On Christmas Day 1886 St. Thérèse had a profound experience of intimate union with God, which she described as a “complete conversion.” Almost a year later, in a papal audience during a pilgrimage to Rome, in 1887, she asked for and obtained permission from Pope Leo XIII to enter the Carmelite Monastery at the young age of 15.
On entering, she devoted herself to living a life of holiness, doing all things with love and childlike trust in God. She struggled with life in the convent, but decided to make an effort to be charitable to all, especially those she didn’t like. She performed little acts of charity always, and little sacrifices not caring how unimportant they seemed. These acts helped her come to a deeper understanding of her vocation.
She wrote in her autobiography that she had always dreamed of being a missionary, an Apostle, a martyr – yet she was a nun in a quiet cloister in France. How could she fulfill these longings?
“Charity gave me the key to my vocation. I understood that the Church had a Heart and that this Heart was burning with love. I knew that one love drove the members of the Church to action, that if this love were extinguished, the apostles would have proclaimed the Gospel no longer, the martyrs would have shed their blood no more. I understood that Love comprised all vocations, that Love was everything, that it embraced all times and places...in a word, that it was eternal! Then in the excess of my delirious joy, I cried out: O Jesus, my Love...my vocation, at last I have found it...My vocation is Love!”
Thérèse offered herself as a sacrificial victim to the merciful Love of God on June 9, 1895, the feast of the Most Holy Trinity and the following year, on the night between Holy Thursday and Good Friday, she noticed the first symptoms of Tuberculosis, the illness which would lead to her death.
Thérèse recognized in her illness the mysterious visitation of the divine Spouse and welcomed the suffering as an answer to her offering the previous year. She also began to undergo a terrible trial of faith which lasted until her death a year and a half later. “Her last words, ‘My God, I love you,’ are the seal of her life,” said Pope John Paul II.
Since her death, millions have been inspired by her ‘little way’ of loving God and neighbor. Many miracles have been attributed to her intercession. She had predicted during her earthly life that “My Heaven will be spent doing good on Earth.”
Saint Thérèse was proclaimed a Doctor of the Church by Pope John Paul II in 1997 - 100 years after her death at the age of 24. She is only the third woman to be so proclaimed, after Saint Catherine of Siena and Saint Teresa of Avila.
St. Thérèse wrote once, 'You know well enough that Our Lord does not look so much at the greatness of our actions, nor even at their difficulty, but at the love with which we do them."
