Feast day: July 16
Saint Marie Magdalen Postel was born in Barfleur, France. She established a school for young girls in her hometown when she was just 18 years old. When the school closed, due to the French Revolution, Marie used the school building to house fugitive priests.
Marie founded the Sisterhood of Christian Schools of Mercy, where she and her sisters taught and acted as nurses to their pupils. Saint Marie Magdalen Postel is celebrated for her holiness and miracles.
