Cardinal Siri, pray for the Church...
I'm certain he is praying for the Church from heaven.
Many dismiss the possibility of Card. Siri being Pope Gregory XVII because he participated in Vatican II, said the
Novus (dis)Ordo, and recognized the post-Pius XII popes as valid popes, but would this take away from the fact that they were not canonically elected?
St. Francis of Assisi (1181-1226)
"There will be an uncanonically elected pope who will cause a great Schism, there will be diverse thoughts preached which will cause many, even those in the different orders to doubt, yea, even agree with those heretics which will cause my Order to divide, then will there be such universal dissension and persecutions that if those days were not shortened even the elect would be lost."
