My understanding of authority is that the priests have zero authority over the demons, except what has been delegated to them by their bishop, by virtue of his authority over the diocese, and the fact that the demon is trespassing in that diocese.  That being the case, it would seem that a man has similar authority over his house, over his wife, and over his children.  If any of those are being trespassed upon by demons, it would seem that a man has authority to command them to leave.  Just as a man has the authority to tell a human intruder to leave his property, but has no such authority to tell him to leave the neighborhood, it would seem that a man has similar spiritual authority and responsibilities over his home and family.  

Because Ripperger is a televangelist in Catholic garb. Incredibly popular in media, almost a celebrity in some circles, and basically making up his own theology that people go with.

Indeed.  He became famous precisely because of his dealing with the subject of Exorcism ... since it gets a lot of attention from curiosity-seekers.  It's very sensationalistic stuff.  Otherwise, he'd be just another Motarian type of neo-Trad priest, which one can find for a dime a dozen.

Unfortunately, though, he's that much more dangerous because he presents himself as a Traditionalist.  In some respects, he is, but his approach to Exorcism and demonology is just off base and can do a lot of harm and is very dangerous, but because he's "Traddy", people give him more credibility in that matter than he deserves.

Apart from the problem with lay people adjuring demons, ala Pablo the Lay Exorcist, which is strictly forbidden by Traditional Catholic moral authorities, he also fosters an excessive curiosity about and engagement with demons.

In his books, I kid you not, he has demons for everything ... not excluding a demon of flatulence.  He fosters a mentality where as soon as anything goes wrong for someone, it must be due to demonic activity.  If I experience flatulence, it must be caused by some demon, and not the large helping of asparagus or beans that I had for dinner.  If you have financial problems, it's a demon.  If you have any other issue, it's a demon.  Last I checked, even our temptations can come not only from demons, but also from the flesh and from the world.  Not everything has a diabolical cause.  But if some demon is afflicting my finances, or whatever, then it's because and only because God has allowed it to.  God is in ultimate control, so we turn to God.  Fr. Ripperger also makes a big deal about trying to find out the name or title of each demon, as if 1) by somehow knowing this we have more power over the demon (seems highly superstitious) and 2) Our Lady, the angels, and the saints, don't know which demons are afflicting us and can't dispel them regardless of who or what they are.

Between these two things, it leads to lay people developing excessive curiosity about and engagement with demonic forces ... and THAT is where the danger is.  St. Francis de Sales likened demons to ferocious dogs on a chain.  They'll bark and growl and attempt to terrify you, but they're on God's chain and cannot do anything more than what God permits.  He advises ignoring them and turning to God instead.  It's when we develop a curiosity about this dog and decide to approach and draw closer that he might actually become a threat to us.

I also found his one talk about Traditional Catholics both unfair/slanderous and inaccurate.  Certainly, there are certain temptations or tendencies among Traditional Catholics that the devil will attempt to exploit, but Father's allegation that Traditional Catholics (allegedly gleaned from hearing Confessions) are much more prone to sins of impurity than Conciliars is downright false and is slanderous.  He has a very poor sample size as Conciliars who are mired in sin simply tend not to go to Confession.  In your average Conciliar parish of 10,000 families, you'll be lucky if 5-10 people show up every Saturday for the 30-minute Confession window, and it's usually the same 5-10 people.  99.9% of Novus Ordites just don't go to Confession.  And the Novus Ordites are mired in impurity ... and don't care.  They fornicate, shack up, go from one impurity to the next, and don't Confess these as sins, and march up to "Holy Communion" by the thousands anyway.  At least the Trads who are afflicted with such sins are trying to overcome them and are going to Confession.  He also holds that it's pride and arrogance for Traditional Catholics to criticize the practices of the Novus Ordites, such as Communion in the Hand, etc.  That's nonsense.  While it can lead to pride, and we always have to realize that there but for the grace of God go we, but we don't suddenly call evil good and good evil because it would be "judgmental".  That's along the lines of Jorge's "Who am I to judge?" thinking.  In any case, Father's denunciation of Traditional Catholics came across as very arrogant and judgmental (ironically).  In general, I sense a strong arrogance in his tone of voice when he delivers talks.  I fear that he'll experience some major fall himself as a result of his engagement with demons and his own pride (he needs to inspect his own eye first for the beam).  Oh, on that point, his conversations and dialoguing with demons is also strictly forbidden by authorities such as St. Alphonsus and St. Thomas Aquinas.  Both state that unless one is acting under a special inspiration, such as a saint might be, it is strictly forbidden to engage the demon in any kind of dialogue.  Apart from anything else, the information you get from them is worthless, since demons have been known to lie.  But it's also dangerous, and forbidden, according to these Catholic authorities, and yet Father Ripperger seems to be having casual fireside chats with demons.

While I agree that the attempts of some of these pseudo-trad priests to put traditionalists in their place and get them to check their egos, borders on slander a la Jorge, and that Fr. Ripperger has been one of these, I don’t find that he blames everything that goes wrong in your life on demons.  In fact, he states the world and the flesh are just as much the cause of sin as is the Devil, in one of his most popular early talks.  “The Devil is not under every stone.  He’s under every other one.”
