Predicting the future is easy. Saying when it will happen is another matter.
There are reasons to believe that the Triumph of the Immaculate Heart will come soon, with its attendant troubles.
There is only a small remnant left with the knowledge needed to restore the Church to its former glory.
And whilst God can restore the Church by Himself, He has shown that He prefers to carry out His work through men. There are lots of examples. Names such as Athanasius, Jerome, Gertrude, Bernard, Alphonsus, Teresa of Avila, Francis de Sales, Dominic, Thomas Aquinas and so many others.
For this reason I believe we'll see action in the lifetimes of those who lived in the time of Pius XII. While this remnant is still alive.
Most Catholics have lost the faith as we knew it. Confession once or twice a year, or maybe not at all. The Mass on rare occasions. All of us going to Heaven.
Contraception is the norm, and God doesn't mind; not even abortion or same-sex 'marriage'worry Him. We know this, because if these were mortal sins, they would lead to Hell, and priests would be trumpeting a warning from the housetops. But they are silent. That's how we know Hell is empty.
How awful must the earth appear to God in its present state.
When the great event comes, the burden of restoration will fall on us, who can still remember how the Mass was heard with reverence, and bishops denounced quite publicly any promotion of immorality, in season and out of season.
