Missionaries in the future will, more and more, see that their apostolate among the Muslims will be successful in the measure that they preach Our Lady of Fatima. Mary is the advent of Christ, bringing Christ to the people before Christ himself is born. In an apologetic endeavor, it is always best to start with that which people already accept. Because the Muslims 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 Muslims the rest of the way to her divine Son. She is forever a "traitor," in the sense that she will not accept any devotion for herself, but will always bring anyone who is devoted to her to her divine Son. As those who lose devotion to her lose belief in the divinity of Christ, so those who intensify devotion to her gradually acquire that belief.
Too bad the same sensitivity isn't shown when it comes to Fundamentalist Protestants who believe in Biblical inerrancy. With them it's "we're right, you're wrong, get over it."
Was not the town of Fatima named after one of Muhammed's daugther's? This article reminds me of a bookedmarked article writen by the great Archbishop Sheen about Mary and the Muslims.
As to the many comments on this thread, I merely shake my head. Whenever a thread mentions Mary it opens the door for the old tired "idolaters" charge against Catholics. I feel comfortable in my faith that I believe salvation comes through Christ, but also that He holds a special place in His heart for His mother so we should too.
