Sure.

I also think that it's not a good advice to tell demons to go away. One should not address demons at all. The Hail Mary and the prayer to St. Michael are what I would recommend.

Correct, avoid all communications with demons. Pray that they leave but do not talk to them, do not react or show they are "getting to you", ignore their manifestations and be alert for any thoughts and images they will suggest to you, do not consent.

There are historical threads related to the topic of "prayers of binding evil spirits" which are supported by Fr Ripperberger and others.  The consensus is, that Fr Ripperberger is giving dangerous advice to people which is not historically catholic but protestant in understanding.  Christ gave the Church/Apostles/Bishops/priests the power to bind demons, not the faithful.  So any advice you get which tells you to "demand the devil to [fill in the blank]" is very dangerous and very foolhardy.

As others have said, the best advice is to ASK OUR LADY or THE SAINTS to intercede for you...in other words, pray for help.  Laypersons are not priests, and definitely not exorcists (which are priests who have SPECIAL powers from the Bishop).  So laypersons are, in the spirit of humility, to invoke help/protection.  Any "demands" or "orders" to demons will cause ill effects and dangerous results (because such is an act of pride) because laypersons simply don't have power over them (and the devils know this).

13 Now some also of the Jєωιѕн exorcists who went about, attempted to invoke over them that had evil spirits, the name of the Lord Jesus, saying: I conjure you by Jesus, whom Paul preacheth.  14 And there were certain men, seven sons of Sceva, a Jew, a chief priest, that did this.  15 But the wicked spirit, answering, said to them: Jesus I know, and Paul I know; but who are you?

16 And the man in whom the wicked spirit was, leaping upon them, and mastering them both, prevailed against them, so that they fled out of that house naked and wounded.

There is a lesson for "lay exorcists".

I once read a comment saying that "leaping upon them, and mastering them both, prevailed against them" means that the men were raped by the possessed.

Horrible advice.
Horrible advice.
Horrible advice.
Horrible advice.
Horrible advice and wrong facts.  There are true priests in the new Church; it's just hard to know whom they are.

You missed my point.

Does God allow for these things to happen?  Why does God allow for these things to happen?  

If you are a person who this is happening to, then pray and get a priest to help if need be, but what if a priest won't come?

What if it is just a mental illness?  What if it is just your imagination?  What if you still get attacked even though you have stopped all "cursed books"?

Have you yourself ever had a demonic attack?

Have you ever seen a person being demonically attacked?

I never meant that the power to conquer demons comes from yourself.

I don't understand your last statement "How can their be true priests in the new Church?"

This priest is a NO Priest (ordained in 2010).  Perhaps what this family needs is to stop going to the NO Mass.

I don't understand your last statement "How can their be true priests in the new Church?"

Doubtful ordination/episcopal rites do not mean 100% invalidity.  It means we don't know (and many times, can't know) who is a priest and who isn't.  So, yes, there can be legit priests in the V2 church.  If that's your only option, then you use them.

I don't disagree with this.  Again when I talk about something I use words poorly, I am sorry.  I wasn't suggesting that you get involved with the demon.  Since I am a timid sort, most of the time, when I was having issues just saying "In the name of Christ go back to hell"  was helpful and gave some relief.  

I don't really want to go into personal details, but there was problems for me for many years and no priest would ever help.  It was only the sacraments and confession that made things finely subside. I had to persevere though.  I have seen so many people drop the Sacraments, when accosted by demons.

And the major fear is what do we do when the Sacraments are no longer available. Or a priest won't come.

Maybe many Catholics should read more non fiction.
