Johann Siegen, the Prior of Lötschental in the Valais, has gifted us a magnificent book about the Archangel Michael. He has masterfully brought the Archangel Michael to life in this book, drawing from the sources of Holy Scripture, tradition, and art, presenting him to us as a friend and fellow warrior. Pope Leo XIII. had a vision of the fall of the fallen angels to this earth. The invasion of the powers of darkness was so immense that Leo XIII. mandated that after every silent Holy Mass, three Hail Marys, the Salve Regina, and the prayer to St. Michael must be recited. Unfortunately, this directive was abolished during the liturgical reform. Since then, there has been such an incursion of demonic forces that Pope Paul VI. declared that Satan had entered the inner sanctum of the Church through a crack. In this hour of the Antichrist, there is a call for Christians.
