St. Teresa of Calcutta
She left a comfortable teaching post to live among the dying poor of Calcutta, founded an order that followed her onto every continent, and did it while feeling abandoned by the God she was doing it for.
Born 1910 · Died 1997 · Canonized 2016 · Beatified 2003
Born 26 August 1910 at Skopje, died 5 September 1997, aged eighty-seven. Both full dates are given by the documents, so the age is arithmetic on days rather than on years.
A lifelong Catholic
Teresa of Calcutta was born Gonxha Agnes Bojaxhiu on 26 August 1910 in Skopje, the youngest of five children. Her father died when she was about eight, leaving the family badly off; her mother raised them, and the biography credits her with shaping her daughter's character and vocation.
At eighteen she left home to become a missionary, joining the Sisters of Loreto in Ireland, where she was given the name Sister Mary Teresa after Thérèse of Lisieux. She reached Calcutta in January 1929 and taught at St Mary's school for girls, becoming its principal in 1944. She spent twenty happy years in Loreto.
On 10 September 1946, on a train from Calcutta to Darjeeling, she received what she called her "call within a call": she was to leave the convent and serve the poorest of the poor. It took nearly two years to get permission. On 17 August 1948 she put on a white sari with a blue border and walked out of Loreto into the slums. In December she went to them for the first time — washing children's sores, caring for an old man lying sick in the road, sitting with a woman dying of hunger. Her former students began to join her, one by one.
The Missionaries of Charity were established in 1950 and eventually reached every continent. She was given the Nobel Peace Prize in 1979 and became one of the most recognized people alive. By 1997 there were nearly four thousand sisters in 123 countries.
What almost nobody knew until after she died was that for most of those years she felt abandoned by God. She called it "the darkness", and it lasted from the beginning of her work among the poor until the end of her life.
She died on 5 September 1997, aged eighty-seven. India gave her a state funeral.
What they carried
For most of her working life she felt separated from God and even rejected by Him — she called it "the darkness" — and hid it from everyone around her. John Paul II said she accepted this as a rare gift and privilege. It began as her work among the poor began and did not lift.

Francis at her canonization (2016)
- Holy See, Office for the Liturgical Celebrations of the Supreme Pontiff, biography of Mother Teresa of Calcutta, published for her beatification — the spine of this record, held in five editions. It is the source of the birth, 'born on 26 August 1910 in Skopje'; the family, 'The youngest of the children born to Nikola and Drane Bojaxhiu, she was baptised Gonxha Agnes'; her father's death 'when Gonxha was about eight years old'; Loreto, where 'she received the name Sister Mary Teresa after St. Thérèse of Lisieux'; Calcutta 'on 6 January 1929'; the final vows of '24 May 1937'; the school, where 'in 1944 became the school’s principal'; the 'call within a call'; 'On August 17, 1948' leaving Loreto; the founding, 'On 7 October 1950 the new congregation of the Missionaries of Charity was officially established in the Archdiocese of Calcutta'; the 'Nobel Peace Prize in 1979'; the scale, 'nearly 4,000 members and were established in 610 foundations in 123 countries'; and the death. https://www.vatican.va/news_services/liturgy/saints/ns_lit_doc_20031019_madre-teresa_en.html
- THE YEAR OF HER DEATH IS STATED INLINE BY TWO EDITIONS AND BY NEITHER OF THE OTHER THREE. The English reads only 'On 5 September Mother Teresa’s earthly life came to an end', taking the year from the title, 'Mother Teresa of Calcutta (1910-1997)'; the French and Spanish do the same. The Italian gives it in the sentence — 'Il 5 settembre 1997 la vita terrena di Madre Teresa giunse al termine' — and so does the Albanian, 'Më 5 shtator 1997 jeta tokësore e Nënë Terezës arriti cakun e fundit'. The date 5 September 1997 therefore rests on the sentence itself and not on an inference from a title. https://www.vatican.va/news_services/liturgy/saints/ns_lit_doc_20031019_madre-teresa_it.html
- THE ALBANIAN EDITION DATES HER 1946 CALL TO DECEMBER AND THE OTHER FOUR DATE IT TO SEPTEMBER; THIS RECORD FOLLOWS THE FOUR. English: 'On 10 September 1946 during the train ride from Calcutta to Darjeeling'. French: 'Le 10 septembre 1946'. Italian: 'Il 10 settembre 1946'. Spanish: 'El 10 de septiembre de 1946'. Albanian: 'Më 10 dhjetor të 1946-ës' — dhjetor is December. Four editions of one document agreeing against a fifth is the test this corpus uses to tell a typing error from a fact.
- SHE WAS THE YOUNGEST OF FIVE, WHICH THE ENGLISH DOES NOT SAY. The English, French and Spanish give only 'The youngest of the children'; the Italian has 'La più piccola dei cinque figli di Nikola e Drane Bojaxhiu' and the Albanian 'Më e vogla e pesë fëmijëve të Nikollë dhe Drane Bojaxhiut'. Two editions supply the number, three omit it, and none contradicts it.
- The darkness. The biography is explicit about it, and the phrases are hers, which it marks by quoting them: ‘Hidden from all eyes, hidden even from those closest to her, was her interior life marked by an experience of a deep, painful and abiding feeling of being separated from God, even rejected by Him, along with an ever-increasing longing for His love. She called her inner experience, “the darkness.”’ It places it: ‘The “painful night” of her soul, which began around the time she started her work for the poor and continued to the end of her life, led Mother Teresa to an ever more profound union with God.’ John Paul II said the same at her beatification, that she shared the Passion ‘in a special way during long years of "inner darkness"’ — ‘For her that was a test, at times an agonizing one, which she accepted as a rare "gift and privilege".’ https://www.vatican.va/content/john-paul-ii/en/homilies/2003/documents/hf_jp-ii_hom_20031019_mother-theresa.html
- Francis canonized her on 4 September 2016 in Saint Peter's Square, at the Mass for the canonization of Blessed Mother Teresa of Calcutta during the Jubilee for Workers and Volunteers of Mercy. John Paul II had beatified her on 19 October 2003, World Mission Sunday, adding her 'to the Roll of the Blesseds'; Cardinal José Saraiva Martins preached the thanksgiving Mass the next day. https://www.vatican.va/content/francesco/en/homilies/2016/documents/papa-francesco_20160904_omelia-canonizzazione-madre-teresa.html
- Feast 5 September, in the United States. The proper calendar for the dioceses of the United States of America lists her at 5 September, printing 'Saint Teresa of Calcutta, Virgin' against that date, and the Spanish section of the same calendar prints 'Santa Teresa de Calcuta, virgen'. Every calendar file held here was searched for her when this was checked, in August 2026: she appears in the United States calendars for 2026 and 2027 and in none of the twelve month pages of the Universal Calendar of the Bishops' Conference of England and Wales, nor in its summary calendar or additions page, nor in the Roman Martyrology. https://www.usccb.org/resources/2026cal.pdf
- No patronage is recorded for her. Every document held for her was searched for 'patron' and its forms when this was checked, in August 2026, across all five editions of the biography and all three homilies, and the word does not occur once in any of them. No held document declares a patronage.
- She was baptized as an infant, so she was a Catholic from the start: the biography has her 'baptised Gonxha Agnes' and records that she 'received her First Communion at the age of five and a half and was confirmed in November 1916'.
- Her name in religion came from another saint in this corpus. The biography records that at Loreto 'she received the name Sister Mary Teresa after St. Thérèse of Lisieux', and that after her final vows in 1937 'From that time on she was called Mother Teresa.'
- Her age at death is arithmetic and the documents give both full dates — born 26 August 1910, died 5 September 1997 — so eighty-seven is a subtraction of days rather than of years, and does not depend on which side of a birthday she died.
- Her interior darkness is recorded here as a share in the Cross rather than as doubt. John Paul II put it that way at her beatification: she 'shared in the Passion of the crucified Christ in a special way during long years of "inner darkness"'. The biography says the same of where it led — the night of her soul 'led Mother Teresa to an ever more profound union with God' — and that through it 'she mystically participated in the thirst of Jesus'.
