Saint Therese of Lisieux is one of the most popular and well known saints, having been canonized by Pope Pius XI in 1925. From Normandy in France, Therese was a Carmelite nun, answering the call at only fifteen and followed a simple and practical spiritual life. She contracted tuberculosis at the age of 24 and passed away.
Saint Therese is commonly known as "The Little Flower of Jesus" who lived her life quietly but became well known posthumously because of her spiritual autobiography.
