According to Maria Divine Mercy the last part of Fatima Secret has been revealed. She is most definitely speaking of the the two Popes in Rome: The Black Pope and The White Pope like a game of chess:
From Maria Divine Mercy:
My child, the deceit, which the world will face, will be so difficult to discern, that only those who surrender to God and place all their trust in my Son, will be able to endure the trials, which lie ahead.
I gave the world the prophecies in 1917, but the last secret of Fatima was not revealed, so terrifying was it for those within the Catholic Church.
The last secret of Fatima still remains unknown to God’s children, although part of it was revealed to you on 26 January, 2012. Very few within the Church are privy to this. Now, the next part of the final secret of Fatima must be revealed, so that I can warn humanity of the consequences of ignoring my intervention to help save souls.
The Church has been infested, from the inside, by enemies of God. They – and there are twenty of them who control from within – have created the greatest deceit. They have elected a man, not of God, while the Holy Father, accorded the Crown of Peter, has been carefully removed.
The details, which I revealed, are that there would be two men wearing the Crown of Peter in the end times. One will suffer because of lies which have been created to discredit him and which will render him a virtual prisoner. The other one elected will bring about the destruction, not only of the Catholic Church, but of all churches which honour my Father and who accept the Teachings of my Son, Jesus Christ, Saviour of the world.
There can only be one head of the Church on Earth, authorised by my Son, who must remain pope until his death. Anyone else, who claims to sit in the Seat of Peter, is an imposter. This deceit has one purpose, to turn souls over to Lucifer and there is little time for such souls, who will be none the wiser, to be saved.
Children, you must only heed one warning, now. Do not deviate from the Teachings of my Son. Question every new doctrine, which may be presented to you and which professes to come from my Son’s Church on Earth. The Truth is simple. It never changes. My Son’s Legacy is very clear. Do not allow anyone to cloud your judgement.
Soon the Fatima prophecies will make sense. All is now taking place before a disbelieving world, but sadly, very few will understand until it is too late. Pray, pray, pray my Most Holy Rosary, as often as possible, every single day, in order to dilute the effect of the evil, which surrounds you.
Your beloved Mother
