Well, as a Catholic, perhaps it’s not for me to judge.
But I think this is extremely dangerous. It takes a lot of training to be an exorcist. If you are Catholic, you have to be a priest and have the bishop’s permission. And calling the attention of demons to yourself is a very bad idea unless you really know what you are doing and have God’s grace and support.
Sounds like a publicity stunt to me. I hope and pray that these girls will be OK.
There’s prayers of exorcism at every baptism.
