Louis de Marillac was an important man with influence that spread across national boundaries and obtained power and control for him by wooing others to do his will. His place within the Parisian courts was firm even though he had conceived a child with a woman he wasn't married to--this child was a daughter who would be named Louise. Louise's mother died during childbirth but Louise survived the ordeal. Though she was a child of a recently deceased mother and had been born outside of the bonds of wedlock she was exceedingly well cared for by her father and the people her father appointed to care for her. She received an excellent education in a nearby monastery and felt the beginnings of a growing and vibrant spiritual life. Yet, she lacked a stable home life and often lamented this lack. Her well-appointed and pleasant life had no strong foundation, though, and this left her feeling adrift in a world that only became more and more confusing and perplexing as she grew up as a motherless daughter among Parisian nobility.
Louise sought the order and simplicity of the monastic order "the Daughters of Passion" in Paris but was rejected. She was crushed because she had begun to think of monastic vows as an escape from the chaos that marked her life. She was not informed as to why her application was rejected and this left her questioning most of her life and all of her calling. She was advised that God had "something else" planned for her. She was once again set adrift in an increasingly tumultuous world and went to what remained of her family for advice on how to proceed from her place of rejection. Her family suggested that she marry and so she consented because of the possibility that it would finally offer a family life like she had been coveting all these years. She was married and she had one child within the first year of marriage but soon thereafter her husband grew very sick. She cared for him very well but she could not quell the doubts that this marriage had been a mistake. She had vowed to remain with him and so she did but she wondered if this was what she had been called to do. In a service of worship near Pentecost she received stunning and sudden certainty. She wrote, "I was advised that I should remain with my husband and that the time would come when I would be in the position to make vows of poverty, chastity, and obedience and that I would be in a small community where others would do the same." She took care of her husband for two more years before he died.
Having fulfilled her previous vows she sought out a spiritual director to provide direction and guidance to her rudderless life. She found Vincent de Paul and he spent his time with her by guiding her to a life of spiritual moderation and calm.Her tendencies had always been toward chaos and directionless action but under the direction of Vincent she became increasingly comfortable and peaceful. Together the two of them founded a group known as the Daughters of Charity. This group focused on remembering two essential principles: (1) in any situation they should act as Jesus would act, and (2) they must remember to "Love the poor and honor them as you would honor Christ Himself." Under the guidance of Louise and Vincent they formed a group of women who endeavored to become family one to another and provide the calm and moderate direction to individuals that only a loving community can truly offer. Louise's direction expanded their charity and teaching to include hospitals, orphanages, institutions for the elderly and mentally ill, prisons, schools and the battlefield. Louise died on March 15, 1660, after having devoted her life to developing loving communities among those set adrift by life and circumstances.
