This website, is all about the 3rd secret given to the three children at Fatima.
From what I have read, I feel it is coming true, and has to do with the Apostasy within the catholic leaders of the churches. It has yet to be revealed, and was to have been released in 1960, or upon sister Lucy's death. The third letter from our Blessed Mother, has never been revealed. You form your own opinion on the matter, but if as it is suspected, that the last letter of Fatima to St Lucy, was speaking of the life of the Church, and death by apostasy, then we are well on our way.
