Angelus, public prayer means the Church. For individuals to privately pray for him and encourage other people to pray for him or to pray for him as a family with friends, is not public prayer unless we gather together publicly in the name of the Church. And the very reason we are praying for him is so that he was granted the great grace of a miraculous conversion before he died. There is no time with God. And this does not undermine "No salvation outside the Church".

Forgive my ignorance but what does EENS mean?

Sorry, declaring Im going to pray for a soul is not public prayer. It's simply sharing my intentions and encouragement for people to do the same. I'm not doing it publicly here on the forum.

St. Padre Pio says you can retroactively pray for the grace of conversion. God lives in the eternal present. Just as every mass is THE Mass.

I also thought you could pray retroactively because with God, there is no time.  He always knew we would pray for the conversion of the deceased.  I still pray the green scapular prayer for some relatives that have died.

"...He often said that it was necessary to pray for the deceased, even if they had been dead for many years, because God, as the master of time, can use such prayers at any time in their lives.

One day, a woman came to see Padre Pio and asked him if it made sense to pray for her grandfather - who had died  many years past -  because he had not been particularly religious in his life. He replied, “God is the master of time, with Him there is no time as we know it.  Pray for your grandfather, and God will be able to apply your prayers as if he were still at the end of his life.”

These words greatly surprised the woman. But Padre Pio explained that God hears prayers in eternity and that He can use them for the deceased during his life, even in his last moments...."

This reminds me of a story from England(?).
  A man had just died in the hospital and he found himself standing at the precipice of hell. Fire and smoke. Jesus appeared beside him and said: " I cannot help you". Then He added:" Your family is now praying in a room, praying the Rosary for you." He repeated:"I cannot help you."

Miraculously the man came back to life through Our Lady's intercession. The man made a confession, and a soul was saved that day. Not sure, but I think he lived about four years longer, and lived very devoutly, praying Rosaries.
There are other stories similar to this one, where the dead regain life, confess etc., and are asked to choose what comes next. Amazing graces+

If it is true that Padre Pio said those things, then he appears to have contradicted de fide dogmas of the Church......
Here are the relevant dogmas and corollary theological conclusions based on those dogmas (according to Ott's Fundamentals of Catholic Dogma):

https://isidore.co/misc/Res%20pro%20Deo/ITOPL_OCR-layer only/5a.%20Dogmatic/Fndmntls%20of%20Cathlc%20Dgma_OCR.pdf

1. The souls of the just which in the moment of death are free from all guilt of sin and punishment for sin, enter Heaven. [de fide]

2. The souls of those who die in the condition of personal mortal sin enter Hell. [de fide]

3. With the arrival of death the possibility of merit or demerit and conversion ceases. [Sent. certa]

4. Immediately after death, the particular judgement takes place, in which, by a divine sentence of judgement, the eternal fate of the deceased person is decided. [Sent. fidei proxima]

Maybe, maybe not.  This is all theological speculation.  There's nothing dogmatic or obligatory about it.

Some of this is new-age mumbo jumbo, like the Mormons, who believe they can baptize their dead ancestors.  God created time because IT MATTERS.  We are all given an allotment of time.
