I have tremendous respect for a lowly priest who rebukes an apostate bishop. St. Paul publicly rebuked St.Peter for much less.
Fr. Heidt is known and loved by many as a holy man.
You're free to respect him, I have very little reason to respect a not-so-lowly Priest, in my estimation.
My Priest has suffered quite a bit because he dared to rebuke my Bishop, but he did it the way a man does it and should do it. Leaving himself unassailable, and much respected by his Parishoners because he conducted himself with honor.
If a Priest talked to me like Fr. Heidt, I'd hightail it out of there, if I could, and find another Priest who understood what Honor is really all about.
