Who was St. Thérèse of Lisieux?
Thérèse Martin was born in Alençon, France, on January 2, 1873, the youngest daughter of Louis and Zélie Martin, who were themselves canonized in 2015. Her mother died of breast cancer when she was four and a half, and the family moved to Lisieux. The Sanctuary of Lisieux calls her school years "the saddest of her life." At Christmas 1886, after midnight Mass, she received what she called the grace of her conversion. In 1887 she prayed for a condemned murderer named Pranzini, who kissed the crucifix before he was executed. That same year she went on pilgrimage to Rome and had an audience with Pope Leo XIII.
She entered the Carmel of Lisieux on April 9, 1888, at fifteen, and never left it. Nine years of hidden life followed: prayer, domestic work, and the discovery, in 1894 and 1895, of what she called her little way. John Paul II, proclaiming her a Doctor of the Church, described it as "nothing other than the Gospel way of holiness for all": a child's trust in a Father who carries what the child cannot climb. She wrote it down under obedience, in three manuscripts that were published a year after her death as Story of a Soul. The same apostolic letter counts 266 letters and 54 poems besides.
Then the dark came. On the night of April 2 to 3, 1896, she coughed blood for the first time. Shortly after Easter, the Sanctuary of Lisieux says, she entered a "night of faith," and John Paul II writes that this "trial of faith" would "last until her death." Pope Francis, in his 2023 letter on her, quotes her own description: Jesus allowed her soul "to be invaded by the thickest darkness." She was tempted to think heaven itself was a fiction. Doubt was not new to her: her first manuscript, recalling trials from before her profession, speaks of "asking myself whether heaven really existed." In her last manuscript she said that when she sang of heaven's joy she sang "simply what I want to believe." She died in the Carmel on the evening of September 30, 1897, at twenty-four, with the words "My God, I love you." Pius XI beatified her on April 29, 1923, canonized her on May 17, 1925, and on December 14, 1927, named her patroness of the missions with St. Francis Xavier. John Paul II declared her a Doctor of the Church on October 19, 1997, the third woman given the title.
Why Catholics pray to St. Thérèse in doubt and anxiety
Catholics bring their doubts to Thérèse because she had the worst kind and did not pretend otherwise. Her trial of faith was not a mood. It lasted eighteen months, through her dying, and it was aimed at the one thing she had built her life on. Francis writes that in that darkness "she was evoking the darkness of atheism and the rejection of the Christian faith," and that "She felt herself a sister to atheists, seated with them at table, like Jesus who sat with sinners." She did not get her certainty back. She chose to act as if she believed, for the sake of those who could not, and said she was "ready to shed my blood to the last drop to profess faith in the existence of heaven."
That is what makes her useful to a person whose faith has gone quiet, or whose anxiety has started asking whether any of it is real. Francis's judgment on her doubts about heaven is blunt: "This was not a lack of faith." A faith that keeps choosing God in the dark is, in the Church's eyes, heroic, not deficient. The same holds for fear. Thérèse spent her last year sick, short of breath, and in the dark, and her answer was not to feel brave but to stay small, to let herself be carried. John Paul II calls her trial "a grace of purification that immerses her in a long and painful dark night." The Church does not promise it will feel like grace at the time.
So a Catholic asks her for what she had: the nerve to keep praying when prayer feels like talking to nothing, the humility to stop demanding feelings, and the trust behind her promise, which Franciscan Media quotes, "I want to spend my heaven doing good on earth."
How to pray to St. Thérèse
Pray to her any day. Her memorial is October 1, and the nine days before it, September 22 to 30, end on the day she died. Her Carmel, and the basilica built in her honor, are in Lisieux, in Normandy.
Say the prayer below, then tell her exactly where your faith is, including if it is nowhere. Go to Mass even when it feels empty; she did. Go to Confession and say the doubt out loud, which takes away half its power. Read a few pages of Story of a Soul, especially the last manuscript, which was written inside the darkness. If anxiety has become constant, is waking you at night, or is bringing panic, see a doctor or a counselor; Thérèse spent her last months in the Carmel infirmary under care, and the Church sees no contradiction between asking her prayers and getting treatment. If you are thinking of ending your life, call emergency services or, in the United States, 988.
Her last words were not an argument. They were a decision. That is the whole little way: not feeling, but choosing, one small step at a time.
