If I see someone shooting random children in a playground or see groups of teenagers carrying baseball bats and checking random houses and cars in my neighborhood to see if they are unlocked, it is not my own, personal "private judgement" that they should be stopped. Or that they are exhibiting criminal behavior.. the law itself says that these activities are forbidden..
When I see someone with supposed authority in the Church continuously contradict so many Church teachings that they can't be counted, and when they admit to knowing it, i.e., when Ratzinger said he was promoting a "counter syllabus"... when they officially reduce the Holy Sacrifice of the Mass to a meaningless "supper", complete with clowns and composed of Lutheean and Jewish prayers, it is not "private judgment " that moves me to exclaim that these are wolves in sheeps clothing, out to destroy the Church... The Church teaches that these are called heretics and since they are not members of the Church, they cannot be head of it..
Have you even read the Cum ex apostolatus officio?
