She was once hit on by a guy who turned out to be satan in a Moscow bar, and taken for a wild ride through the air while on his back, presumably in order to stifle her then-budding spiritual tendencies toward Jesus and the Catholic Church.
These kinds of things happen to her all the time, and while she doesn't tell many people about them for fear of frightening them, she does tell us. She has also told us that while she has looked for a spiritual advisor among the Catholic priesthood, she hasn't found anyone that would "work." Either the presumed advisor wouldn't believe her, thinking her loony or liar, or he would jump to the conclusion that she was filled with spiritual pride, thinking herself "special."
Now, I don't have a problem with visions, demons or the existence of the enemy. The spiritual forces are all about us, and just because most of us don't see them or hear them doesn't mean that they aren't there. If you look at the ocean you don't see the life forms teeming about, but they all are swimming there anyway. (I read that nifty little analogy recently but I can't remember where, so I apologize for not saying where I got it.)
But I do have a problem with her belief that God is not able to provide a suitable spiritual advisor for her, and I do have a problem with her belief that her judgement about what an advisor should be is more important than God's judgement, and I do have a problem with her acting on these visions and visitations without the safety of proper Church authority.
A priest ordained in the Catholic Church acts "in persona Christi," most specifically at the altar of the Mass, but also, if less officially, in terms of things spiritual. This is aside from any dull or skeptical personality, any tubbiness of belly or ego, or any tendency toward a flaccid Confessional style. If one prays to God to provide an appropriate spiritual advisor, doesn't one have the obligation as a son or daughter of the Father to expect that He wouldn't instead send in a clown? Isn't that scriptural, to expect not a stone or snake, but bread and fish from the God who would be called Daddy? If you ask for an advisor, and you get one (which is hard enough), shouldn't you assume that you've gotten the one that God thinks will be most helpful to you?
I think someone with authority should be asking her how she knows this demon is in her home, and what her willful mother would be doing with a demon, much less bringing it with her from Russia to visit her grandchildren, and why any demon would be hanging where Christ is glorified and the Virgin visits. I think she is treading in dangerous unclear territory; without proper Church oversight she is indeed open to deception and pride. I think she has little business mucking about with demons without a priest who knows what's going on.
