October 13, 2014- Synod of Family Relatio Report issued -“This is the first time in Church history that such a heterodox text was actually published as a document of an official meeting of Catholic bishops under the guidance of a pope.”              Bishop Athanasius Schneider
Friday, October 13, 2017 - ????   Three Days of Darkness???    Chastisement??? or possibly nothing at all.   
Many believe the 100 years given to Satan began on October 13, 1917.  
Mere coincidence - I don't think so. 

You now claim not to positively know the name of the Fatima Crusader?    Sure, I believe that.
