I was always troubled by the Fatima prayer. Something about it never sat right with me, and it was always regarding the "lead all souls to heaven, especially those most in need of thy mercy."
Why would some souls heading to hell have more need of mercy than others? All souls who end up in hell are need of the same mercy - saving grace - before they go there.
The damned are out of the range of the mercy of God.
Why do you assume the prayer is talking about DEPARTED souls exclusively? Aren't there 7 billion+ SOULS on earth right now? Those are souls too, are they not? Aren't they all in need of God's mercy, some more than others?
And yes, some men need God's mercy more than others. A man on death row is in a much more miserable state, a lower state, and so it could be said he "needs God's mercy more" than the average Trad Catholic who goes to Mass every Sunday. We all need God's grace to be saved -- but some are in more desperate need of it than others.
We all need justice. But a falsely accused man, on death row for murder, is in more need of Justice than you or I. That's the sense in which some "are more in need of God's mercy".
And no, all mercy is not equal. Imagine a king forgiving a man for a petty theft vs. a king forgiving another man who murdered a member of the Royal Court. Yes, all are guilty of sin, and on the receiving end of God's mercy. But we're not all equal! Not even close. What have you been drinking? No two sinners are equal in their guilt before God. So again, those with one foot in hell are asking a LOT more from God's mercy than a "petty crime" sinner. Our Lord spoke about this on more than one occasion. About how "he who is forgiven more, loves more" citing Mary Magdalene as an example.
And it's a fact that the whole Fatima serious of apparitions was about saving SOULS from Hell. Not shortening the stay in Purgatory or assuaging the sufferings of the Poor Souls in Purgatory. That is a good work, a praiseworthy work, but not the focus of the Fatima apparitions AT ALL.
Our Lady showed a vision of Hell to the children, and said that "Many souls go to hell because they have no one to pray for them", etc.
She did not show them a vision of Purgatory.Fatima had *nothing at all* to do with Purgatory. Only the souls on earth, most of whom are in danger of going to hell.
