Fulton Sheen on the Conversion of the Muslims: Missionaries in the future will increasingly see that their apostolate among the Moslems will be successful in the measure that they preach Our Lady of Fatima. Because the Moslems have a devotion to Mary, our missionaries should be satisfied merely to expand and to develop that devotion with the full realization that Our Blessed Lady will carry the Moslems the rest of the way to her Divine Son.
As those who lose devotion to Mary lose belief in the Divinity of Christ, so those who intensify devotion to her gradually acquire that belief. (Per Christum Blog post)
