The Most Potent Weapon in Spiritual Warfare! It has long been known that the Mass is a potent weapon of spiritual warfare. But how should the Mass be used? Which Mass should a priest say in a given situation? Is there anything a layperson can do? In this book, an exorcist shares his private choices of Mass propers for various situations: commanding the demons, breaking death curses, countering love spells, and even three of the Masses used by medieval exorcists when confrontng the demons. Likewise, this book contains instructions for adapting these propers to other liturgical rites – namely the Novus Ordo, Prayer Book, and Augustana Uses – along with how the laity can use these texts, examples of General Prayers for exorcistic use, and even a list of hymns that can be sung by those gathered during the Mass or even the exorcism! Point your Weapon, aim, and chase the evil spirits away!
