Life

Catharine Benincasa was born at Sienna in 1347, the daughter of James Benincasa, a dyer by trade, and his wife Lapa. [Butler "st-catharine-of-sienna"] Her father, though prosperous in temporal affairs, made the cultivation of virtue in his children his chief solicitude, instructing them in piety both by example and precept. [Butler "st-catharine-of-sienna"] Her mother cherished a particular affection for this daughter above her other children, and the gifts of mind and body with which Catharine was adorned earned her the name Euphrosyna among those who knew her. [Butler "st-catharine-of-sienna"]

From her earliest capacity to know God, she was favoured with extraordinary graces. [Butler "st-catharine-of-sienna"] While still very young, she withdrew to a solitude outside the town to imitate the lives of the desert fathers; returning after some time to her father's house, she continued to be guided by the same spirit. [Butler "st-catharine-of-sienna"] In childhood she consecrated her virginity to God by a private vow, and her love of mortification and prayer manifested sentiments uncommon for so tender an age. [Butler "st-catharine-of-sienna"]

At twelve years her parents determined to arrange her marriage. Finding them deaf to her entreaties that she might remain single, she redoubled her prayers, watching, and austerities, knowing that her protection must come from God alone. [Butler "st-catharine-of-sienna"] Her parents, regarding her inclination to solitude as unsuited to the life they designed for her, sought to divert her from it: they deprived her of the little chamber they had allowed her, loaded her with distracting employments, and laid upon her all the drudgery of the house. [Butler "st-catharine-of-sienna"] The hardest labour, humiliations, contempt, and the insults of her sisters became to her a subject of joy; she embraced crosses of every kind with holy eagerness, and received all railleries with admirable sweetness and heroic patience. [Butler "st-catharine-of-sienna"] What grieved her was the loss of her dear solitude; yet the Holy Ghost taught her to make herself another solitude in her heart, where, amidst all occupations, she considered herself always as alone with God. [Butler "st-catharine-of-sienna"]

The death of her eldest sister, Bonaventura, soon confirmed her in these sentiments. [Butler "st-catharine-of-sienna"] Her father, edified at her patience and virtue, at length approved and seconded her devotion. [Butler "st-catharine-of-sienna"]

Ministry

She began her course of rigorous life before the age of fifteen: her chief sustenance was boiled herbs without sauce or bread, which last she seldom tasted; she wore a rough hair-cloth and a large iron girdle armed with sharp points; she lay on the ground and watched much. [Butler "st-catharine-of-sienna"] Humility, obedience, and denial of her own will gave her penitential austerities their true value. [Butler "st-catharine-of-sienna"] She was visited with many painful distempers, which she underwent with incredible patience, and suffered much from hot baths prescribed by physicians; amidst her pains, she prayed constantly that they might serve for the expiation of her offences and the purifying of her heart. [Butler "st-catharine-of-sienna"]

In 1365, the eighteenth year of her age, she received the habit of the third Order of Saint Dominic in a nunnery contiguous to the Dominicans' convent. [Butler "st-catharine-of-sienna"] From that time her cell became her paradise, prayer her element, and her mortifications knew no restraint. [Butler "st-catharine-of-sienna"] For three years she spoke to no one but God and her confessor; her days and nights were employed in contemplation, the fruits of which were supernatural lights, an ardent love of God, and zeal for the conversion of sinners. [Butler "st-catharine-of-sienna"]

God recompensed her charity to the poor by many miracles, often multiplying provisions in her hands and enabling her to carry loads of corn, oil, and other necessaries beyond her natural strength. [Butler "st-catharine-of-sienna"] She dressed and served an old woman named Tocca, infected with leprosy to such a degree that the magistrates had ordered her removed from the city; this poor wretch returned her tender charity with continual bitter complaints and reproaches, which only moved the saint to greater sweetness and humility. [Butler "st-catharine-of-sienna"] Another, whose infectious cancer she for a long time sucked and dressed, published against her the most infamous calumnies, joined by a sister of the convent; Catharine bore this violent persecution in silence until, by her patience and prayers, she obtained the conversion of both enemies and a retraction of their slanders. [Butler "st-catharine-of-sienna"]

Her ardent charity made her indefatigable in labouring for the conversion of sinners, offering continual tears, prayers, fasts, and austerities for that end. [Butler "st-catharine-of-sienna"] All her discourses, actions, and even her silence powerfully induced men to the love of virtue; according to Pope Pius II, no one ever approached her who went not away better. [Butler "st-catharine-of-sienna"] When Nannes, a powerful turbulent citizen, proved resistant to all her words, she made a sudden pause to offer prayers for him; they were heard that very instant, and an entire change was wrought in the man, who reconciled himself to all his enemies and embraced a penitential life. [Butler "st-catharine-of-sienna"] He later gave her a stately house which, by the pope's authority, she converted into a nunnery. [Butler "st-catharine-of-sienna"]

In 1374, during a pestilence laying waste the country, she devoted herself to serve the infected and obtained of God the cure of several, including two holy Dominicans, Raymund of Capua and Bartholomew of Sienna. [Butler "st-catharine-of-sienna"] Thousands flocked from distant places to hear or see her, brought by her words or example to sincere repentance. [Butler "st-catharine-of-sienna"]

When the people of Florence and Perugia, with much of Tuscany and the Ecclesiastical State, entered into league against the Holy See in 1375, her heart was pierced with bitter sorrow; she had foretold these evils three years before they came to their height. [Butler "st-catharine-of-sienna"] The inhabitants of Sienna and other places were kept within the bounds of duty by her prayers, letters, and exhortations. [Butler "st-catharine-of-sienna"] The Florentine magistrates sent to beg her to become their mediatrix; she could not resist their pressing entreaties. [Butler "st-catharine-of-sienna"]

She arrived at Avignon on 18 June 1376, received by Pope Gregory XI and the cardinals with great marks of distinction. [Butler "st-catharine-of-sienna"] His Holiness, after conference with her, said: "I desire nothing but peace. I put the affair entirely into your hands; only I recommend to you the honour of the church." [Butler "st-catharine-of-sienna"] She had another point no less at heart: Gregory XI had made a secret vow to return to Rome, and consulting her on this subject, she answered: "Fulfil what you have promised to God." [Butler "st-catharine-of-sienna"] Surprised that she knew by revelation what he had disclosed to no one, he was immediately determined to execute his design; he left Avignon on 13 September 1376, overtaking her at Genoa. [Butler "st-catharine-of-sienna"]

At Sienna she continued her former way of life, serving and often curing the sick, converting obstinate sinners, and reconciling inveterate enemies, more by her prayers than by her words. [Butler "st-catharine-of-sienna"] Her knowledge of heavenly things was such that certain Italian doctors, intending to expose her ignorance, departed in confusion and admiration at her interior lights; the same had occurred at Avignon, where three prelates, envying her credit with the pope, confessed they had never seen a soul so enlightened and so profoundly humble. [Butler "st-catharine-of-sienna"]

Commissioned by Gregory XI to go to Florence, still divided and obstinate, she lived there amidst daily murders and confiscations, in frequent dangers of her own life, always undaunted even when swords were drawn against her. [Butler "st-catharine-of-sienna"] She overcame that obstinate people and brought them to submission, obedience, and peace in 1378, under Urban VI. [Butler "st-catharine-of-sienna"]

Death and veneration

The unhappy Great Schism following Gregory XI's death in 1378 pierced her heart above all things. [Butler "st-catharine-of-sienna"] Not content to spend herself in floods of tears before God for these evils, she wrote the strongest and most pathetic letters to the cardinals who had first acknowledged Urban VI and afterward elected another, pressing them to return to their lawful pastor; she wrote also to several countries and princes in his favour, and to Urban himself, exhorting him to bear up cheerfully and to abate somewhat of a temper that had made him enemies. [Butler "st-catharine-of-sienna"] The pope listened to her, sent for her to Rome, followed her directions, and designed to send her with Saint Catharine of Sweden to Queen Joan of Sicily; when the journey was laid aside on account of dangers, she grieved to see this occasion of martyrdom snatched from her. [Butler "st-catharine-of-sienna"]

Her infirmities and pains increasing while she laboured to extend the obedience of the true pope, she died at Rome on 29 April 1380, being thirty-three years old. [Butler "st-catharine-of-sienna"] She was buried in the church of the Minerva, where her body is still kept under an altar; her skull is in the Dominicans' church at Sienna, where are also shown her house, her instruments of penance, and other relics. [Butler "st-catharine-of-sienna"] She was canonized by Pope Pius II in 1461; Urban VII transferred her festival to 30 April. [Butler "st-catharine-of-sienna"]

Why the Church remembers her

The Church remembers Saint Catharine of Sienna as a virgin who, though obliged often to converse with different persons on many different affairs and transact business of the greatest moment, maintained perpetual strict union of her soul with God, always occupied on him and absorpt in him. [Butler "st-catharine-of-sienna"] For many years she accustomed herself to such rigorous abstinence that the blessed Eucharist might be said to be almost her only nourishment; once she fasted from Ash Wednesday to Ascension Day, receiving only the blessed Eucharist during that whole time. [Butler "st-catharine-of-sienna"]

In a vision, our Saviour presented her with two crowns, one of gold and one of thorns, bidding her choose; she answered: "I desire, O Lord, to live here always conformed to your passion, and to find pain and suffering my repose and delight," and eagerly taking the crown of thorns, she forcibly pressed it upon her head. [Butler "st-catharine-of-sienna"]

She has left six Treatises in form of dialogue, a Discourse on the Annunciation of the Blessed Virgin, and three hundred and sixty-four Letters, showing that she had a superior genius and wrote perfectly well. [Butler "st-catharine-of-sienna"] Her whole life seemed one continued miracle; but what the servants of God admired most was that perpetual strict union of her soul with God. [Butler "st-catharine-of-sienna"]

The Roman Martyrology for 30 April records her simply: "At Sienna, in Tuscany, the birthday of Saint Catharine, virgin, of the Order of Preachers, famous for the holiness of her life and the excellence of her teaching, whom Pope Pius II enrolled among the holy virgins." 04-30
