Mosaic in the basilica at Lisieux: St. Therese with the first four Popes who paid tribute to her: Pius X, who introduced her cause; Benedict XV, who proclaimed her Venerable and praised the "way of spiritual childhood;" Pius XI, who named her patron of missions; and Pius XII, who declared her patron of France.

3. The Pastors of the Church, beginning with my predecessors, the Supreme Pontiffs of this century, who held up her holiness as an example for all, also stressed that Thérèse is a teacher of the spiritual life with a doctrine both spiritual and profound, which she drew from the Gospel sources under the guidance of the divine Teacher and then imparted to her brothers and sisters in the Church with the greatest effectiveness (cf. Ms B, 2v-3).
This spiritual doctrine has been passed on to us primarily by her autobiography which, taken from three manuscripts she wrote in the last years of her life and published a year after her death with the title Histoire d'une âme (Lisieux 1898), has aroused an extraordinary interest down to our day. This autobiography, translated along with her other writings into about 50 languages, has made Thérèse known in every part of the world, even outside the Catholic Church. A century after her death, Thérèse of the Child Jesus continues to be recognized as one of the great masters of the spiritual life in our time.
4. It is not surprising then that the Apostolic See received many petitions to confer on her the title of Doctor of the Universal Church.
In recent years, especially with the happy occasion of the first centenary of her death close at hand, these requests became more and more numerous, including on the part of Episcopal Conferences; in addition, study conferences were held and numerous publications have pointed out how Thérèse of the Child Jesus possesses an extraordinary wisdom and with her doctrine helps so many men and women of every state in life to know and love Jesus Christ and his Gospel.
In the light of these facts, I decided carefully to study whether the Saint of Lisieux had the prerequisites for being awarded the title of Doctor of the Universal Church.
5. In this context I am pleased to recall briefly some events in the life of Thérèse of the Child Jesus. Born in Alençon, France, on 2 January 1873, she is baptized two days later in the Church of Notre Dame, receiving the name Marie-Françoise-Thérèse. Her parents are Louis Martin and Zélie Guérin, whose heroic virtues I recently recognized. After her mother's death on 28 August 1877, Thérèse moves with her whole family to the town of Lisieux where, surrounded by the affection of her father and sisters, she receives a formation both demanding and full of tenderness.
Towards the end of 1879 she receives the sacrament of Penance for the first time. On the day of Pentecost in 1883 she has the extraordinary grace of being healed from a serious illness through the intercession of Our Lady of Victories. Educated by the Benedictines of Lisieux, she receives First Communion on 8 May 1884, after an intense preparation crowned with an exceptional experience of the grace of intimate union with Jesus. A few weeks later, on 14 June of that same year, she receives the sacrament of Confirmation with a vivid awareness of what the gift of the Holy Spirit involves in her personal sharing in the grace of Pentecost. On Christmas Day of 1886 she has a profound spiritual experience that she describes as a "complete conversion". As a result, she overcomes the emotional weakness caused by the loss of her mother and begins "to run as a giant" on the way of perfection (cf. Ms A, 44v45v).
Thérèse wishes to embrace the contemplative life, like her sisters Pauline and Marie in the Carmel of Lisieux, but is prevented from doing so by her young age. During a pilgrimage to Italy, after visiting the Holy House of Loreto and places in the Eternal City, at an audience granted by the Pope to the faithful of the Diocese of Lisieux on 20 November 1887, she asks Leo XIII with filial boldness to be able to enter Carmel at the age of 15 years.
On 9 April 1888 she enters the Carmel of Lisieux, where she receives the habit of the Blessed Virgin's order on 10 January of the following year and makes her religious profession on 8 September 1890, the feast of the Birth of the Virgin Mary. At Carmel she undertakes the way of perfection marked out by the Mother Foundress, Teresa of Jesus, with genuine fervour and fidelity in fulfilling the various community tasks entrusted to her. Illumined by the Word of God, particularly tried by the illness of her beloved father, Louis Martin, who dies on 29 July 1894, Thérèse embarks on the way of holiness, insisting on the centrality of love. She discovers and imparts to the novices entrusted to her care the little way of spiritual childhood, by which she enters more and more deeply into the mystery of the Church and, drawn by the love of Christ, feels growing within her the apostolic and missionary vocation which spurs her to bring everyone with her to meet the divine Spouse.
On 9 June 1895, the feast of the Most Holy Trinity, she offers herself as a sacrificial victim to the merciful Love of God. On 3 April of the following year, on the night between Holy Thursday and Good Friday, she notices the first symptoms of the illness which will lead to her death. Thérèse welcomes it as a mysterious visitation of the divine Spouse. At the same time she undergoes a trial of faith which will last until her death. As her health deteriorates, she is moved to the infirmary on 8 July 1897. Her sisters and other religious collect her sayings, while her sufferings and trials, borne with patience, intensify to the moment of her death on the afternoon of 30 September 1897. "I am not dying; I am entering life", she had written to one of her spiritual brothers, Fr Bellière (Lettres 244). Her last words, "My God, I love you", are the seal of her life.
