There is not really a reason to doubt or to wonder what Our Lady's private message to the Fatima children was as most of it can be understood by the public miracle. If we wanted to know the message Our Lady wanted to send, why not just ask some of the 70,000+ bystanders? Many have written of their accounts. For example, the editor-in-chief of O Seculo, the official communist/freemasonic newspaper of Portugal at the time, tells us what he saw. It should also be noted that he spent 3 months publicly mocking the prediction made by the children that a miracle would occur on that date, at that time, and at that place. Many in the crowd had actually showed up that day to do the same- hostile witnesses. A video that holds true to the eyewitness accounts can be found here https://www.youtube.com/watch?v=a2ZkqWr2Xdc (miracle starts at 2:54). Apocalyptic overtones in the miracle confirm the apocalyptic overtones of the message. A miracle of epic proportions for a message of epic importance!
