I think there should be such a thread about every traditional priest.
Sure, please feel free to list other priests who are much danger to the Traditional Catholic faithful as Fr. Pfeiffer: Who are convincing speakers, deceptive, keep a warlock in charge, run a de-facto cult, destroy vocations and marriages, who have publicly attacked dozens of priests/bishops with otherwise SPOTLESS reputations, etc. -- then we'll talk.But otherwise NO, we most certainly SHOULD NOT gossip or criticize every priest about minutiae.
Don't think for a minute there's not a MOUNTAIN of GRAVE evidence COMPELLING US to make an exception in the case of Fr. Pfeiffer, and broadcast this information about Fr. Pfeiffer to the world. It's about THE PUBLIC GOOD and THE SALVATION OF SOULS otherwise it would not be morally permissible.
Remember, Our Lord said, "Leave my priests to Me." or something to that effect. By default, we should leave their judgment to God. Unless it's blaring, obvious, crystal clear that there's a real danger, we should be silent and just pray for them. They have a right to their good name and reputation just like any of us. We MUST give them every benefit of the doubt. Because if you malign a priest's good name and you're wrong -- even for "innocent" reasons like trusting the wrong guy -- then HEAVEN HELP YOU. Your salvation would be in great jeopardy. They don't call priests Alter Christus
(another Christ) for nothing.
