While this trick can be performed with technology, I am disturbed by Pablo's quick glib answer that he's using "Witchcraft".  And the other details shared by Catholicus are downright disturbing, and merely confirm the suspicions some of us have long had about the diabolical influence on/by Pablo.

Father Ripperger cautions very strongly against people attempting to engage evil spirits without the authority of the Church, and says that they are prime takeover targets.

Given the natural powers of the fallen angels, in a battle of wits against Pablo, it's not difficult to predict the outcome.

Perhaps Father Ripperger needs to pay Pablo a visit.  Of course, exorcisms don't work on those who are willingly in league with the demons.

You weren't very clear in that first sentence -- I thought you were talking about CathInfo members. It was only after reading the whole post, and re-reading it, that I understood what you meant.

Thanks for calling that out.  It's one of those things where I knew the reference in my head and didn't realize it might be ambiguous to the reader.

So he was banned from the chapel in Phoenix and then followed Fr. Pfeiffer to Boston, Kentucky?

No.
Fr. Pfeiffer asked him to come to KY.

Has anyone spoken to Fr. Pfeiffer about his weird friend?

Soooo many have.

Hernandez is the main reason b. Williamson doesn't work with fr. Pfeiffer.  The other reason is that b. Williamson told fr. Pfeiffer to stop travelling and pay attention to his "seminary".  Fr. Pfeiffer refused.

Fr. Pfeiffer has chosen hernandez over b. Williamson, over fr. Voigt, and now over fr. Hewko.

It is all too diabolical.

Perhaps Father Ripperger needs to pay Pablo a visit.  

Just try to get in touch with fr. Ripperger...
We have been trying for months, to no avail.
If anyone can help, please PM. 
We have need to dispel OLMC evil from someone in our family.

I am thankful that my family didn't move to Boston early on, before the trainwreck became obvious even to those mostly blinded by hope. We discussed it, wanting to be of more help to the resistance seminary, but decided against moving. We decided it wasn't prudent to put all our eggs in the basket of a mere man. And it seems that it was PtM's basket after all...

He's almost impossible to get a hold of ... and he would not operate outside his diocese anyway.

But if it's someone in your family over whom you have authority, you can apply the binding prayers against the demons that inflict him.

Father Ripperger, while I don't agree with him about everything, makes some very solid points about authority, that the demons are subject to God's authority, and that you have the right to invoke the authority that derives from God towards all those people and things and places under your authority.  He makes a distinction between deprecatory and imprecatory prayer, the former a request, the latter a command.

Father R spends a lot of time talking about how you have to discern precisely the type of demons that might be afflicting your family members.  I think he's overcomplicating it too much.  As the father of my family, I have prayed as follows:  "By the authority of God invested in me as father, I command my [son's or daughter's] Guardian Angel to identify and ward off whatever demonic spirits are afflicting [him/her]." [Same for a husband's authority over his wife.]  I tell them to get reinforcements from Our Lady and St. Michael, and then request the same from the latter.  These Guardian Angels know who these demonic spirits are and can respond accordingly on a seek-and-destroy mission.  Especially in this day and age when very little is questioned by the forces of Satan than the authority and husbands and fathers, I believe that such commands have more force than ever.  After I started praying this way, I noticed a decided increase of peace in the family.  Unlike Pablo, I hesitate to take on these demons directly, since I am no match for them, but that's exactly what the Guardian Angels are there for, and they are capable of wiping them out.

Also, I pray to the Guardian Angel of our family (in the same way).  I believe that all entities constituted by God (the family in particular) have Guardian Angels assigned by God.  Our Lady at Fatima made reference to the Guardian Angel of Portugal.

I would be interested in knowing whether Father Pfeiffer knew Pablo before the summer-camp drowning that affected him so deeply.
