Fatima
muh July 13 – 107 year delta
The apparition of July 13th would prove to be in many ways the most controversial aspect of the message of Fátima, providing a secret in three parts which the children guarded zealously. The first two parts, the vision of hell and the prophecy of the future role of Russia and how to prevent it, would not be revealed until Sr. Lúcia wrote them down in her third memoir, at the request of the bishop, in 1941. The third part, usually called the Third Secret, was only later communicated to the bishop, who sent it unread to Pope Pius XII.
