After being refreshed for the first time with the Eucharistic Bread Theresa seemed to develop an insatiable hunger for the celestial food. Then, as if by inspiration, she asked Jesus to turn all her earthly consolation into bitterness. After that she burned with a most tender love for Christ the Lord and for his Church. More than anything in the world she wanted to enter the Order of the Discalced Carmelites, where by self-sacrifice she might assist priests, missionaries and the whole Church, and so gain innumerable souls for Christ Jesus. All this, she promised God would do for her, even when apparently she lay at the point of death. Her extreme youth was an obstacle which hindered her entrance upon the religious life. Even this she overcame by her incredible courage of soul. She entered Carmel at Lisieux happily at the age of fifteen. There God fashioned the heart of Theresa in a marvellous way, teaching her to ascend to him step by step. Imitating the hidden life of the Virgin Mary like a well-watered garden she bore flowers of every virtue, especially an abiding love of God and neighbour.
That she might please the most high God to greater degree, when she read in Sacred Scriptures the warning, Whoever is a little one, let him come unto me, she determined to be a little one in spirit. As such she consecrated herself forever with childlike confidence to God, her most loving Father. The way of spiritual childhood, following the teachings of the Gospel, she taught to others, especially to the novices who training in the pursuit of religious virtues she undertook in obedience to her superiors. Overflowing with apostolic zeal she pointed out to a world filled with pride and a love of vanities, the simple way of the Gospels. Meanwhile Jesus, her spouse, inflamed her with a desire to suffer both in soul and in body. Moreover, perceiving that the love of God was everywhere rejected, she became filled with grief and two years before her death, offered herself as a victim of love to the merciful God. She writeth that she was then wounded by a flame of fire from heaven, whereupon she became consumed by love, rapt as it were in ecstasy. Repeating over and over again the fervent words, My God, I love thee, she passed on to her Spouse on the 30th day of September, in the year 1897, at the age of twenty-four years. As she was dying she promised that she would let fall upon earth a ceaseless shower of roses. This promise she hath indeed fulfilled in heaven, and her shower of roses hath continued to this very day. The Sovereign Pontiff Pius XI added her name to the Virgins declared Blessed and two years later, at the time of the great Jubilee, listed her among the Saints. He also appointed and declared her Patroness of all the missions.
