Many Catholic commentators refer to our present era in the Church as the Age of Mary, referring to the marked increase in approved apparitions of the Blessed Virgin over the past two centuries. The Marian Manifesto is an effort to help readers make sense of what Pope Benedict XVI called "undoubtedly the most prophetic of modern-day apparitions" - Fatima. The author examines the Fatima apparitions in light of the writings of Sister Lucia, St. Maximilian Kolbe and St. Maria Faustina, whose divinely-inspired missions overlapped in the early 20th century. From there, he examines the third part of the secret of Fatima and Sister Lucia's "last vision" at Tuy, Spain, in 1929, providing a greater understanding of Our Lord's request at Fatima for worldwide devotion to the Immaculate Heart of Mary. Such insights will help readers have greater confidence in their prayers, sacrifices and sacramental encounters with our Lord, especially when offered with and through Mary. "My Immaculate Heart will be your refuge and the way that will lead you to God." -Our Lady of Fatima, June 13, 1917
