2. The reception given to the example of her life and Gospel teaching in our century was quick, universal and constant. As if in imitation of her precocious spiritual maturity, her holiness was recognized by the Church in the space of a few years. In fact, on 10 June 1914 Pius X signed the decree introducing her cause of beatification; on 14 August 1921 Benedict XV declared the heroic virtues of the Servant of God, giving an address for the occasion on the way of spiritual childhood; and Pius XI proclaimed her blessed on 29 April 1923. Shortly afterwards, on 17 May 1925, the same Pope canonized her before an immense crowd in St Peter's Basilica, highlighting the splendour of her virtues and the originality of her doctrine. Two years later, on 14 December 1927, in response to the petition of many missionary Bishops, he proclaimed her patron of the missions along with St Francis Xavier.

Beginning with these acts of recognition, the spiritual radiance of Thérèse of the Child Jesus increased in the Church and spread throughout the world. Many institutes of consecrated life and ecclesial movements, especially in the young Churches, chose her as their patron and teacher, taking their inspiration from her spiritual doctrine. Her message, often summarized in the so-called "little way", which is nothing other that the Gospel way of holiness for all, was studied by theologians and experts in spirituality. Cathedrals, basilicas, shrines and churches throughout the world were built and dedicated to the Lord under the patronage of the Saint of Lisieux. The Catholic Church venerates her in the various Eastern and Western rites. Many of the faithful have been able to experience the power of her intercession. Many of those called to the priestly ministry or the consecrated life, especially in the missions and the cloister, attribute the divine grace of their vocation to her intercession and example.
