Plus, this is also a reminder to our Protestant brothers and sisters that when it comes to really bad demonic infestations/possesions, call in the big guns, a Roman Catholic priest who is trained to be able to do that! In other words, simply praying for delieverence is not enough!
I could not pray to God. I tried as hard as I could, but I couldn't. Out of desperation, I called upon the saints to articulate my prayers and rescue me from this living nightmare. Though I had never prayed with the saints before, I began to understand the Church's teaching of the unity within the One Body. I pleaded with the saints in Heaven to offer God the prayers I was unable to formulate.
Even I felt confident enough to approach God once again; Susan's lunge for the door awakened and invigorated me. Strangely, I found myself repeating the Hail Mary until it became a chant. Being a recent convert to Catholicism, I had yet to accept the Catholic doctrines concerning Mary and considered any form of Marian devotion to be idolatry. Though I had never before prayed a Hail Mary in my life, I suddenly found myself incapable of any other form of prayer. Somehow, Mary's intercessions allowed me to find peace during that long night; I knew that I had survived the worst and that I would exit with my faith intact. It terrified me to recall how close I came to turning away from Christ out of fear.
I left that classroom with a powerful belief in Mary's intercessions and with many questions about spiritual warfare; I also learned a lasting lesson in humility and the limits of human understanding. Was the purpose of that night served when so many individuals were inducted into the Church? Did I witness spiritual warfare? I do not have the answers, but I do believe in the reality of spirits, angels, and other related phenomena that I can neither touch nor see. -- Physical Dimensions of Spiritual Warfare, December 1994, By Bobby Jindal/New Oxford Review
