This Act of Oblation by St. Thérèse of Lisieux was one of the key hallmarks of her attaining the heights of holiness in such a short time.
St. Therese of Lisieux (1873-1897), Doctor of the Church, Carmelite French nun, this "little flower" wrote the profound work The Story of a Soul and a number of other works, all of which are edifying and powerful.
