Hello CampionTheChampion, I understand your difficulties since I grew up in a Portuguese family and Fátima is part of our family history. So I was given to understand these things while still a child and throughout my life
You have to distinguish between the “three secrets of Fátima” written in 1941 and 1944. And the remainder of Lúcias writings.
The first document pertaining to Fátima is dated: “27 of May 1917” it is the first interview (“interrogation”) by the parish priest father Manuel Marques Ferreira to Lúcia de Jesus dos Santos.
Lúcia was taken out of Portugal (she had to be hidden) on 26 of October 1925 to Pontevedra, in Galicia Spain.
In 1935 sister Lúcia wrote by order of the Bhisop the first of 4 memoires or “memórias”.
The first memória was “published” in Portugal in May of 1938 as part of a book entitled “Jacinta” by padre Galamba de Oliveira.
In November 1937 sister Lúcia wrote, again under obedience, her second “memória”.
In July 1941 sister Lúcia is ordered to write her third “memória”.
In December 1941 Lúcia finishes writing her fourth “memória”.
The complete set of the 4 “memórias” was first published in August 1976, having the text being corrected by father Luis Kondor.
You have to understand, the “carnation revolution” was in 1974 hence it was in the context of immense political turmoil that the need to publish the “memórias” arised, since the Fátima message pertained to the future and in the wake of the revolution all wanted to know what would become of Portugal.
The third secret was moved from Leiria-Fátima diocesis to the Vatican archives in Abril de 1957.
The third secret was only revealed in 13 de Maio de 2000.
