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.
I think if you judge the way in which he has been persecuted you can see that the adversary sits in judgment against him, rigging tribunals, contradicting themselves, as liberals do. He's on the right side in this. Whether he's always made the right decisions - nobody always makes the right decisions. It would be interesting to see his take on this, on the events surrounding the announcement, etc.
