St. Catherine of Siena

She nursed people with diseases nobody else would touch, then talked a pope into leaving Avignon and coming back to Rome — a woman who could barely read, telling the head of the Church what to do.

A lifelong Catholic

Catherine Benincasa was born in Siena on 25 March 1347, the second youngest of a very large family. Her father was a dyer. At seven she consecrated her virginity to Christ, and at sixteen, after a vision of St. Dominic, she joined the Dominican Third Order — the Mantellate, laywomen who wore the habit but lived at home. That is where she stayed. She learned to read with difficulty and to write only in adulthood.

She began by nursing the sick and serving the poor of Siena. Then it widened. She traveled to press for reform in the Church and to make peace between Italian states, and people of every class came to her for direction and called her mother. Not everyone was glad of her: in 1374 her own order summoned her to Florence and interrogated her, then gave her Raymund of Capua as her guide, and he wrote her first full biography.

In 1376 the Florentines sent her to Avignon as their ambassador; that mission failed, but while she was there she pressed Pope Gregory XI to end the papacy's long exile in France and return to Rome. He returned on 17 January 1377. Sent back to Florence in 1378, she was nearly killed in a riot, and said her sins had lost her the red rose of martyrdom. Her last work, done nearly from her deathbed, was reconciling Pope Urban VI with the Roman Republic.

She dictated the Dialogue of Divine Providence and nearly four hundred letters. She wrote to the pope himself and called him "sweet Christ on earth." She was in constant physical pain and for long stretches ate almost nothing but the Eucharist. After three months of agony she died in Rome on 29 April 1380, thirty-three years old. She was canonized in 1461 — a woman who could barely write, and one of only four women the Church calls Doctor.

What they carried

The opposition came from inside. All through the years of the nursing and the embassies, the encyclopedia says, she was under continual persecution from the friars of her own order and her sisters in religion; her contemporaries said her charm prevailed over it.

Benedict XVI on Catherine of Siena (2010 General Audience)

  • Catholic Encyclopedia (Herbermann, 1907-1913), 'St. Catherine of Siena' — birth 25 March 1347 at Siena, death 29 April 1380 at Rome, canonized 1461 by Pius II, the 1375 stigmata at Pisa, the 1376 Avignon embassy and its failure, the 22 June 1378 attempt on her life, and the persecution she suffered from the friars of her own order and her sisters in religion. NOTE: gives the feast as 30 April, which is the PRE-1969 date. This article is not a source for the current calendar. https://www.newadvent.org/cathen/03447a.htm
  • Benedict XVI, General Audience of 24 November 2010 — catechesis on Catherine in the series on medieval women. Source for the Mantellate at sixteen, her difficulty reading and learning to write in adulthood, the 1374 interrogation by the General Chapter of the Dominicans, and 'sweet Christ on earth'. Independently corroborates three of the refs below whose own documents are not held here: the Paul VI Doctor declaration of 1970, the Pius XII patronage of Italy, and the John Paul II co-patronage of Europe. https://www.vatican.va/content/benedict-xvi/en/audiences/2010/documents/hf_ben-xvi_aud_20101124.html
  • General Roman Calendar (1969 reform) — feast restored to 29 April, her death date, after St Peter of Verona was moved to local calendars. NOT HELD: no document on disk states this. The Catholic Encyclopedia predates the reform and the 2010 audience does not mention her feast. This is the one claim in the record with no fetched source behind it.
  • Pius XII, papal brief of 18 June 1939, proclaiming Catherine of Siena and Francis of Assisi primary patrons of Italy. Italian only. The operative words: 'Pertanto di Nostro "Motu proprio" di certa scienza e dopo matura deliberazione colla pienezza di nostra apostolica podesta, in virtu delle presenti lettere, dichiariamo da questo momento e costituiamo in perpetuo San Francesco d'Assisi e Santa Caterina Patroni Primari d'Italia.' The brief also says why she was chosen, and it is worth having in full: 'Ne altrimenti si adopero Santa Caterina, la fortissima e piissima vergine, che valse efficacemente a ridurre e a stabilire la concordia degli animi delle citta e contrade della sua Patria e che mossa da continuo amore, con suggerimenti e preghiere, fece tornare alla sede di Pietro in Roma i romani pontefici, che quasi in esilio vivevano in Francia, tanto da essere considerata a buon diritto il decoro e la difesa della Patria e della Religione.' She reconciled the cities and districts of her own country, and by continual love, by counsel and by prayer brought the Roman pontiffs back from what was almost exile in France to Peter's see in Rome — so that she is rightly reckoned the honor and the defense of her homeland and of religion. Independently corroborated by the 2010 audience above. https://www.vatican.va/content/pius-xii/it/briefs/documents/hf_p-xii_brief_19390618_patroni-italia.html
  • John Paul II, Spes Aedificandi, 1 October 1999. The document's own title block reads 'APOSTOLIC LETTER ISSUED MOTU PROPRIO', and the Holy See files it under /motu_proprio/ rather than /apost_letters/, so that is the style used here — a motu proprio is an apostolic letter the Pope issues on his own initiative, and the shorter description makes the document hard to find again. The operative clause is quoted in full on the patronage itself. The letter completes an earlier act it names: 'completing what I did on 31 December 1980 when I declared Co-Patrons of Europe, along with Saint Benedict, two Saints of the first millennium, the brothers Cyril and Methodius'. The 1980 act is not held here. https://www.vatican.va/content/john-paul-ii/en/motu_proprio/documents/hf_jp-ii_motu-proprio_01101999_co-patronesses-europe.html
  • Paul VI, declaration as Doctor of the Church, 1970. Document not held; corroborated by the 2010 audience above.
  • 'one of only four women the Church calls Doctor' — Teresa of Ávila and Catherine of Siena (Paul VI, 1970), Thérèse of Lisieux (John Paul II, 1997), Hildegard of Bingen (Benedict XVI, 2012). Verified August 2026: no fifth woman has been declared. The overall count of Doctors is 38 as of Leo XIV's proclamation of John Henry Newman on 1 November 2025, so any future prose giving a total rather than the women's count will need rechecking.
  • THE SEAM, REPAIRED 2026-08-17 — C5. Three of the four items in struggles were orphans: the 1374 interrogation, the continual persecution from her own order, and the 1378 attempt on her life were named in the one field that cannot explain itself and were nowhere in the summary. Two are now narrated. (1) THE INTERROGATION, from Benedict XVI, General Audience of 24 November 2010, which also supplies what came of it: 'Some even thought that they should not trust her, to the point that in 1374, six years before her death, the General Chapter of the Dominicans summoned her to Florence to interrogate her. They appointed Raymund of Capua, a learned and humble Friar and a future Master General of the Order, as her spiritual guide. Having become her confessor and also her "spiritual son", HE WROTE A FIRST COMPLETE BIOGRAPHY OF THE SAINT.' The order's distrust is the reason her biographer exists, and the summary now says so. (2) THE ATTEMPT ON HER LIFE, from the encyclopedia, which the earlier reading had detached from the mission that produced it: 'Early in 1378 she was sent by Pope Gregory to Florence, to make a fresh effort for peace. Unfortunately, through the factious conduct of her Florentine associates, she became involved in the internal politics of the city, and during a popular tumult (22 June) AN ATTEMPT WAS MADE UPON HER LIFE.' The second Florence mission was missing from the summary altogether, which is why the attempt had nowhere to sit. (3) THE CONTINUAL PERSECUTION STAYS IN struggles, because it is a condition rather than an event and the summary can only narrate events — the same treatment C3 gave Elizabeth of Hungary. It now indexes the years the summary narrates instead of listing incidents beside them.
  • Three phrases in this record are the encyclopedia's own words: 'a collection of nearly four hundred letters'; 'After a prolonged and mysterious agony of three months, endured by her with supreme exultation and delight, from Sexagesima Sunday until the Sunday before the Ascension, she died'; and 'She was bitterly disappointed at her escape, declaring that her sins had deprived her of the red rose of martyrdom.' One thing the article says is left out for room, and it is named here so the omission is visible: that she endured the three months 'with supreme exultation and delight'.
  • WHAT CAME OUT OF THE SUMMARY TO MAKE ROOM, 2026-08-17. It was at 313 of 320 and the two new passages needed about fifty. Out went: the honors list — 'Pius II canonized her in 1461. Pius XII made her patroness of Italy, Paul VI declared her a Doctor of the Church in 1970, and John Paul II named her a co-patroness of Europe' — reduced to 'She was canonized in 1461', because the same card prints status and year, prints 'Patron of: Italy · Europe' from the patronages field, and prints 'Doctor of the Church' under state of life, with the popes and the dates at refs [3], [4] and [5]. The judgment that follows it was kept whole, since nothing else in the record makes it: 'a woman who could barely write, and one of only four women the Church calls Doctor.' Also out: the list of the classes of people who came to her, now 'people of every class'; the deliberate seeking of the most repulsive diseases, which is the holiness line one paragraph above; and A COLLECTION OF PRAYERS, which is the one deletion that leaves the corpus, since no ref carried it. It is the third of the three works the encyclopedia lists — 'a collection of prayers' — and it is recorded here rather than allowed to become a fact nobody held. The summary now stands at 318.
