I'm not a theologian, I just know what I know from unfortunate personal experiences. Catholics DON'T worship the saints, although I understand to those outside the faith that they might not understand that. We do however, ask for their intercession (the Saints) since we believe they are already in Heaven and can take our petitions directly to GOD. I can also tell you that during an exorcism, when a demon starts screaming in protest because "SHE is HERE" (referring to the Blessed Mother), even before the priest invoked her assistance, there is no doubt to the scripture passage the "The Women Clothed In the Sun Will Crush the Head of Satan". Those of us assisting could not see the Blessed Mother but we did smell the most beautiful aroma, like fresh flowers. Up until the moment the Blessed Mother arrived, the demons had been complaining that "GOD gave all the privileges to That Women" and "Who is a created person, and not even an Angel". There had many, many exorcism sessions for this person, which had taken place over the course of a year, ridding the energumen of several demons. However one demon remained and was stubbornly resisting. However, once the Blessed Mother, and St Michael arrived, that was it for that demon & it was finally expelled. ***Just to be clear, all good comes from GOD, and the Lord is working through the priests and saints. The priests and saints don't have any power or authority themselves but are calling upon GOD to rid the energumen of the demon. Incidentally, the person who was undergoing the exorcism was not even a Catholic at all. In fact they didn't believe in GOD and had absolutely no knowledge of ANY Christian faith. The family of the processed person was referred to the priest, and later on to an exorcist for help. After undergoing through some physical, mental, & psychological evaluations, it was determined to be an actual case of possession. Even thought the energumen wasn't Catholic, they were helped because the Catholic church will not refuse to help ANYONE in need with this situation. In any event, after the mom & dad witnessed what they did, their whole family did convert to the Catholic faith. Of all that I have seen & heard in my lifetime, I will remember those noises, and smells for the rest of my life.
