Our Lady of Fátima
As a young boy and in later life, Pacelli was an ardent follower of the Virgin Mary. He was consecrated as a bishop on 13 May 1917, the very first day of the apparitions of Our Lady of Fátima. Based on the Portuguese mystic Blessed Alexandrina of Balazar requests, he consecrated the world to the Immaculate Heart of Mary in 1942. His remains were to be buried in the crypt of Saint Peter's Basilica on the feast day of Our Lady of Fátima, 13 October 1958.
