Little Nellie of Holy God was an Irish child mystic that gave St. Pope Pius X cause to change the age requirement for First Holy Communion. After her mother died, Nellie was raised by the Good Shepherd Sisters who noticed her close relationship to God. She would have conversations with, visions and even played with the child Jesus. She longed to receive Holy God, as she called Him, in Holy Communion and did so at only 4 years of age, just months before she died of tuberculosis. Nellie’s body was found to be incorrupt one year after she died.
