Sedevacantism - Seducing From The One True Church

My blogging colleague The Eponymous Flower put forth a piece earlier touching upon the serious problems caused by Pope Francis' imprudent actions and remarks.  She makes two excellent points that we must all bear in mind as we try to deal with the seemingly nonstop barrage of nonsense emanating from the Vatican these days.

1. Faced with the incongruous proceeds from the Pope lately, many Catholics have become deluded by sedevacantism.  I said the following in a previous post but will repeat it again.  If such Catholics see flaws in the Holy Catholic Church and are distressed because they know it to be the One True Church, by what convolution of logic do they abandon that same One True Church?  Under no circumstance whatsoever can this sin of apostasy be justified.  These Catholics place their immortal souls in grave danger.  Still, another question must be answered.  For all the snarky comments I've received alleging that I don't appreciate that the Pope is a Pope of the world and not just the United States, I must wonder if the Pope realizes that he is the Pope of these traditionally-oriented Catholics who feel deep hurt at being dismissed as "rosary counters" and the such.  Do those commenters care about that question?  I will not hold my breath waiting for a reply.
2. Further down the article we see that the Pope is definitely infallible when four criteria of the Extraordinary Magisterium are met.  Otherwise, his teachings are solemnly binding only insofar as they conform to Tradition already set forth by the Magisterium.  The four criteria are below:
1. He solemnly teaches as Pope.
2. He teaches on faith or morals.
3. He teaches definitively.
4. He teaches so as to bind all Catholics.

I'll now touch upon a piece put out by Mundabor a few days ago called "The Bloggers, The Orks and The Uruk-Hai".  Not being much of a movie-watcher, I don't understand the references to "orks" and "uruk-hai" (whatever the heck they are).  I absolutely agree that we must shine the light and cry out when things contrary to the Faith issue forth from the Vatican (or even the Pope's pen or mouth).  We may no longer demure from that task.  However, I do think Mundabor crosses an unacceptable line when he speaks of "mocking him, ridiculing him, making him a laughing stock".  Ladies and gentlemen, it's one thing to shine the light on erroneous doings and sayings from the Pope; it's quite another thing to belittle him as a person.  He is the Holy Father; he is the Vicar of Christ.  His person must remain inviolate.  As we speak the truth about troublesome words and actions, we must take great care not to attack his person.  

But we must speak out.
