I just saw the post about the allegations of misconduct, and I must say that I'm not surprised. I rather predicted it, saying that pride and hubris of the magnitude that he displays leads almost inevitably to a humbling by God, typically through a fall. I can sense the condescending arrogance in his tone of voice. He also put it on display with his self-righteous (and slanderous) condemnation of Traditional Catholics.
He became a public figure almost exclusively due to his dealing in subject (demonic possession / activity) that pique the curiosity of the masses. If he had not become famous for that subject matter, he'd be another quasi-anonymous quasi-Trad priest floating around out there. And that brought with it both fame and money, and attention ... all of which easily lead to the issues regarding which he has been accused here.
That's his personal issue, and we should pray for him, but the important thing is that lay people have no authority to issue commands to demons ... or there's a very high likelihood that they will retaliate ... if God permits it. "Deliverance" prayers are an exclusively Protestant phenomenon and term, and the Prots all hold that all "believers" have power over demons, the same way they believe that there's no exclusive priesthood. Fr. Ripperger limits this authority to commanding them regarding those under our authority, but it does not follow that if we have authority over an individual we also have authority over the demons afflicting them. He misinterpreted St. Alphonsus to come up with his theological framework to turn people into "lay exorcists" ... something that has no precedent whatsoever in Traditional Catholic theology.
We need only pray to Our Lady, the Terror of Demons, St. Michael, and our guardian angels. We can certainly appeal to our authority in requesting that the guardian angels of those under our authority protect them, and since they acknowledge our God-given authority over the individuals, they will respect that ... whereas demons most certainly do not.
