St. Therese, also known as Saint Thérèse of Lisieux, was a French nun born on January 2, 1873. She is best known for her simple and profound approach to spirituality, often referred to as the "Little Way." Therese entered the Carmelite Order at a young age and dedicated her life to God, emphasizing love and humility in her daily actions. She wrote an autobiography titled "Story of a Soul," which details her spiritual journey and experiences. St. Therese was canonized as a saint by Pope Pius XI in 1925 and is the patron saint of missions and florists. Her feast day is celebrated on October 1.
