You’re exaggerating his position on not only the amount of possession that occurs but also his remedy for it.
Oh, I am doing absolutely nothing of the sort. I've listened to his talks. I bought his book (now consigned to a landfill, thankfully). Who said anything about "possession"? You appear to be the one not understanding. I'm talking about generic demonic attacks. I am not exaggerating the pages and pages of lists he has in his book about the different demons, some types, some names (where did he get those?) ... which afflict people in different ways. I've heard him speaking about demons causing financial problems, health problems, etc. And the remedy for that is right in his book, in the form of imprecatory prayer, where the layman will issue commands to demons ... in cases where the demons afflict someone in their authority.
There's simply no theological foundation for this that, if I have authority over someone I therefore have the authority to command demons that afflict them. None. I have asked his apologists to provide the evidence, and they pointed me to some passages in St. Alphonsus and St. Thomas that Fr. Ripperger has cited, but they say no such thing. So I'm still waiting.
Demons almost by definition go about defying God's authority to whatever extent they can or are permitted to. That's what they do. They are certainly not going to willingly obey my commands just because I have God-given authority over my wife or my son. In fact, if I try to invoke that authority, they would rage all the more against me, since they hate the fact that I have God-given authority at all, and they hate the God whose authority it is. It's only if God were to force them to obey, but we do not know that He does or will ... and it's an act of presumption to assume that He will without His having revealed anything along those lines to us, either directly or through the Church's teaching.
Now, if I invoke my God given authority to, say, (politely of course) command my son's Guardian Angel to take care of him, to ward off demons, and invoke the same authority to ask St. Michael or Our Lady to do the same, since my authority over my son is God's, they will honor that and obey, to the extent that they do not know it to run counter to God's will.
So, I've exaggerated nothing. I wasn't speaking about possession, but about demonic attack in general, which can take many forms. I've heard him speak about the many ways in which demons afflict people. I see the lists in his book with all the types of demons, their names, etc. I see him encouraging people to get curious about demons, try to find out which ones are afflicting your family and your loved ones. I hear him speaking about how demons can cause all kinds of things, such as financial difficulties, and, yes, even flatulence. AND he says very clearly that Catholics can issue commands to demons, and provides prayers for them to do exactly that. Whether you do it once or do it 100 times per day, it matters nothing. Fact is that he does promote this practice, and it's the foundation for his book, why it's so innovative, and novel, and nobody has thought of this before, except the Prots.
