Teresa of Jesus of the Andes became the first Chilean saint when she was canonized in 1993 by Pope St. John Paul II. In 1919, she entered the Discalced Carmelites of Los Andes at age eighteen and died only eleven months later. An inspiration to young people, she lived a vibrant social life amid school, sports, music, and friends, all the while being completely devoted to her faith. This volume, first published in 1989, contains both a biography written by Father Michael Griffin, O.C.D., and his translation of the saint's personal diary. Father Griffin's biography captures the whole of St. Teresa's life, including her spiritual development up until her early death as a young nun. Her personal diary shows a young woman striving after holiness and a deep relationship with God. Also included are a full chronology of her life and the two homilies of Pope St. John Paul II given at her beatification and canonization.
