Myrna, the point is that the second secret calls for the consecration of Russia by all the bishops, and for repentance from the Catholic people in order to avert the war.
If the war had already started, how could anyone do these things that Our Lady had asked?
Caminus' explanation is the most satisfying for me, which is that Lucia was authorized by Mary to ask for the consecration in 1929, and she apparently told her superiors in 1929, but the request wasn't released. In this case the Church authorities failed to make it known. This makes sense, because one of the conditions of Mary's promise is that the Church authorities, not just the laity, had to comply with her wishes. Then the third secret was actively suppressed.
The Miracle of the Sun at one time didn't even convince me, because it was reported in Masonic newspapers, and I believed Fatima was of Satanic origin... Therefore, I thought the Masonic papers and the devil were working hand-in-hand and were using Fatima to create confusion. This isn't so far-fetched, it's basically what is happening with Medjugorje.
