This notion that the Laity have some authority over demons has no theological foundation.
Indeed, Our Lord's Redemption freed us from being SUBJECT to the demons, but does that make the demons subject to us? I'm not seeing it.
Now, Ripperger's claim is that we can command them in the context of when we have authority over those being afflicted by them. But do we really? Recall that GOD is in complete control and command of the demons. He in turn has granted that authority to "The Twelve" in Sacred Scripture, i.e. the Church and the hierarchy. That is why "Exorcist" is a Minor Order. Otherwise, it would be superflouous if the Laity had this authority per se by virtue of their Baptism.
Just because I have rights over something, do my commands have any authority? If I see some malefactor trying to steal my car, can I command that person, "In the name of Jesus, I command you to stop and to be gone. That is my car. I claim ownership of it." I can try. But if we lack the AUTHORITY to enforce said command, it's merely a solemn request ... which in fact reduces to a deprecation. That is why it's so dangerous. St. Thomas explained that it's grave sin to issue a deprecatory request to demons because it puts us in fellowship with them.
So, if we don't have direct authority over demons, we're at great risk of being in a deprecatory mode that both St. Thomas and St. Alphonsus condemn a grave sin. In fact, they hold that it would be grave sin even for an Exorcist who does have authority over demons.
St. Alphonsus, when discussing imperative (St. Thomas uses "of compulsion") command, cites Exorcists as having authority over demons, and nowhere does he state that the faithful have such authority. St. Thomas never states what NewAdvent claims, that "all the faithful" have this authority. All he's discussing is where in principle it's possible or appropriate to command demon, but does not discuss the particulars or who or under what conditions (except that it cannot be deprecatory, nor can it be in order to extract some benefit from the demons, even a benefit that might glorify God, but ONLY to repel the demonic attacks ... except on the rare occasion that some saint might be inspired to do so).
So, returning to my prior analogy, where I try to command a car thief to cease and desist because I have ownership of the car. That thief is not inclined to respect my ownership of the car. He will cease only when law enforcement or some authority FORCES him to cease. Similarly, the demons are NOT inclined to be subject to or respect the authority of God. They hate God and are in open rebellion. Rebellion against God is what defines them. So the only way they will comply with my "command" ("imprecatory adjuration") is NOT because I have rights over (authority over) my wife and my children, as they do not will to comply with it (if they did, they wouldn't be demons but would be angels instead) is because they are FORCED TO BY GOD (and the Angels that God has empowered to be His enforcers). Am I empowered somehow to make a citizen's arrest, as it were? There's no evidence for this. We can pray to God, Our Blessed Mother, and the Angels to help us, as they DO have authority over the demons, and they absolutely CAN command them with complete authority, just as law enforcement can arrive and arrest that car thief in my example.
For to issue imperative adjurations to the demons is like me opting to take on the criminal myself instead of calling the police, who could immediately take care of the problem.
We know that Our Lord bestowed authority over demons to the Church, to the Apostles, and the Church's Tradition has been to them bestow this authority on the ministers who represent her, and as such they exercise the Church's own authority over demons.
If all the faithful have this authority, that would render the Church's practice of conferring the Minor Order of Exorcist on clergy to be completely superfluous and even non-sensical.
And, based on this premise, why CAN'T any layman pick up the Church's Rite of Exorcism and then use it against some demons that are afflicting his family, who are under his authority. What's the difference exactly? There is no difference. It's not permitted because it's always been understood that one had to have the Church's authority to issue imperative adjurations against demons.
I can turn and spin this topic in every direction, but there is not a single justification for it to be found. Even if it WERE somehow acceptable (it's not), then there's still a lot wrong with it. Catholics have always differed from Prots in that we exercise humility in acknowledging that Our Lady, the Angels, and the saints are closer to God and more likely to have their prayers heard by God, with Our Lady pretty much infallibly so. And yet with this practice we're supposed to think that we have a better chance of imperatively adjuring the demons OURSELVES than Our Lady or our Angels would? Seriously? Someone who's pushing this trash needs to justify the reward vs. the risk here. We risk stepping out of line and getting retaliated on (perhaps even possessed) by the demons by taking them on, so there's the risk. And the reward? Somehow believing we're more powerful with demons than Our Lady and the Angels are? Do we believe that demons have the ability to do anything apart from what God permits them to do, and that we have to bring them into line somehow? Just like the aforementioned car thief, if we command the demons to stop even when God has permitted them to do something, they will retaliate for our attempt to stop them ... unless God prevents it. If we try to stop them ourselves, there's a good chance we end up dead.
At one point, I had been so duped by Ripperger's mis-articulated distortions of Tradition that I believed that I could command my Guardian Angel to take care of my loved ones. Hey, why not? We have auhority to issue commands for them to protect our wives and our children, since we have authority over the latter. I have since apologized to my Guardian Angel for the hubris of this. Now Ripperger needs to retract all his nonsense, and the people who support him have to stop pushing this garbage. HolyAngels in particular continues to pertinaciously push this trash ... since out of pride, he cannot admit that he's mistaken. I admit that I was mistaken in falling for Ripperger's nonsense, and I have apologized to my Guardian Angel, and I have asked Our Lady and the Angels to please undo whatever harm may have been cause by my use of Ripperger's Deliverence Prayers.
