?? "to organize a Rosary Crusade to pray for the Consecration of Russia to take place". What's wrong with praying Rosaries for this intention?
There is nothing wrong with that.
HOWEVER, to falsely claim Our Lady wants +Fellay to do this or +Williamson to do that is the absolute pinnacle of prideful arrogance. It is a foray toward evil to even dare assume such products of a fevered imagination could ever be held in comparison to the guidance of our Heavenly Mediatrix.
