This is TERRIBLE! We had better weigh ourselves down with sacramentals that have been blessed with an exorcism. St. Benedict medal is powerful if blessed in this manner by a priest who will do it. You have to ask. Many priests will do this blessing. The Franciscans of the Immaculate for instance. St. Paul says to put on the armor of God. Blessed salt is good to have in your house. Buy a box of salt and have it blessed.
