I believe Gruner attempted to clarify her supposed clarifications. She apparently was said to have dismissed his entire effort, all he was doing, etc, when she may have said or indicated nothing of the sort. This is bigger than one person, however. If she was manipulated or misrepresented in her later years, then that's the shame of those clerics and posers who did so - who have much to answer for in the next life, surely. But Our Blessed Mother appeared to these children, not to others. And she appeared to Sister Lucy more than the others. So Sister Lucy was chosen by God, because Our Blessed Lady in that way is still the handmaid of God, not to produce Revelation, as in the Apostolic Age, but to clarify it with prophecy when the time had come, perhaps. These are pleas and reminders to do the right thing, particularly to pray the 15-decade Rosary (specifically NOT RVM). We haven't. And we still don't know.
As of now, I don't see anything on his fatima.org website, however.
As far as Fr. Gruner is concerned, I believe he is way off base and is most likely the enemy.
His 3 inch thick book on the third secret is only one testament that he's not one of the good guys.
What is RVM?
