October 1. Saint Thérèse of Lisieux is perhaps one of the most known and best loved saints in the Catholic calendar. A young Carmelite nun who wanted to go to the missions, she remained within the cloister yet became the patron of the missions. Therese entered the convent at 15 and died at 24 having lived a full life, including serving her community as novice director. Her parents were canonized in 2015.
