinging nettles, gave their lunches to beggars and abstained from drinking water on hot days. Lucia wrote that Mary said God was pleased with their sacrifices and bodily penances. At the latter half of the twentieth century, Saint
Josemaría Escrivá practiced self-flagellation and used the
cilice, a modern-day version of the
hairshirt.
Saint Pio of Pietrelcina, a saint who received the
stigmata wrote in one of his letters: "Let us now consider what we must do to ensure that the
Holy Spirit may dwell in our souls. It can all be summed up in mortification of the flesh with its vices and concupiscences, and in guarding against a selfish spirit ... The mortification must be constant and steady, not intermittent, and it must last for one's whole life. Moreover, the perfect Christian must not be satisfied with a kind of mortification which merely appears to be severe. He must make sure that it hurts." Like St. Josemaria, Padre Pio and
Mother Teresa of Calcutta used the
cilice and
discipline regularly as means of doing penance. Some branches of Christianity have also institutionalized the practice of self-inflicted
penance and corporal mortification through their mandate on fasting and abstinence for specific days of the year. Christian communities in some parts of the world still practice processions of public flagellation during
Lent and
Holy Week. ==20th-century Catholic documents==
